How to remove rust from metal?

Cleaning and protecting metal mechanical parts from rust is a common operation but also necessary in the industry to ensure the proper functioning of the parts and guarantee their durability. Many solutions using chemical and mechanical processes exist today to derust metal parts. However, in addition to being often time-consuming, they generate risks for: the health and safety of operators, damage to parts and the environment.

How does rust form?

Rust forms as a result of a so-called oxidation-reduction reaction, which is a slow chemical process involving the iron molecule (whether in pure iron or an iron-based alloy), present in the metal, exposed to air oxygen and water. It therefore intervenes when the metal is exposed to humidity for a long time.

Certain circumstances will also favor the appearance of rust, such as:

  • Different oxygen concentration conditions such as at sea, where the presence of salt water further accelerates the process
  • The presence of certain metals such as iron which is very easy to oxidize, unlike lead or stainless steel.

As soon as oxidation appears, it corrodes the metal, expands it and causes it to change its appearance. For example, copper turns orange then green on contact with oxidation. Then the oxidation will gradually spread, weakening the metal part until it punctures and crumbles.

Why remove rust from your metal parts?

The consequences of rust forming on metal parts are significant in all industries.

The embrittlement of mechanical parts due to rust can, under the pressure of production processes, reach their breaking point and cause stoppages in production lines or breakdowns in vehicles. This can lead to significant intervention costs, but also in terms of production losses, as well as leading to risky situations for the safety of operators.

The effects of rust thus lead to overconsumption of iron and steel production: more than 15% of steel production would serve only to replace parts damaged by rust, which can represent large sums for the company.

The consequences on the environment are also considerable in terms of the generation of waste from excessively damaged metal parts.

Implementing effective methods of rust removal as part of preventive maintenance along with protective coating can therefore help to ensure the durability of parts, saving money and saving new replacement purchases. expensive equipment.

How to effectively remove rust from metal?

A rustproofing process in industry always includes a process for cleaning mechanical parts and tools upstream, which are generally covered in grease and dust. The parts also require impeccable cleaning so that the adhesion of the protective coating takes place in the best conditions.

Removing rust from metal parts is a complicated task, especially when the surface of the part is not flat.

Fortunately, there are currently many solutions for derusting and degreasing metal parts:

  • some using chemicals such as phosphoric or hydrochloric acid baths
  • some of the multi-step mechanical processes such as sandblasting, shot-blasting or mechanical brushing followed by intense polishing of the parts
  • or other automated industrial cleaning machines such as ultrasonic tanks or immersion machines.

Chemical rust removal process

A chemical deoxidation process based on phosphoric acid, hydrochloric acid or caustic soda makes it easy to remove rust but presents many risks, both for the operators and for the parts.

These products will stop oxidation and remove rust but are highly corrosive and irritating to the skin, eyes, respiratory and digestive tracts if exposed. It is therefore necessary to consult the Safety Data Sheets (SDS) of these products before handling them as a precaution.

They are also dangerous for the environment, especially for the fauna and flora of aquatic environments because they increase the pH of waterways. They are also very aggressive on metal parts and risk damaging them, in particular for precision mechanics where these processes are to be banned. It is also mandatory to trace the end of life of these products according to the regulations.

Mechanical process to derust mechanical parts

remove rust from metal parts

The mechanical way using pickling techniques is the most common way to remove rust from mechanical parts, although they can be time consuming and often tedious for operators.

This includes sandblasting and shot-blasting, which consists of projecting jets of sand or high-pressure iron shot onto metal parts. These surface treatment operations expose operators to risks with the exposure of dust generated and dispersed in the air, which can cause respiratory tract disorders. High-pressure abrasive blasting can also cause severe pitting to appear on the surface of the metal and damage the more delicate parts of the components beyond repair.

There are also techniques using abrasive sandpaper or metal radial brushes but they cause traces of more or less deep grooves in the metal.

All these mechanical operations must often be followed by intensive polishing to achieve a satisfactory finish of the metal parts in order to be able to coat them with protection.

