What should I do if the shovel automatic feeding concrete mixer truck leaks oil?
When starting the car in winter, the oil temperature will be too low due to insufficient preheating. When the oil and oil seal have not reached the working temperature, the shovel automatic feeding concrete mixer needs to stop the tank and run at an idle speed for 10 to 20 minutes during the whole starting process. After the oil temperature reaches the normal state, the tank transfer work will be started.
If the use time is too long, the oil seal needs to be replaced under the condition of normal wear and tear.
If the hydraulic cylinder has not been effectively replaced, or the quality of the filter element is unqualified, the hydraulic oil is too dirty, which will speed up the wear rate of the oil seal. Replace the hydraulic oil and filter element of the shovel automatic feeding concrete mixer truck as soon as possible.
The hydraulic oil is deteriorated and emulsified, the lubricating performance is reduced, the oil seal wear speed is accelerated, the hydraulic oil and filter element should be replaced as soon as possible, and in severe cases, the related systems of the shovel automatic feeding concrete mixer should be cleaned.
The dynamic balance of the drive shaft fails, and the swing amount is large, causing eccentric wear of the main shaft swing oil seal. Correct or replace the drive shaft in time.
The oil return of the system is not smooth, and the oil return pipe or the radiator is blocked, which causes the pressure of the pump motor casing cavity to increase, causing the oil seal to leak oil. Eliminate blockages and ensure smooth oil return circulation.
The radiator does not dissipate heat, causing the oil temperature to be too high, the viscosity and lubricity to decrease, and the oil seal to overheat and seal to fail. Eliminate the fault of the radiator in time, cool the system as soon as possible, and avoid the wear and tear of the pump motor. If necessary, the automatic feeding mixer should be turned off, and the pump motor and radiator housing should be washed with water to achieve the cooling effect.
