The types of pumps are divided into household and industrial. Here we mainly introduce the types of industrial pumps.
According to different working principles:
(1) Centrifugal pump
How the centrifugal pump works
Before the pump starts, the pump and the inlet pipe are filled with water. After the pump is running, under the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller flow channel is pushed to the periphery, pressed into the volute, and the impeller inlet forms a vacuum. The water in the pool is inhaled along the suction pipe under external atmospheric pressure to supplement this space. The water that is inhaled is then pumped out of the volute by the impeller into the outlet pipe. It can be seen that if the centrifugal pump impeller rotates continuously, it can continuously absorb water and press water, and the water can be continuously raised from a low place to a high place or a distant place. In summary, the centrifugal pump is called the centrifugal pump because the centrifugal force generated by the high-speed rotation of the impeller raises the water to a high position.
(2) Axial flow pump
How axial flow pump works
The axial flow pump and the centrifugal pump work differently, and it mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. The lift generated by the axial pump when it rotates can push the water from below to the top.
The blades of the axial flow pump are typically submerged in a pool of water source. Due to the high-speed rotation of the impeller, under the lifting force generated by the blade, the water is continuously pushed upward, so that the water flows out along the outlet pipe. As the impeller rotates continuously, the water is continuously pressed to a high place.
(3) Mixed flow pump
How the mixed flow pump works
Since the shape of the impeller of the mixed flow pump is between the centrifugal pump impeller and the axial flow pump impeller, the working principle of the mixed flow pump has both centrifugal force and lift. By the combined action of the two, the water flows out of the impeller at a certain angle with the shaft. Lift the water up through the volute chamber and piping.
