Agitator building should be used in concrete mixing plant and other concrete mechanical engineering construction. Aggregate concrete mixing plant measurement compared with aggregate concrete mixing station measurement, reduced the four of the intermediate links, and the vertical blanking metering, saved measuring time, thus greatly improving the production efficiency. Under the same model, the production efficiency of mixing building is one third higher than that of concrete mixing plant.

The function of solenoid valve is to adjust the pressure, flow and flow direction of compressed air. Electromagnetic valves can be used to form a variety of air routes to enable the pneumatic actuator to work in accordance with the designed procedures. The common fault of solenoid valve is air leakage, which shows that the solenoid valve has air leakage at two outlets on one side of the inlet when it is not working (the air pressure is within the standard range). The repair method is to disassemble the solenoid valve, clean the parts with clean diesel oil, dry them with clean cotton yarn and apply a small amount of oil to the surface. If the piston rod in the valve is badly worn or the sealing ring is damaged, new parts should be replaced.ws.
