The service time is too long and the oil seal is normal wear. Solution: replace the oil seal.
The oil has not been replaced for a long time, the filter element quality is unqualified, and the oil is too dirty, which makes the oil seal wear faster. Solution: replace the hydraulic oil and filter element as soon as possible.
The balance of the transmission shaft fails and the swing momentum is large, which causes the eccentric wear of the main shaft swing oil seal. Solution: correct and replace the rotating shaft in time.
The deterioration and emulsification of hydraulic oil leads to the decline of lubrication performance and faster 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 pump support is loose, the pump is opened, and the pump fixing bolts are loose, resulting in the overall shaking of the hydraulic pump and the wear of the oil seal. Solution: frequently check and eliminate the possible faults in the mixer truck to prevent and avoid the occurrence of faults..
What are the methods of stopping oil in mixer truck?
The oil return of the mixer system is not smooth, and the oil return pipe and radiator are blocked, which leads to the increase of pressure in the motor shell and the oil leakage of the oil seal. Solution: remove the blockage and keep the oil return circulation unobstructed.
The radiator of the mixer truck does not dissipate heat, which leads to problems such as excessive oil temperature, decline in viscosity and lubricity, overheating of oil seal, seal failure and so on. Solution: eliminate the radiator failure and conduct the cooling process for the system to avoid the wear of the pump motor. In severe cases, stop the engine and flush the pump motor and radiator housing with water to achieve the cooling effect.
When starting in winter, if the preheating is insufficient, 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 idle for 10min to 20min when starting, and turn the tank to work after the oil temperature is normal.
The oil seal at the shaft end of the hydraulic pump of the mixer truck is a vulnerable part. If it is operated in strict accordance with the relevant specifications, in fact, many oil leakage phenomena will be better prevented. In case of oil leakage, it is necessary to calmly find out the specific causes and deal with them.
