Today, in the machine-building and metal-working industries, where technology requires the washing of parts and assemblies, more and more new and sophisticated washing machines are used, which can increase quality and productivity, reduce energy costs and negatively affect the environment.

One of the striking examples of manufacturers of such washing equipment is the Italian company TEKNOX. For over 40 years this company has been producing a wide range of jet washers for washing parts and assemblies - from small-sized washers to complex conveyor systems of multi-stage pass-through type processing. The uniqueness of TEKNOX washing machines is that the parts are washed in a closed continuous cycle. The washing process is carried out with a hot water pressure washing solution. The solution, in the tank of the washing machine, is heated (up to 80 ° C) by electric heating elements and a hydrodynamic pump, through the filtration system, supplied under pressure (up to 10 bar) through a multitude of nozzles to moving parts in the form of jets, after which, with washed off impurities, it flows back tank. On contaminated parts in washing machines there are three types of impact: mechanical and physicochemical. Mechanical impact means the impact of multiple jets of high pressure solution, and physicochemical impact means their temperature and reactivity.
Jet-type machines allow not only washing and degreasing parts from contamination with a cleaning solution, but also imparting certain properties (adhesion, anti-corrosion) to their surfaces using appropriate special solutions. To this end, leading manufacturers of the chemical industry offer a wide range of effective and safe concentrates for various materials and contaminants. All washing machines are designed in such a way that the washing of parts and assemblies is automatic. The operator only needs to set the program settings and start the machine. In the control unit of the machine, such parameters as the duration of washing, blowing, removing vapors, drying, the temperature of the solution heating, as well as automatic daily heating of the solution before the start of the work shift are programmed. The washing machines are manufactured from non-magnetic stainless steel AISI 304 and are designed with a safety margin for guaranteed operation in difficult conditions... All machines comply with EU safety regulations.

Applications

The fields of application of washing machines are very diverse. This can be washing and degreasing, finishing parts, assemblies, units before assembly or painting, processing after casting or mechanical processing. The machines are also used for degreasing, anti-corrosion treatment, pickling, phosphating, paint removal, etc. The manufacturer divides the use of washing machines into two categories: in the maintenance and repair of machinery and equipment (washing parts that have been removed from machines, tools, motors and mechanisms, etc.) and in production (washing new parts after mechanical: turning, drilling, milling, grinding, etc.).

Maintenance and repair of machinery and equipment

Parts removed from machines for repair are mostly covered with various dirt: sand, oil and grease, rubber from gaskets, sealant residues and various putties. Cleaning of parts with such contamination is best carried out in washing machines, if possible, with a high-pressure pump and heating the solution above 60 ° C, but without additional filter systems, since such a large number of dirt will easily clog any fine filtration system.
Previously, petroleum-based solvents and derivatives were used for this, which dissolved fats, and then the residual contamination was washed off the part with a washing gun. Mostly submersible equipment was used, where parts were immersed in a reservoir with a solvent, then they were rinsed with water and wiped by hand. After several washes, the liquid in the reservoir became dirty, and residues of oil and dirt settled on the washed parts. And since toxic solvents were used and there were no adequate exhaust systems, the workrooms were saturated with harmful fumes. To imagine the damage this caused to the health of personnel, we will provide some information on the toxicity of solvents.
Chlorine solvents are carcinogenic, and in the presence of an open fire (lit cigarettes, burners) they decompose and turn into a nerve-paralytic, lethal gas. Aromatic solvents - petroleum derivatives - are flammable, carcinogenic, toxic to the respiratory tract. Other solvents also cause irreparable harm to health. In Europe, the use of solvents is currently prohibited. They are used only in closed circuit degreasing equipment. In the coming years, bans will be introduced on the production of any type of chlorine solvents, as well as other solvents that affect the formation of the ozone hole and are dangerous when indoors. In some areas, such as space, military, etc., hazardous solvents are still used, guided by regulatory documents approved many years ago. In the meantime, washing with solvents can not only be replaced with washing with water-based solutions, but can also be optimized using jet equipment with two or three stages of washing and rinsing and a filtration system.
Modern washing systems with a rotating basket (platform) and an effective alkaline detergent, non-toxic and not harmful to the environment, allow achieving excellent results washing parts that are processed as part of a maintenance or repair operation.