Process using industrial cleaning machines

Faster, simpler, more efficient, industrial cleaning machines can both clean grease and dust from your metal parts but also remove rust effectively.

For this, ultrasonic cleaners are the best solution for degreasing and completely eliminating rust while preserving metal parts, even their most fragile elements. Ultrasounds form pressure variations which propagate in materials immersed in a liquid. These high-frequency vibrations produce millions of tiny microscopic bubbles whose particularity is to immediately implode on contact with the part, releasing high energy which causes the oxides to detach even in inaccessible corners. At the same time, the implosion of these bubbles generates movements in the bath, conducive to cleaning. Thanks to fully automated cleaning cycles, operators can also concentrate on other key tasks.

Cleaning machines using immersion/agitation baths can also be used to remove rust, while keeping the parts intact and without operator intervention.

Upholstery and carpet cleaning with injection and extraction vacuum cleaners

Cleaning upholstery or carpets is usually a delicate task and we recommend always leaving it in the hands of professionals. Not using the right product and method on textile fibers depending on their nature or type of dirt can cause us to even permanently damage the surface. or colour.

Today we can find hundreds of dry cleaning products, foams and endless techniques and home methods on the internet, but in most cases it is necessary to clean with a wet system to clean and disinfect properly, we insist depending on the type of material.

We can find 2 processes to carry out wet cleaning professionally, a manual process indicated especially for synthetic upholstery or fabrics protected with anti-absorbent treatments and a mechanical process, in which we are going to delve a little deeper in this post, which has results. deep hygiene and disinfected and is indicated for upholstery and carpets with absorbent textile fibers.

To carry out this mechanical process of wet cleaning for upholstery and carpets, it is necessary to use professional machinery, in this case injection and extraction vacuum cleaners, capable of introducing or injecting cleaning and extra-disinfecting products into the fabrics or absorbing the same time dirt and dry the surface. Although it may seem like a process similar to using soapy water and a cloth, the result in the case of cleaning with injection and extraction equipment is much deeper and visible almost immediately.

How do injection and extraction aspirators work?

The operation of these machines, despite being for professional use, is quite intuitive.

They can be used as vacuum cleaners for solids or liquids, they normally have a polyester filter, a clean water tank in which the detergent or chemical product that is necessary for cleaning and another dirty water tank are also deposited.

When the clean water tank is filled and mixed with the right product, we have a small suction hose connected to a pump that will absorb the mixture, to be injected through the hose on the surface of the upholstery or carpet, At the same time, dirt and injected liquid are absorbed and dragged away, this also does a drying job, although the reality is that it will always be necessary to dry after washing or let it dry naturally.

Industrial parts cleaning

How to optimize the bath service life

Quality-oriented industrial parts cleaning is the prerequisite for the success of downstream processes and ensures the proper use of finished products. The specific requirements for cleanliness determine which technical requirements must be created for cleaning. Economic considerations when making an investment should also include ongoing operating costs. Modern equipment for process monitoring and bath care can, for example, extend the service life of baths.

Parts cleaning process with aqueous cleaners

Industrial parts cleaning is often done with water in which washing-active substances are dissolved. These bind the impurities from previous processing steps. The water absorbs the dirt load. When the ability to absorb contaminants is exhausted and the cleaning effect is no longer sufficient, the bath is changed. The period between two bath changes is often determined on the basis of experience. If the period of time selected is too long, there will be a loss of quality in the subsequent process steps. To rule this out with certainty, the bath liquid is often changed too early.

The right time can be determined by clearly defining and monitoring parameters that describe the condition of the pool. This point in time can be greatly delayed by using modern processing technology. The aim is to eject the dirt load and used cleaning agents from the bathroom. A number of material separation processes are available for this purpose. The type of contamination and the cleaning agents used are decisive for the selection of suitable processes.

Industrial cleaning of metals

In most cases, metals are machined using cooling lubricants. An oily film remains on the surfaces on which fine chips and dust accumulate. Other contaminants from which metal must be cleaned can be deep-drawing oils, rolling oils and polishing pastes.

