The oil seal of the shaft end of the hydraulic pump of the 2-party automatic mixer truck is very fragile. Strict compliance with relevant regulations can effectively prevent many oil leakage.
If used for a long time, the oil seal will be worn.
Solution: just replace the new oil seal.
If the oil is not changed for a long time, the quality of the filter element will decline, the oil will become too dirty, and the oil seal will wear faster.
Solution: change the hydraulic oil and filter element as soon as possible.
The drive shaft is out of balance and vibrates violently. Therefore, the spindle swing oil seal is worn.
Solution: fix and replace the shaft in time.
Hydraulic oil will deteriorate and emulsify, reduce the lubrication performance and accelerate the wear of oil seal.
Solution: change the hydraulic oil and filter element as soon as possible. In severe cases, the system needs to be cleaned.
The pump bracket is loose, the pump is opened, and the fixing bolts of the pump are loose, which leads to the vibration of the whole hydraulic pump and the wear of the oil seal.
Solution: always check and eliminate the possibility of failure of all 2-party self loading mixer, so as to prevent and avoid failure.
The oil return pipe and radiator of the 2-party automatic mixer truck system are blocked, resulting in the pressure rise in the motor housing and oil seal leakage.
Solution: remove the blockage and stabilize the oil return circuit.
If the radiator does not dissipate heat, the temperature of the oil will become too high, the viscosity and lubricity will be reduced, the oil seal will overheat and the seal will not work.
Solution: remove the obstacles on the radiator and cool the system to prevent the pump motor from wearing. In severe cases, it is necessary to stop and stop the engine and flush the pump motor and radiator housing with water to achieve cooling effect.
During the winter operation, due to insufficient preheating and low oil temperature, the oil seal and oil seal can not reach the ideal working temperature.
Countermeasures: stop the oil tank when starting, run at idle speed for 10 to 20 minutes, and replace the oil tank when the oil temperature returns to normal
