After each discharge, the tank truck with its own water gun shall be used to wash the tank mouth, blade, feeding mouth, tank body and corners, so as to prevent the concrete from accumulating more and more after melting. Otherwise, it is not easy to clear up. Every day after the delivery duty stops, add more than 1 cubic meter of purified water into the tank, and then the rotating tank stops cleaning. Qualified companies can also add stones in the tank, the effect will be better. Wash the tank car at any time during operation and clean it thoroughly after receiving.
Mixing truck water flow: control the air pressure, solid forbidden joint. The air pressure of the tank has been set at the time of leaving the factory, so there is no need to adjust it by yourself. In case of special circumstances, you need to adjust it by yourself. It is suggested that the air pressure be controlled at 3.5Mpa.
Due to the difference of raw materials, the concrete quality of each plate is different. When the concrete is installed, it is necessary to check its slump and workability. Be careful of the early melting of concrete and the layered precipitation of concrete, so as to avoid that the concrete can not be put into use after it is transported to the site, wasting manpower and material resources. Pay attention to the conveying distance, which may cause the change of concrete quality. The distance should be controlled within 30 km in diameter.
Plan the road and traffic situation before the mixer is out, just increase the time of vehicles on the road. In case of failure to discharge due to artificial or irresistible factors, check the condition in the tank at any time. Once it is found that the concrete begins to melt, discharge immediately to avoid scrapping of all tanks.
