The cleaning of painting workshop of car washing shop is very important to the spraying effect of car body. As long as there is a car body, such as skid, grill, mechanization, workshop, equipment, etc., it must be highly clean. Otherwise, even if the dust, paint and other pollutants can not be seen by naked eyes, the final spraying effect of car body will appear particles, miscellaneous wire, miscellaneous paint, oil holes and other defects, which will cause the car body to return Repair, so that the direct cost and manufacturing costs of double waste. The deep cleaning of painting is a necessary condition to ensure the spraying effect of car body. In the cleaning process, due to the particularity of painting workshop, it is difficult to clean the high-temperature paint attached to the equipment, so it is necessary to equip with high-pressure water equipment for cleaning. The relevant technical requirements are as follows:
1. Working conditions: clean the floor grille, mechanized system and skid in the spray booth.
2. Cleaning medium: high temperature paint (baking temperature is 140-150 ℃).
3. One high pressure cleaning machine.
4. Cleaning machine pressure: 500bar.
5. The flow rate of cleaning machine is 22 L / min.
6. Driving power: motor.
7. The length of high pressure pipe is about 10 meters. (it can be adjusted according to the actual situation)
8. The high pressure water gun is a three hole rotary type.
9. Matching power supply: 380V, 50Hz
10. Water source: ordinary tap water.
11. The high pressure pump shall be imported and can work continuously under continuous high pressure
12. The high pressure pipe shall be easy to move, assemble and maintain
13. Equipped with water tank and automatic emergency low level shutdown switch
14. The electric control cabinet shall be equipped with water shortage display, and the pump will stop working automatically under the condition of water shortage
15. There is a precision filtration device for the inlet water
16. The seal is tight without water and air leakage
17. Stable operation and low noise
18. The seal is self-lubricating
19. Carry out all-round training, so that our personnel can be skilled in operation, use and maintenance, and can deal with common faults
Working parameters of high pressure water gun:
Model: mo50 / 22 voltage: 380V power: 22KW working pressure: 500bar (adjustable)
High pressure water gun is mainly used in painting workshop

1. Pre cleaning before painting in painting workshop:
Used for: cleaning the surface of white parts in welding workshop, which contains a lot of iron filings, welding slag, antirust oil, etc.
Advantages: the traditional manual cleaning method has low efficiency and incomplete decontamination. Iron filings, welding slag, antirust oil and other stains follow the workpiece into the pre degreasing tank, which directly leads to the blocking of the heat exchanger filter and affects the heat exchange effect.
The use of high-pressure water cleaning equipment can not only greatly improve the cleaning speed, but also clean thoroughly.
2. Cleaning grid plate, sled and fixture for paint removal:
Used for: residual paint on grille plate and skid in painting room of painting workshop.
Advantages: the traditional manual cleaning method has low efficiency and incomplete decontamination. Iron filings, welding slag, antirust oil and other stains follow the workpiece into the pre degreasing tank, which directly leads to the blocking of the heat exchanger filter and affects the heat exchange effect.
In the painting room of the painting workshop, there will be residual paint in the grid plate, skid, etc., and the paint will continue to accumulate and thicken. It needs to be cleaned regularly, otherwise it will affect the production and product quality. Traditional paint remover, manual knife shovel, fire and other paint removal methods not only have high cost and low efficiency, but also cause damage and deformation of the workpiece and air pollution of the working environment. The use of high-pressure water cleaning equipment can not only greatly improve the cleaning speed, thoroughly remove paint and other dirt, but also protect the working environment.
The main advantages are as follows
1. Labor saving, only need 1-2 people to operate
2. Cost saving, water as medium, no chemical agent
3. Environmental safety, no waste liquid treatment, no damage to operators
4. It can be used in any spray pool
In view of the present situation of painting workshop, this paper puts forward the solution (ultra-high pressure water cleaning and paint removal)
Use model: mo50 / 22 ultra high pressure cleaning machine, with special spin nozzle for paint removal, pressure 500 bar, flow 1320 L / h.
Scheme: directly use high pressure water jet to clean the grid
