Concrete mixer truck hydraulic system maintenance
The hydraulic system of the concrete mixer truck is a device for powering the cement mixer. It consists of a power take-off, a cardan shaft, a hydraulic pump, a hydraulic motor, a control valve, a hydraulic oil tank and a cooling device. The hydraulic system is the most stressed and worn in the mixer truck during the concrete transportation and mixing process, and it is also the most prone to failure of the concrete mixer truck.
If this part stops working due to failure, the concrete storage tank will not be able to rotate, which will cause the concrete in the vehicle to be scrapped, and even the whole tank concrete will be condensed in the tank, causing the concrete mixer truck to be scrapped. Therefore, whether the drive device is reliable or not is a problem that must be highly valued in use. In order to ensure that the hydraulic system is in good condition, the following maintenance work should be done:
a. The universal turning part is the faulty part. The grease should be filled on time, and the wear condition should be checked frequently and repaired and replaced in time. The fleet should have an alternate cardan shaft assembly to ensure that it can recover in a matter of minutes if a failure occurs.
b. Keep the hydraulic oil clean. The working environment of the concrete mixer truck is bad, and it is necessary to prevent the dirty cement sand from entering the hydraulic system. Hydraulic oil should be replaced regularly as required by the manual. Once the inspection reveals that water or sand is mixed into the hydraulic fluid, it is necessary to immediately stop the hydraulic system and replace the hydraulic oil.
c. Ensure that the hydraulic oil cooling unit is effective. It is necessary to regularly clean the hydraulic oil radiator to avoid the radiator being blocked by the cement, check whether the radiator electric fan is running normally, and prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic part ensures that the hydraulic oil is clean, there are generally few faults; however, the manufacturer has different service life.
