As the manufacturer of concrete mixer, it is very important to master the maintenance skills. Today, we will talk about the harm to the automatic feeding mixer truck and the maintenance skills according to the situation of oil leakage.
When starting the vehicle in winter, the preheating is insufficient, the oil temperature is too low, and the oil and oil seal do not reach the working temperature. During the whole starting process, stop the tank and idle for 10min to 20min. After the oil temperature reaches the normal state, the tank can be turned.
It has been used for a long time and the oil seal is worn normally. Replace the oil seal with a new one.
If the hydraulic oil port time is not effectively replaced, or the quality of the filter element is unqualified, the hydraulic oil is too dirty, which will speed up the oil seal wear. Replace the hydraulic oil and filter element of the automatic feeding mixer as soon as possible.
If the hydraulic oil is deteriorated and emulsified, the lubricating performance will be reduced, the oil seal wear speed shall be accelerated, and the hydraulic oil and filter element shall be replaced as soon as possible. In serious cases, the relevant systems of the automatic feeding mixer shall be cleaned.
The dynamic balance of the transmission shaft fails and the swing momentum is large, which causes eccentric wear of the oil seal of the spindle swing. Correct or replace the transmission shaft in time.
The oil return of the system is not smooth, the oil return pipe or radiator is blocked, resulting in the increase of the pressure in the pump motor housing cavity, resulting in oil seal leakage. Eliminate the blockage and ensure the smooth return oil circulation.
The radiator does not dissipate heat and causes the oil temperature to be too high, the viscosity, the lubricity to drop, the oil seal overheats, the seal loses efficacy. Timely remove the radiator failure, cooling the system as soon as possible to avoid pump motor wear. If necessary, the automatic feeding mixer should be turned off and the pump motor and radiator shell should be washed with water to achieve cooling effect.
