Compared with the centrifugal pump, the head is farther. Working principle: it has a pair of extrusion wheels that circulate to squeeze the hose, compress the hose and rotate with the roller, and the medium will generate negative pressure with the rotation of the roller to extract the medium. The extrusion pump consists of a pump body, a rotating frame, an extrusion wheel, a reducer, a reinforced hose and a drive system. The reinforced hose runs in a U shape in the pump body. When the rotating frame drives the extrusion wheel to rotate, the hose rebounds after being squeezed by the extrusion wheel, and a negative pressure is formed at the suction port to suck the slurry. The slurry is discharged from the discharge port through the pushing of the extrusion wheel, completing the power delivery of the fluid medium. The use of an extrusion pump to discharge slurry can speed up the slurry discharge speed, save slurry discharge time, and prevent the slurry discharge pipeline from being blocked by mud. Another advantage is that the head is greatly increased, and the scope of application is also greatly increased. At the same time, the extrusion pump comes with a hose, so there is no need to connect an external pipe. It can be directly retracted after use, which is convenient and quick. In order to solve the problem of mud accumulation in the pipeline, valves are installed in multiple places of the pipeline, which can be flushed with water after use to keep the inner wall of the pipeline clean. In addition, the bracket structure of this patent is stable, which not only meets the installation requirements of the slurry pump, but also ensures the installation of the traction seat.
