If used for a long time, the oil seal will wear. 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 wear of the oil seal will be faster. Solution: replace the hydraulic oil and filter element as soon as possible.
The drive shaft is unbalanced and vibrates violently, resulting in the wear of the main shaft swing oil seal. Solution: fix and replace the shaft in time.
The hydraulic oil will deteriorate and emulsify, reduce the lubrication performance and accelerate the wear of the oil seal. Solution: replace the hydraulic oil and filter element as soon as possible. In severe cases, the system needs to be cleaned.
The pump support is loose, the pump is opened, and the pump fixing bolts are loose, resulting in vibration of the whole hydraulic pump and wear of the oil seal. Solution: always check and eliminate the possibility of failure of fully automatic feeding and mixing forklift to prevent and avoid failure.
The oil return of the automatic refueling / hybrid integrated vehicle system is not smooth, and the oil return pipe and radiator are blocked, resulting in increased pressure 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 oil temperature will become too high, the viscosity and lubricity will be reduced, the oil seal will overheat and the seal will not work.
Solution: remove obstacles from the radiator and cool the system to prevent wear of the pump motor. 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 winter operation, due to insufficient preheating and low oil temperature, the oil seal and oil seal cannot 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.
