Automatic car washing machine is a machine that uses computer controlled brush and high pressure water to clean the car. It is mainly composed of control system, circuit, gas path, waterway and mechanical structure. It has the characteristics of simple operation, beautiful appearance, little damage to vehicle paint and so on. But, in some cases, automatic car washer does not come out of water when it works. Do you know what causes it? How to solve it? We will answer these two questions today and hope to help you to a certain extent.
In fact, there are many reasons for this, such as the filter net at the inlet joint of the automatic car washing machine is too dirty, the faucet does not open, the control circuit has trouble, the influent solenoid valve has trouble or the water level switch contact erosion, and the professional personnel should be asked to repair it.
1, the automatic washing machine inlet water source is closed, the water inlet is blocked.
2. Damage of water inlet solenoid valve
3, computer board failure
4. The relay of the inlet solenoid valve is damaged.
5. It is recommended to check the fuse
To extend the life of automatic car washing machine, in fact, it is very simple, only need to pay more attention in peacetime maintenance should not be too big problem, but the maintenance of automatic car washing machine is not so easy Oh, the following to see the focus of the introduction of the bar. First of all, it is necessary to strictly follow the operation instructions, because this can prevent some unnecessary misoperation, because the misoperation is easy to cause unnecessary loss; if the car washer once the idle state, it is necessary to release the water in the water pipe, and regularly apply butter to the shaft chain of the car washing machine.
Automatic car washer as a high-tech equipment, the reason why the car washing machine can reach a better car washing effect is that it has entered the leading model identification skills in its computer program. As long as the car washing machine with this skill is faced with a variety of cars on the market, it can accurately identify and select the corresponding method of car washing. If the vehicle identification skills are difficult to ensure, the role of the car washing will be difficult to ensure, and it can have a negative effect on the car. The recognition skill of this vehicle has been updated many times with the development of automatic car washing machine. Every update is a response to the change of market demand.
Vehicle identification skills are developed. Proximity sensor detection technology is relatively dull for vehicle identification, and it is very simple to detect vehicle identification errors, so that car washing is simple to damage the car body. Because this skill is more dangerous to the formation of the carbody, it can not satisfy the market demand, so it is quickly screened. Later, there was a current sensor detection skill. This skill is an improvement in the proximity sensor detection skills that can manipulate the car brush movement and reach the car wash effect through a large amount of current, but the skill has no vehicle identification function. The induction skill of the ultrasonic sensor breaks through the limitation of the first two kinds of car washing skills, and has a strong sensitivity to the induction of the model, and can better distinguish the vehicle and then reach the best car washing effect.
