Clean the concrete storage tank (mixing drum) and the inlet and outlet
Since concrete will solidify into a hard block in a short time and is corrosive to steel and paint, it is necessary for daily maintenance to wash the concrete adhering to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank. Serious work.
These include:
a. Rinse the feed port with water before each filling to keep the feed port moist during filling;
b. Fill the washing water tank that comes with the car with water while loading materials;
c. Rinse the feed port after loading, and clean the remaining concrete near the feed port;
d. After unloading at the construction site, flush the discharge trough and add 30-40L of cleaning water to the concrete storage tank, and keep the concrete storage tank rotating at a slow speed when the vehicle returns;
e. Remember to drain the sewage in the concrete storage tank before loading the next time;
f. Thoroughly clean the concrete storage tank and around the material inlet and outlet at the end of the day to ensure that there is no cement and concrete agglomeration.
As long as these tasks are not carried out seriously once, they will bring great troubles to future work.
Maintenance drive
The function of the driving device is to drive the rotation of the concrete storage tank. It is composed 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. If this part stops working due to a malfunction, 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 of concrete will condense in the tank, causing the concrete mixer truck to be scrapped. Therefore, whether the driving device is reliable is an issue that must be paid attention to in use.
