The function of the driving device is to drive the rotation of the concrete storage tank, which is composed of a force feeder, a universal shaft, a hydraulic pump, a hydraulic motor, a control valve, a hydraulic tank and a cooling device. If this part of the failure to stop working, the concrete storage tank will not be able to turn, which will lead to the car concrete scrap, serious even make the whole tank of concrete condense in the tank, resulting in the concrete mixing truck scrap. Therefore, whether the driving device is reliable is the problem that must be attached great importance to in use. In order to ensure the integrity and reliability of the driving device, the following maintenance work should be done:
A. The universal rotation part is the fault prone part, should be filled with grease on time, and often check the wear and tear, timely repair and replacement. The team should have a spare universal shaft assembly to ensure that in the event of a failure can be restored to work within a few minutes.
B. Ensure that the hydraulic oil is clean. Concrete mixing transport vehicle working environment is bad, must prevent sewage and sediment into the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the operation manual. Once the inspection found that the hydraulic oil mixed with water or sediment, it is necessary to immediately stop the hydraulic system cleaning, replace the hydraulic oil.
C. Ensure the efficiency of hydraulic oil cooling device. To regularly clean the hydraulic oil radiator, to avoid the radiator is blocked by cement, check the radiator electric fan operation is normal, to prevent the hydraulic oil temperature exceed the standard. Hydraulic part as long as ensure the hydraulic oil clean, general failure is few; But the manufacturer is different, the service life is different.