Features of choosing the type of washing machine in the field of maintenance and repair of machinery and equipment

The model of the washing machine should be selected taking into account maximum sizes parts to be washed. As practice shows, the most popular are following models washing machines:

• UNIX 60-80 - for flushing small parts during repairs and maintenance automotive equipment (this installation is not suitable for washing engines and gearboxes in general);
• UNIX 100-120 - for washing parts of cars and small vans (car engines with a maximum of 6 cylinders);
• ROBUR 1400 - for washing any parts of engines and transmissions of cargo-passenger vehicles;
• ROBUR 1800 - used for washing the largest engines, engines of military vehicles, machines for the mining industry, etc.

Models of washing machines with two baths are usually used for more thorough rinsing, the results of which are more stringent. For example, for washing parts of aircraft, helicopters, when grinding engines, when rinsing not only achieves a more aesthetic appearance processed parts, but also removes from their surface those contaminants that could have formed after previous rinsing operations.

Manufacture of machinery and equipment

In the industrial production of machinery and equipment, great attention is paid to the cleanliness of new parts before assembly or packaging. Since the quality of product operation largely depends on the washing results, very different requirements are imposed on washing machines than in the field of maintenance and repair. Here you have to deal with the most difficult problems to solve and with a huge variety of types of machines. In addition, in the industrial sector, such an extremely important requirement as quality is put forward.

The fact is that in this sector now it is required not only to degrease the parts, but also to wash off various solid particles remaining after mechanical processing (chips, abrasive materials, etc.) from them. Moreover, these particles have to be removed both from the outer walls and from blind holes, threaded holes, from all kinds of passages, water and oil distribution channels, the presence of which is distinguished by many mechanical parts. Suffice it, for example, to look at engines and other automotive components, which have many blind holes and pipelines for water cooling or lubrication systems. Based on these few examples, it is not difficult to understand that now immersion washing is not enough, even if it is used in combination with ultrasonic treatment or basket movement, since solid residues from the treatment will still be present in a suspended state in the washing bath, which will inevitably settle again. on an already washed part.

Washers with a rotating basket allow achieving the required rinsing quality. The immersion principle is excluded here, and the chips do not settle on the washed parts. In addition, this equipment is equipped with a bag filter, which is used when small metal particles cannot be captured by a conventional mesh filter.
Simple parts (sheet or stamped) do not pose any problem for a successful rinsing, since here it is only a matter of degreasing the surface. The only thing is to arrange the parts in such a way as to avoid the "glass effect", that is, they should be installed so that the liquid after rinsing does not stagnate inside the part, but flows freely. In addition, to avoid areas of blackout, parts must not block each other from the water jets. The selection of a washer for complex parts such as cast iron and aluminum alloys, perforated parts, and machined parts must be more careful.

Features of the choice of the type of washing machine in the production of machinery and equipment

For many simple parts of a simple shape with a small number of through holes, as well as for small batches of various parts, standard washers with a rotating basket (platform) are used.
For more complex parts, in some cases, you can use modified models of washing machines that are adapted to perform washing in options involving positioning or calibration.

Special configuration washing circuits

And only in those cases when especially high and stringent requirements are imposed on the quality of washing of parts and assemblies, You MUST use the above mentioned special washers that provide calibration and positioning. In this case, machines must be specially designed taking into account both the type of parts (their features, structure and configuration) and the type of technological cycle (the number of phases, baths, pressure, filtration method, etc.). For such specific cases, during serial production of identical or similar parts, you can focus on equipment of the type:

• ROBOJET - for washing large parts and parts with a large number of blind holes (gearboxes, differentials, gear cases, components hydraulic systems etc.).

• ROBOCLEAN – small washer for a small area for washing critical small parts.

Washing machine for parts and assemblies, units, washing complex units.

• ROUNDJET - for washing small parts (installation with a single loading and unloading area).

• TUNNEL – for washing small and medium-sized parts, parts manufactured in series with a large number of blind holes and threaded holes (components car enginesmade of aluminum, pump parts, etc.).

