Hydraulic concrete pump from the hopper

There are hydraulic and mechanical drive type. Hydraulic concrete pump from the hopper, hydraulic cylinder and piston, concrete tanks, dispensing valve, Y-shaped tube, washing equipment, Precast concrete plant and power systems and other components. The hydraulic system by the pressure pushes the piston reciprocating motion. When the suction piston backward, forward and backward through the Y-shaped tube when the concrete pressed into concrete cylinder pipes. After pumping concrete, or compressed air cleaning with high pressure water pump and pipes. Concrete pump piston displacement, depending on the number and diameter of the concrete cylinders, ready mix concrete plant velocity and concrete cylinder sucked volumetric efficiency. Diaphragm in the pump body, when the pump below the water through the diaphragm control valve withdrew tanks, the diaphragm subsidence, concrete hopper pressure to open the check valve into the pump; when the pump in the tank of water through the pump control valve withdraw When the diaphragm pressure water rises, closing check valve, pressed into the concrete drain pipes.
