Do car repair shops need ultrasonic cleaning machines?

The small ultrasonic cleaning machine uses the physical cleaning effect of cleaning technology and the chemical action of the cleaning medium, which is a perfect combination of the two.

The equipment of Jiangsu Jiujiu Jiayi Ultrasonic Technology Co., Ltd. is suitable for: brand car service station automatic boxing and boring center and various parts. Large engines, generator sets, etc.

Commercial hardware machinery ultrasonic cleaning machine is suitable for optics, machinery, auto insurance, electronics, jewelry jade, hardware parts, accessories, electronic tools, circuit boards and other cleaning applications.

If it is small, it is basically a household ultrasonic cleaning machine, which is used in daily life at home.Household ultrasonic cleaning machines There are also commercial small cleaning machines, that is, commercial cleaning machines used in opticians and jewelry stores, and small machines used in medical laboratories.

Not applicable to all glasses: Some glasses made of special materials or special coatings may not be suitable for cleaning with ultrasonic cleaners, and extra attention needs to be paid to how to use them.

The cleaning equipment of Jiangsu Jiujiujiayi Ultrasonic Technology Co., Ltd. is the cleaning objects in the auto repair industry: the internal carbon oil channel and complex parts of the engine, the sediment in the lubricating oil channel of the cylinder block, cylinder head, crankshaft and other parts, the transmission gear group and differential gear group of the whole vehicle overhaul, up to the cylinder block, front and rear axle, Small as rocker arm, valve.

What's wrong with the insufficient water pressure of the car washer?

1. The pressure of the car wash machine is small. Possible causes of failure: the filter of the inlet pipe is too dirty, and the amount of water intake is too small. Or the strength of the inlet pipe is not enough, and when the car wash is working, the inlet pipe is sucked in. Or the inlet pipe is not well sealed and the air leaks. The accompanying symptoms are that the water pressure is sometimes large and sometimes small.

2. If air is inhaled into the high-pressure water pump or inlet pipe, you need to pull the trigger of the high-pressure water gun, lower the working pressure of the high-pressure cleaning machine and run it for a while until a stable pressure is generated.

3. (2) The water supply is insufficient. At this time, it is necessary to check whether the pressure of the water source is sufficient. Some high-pressure washers do not have self-suction function. At this time, adding a booster pump can solve the problem. ( 3) The water supply filter is blocked. At this time, just clean the water supply filter.

4. External causes Most of the external causes are unclean water supply, insufficient water supply, and blocked water supply filter, which is a very common fault, and ordinary users will not notice it. They think it is a failure of the cleaning equipment. When they go to the equipment to check, they did not find out the cause.

5. There are two reasons for the water output of the high-pressure washer: one is the external reason, and the other is the internal reason. External reasons are mostly manifested in insufficient water supply or blockage of water supply filters, which are all external causes and relatively common reasons.

6. Insufficient water inlet flow of access equipment leads to insufficient water flow, resulting in insufficient output pressure. Sufficient inlet water flow should be supplied in time to solve the problem of reduced outflow pressure. There is air in the clean inlet filter of the high-pressure washer. After exhausting the air in the clean inlet filter, the output standard outlet pressure should be ensured.

What are the advantages of the special cleaning machine for cars?

1. Environmentally friendly and efficient cleaning has been realized, and the engine performance has been effectively improved. The thorough cleaning system includes the engine cylinder head, cylinder block, and the lubricating oil hole in the crankshaft. The performance of the automobile ultrasonic cleaning machine is stable and high density, the bombardment intensity is high, the cleaning speed is fast, the cleaning has no dead angle, and it is safe and energy-saving. Easy to maintain.

2. The foam cleaning section uses compressed air to generate a certain pressure inside the equipment. Through the equipment configuration system, the equipment's matching cleaning solution and foam are sprayed onto the car or object that needs to be cleaned. The equipment adopts pneumatic control, stable pressure and large flow. It is simple and convenient to use and other advantages.

3. If the vehicle produces carbon accumulation and is cleaned irregularly, the carbon accumulation will reduce the engine performance and lead to insufficient engine power. If there is a lot of carbon, the intake valve is easy to block. In order to make the engine work normally, the injection volume can be adjusted to increase power and fuel consumption. The excessive carbon accumulation of the engine will lead to excessive emissions.

4. The intensity of manual cleaning work is high, there are many questions such as safety hazards and unhealthy, inadequate cleaning, etc.Question, ultrasonic cleaning replaces manual cleaning to further improve the work efficiency, 360-degree no dead angle cleaning, high-temperature disinfection, air drying and other links.