Contamination also includes oxidation products such as rust on ferrous metals or verdigris on copper alloys. The agents for industrial parts cleaning must be tailored to the materials of the components.

Processing techniques

The dirt that is removed from the surfaces during parts cleaning can be roughly divided into solid, non-water-miscible liquid and water-miscible substances. The processing methods used to extend the bath service life are based on the state of aggregation and the miscibility with the cleaning solution. Often used:

  • gravity separation,
  • coalescence separation,
  • centrifugal separation and
  • filtration.

If special requirements are placed on the cleanliness of the cleaning solution, more complex processes can also be considered, such as

  • microfiltration,
  • ultrafiltration,
  • reverse osmosis or
  • distillation.

The equipment used can be installed directly in the circuit that circulates the cleaning liquid (full-flow processing) or operated in a bypass independently of this circuit (side-stream processing). In order to optimize the processes that serve to extend the bath service life, both variants are often used side by side. The aggregates in the off-line processing can be switched on or off as required.

Gravity and coalescing separation

Free oils and coarse solids that get into the bath when cleaning workpieces can be physically separated due to their different densities. The advantage here is that the process does not affect the composition of the cleaning solution. The separators consist of a container in which the liquid can rest. Light oils float to the surface and can be sucked off or drained from there. In coalescence separators, this process is supported by built-in components on which the oil collects.

Heavy components from the parts cleaning sink to the bottom as sludge. From there they can be removed with screw conveyors. In three-phase separators, both processes take place in parallel.

Extend bath service life through centrifugal separation

Solids or oils can be removed from the cleaning liquid faster in centrifugal separators, also known as separators, than in gravity separators. The principle is also based on the different densities of the phases. The heavy components are flung against the outer wall by fast rotating movements, while the lighter phase collects in the middle. Both phases are collected and drained separately. The shorter processing time is offset by higher acquisition costs.

Filtration for a longer service life

Industrial parts cleaning often produces dirt in the form of suspended matter, which can be retained in filters. In order to avoid clogging of the pores in the filter material, coarse-pored filters are used first, followed by devices with increasingly smaller pores. Due to the good cleaning performance of the filters, significantly longer bath service lives can be achieved. The disadvantage is that the filter material has to be disposed of together with the dirt.

Microfiltration, ultrafiltration and reverse osmosis

Microfiltration, ultrafiltration and reverse osmosis are among the membrane technologies. The nature of the membranes means that the smallest particles, organic molecules or salts can be removed from the cleaning liquid. In the preparation of baths for industrial cleaning, these techniques only play a role if ultra-fine cleaning with very small particle sizes in the residual dirt is required.

Distillation for water recovery

Distillation is mainly used in the treatment of bath liquids for industrial parts cleaning to recover the water. The process is based on the different boiling points of the components. With this technique, substances dissolved in the water can be separated. It helps to extend the bath service life because the concentration of these substances can be limited to a permissible level.

Monitoring of the bath condition

When monitoring the condition of the bath for industrial parts cleaning, the concentration of the cleaning agent and the amount of dirt in the bath are determined regularly. If the value falls below or exceeds the previously specified limit value, measures are required to restore the permissible operating conditions.

This includes the automatic or manual dosing of the cleaning agent or the commissioning of cleaning stages for the bath liquid that are temporarily used in the bypass. In addition to the bath control, checking the residual contamination on the cleaned parts provides information about the condition of the bath and the effectiveness of the process.

Dry car wash: all the pros and cons

What to do if you really need to wash your car, but there is no possibility to do it at a car wash? In this case, car chemistry comes to the aid of motorists, with the help of which it is possible to put on the marble without using water: the so-called dry car wash. A blurb tells that the method works and is effective, and the main thing is that it is cheaper than usual “car wash”. But do not be flattered and believe everything what they tell marketers.

At one time, this service was offered by enterprising young people in the parking lots of shopping centers. Which, in principle, was quite convenient – while the owner of the car is exploring the galleries of hypermarkets, his car becomes clean in minutes. The method is also used by those who live far away from traditional car washes or simply to save money. But as with everything, washing without water has both pros and cons, which prevail.

