If the hydraulic transmission system is used or maintained incorrectly, it will malfunction. In the course of using, we should pay attention to the observation and find out that anomalies should be analyzed and eliminated in time.

1. system pressure reduction

If the pressure drops suddenly, check whether the actuator is normal. The operation of the actuator is normal, indicating that the pressure sensor or pressure gauge of the Mercedes Benz parts in the north of Baotou is damaged and the actuator can not work. It may be the failure of the mechanical drive system to drive the hydraulic pump, or the failure of the overflow valve spring broken voltage regulation. If the pressure of the system is gradually reduced, it may be caused by serious oil pump wear, excessive leakage, deterioration of hydraulic oil, high temperature, too small viscosity, serious blockage of the oil filter and so on.

2. system pressure is too high

Generally due to improper adjustment of overflow valve, excessive load or excessive viscosity of hydraulic oil.

3. the pressure of the system is normal and the actuating element does not move

Generally, the solenoid valve and control circuit of Baotou Mercedes Benz parts are faulty, and the actuators are jammed and overloaded.

4. the pressure of the system is normal and the executive element is weak

Often because of the serious wear of hydraulic components, or too much mechanical resistance of the actuators, it causes stuck.

Vibration and noise of 5. hydraulic devices

There are many reasons for vibration and noise. The more common reasons are: excessive air mixed in oil, holes in the system, excessive oil suction resistance, mechanical failure or improper installation of hydraulic pump or hydraulic motor, and low level in the tank.

6. high temperature of oil

It may be due to the high pressure setting of the back pressure valve, the blockage of the unloading loop, the excessive loss of overflow, and the damage of the cooling system.

7. oil leaking

Oil leakage is caused by sealing failure.

8. electromagnetic reversing valve inflexible

There may be impurities in the matching of the sliding valve; the body's installation surface is uneven, the torque of the bolt is not equal or too large, so that the valve body of the northern Baotou Mercedes is deformed; the electromagnetic valve is worn seriously, the electromagnet is not installed or the voltage exceeds the allowable value.
