The service time is too long and the oil seal is normally worn. Solution: replace with a new oil seal.
The oil has not been replaced for a long time, the quality of the filter element is unqualified, and the oil is too dirty, which speeds up the wear of the oil seal. Solution: replace the hydraulic oil and filter element as soon as possible.
The balance failure of the transmission shaft and the large swing caused the eccentric wear of the main shaft swing oil seal. Treatment plan: correct and replace the rotating shaft in time.
The deterioration and emulsification of hydraulic oil lead to the decline of lubrication performance and accelerate the wear of oil seal. Solution: replace the hydraulic oil and filter element as soon as possible, and clean the system when it is serious.
The looseness of pump bracket, pump opening and pump fixing bolts lead to the overall shaking of hydraulic pump and the wear of oil seal. Solution: often check and eliminate the possible faults in the automatic feeding mixer, prevent and avoid the occurrence of faults.
The oil return of the automatic feeding mixer system is not smooth, and the oil return pipe and radiator are blocked, which leads to the increase of pressure in the motor housing and oil leakage of the oil seal. Solution: remove the blockage and keep the return oil circulation unobstructed.
The radiator does not dissipate heat, resulting in high oil temperature, viscosity, lubricity decline, oil seal overheating, seal failure and other problems. Solution: remove the radiator fault, cooling the system to avoid pump motor wear. In serious cases, the engine should be shut down and the pump motor and radiator shell should be flushed with water to achieve cooling effect.
In winter, if the preheating is not enough, the oil temperature is too low, and the oil and oil seal do not reach the ideal working temperature. Treatment scheme: stop the tank and run at idle speed for 10min to 20min when starting, and then turn the tank to work after the oil temperature is normal.
The oil seal of the hydraulic pump shaft end of the automatic feeding mixer is a vulnerable part. If it is operated in strict accordance with the relevant specifications, in fact, many oil leakage phenomena will be effectively prevented. If there is an oil leakage problem, it is necessary to calmly find out the specific reasons and deal with it.