Let’s not go into the chemical processes that occur when applying detergent to a dirty body – advertising says something about molecular interactions. But the dirt is really washed off. In addition to everything else, the tool is suitable for cleaning the interior and even the under-hood (before using it, however, it is worth carefully reading the instructions). And after washing, a protective layer is formed on the bodywork, similar to the one that occurs during polishing. However, this is where the advantages of dry cleaning come to an end.

In rainy-snowy season, when roads are muddy and wet, a pretty decent deposit is formed on the body, against which a dry car wash is powerless. And the attempts to take the dirt by brazen force lead to damage of varnish-and-paint covering. And people who are too diligent will be able to prepare a body for painting, using just a microfiber cloth.

It also does not work with bitumen stains. So if you have driven over the repaired section of the road and have stuck them on the body, it is necessary to spend another special means.

But especially intensive dances with tambourine begin when it comes to how to wash the joints of body parts, where traditionally there is an abundance of dirt. The same method of washing doesn’t work here as well. The reason is the inability to wash out the detergent and the amount of dirt that it has collected.

Dry washing is like a crutch – the problem of cleanliness is solved selectively and not always qualitatively. Of course, the method has the right to life, but only if the dirt on the body of your car is not old. For example, on the way to work, the “swallow” was poured with water by a cleaning machine. But even here there is a risk of spoiling the paintwork, for polishing which even at a cheap car wash you will be charged a decent amount of money.

Why do you need a parts washer?

Every workshop is always busy with customers, as vehicles are always in need of maintenance. Small or major breakdowns are always taken care of by the workshop technician, and besides the breakdown of one part or another, vehicles also need routine maintenance.

For service stations an indispensable part of equipment is a parts washer, the productivity of which at times reduces the discomfort of working moments. This equipment saves an enormous amount of time, which is very handy at times of high workload for craftsmen and others.

What parts washing equipment can do

Parts washing is sometimes necessary for small parts, and sometimes entire assemblies require complete cleaning without detailed disassembly. A part washer is tailored for just about every purpose, and can be used to clean a number of parts at once.

There are two varieties of workshop washers. One is a stationary type for procedures of large assemblies and parts such as gearboxes or other large parts. The second type is mobile – which allows you to wash parts directly on the lift, without removing them. The mobile units are also suitable for cleaning of very small parts.

Cleaning chemicals for parts

Parts washers are used in different ways. For instance, for mobile parts washers, adding detergent will be enough, while stationary parts washers need special cleaning chemicals which can wash away rust, oil and other traces of use.

It is worth noting that the chemicals do not spoil the metal, but they are too toxic. Therefore, the liquid should be drained off after washing, so as not to damage the general drainage system or the environment. This liquid must be disposed of in accordance with chemical waste regulations.

The operation of sinks should be carried out in a safe manner, and above all the use of chemicals should be remembered. Hands, eyes and breathing protection should be ensured, and by all means no unauthorised persons should be present in the area.

How to buy a vehicle parts washer

When selecting equipment for washing vehicle parts, you must be aware that sink sizes vary. A single unit or several units may be suitable for a workshop, depending on the tasks and workload of the workshop.

How to clean the engine of your car?

In this article, we will learn you step by step how to clean your engine compartment, the engine of your car as a detailing pro.

Why wash the engine first?

You may have noticed it, but often the engine is the first part of the vehicle to be cleaned during a complete car wash.

It’s very simple and logical when you wash your engine, water, dirt and products are inevitably vaporized on the windshield, paint, wheels, parchoc.

Wash car paint Then the engine would returned to dirt on the paint and take the risk of adding elements that could create striped microphones on the bodywork, which is counterproductive.

Precautions before cleaning an engine

Before cleaning your engine, check that the latter is cold or lukewarm. If the engine is hot, start with the interior of the vehicle for 30 minutes, then return to the engine.

