The productivity of the concrete pump is high, and the horizontal and vertical transportation of the concrete can be completed at one time, but there are certain requirements on the mix ratio of the concrete, the particle size and gradation of the coarse and fine aggregates, the amount of cement, and the slump of the concrete, in order to ensure good pumping efficacy.
There are hydraulic transmission type and mechanical transmission type. The hydraulic transmission concrete pump is composed of hopper, hydraulic cylinder and piston, concrete cylinder, distribution valve, Y-shaped pipe, flushing equipment, hydraulic system and power system. The hydraulic system pushes the piston back and forth through pressure. When the piston moves backward, it sucks the material, and when the concrete delivery pump is pushed forward, it presses the concrete in the concrete cylinder into the delivery pipe through the Y-shaped tube. After pumping the concrete, clean the pump body and delivery pipe with high-pressure water or compressed air. The displacement of the piston concrete pump depends on the number and diameter of the concrete cylinder, the reciprocating speed of the piston and the volumetric efficiency of the concrete cylinder suction.
