The driving device of small concrete mixer is used to drive the rotation of concrete tank and vehicle. It is composed of power take-off, universal shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. Therefore, whether the driving device of concrete mixer is reliable or not is a problem that must be attached great importance to in use. In order to ensure the integrity and reliability of the mixer drive device, the following practice can be referred to.
The universal rotating part of the concrete mixer truck is a fault prone part, so grease should be added on time, and the wear condition should be checked regularly, and the timely repair and replacement should be carried out. The car should have spare cardan shaft assembly to ensure that once the fault occurs, it can resume work within minutes in time and ensure the hydraulic cleaning. The working environment of the concrete mixer truck is bad, so the dirty cement sand must be prevented from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the manual. Once it is found that the hydraulic oil is mixed with water or sand, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.
To ensure that the above parts of the concrete mixer truck stop working due to fault, the concrete mixing tank will not rotate, which will lead to the scrapping of the concrete in the truck, and even make the whole tank of concrete coagulate in the tank, resulting in the scrapping of the concrete mixer truck.
