One of the important components of a garbage truck is a solenoid valve whose function is to control the operation of the power take-off. The power take-off affects the lift system of the garbage truck, so when the solenoid valve fails, it will affect the efficiency of the garbage truck. So how do we deal with garbage truck solenoid valve failure? Next, the manufacturer teaches you how to deal with this situation:

1. The garbage truck solenoid valve cannot be closed. This may be one of the following reasons:

(1) The seal of the main spool or the iron core has been damaged. Treatment: Replace the seal.

(2) Whether the fluid temperature and viscosity are too high. Treatment method: Replace the solenoid valve of the opposite port.

(3) There are impurities entering the solenoid valve to produce the valve core or moving iron core. Treatment: Stop cleaning.

(4) The spring life has reached or deformed. Treatment: Replace the new spring.

(5) The orifice equalizes the infarction of the hole. Treatment method: timely cleaning.

(6) The working frequency is too high or the life is up. Treatment: Reorganize the product or update the product.

2. The garbage truck solenoid valve does not work after being energized.

(1) Check if the power wiring is badly connected. Treatment: Rewire and connector connection.

(2) Check if the power supply voltage is in the positive and negative working range. Treatment method: adjust the normal position range.

(3) Whether the coil is desoldered. Treatment method: re-welding.

(4) The coil is short-circuited. Treatment method: change the coil.

(5) Whether the working pressure difference is not suitable. Treatment: Adjust the differential pressure or change the solenoid valve.

(6) The fluid temperature is too high. Treatment method: change the proportional solenoid valve.

(7) There are impurities that cause the main spool and the moving iron core of the solenoid valve to be stuck. Treatment method: Stop cleaning. If there is seal damage, change the seal and install the filter.

(8) The viscosity of the liquid is too high, the frequency is too high and the life is reached. Treatment: Replace the product.

The above is how to deal with the malfunction of the garbage truck solenoid valve. When you encounter the above situation, you can compare and check it. When problems are found, they must be handled correctly in time to avoid affecting the efficiency and service life of the garbage truck.