Steps of a Pro Detailing Pro Cleaning:

Remove dirt from hand

There are always leaves, earth, or other in the corners of a motor compartment, near the windshield wiper, AIT entrance zones, etc.

Remove these dirt in hand as long as they are dry, it’s much easier than when the earth in contact with water becomes muddy.

You can use an air compressor or blower, if you have one.

Protecting your car electronics

Before moving from the water on your engine, protect the electronic / electrical parts with aluminum paper or plastic bags.

Alternators, battery, air filter, fuse box, etc. Are parts of the engine that are interesting to cover. This is an additional precaution.

You can also surround your oil level rod by Scotch (Masking Tape) to guarantee that no drop will enter anywhere.

Sprinkle the engine

Now that sensitive parts are protected, you can start washing itself.

Do not try to apply pressure with your water supply or Karcher, the goal is to wet the different parts of the engine compartment. Rinse!

Clean the engine elements

Immediately after rinsed the engine, enter your brush brush, your toothbrush, rim brush or other brush to clean and shake dirt in order to take off.

CAUTION: When using your All Purpose Cleaner or Degreaser cleanser product, do not let it dry!

Do not forget that by principle the engine part is always a little hotter and so that evaporation is a little faster than you might think it, then rinse the parts of the engine again and under the hood if it starts to dry too fast.

Rinse

By finally rinsing, enjoy it to verify that you have not forgotten parts of the engine. If so, start with your brushes and cleaning product.

Be careful to rinse the parchoc, the front lights and the wheel extensors, because often engine dirt jumps on other parts of the car during rinsing.

In addition, do not wash the engine or more generally the car in full sun.

Dry the engine

Now that grease and dirt are parties, use compressed air or our darling the master blaster to quickly dry the engine parts, or a simple microfiber cloth dedicated to the motor washing and drying in the open air .

Gently remove plastics or aluminum leaves and continue wiping by hand using your microfiber cloth (used only for the engine).

Demare the engine

Before going further in the washing of your car, start the engine for 2 to 3 minutes, to make sure everything works well, which makes it possible to quickly mount the engine temperature and thus accelerate greatly. evaporation of the remaining water.

Feed and pose plastics

The goal here is to give back to black plastics that have become gray an original black, deeper.

Apply nourishing product for plastic or tire product to a foam buffer and make a massage of all plastic areas.

Beyond color, it will also protect plastics in the future and make the next washes easier.

Wipe the surplus with a microfiber napkin dedicated to the engine.

Aquablasting – a modern method of gentle surface cleaning

The traditional method of sandblasting industrial surfaces, which is harmful to human health, is being replaced by aqua-blasting – gentle cleaning. It is a modern method of soft cleaning from rust, scale, carbon deposits, paint and other hard-to-clean contaminants from various surfaces: steel, aluminum, glass, plastic. The process consists of applying a pressurized, directional jet of suspension consisting of water and abrasive particles to the surface to be cleaned.

The technology of aquablasting allows fast, soft and ecological cleaning of parts without harming soft materials and harmful emissions into the environment, protects the surface from rusting and oxidation, does not change the geometric dimensions, and reduces roughness. Slurry circulation makes the cleaning process cost-effective and low-cost.

The application of the technology has a number of advantages:

dust-free blasting
high cleaning quality
gentle cleaning so that the surface remains undamaged
harmless for people and the environment
Multiple use of the abrasive, a considerable saving of financial and operating costs and time

The scope of aquablasting is diverse, it is surface cleaning in the automotive industry, repair and maintenance, restoration work, removal of paint, rust, carbon deposits, descaling after hardening for engineering products, removal of small burrs and tool traces after turning and milling, satinization and passivation of stainless steels (including after welding works), treatment of special materials and alloys, as well as surface preparation before gluing, painting, chemical and galvanic coatings.

PARTSWASHERS team developed and tested the aquablast unit. The unit is a chamber with a closed cleaning cycle. Washing components – a fine fraction of glass beads (glass beads) sized 200-300 microns and ordinary tap water.

