Maintenance and upkeep of hydraulic system for concrete self loading mixer truck
The maintenance and upkeep of the hydraulic system of the concrete self loading mixer truck is an important part to ensure its stable operation and extend its service life. Here are some key maintenance and upkeep suggestions.

1、 Regularly check hydraulic oil

• Hydraulic oil quality

Hydraulic oil is an important medium in hydraulic systems, and its quality directly affects the performance of the system. Ensure that the hydraulic oil is clean and free of impurities, and avoid mixing hydraulic oil of different brands or models.

• Hydraulic oil replacement

Regularly replace hydraulic oil according to the requirements of the user manual. Usually, after a period of use (such as 100 days or 500 hours), the hydraulic oil of a new car should be replaced, and then it should be replaced according to the prescribed cycle (such as 2000 hours or annually).
Hydraulic oil filtration: When refueling or changing oil, an oil filter should be used for filtration to prevent impurities from entering the hydraulic system. At the same time, regularly inspect and clean the oil filter to ensure its normal operation.

2、 Keep the hydraulic system clean and sealed

• Cleaning hydraulic system

Regularly clean the dust and debris around the hydraulic system to prevent them from entering the interior of the hydraulic system.
Check sealing: Regularly inspect the sealing condition of the hydraulic system, including oil connections, seals, etc., to ensure that they are tight and leak free. If a leak is found, it should be dealt with promptly.

3、 Inspect and maintain hydraulic components

• Hydraulic pump and hydraulic motor

Maintain the hydraulic pump and hydraulic motor according to the requirements of the product manual. Regularly check its working status to ensure its normal operation.

• Valve components

Check the wear and blockage of valve components such as control valves and check valves, and promptly clean or replace damaged components.

• Radiators

Regularly check the heat dissipation effect of the radiator, clean the dust and debris on the surface of the radiator blades, and ensure normal heat dissipation.

4、 Pay attention to the working temperature of the hydraulic system
The working temperature of hydraulic systems should generally be within the range of 30~70 ℃, with a maximum not exceeding 80 ℃. Excessive or insufficient temperature can affect the performance and service life of hydraulic systems. Therefore, the cooling device of the hydraulic system should be checked regularly to ensure its normal operation.

5、 Other maintenance measures

• Regularly tighten bolts

Regularly inspect and tighten the bolt connections in the hydraulic system to prevent leaks or malfunctions caused by looseness.

• Maintain lubrication of the idler and raceway

Regularly inject lubricating grease into the idler and raceway to maintain their good lubrication condition and reduce wear and failure.

• Check the mixing drum

After each use, the inside and outside of the mixing drum should be thoroughly cleaned to prevent concrete clumping and corrosion. At the same time, check the wear of the mixing blades and promptly repair or replace damaged blades.
