Chinese Concrete Pump Pumping Principle

Concrete pump pumping principle

Chinese concrete pump is driven by motor, the main pumping system adopts open oil circuit, constant power control, and has the function of hydraulic stepless speed regulation and adjusting the concrete conveying volume.

The concrete cylinder piston is connected with the piston rod of the main oil cylinder respectively. When reciprocating under the action of the hydraulic oil of the main oil cylinder, one cylinder advances while the other declines. The outlet of the soil cylinder of concrete pump made in China is connected with the hopper. One end of the distributing valve is connected with the discharge port, and the other end is connected with the swing arm through a spline shaft.

Chinese concrete pump

Chinese concrete pump in the pumping of concrete, under the action of the main oil cylinder, the concrete piston forward, the concrete piston backward, at the same time under the action of the swinging oil cylinder, the distribution valve and the concrete cylinder and the hopper connected. In this way, the concrete piston retreats, the concrete in the hopper will be sucked into the concrete cylinder, the concrete piston 7 forward, the concrete in the concrete cylinder into the distribution valve pump out.

When the piston of concrete pump made in China moves backward to the stroke terminal, the reversing device in tank 3 is triggered, the main oil cylinder changes direction, and the oil cylinder swings to change direction at the same time, so that the distributing valve is connected with the concrete cylinder 6, and the concrete cylinder 5 is connected with the hopper. At this time, the piston 7 moves backward and 8 moves forward. This cycle enables continuous pumping.

In the backpump operation, the concrete cylinder in the suction stroke is connected with the distributing valve, and the concrete cylinder in the push stroke is connected with the hopper, so that the concrete in the pipeline can be pumped back to the hopper.