Machine body is made of stainless steel including a tank for storage and mixing of washing components. The lid with glass and holes for hands with protective gloves, allows you to make the cleaning process as convenient as possible. The machine is equipped with a natural ventilation system and lighting inside the chamber.

The cleaning process is as easy as possible. The parts are placed on the turntable. The operator closes the lid of the machine and starts the mixing process (lifting the settled) on the bottom of the glass beads by turning on the pump. The aqua-blasting gun is equipped with a cleaning solution supply fitting with glass beads and an air supply fitting. The operator presses the foot pedal to deliver the water/glass bead mixture through the gun to the surface of the part to be cleaned. A turntable allows the operator to easily rotate the part to be cleaned. Once the cleaning process is complete, the part is ready for further processing operations.

The main criterion for selecting this equipment is the maximum dimensions and weight of the part to be cleaned.

Why it’s actually extremely dangerous to wash car radiators

We are constantly told that car radiators must be cleaned of dirt, otherwise there will be no problems with the engine or automatic transmission. But not all washes are equally useful. What kind of breakdowns can be caused by such water procedures.

There can be several radiators in a car – automatic transmission, charge air cooler, air conditioner condenser and finally, a radiator of engine cooling, which is installed last. That is it is blown with an oncoming stream worse than all others. Because of this, they arrange “washer-dryer”.

However, it is necessary to clean radiators, otherwise there will be no trouble. The first thing to consider is the water pressure. If the jet is very strong, it will bend the honeycomb of several radiators at once. And it will make their blowing even more difficult. As a result, they will not cool better. On the contrary, the heat exchange will become worse, and you will not be far from overheating.

And in the worst case, say, if the radiator is old, the jet will just blow through it. And then the expensive spare part will have to be replaced or a sealant will have to be filled in a cooling system. By the way, if the leak is big, the sealant will not help.

One more nuance. If the car has no air conditioner, its cooling radiator, as a rule, can be washed without removing it from the car. This is convenient, but you need to consider that the wash will get dirt on engine parts like the drive belt, alternator, high-voltage wires and spark plugs. The electric motor of a cooling fan can be easily flooded with water too. Therefore, do not aim a garden hose directly at it.

And to prevent mud from getting into the engine compartment, it would be nice to put a screen of polyethylene film behind the radiator. It will block the way of water and dirt to the engine.

By the way, the engine radiator gets clogged with dirt not only from outside, but also from inside. It accumulates rust and scale particles, as well as oxidation products of aluminum parts. If you do not watch out for this, overheating of the engine is possible, especially in the summer heat. That is why, keep an eye on the dates of antifreeze and transmission fluid replacement. If the run of the car approaches 60,000 km, it does not hurt to renew them with obligatory flushing of the system.

These works are usually performed simultaneously with external parts cleaning, which includes radiator removal. Note that it is not necessary to use harsh chemicals for removal of caked up dirt, otherwise it will pierce aluminum radiator tubes and thin heat-removing plates. You should not use too stiff brushes, which will bend radiator plates. It is better to use regular car shampoo and a medium-hard brush.

The topic of a separate conversation is the heat exchanger of the engine turbocharger system, or as it is often called, the intercooler. This type of radiator, due to the design features of the system itself, in the engine compartment is often located horizontally. It is clear that in such position its honeycomb clings on itself much more various dirt getting under a hood.

It is especially noticeable in summer when poplitee fluff gets there, and it provokes malfunction of the intercooler. The down mixed with oily dirt creates its reinforcing mixture. It tightly clogs the outer channels of the radiator cells, due to which the heat dissipation immediately deteriorates. As a result, the engine power drops noticeably. To fix the problem, it is necessary to turn to masters, which costs a pretty penny.

However, there is an alternative, and very inexpensive option of radiators cleaning, offered by the German company Liqui Moly. It has developed the original aerosol composition Kuhler Aussenreiniger. The product has a high penetrating ability, allowing you to effectively act on the oily dirt. After just a few minutes of treatment, it is already peeling from the outer surfaces of the radiator cells and is then easily removed even with a weak water pressure. The product is, by the way, suitable for cleaning both intercoolers and other types of car radiators.