• ROTOR - for washing delicate small and small parts made of aluminum, brass, bronze, steel with external thread or threaded holes.

• LINEARJET - for washing long products (axles, cardan and crankshafts, bed, etc.) of various weight characteristics.

There are models of washing machines with two or more baths (tanks). The need for these machines arises in the following cases:
- It is required to wash parts made of aluminum or alloys of copper, brass, bronze, etc., and it is necessary that the parts come out shiny, without stains. In this case, after washing, rinsing with demineralized water is necessary;
- when parts are made of cast iron or steel and it is required to provide protection against corrosion for at least 30-60 days. For this, a suitable agent is added to the second rinse tank to prevent or retard oxidation (corrosion). Protective products are of different types: oil-based, providing protection for 30-60 days, and dry protective equipmentprotecting for a maximum of 30 days.

Recently, detergents have appeared on the market that simultaneously degrease the surface of parts and provide protection against corrosion, that is, the washing cycle is shortened and is reduced to processing in only one bath. This makes it possible to simplify the design of the washing system and reduce the cost of processing parts.

There are models of washing machines that provide the phosphating process. Technological processes of phosphating can be carried out in different ways, but in our installations only jet methods of processing parts are used, not submersible. Metal surfaces are phosphated before painting to ensure good and longer adhesion of the paint to the surface. The washing machines under consideration use the principle of spraying acid-based phosphating substances mixed with water. The practice of their application turns out to be much more economical in comparison with the use of solvents, moreover, they are much less hazardous, and at the same time, they are able to provide quite equivalent results. The only problem to be considered in this case is that there should be more than one, two or three (and even more) baths, and the chemical composition of each of them must be monitored almost daily.
The result is a better grip paintwork... One more advantage of the proposed technological processes should be noted: it is possible to reduce to zero toxicological problems in the working room.

You can talk endlessly about the advantages of TEKNOX washers. But, perhaps, the best confirmation of their quality is the names of consumers - for several decades, the company's products have been supplied to world-famous engineering enterprises, such as BREMBO, LAMBORDINI, Same Deutz Fahr Group Italia Spa, Same Deutz Fahr Group Italia Spa, Bonfiglioli Riduttori Spa. , Ilva Spa, Oto Melara Spa, Rietschle Thomas Italia Spa

Professional repair and dirt are incompatible concepts. Cleaning and washing engine parts and other units is an important step renovation works in any car service and service station. The quality of subsequent work largely depends on this operation. Thoroughly cleaning the repaired parts from contamination will help special equipment... At the RusTechnika Group of Companies you can buy various washers for units and parts. Our catalog contains equipment from well-known, proven manufacturers.

In GK "RusTechnika" equipment for washing parts of small and large units

Washing the unit by hand using gasoline, diesel fuel and a brush is a resource-intensive and labor-intensive process, it is not suitable for a car workshop. You can get rid of dirt with modern effective ways... Automatic and semi-automatic equipment is used for quick and high-quality cleaning of units in car services and factory workshops. Depending on the model, there may be:

• mobile (on wheels with a small tank);
• highly specialized for large industries (stationary automatic washing plants for the defense industry, aerospace industry, mechanical engineering, fuel and energy industry);
• universal (designed for different types units and parts of trucks and cars).

It is necessary to choose flushing equipment taking into account the conditions in which it will work. Therefore, when choosing a suitable washing machine, it is advisable to take into account: dimensions of the washing space, dimensions and weight of the units to be washed; the number of nozzles and the principle of supplying the cleaning solution; availability of additional options (oil separator, mechanical drive, basket, etc.). For example, automatic carousel washers, which include various stages of processing (washing, rinsing, drying), are effective for cleaning products with complex shapes.

To knock down the primary dirt, you can use a high-pressure washer, in a specially designated area, but clean the parts in an automatic washing plant much easier. High pressure jet cleaning of parts in a washer is the best option for removing all kinds of contaminants from cylinder blocks and other surfaces of engine and transmission parts (grease-oil, coolant, small chips, uncoked sand and dust deposits). Cleaning of parts with movable nozzles (or with different angles) allows cleaning solutions to penetrate into hard-to-reach places. Washing engine units and parts in
