Concrete Pump Machine
Working Process of Concrete Pump Machine:
First of all, the concrete pump must be parked on flat, solid ground, absolutely not on soft ground, in order to avoid the inclination in the process of work. Start the main motor for a short time operation, and observe whether the pressure gauge is normal. According to the length of the pipeline, before starting the construction work, we must first pump the water into the pipeline through the pendulum valve to lubricate the pipe wall. Then mortar, and finally concrete, work begins, and often run the test pump empty, with clear water pumping to confirm the smooth pipeline.

Structure and working principle of concrete pump machine:
concrete pump is mainly consists of concrete pumping system, hydraulic electromagnetic commutation mechanism, PLC integrated electrical automatic control system, discrete system, lubrication system, hopper, pump frame and so on (see Fig. 1 for details). PLC controller and inductance proximity switch are used to control hydraulic components such as electromagnetic commutation valve, oil cylinder and swing cylinder. Finally, the S-tube swing valve is opened and closed regularly with the pumping system such as piston and material cylinder, so as to continuously suck and discharge slurry.