The benefits of a car wheel wash. How a wheel wash works

Before balancing or replacing tyres, the wheels should be thoroughly cleaned and washed. This is a mandatory procedure that affects the quality of service and the “life” of the machines. However, cleaning is time-consuming, especially when there is a greater influx of customers (spring and autumn). A wheel washer can help to automate the process and increase the efficiency of the workshop.

What is a wheel wash?

This is special equipment used to clean dirt and dust from wheels. The enclosed unit is equipped with a heating element and a motor that allows the cleaning process to be automated. The operator only needs to place the wheel on a special platform and start the machine.

The size of the machine determines the size of wheels that can be serviced. For a small tyre fitting shop or a medium-sized garage, a normal tyre cleaner capable of cleaning tyres with a diameter of 560-800mm and a width of 135-305mm will be adequate.

What you need a car wash for?

The income of a tyre workshop or car service depends on the number of services provided. Tyre washing not only makes it easier to prepare the wheels for balancing, but also earns good money. Tyre cleaning is in high demand – especially in the autumn and spring.

The equipment offers an opportunity to:

  • Expand your range of services and increase your income.
  • Reduce wear and tear on balancers and tyre changers. Keeps dirt out of the gears and increases service life.
  • Reduce water consumption. The closed loop system means that the water can be used several times.
  • Increased precision in balancing.
  • The machine will help to relieve the workmen and increase the productivity of the workshop.

How the equipment works?

All car wheel washers operate according to the same principle. Cleaning is carried out in several stages:

  • The wheel is placed in the washing compartment. The installation can be carried out manually or hydraulically. The second option is used in equipment designed for cleaning the wheels of bulky equipment.
  • The tyre is locked in place. Vertical supports are used to hold the wheel.
  • The tyre is cleaned. The machine rotates the wheel and sprays warm water through nozzles.
  • The soft granules and the water jets remove the dust and dirt.
  • The waste solution is collected in a pan.
  • The wheel is dried with air.
  • The granulate is washed and the dirt is removed.

The quality of cleaning depends on the water pressure, quantity of granulate and washing concentrate. Cleaning one tyre takes 20, 40 or 60 seconds, depending on the selected mode. Washing a truck wheel takes 60 to 240 seconds. Drying takes 15-30 seconds, depending on tyre size.

Advantages and installation features?

An automatic wheel washer not only improves the quality of cleaning, it also saves the craftsman time. There are also a number of other benefits to the machine:

  • The soft granules used by the machine do not damage the rim coating or the rubber.
  • The closed circuit reduces fluid consumption. Used water is cleaned and can be reused.
  • Washing is done in seconds. Depending on the selected mode, the cycle takes anywhere from 20 to 60 seconds. This considerably increases the capacity of the workshop, especially in season (autumn and spring).
  • The process is fully automatic and does not require any operator intervention. The operator only has to load the wheel, select the mode and start the machine.
  • Cleaning is carried out without the use of chemicals. The lack of additional agents increases the service life of the rubber and reduces costs at the workshop.
  • Quality cleaning protects the machines from damage. Dirt and dust are prevented from entering the machine.
  • Washing increases balancing accuracy.

The machine boosts your income and extends your repair shop’s range of services.
A wheel washer is an efficient but expensive machine. The cheapest machine costs about $5,000. Considering the cost, it is not profitable to use a wheel washer in a small tire shop.

Where best to install the equipment?

A few recommendations must be followed to ensure the correct and efficient operation of the washer-dryer:

  • Only install the equipment on a level surface. The truck wheel washer should only be placed on a metal trestle.
  • The premises must have a suitable power supply (380 V). The power of the car wash motor is 6 kW and the power of the truck wash motor is 8.5 kW.
  • The unit must be located close to the drainage system.
  • A rubber mat should be placed in front of the sink.
  • The compact equipment can be installed even in a small car workshop, it is only important to follow the recommendations.
