  The concrete trailer pump is a hydraulic double cylinder piston type pump, which is driven by an electric or diesel motor. The pump system adopts a closed oil circuit, constant power control, and concrete conveying volume adjustment.
  
  how does the concrete pump work
  (1)(2) main oil cylinder ; (3) water tank ; (4) reversing device; (5)(6) concrete cylinder; (7)(8) concrete piston; (9) hopper; (10) distribution valve; (11) swing arm; (12)(13) swing cylinder; (14) concrete outlet
  
  
  First, the concrete piston is respectively connected with the piston rod of the main oil cylinder. Under the action of the hydraulic oil of the main oil cylinder, one cylinder moves back, while the other cylinder moves forward.
  Second, the outlet of the distributing valve connects with the outlet. The other end connects with the swinging arm through a spline shaft and can swing left or right under the action of the swinging oil cylinder.
  Then, when pumping concrete materials, the concrete piston advances, the concrete piston retreats under the action of the main cylinder.
  At the same time, under the action of the swinging cylinder, the distribution valve connects with the concrete, and the concrete cylinder connects with the hopper.
  In this way, the concrete piston backward, then the concrete in the hopper into the concrete cylinder, concrete piston forward, the concrete cylinder send material into the distribution valve pump.
  When the concrete piston retreats to the end of the stroke, the reversing device in the water tank is triggered. Again, the main oil cylinder is reversed to start continuous pumping.
  The main oil cylinder changes direction simultaneously swings the oil cylinder to change direction. Then the distribution valve connects with the concrete cylinder, and the concrete cylinder outlet connects with the hopper.
  At this time, the piston retreats and goes forward, achieving continuous pumping.
  When the reverse pumping starts, in the suction process,  the distributing valve connects one concrete cylinder with the pump outlet. On the contrary, in the push process, the distributing valve will connect this concrete cylinder directly with the concrete hopper. In this way, pump will draw the concrete in the pipeline back to the hopper.
  The distribution valve is the key part of the concrete pump, and its type will directly affect the performance of the concrete pump.
