I. Introduction to Car Washing Machine

Car washing machines are divided into automatic car washing machines, self-service car washing machines, coin operated car washing machines, and automatic car washing machines. They are machines that use computer-controlled brushes and high-pressure water to clean cars. It mainly consists of control system, circuit, air circuit, water circuit, and mechanical structure. The car washing machine has the characteristics of simple operation, beautiful appearance, and minimal damage to the car paint. In recent years, it has been widely used in the automotive service industry.

II. Principle of Car Washing Machine

According to the working principle of car washing machines, they can generally be divided into three categories: tunnel car washing machines, steam car washing machines, and computer car washing machines. They use a high-pressure device to turn water into gas, forming small water mist columns to clean the surface of the car body. The body volume is less than 1 cubic meter, and an electric vehicle can be randomly equipped, which can move freely over a large range and consumes a lot of water. At least 40 liters of water are needed to clean each car.

1. Tunnel car washing machine

It was first invented by Americans. Its advantages include fast car washing speed and the ability to wash cars continuously. The time for washing a single car is basically 2 minutes and 40 seconds. However, this type of car washing machine has strict requirements for the site, and during the initial construction of the site by the customer, the cost is relatively high, with more water and electricity consumption. The cost of tunnel car washing machines is relatively high.

2. Steam car washing machine

Simply put, it is a device that can generate high-temperature and high-pressure water vapor that can be used for car washing.

3. Fully automatic car washing machine

The full name is fully computerized automatic car washing machine. A fully automatic car washing machine is a machine that uses computer programs to achieve automatic cleaning, waxing, air drying, and wheel rim cleaning. With the rapid development of the Chinese economy, more and more cars have entered households. The rapid increase in cars and the increasingly fast pace of people’s lives have made fully automatic car washing machines more and more popular among car owners. Fully automatic car washing machines are divided into non-contact automatic car washing machines and brush type fully automatic car washing machines.

III. Type Car Washing Machine

Car washing machines are classified into high-pressure car washing machines, computerized car washing machines, door-to-door car washing machines, etc. They use a high-pressure device to turn water into gas, forming small water mist columns to clean the surface of the car body. The body volume is less than 1 cubic meter, and an electric vehicle can be randomly equipped, which can move freely over a large range and consumes a lot of water. At least 40 liters of water are needed to clean each car. It can comprehensively clean the surface and interior of the car, and even the corners that are prone to dust accumulation but difficult to clean, as well as the areas that the original car washing tools cannot clean properly, can be well cleaned by the car washing machine. Car washing machines are also divided into steam car washing, reciprocating car washing machines, mobile car washing machines, tunnel car washing machines, self-service car washing machines, fully automatic car washing machines, etc.

IV. Car washing machine selection

1. Car washing machines should have reliability

The environment where the car washing machine is located is relatively humid and complex, so its stability and reliability are very important. Choosing a good car wash machine can achieve better lifespan and reduce the occurrence of malfunctions in such complex environments.

2. Work efficiency of car washing machine

The efficiency of car washing machines directly affects the revenue of businesses. Therefore, when choosing a car wash machine, it is necessary to pay attention to its equipment self-control, technical level, switch control, and program control.

3. After sales service and maintenance of car washing machines

A good car washing machine also needs good maintenance and after-sales service in order to maintain the equipment well. Therefore, the after-sales service team and strength of enterprises are also important factors that affect the use of car washing machines and store operations, as well as the lifespan of car washing machines. 

V. How to operate the V car washing machine

A car washing machine is a machine that uses computer-controlled brushes and high-pressure water to clean cars. It mainly consists of control system, circuit, air circuit, water circuit, and mechanical structure.

Fully automatic computerized car washing uses a large amount of flowing water to wash the car body. After washing, the machine will also undergo an automatic air drying program, which can blow out all the water flow remaining in all the gaps of the car body, protecting the internal components of the car and completely avoiding the phenomenon of mud and sand scratching the car paint. The fully automatic computerized car washing machine has advanced technology, beautiful appearance, and multiple fully automatic car washing programs to choose from. It detects through a photoelectric system and calculates the optimal position and force of various actions through computer analysis, achieving the best car washing effect. Fully automatic computerized car wash can automatically avoid rearview mirrors, flagpoles, etc., ensuring car safety; Computer car wash has strong cleaning power, high water content, and does not damage the car. The degree of wear on the paint is less than 30% of manual car wash. The computer car wash brush has uniform pressure, stable washing speed and direction. The test results show that after 50 computer car washes, the wear of the car body paint is less than 0.03 millimeters, while the wear of manual car washes is greater than 0.10 millimeters. The Yunnan Jinsheng computerized car washing machine has the characteristics of simple operation, beautiful appearance, and minimal damage to the car paint. Widely used in the automotive service industry.

VI. Car washing machine maintenance

In order to improve the economy, the computer car wash has made a fierce decision to extend its service life. It is recommended to adopt conservative management practices in daily life and provide valuable suggestions for Huaxin customers.

Firstly, check and maintain the project daily.

1. After filming, the compressed water was checked for pressure.

2. Check all sensors.

3. Prosecutor’s wax water and cleaning agent tank liquid.

4. The internal organization and foreign objects of the conveyor belt were inspected.

5. Ensure the normal operation of water and power sources, without any potential safety hazards.

6. Card cleaning and sanitation inspection.

7. Maintain the appearance of the equipment and keep the interior clean.

8. The arrangement of cleaning items in the venue has played a role.

VII. Troubleshooting of Car Washing Machine

1. The uneven foam spraying of the car washer is likely to be the fault of the foam system. Focus on the inspection: if the air pressure of the car washer is too low or too high, try to adjust the air pressure adjustment device.

2. The proportion of car wash fluid may be abnormal, and the proportion of car wash fluid can be adjusted.

3. If the foam pipe leaks or leaks, please check whether the pipe is firm and loose.

4. The nozzle of the car washing machine stops rotating, check and clean whether the nozzle is blocked, and replace the damaged rotator; Adjust the angle of the nozzle appropriately.

5. If there is an abnormal sound from the water pump, it is possible that air has been sucked in. It is necessary to immediately check if there is water in the water tank, clean the filter screen, and prevent blockage

If the high-pressure water pressure of the water pump is too low, adjust the pressure of the valve, the tightness of the belt, and check whether the valve needs to be replaced.
