Background
The working principle of a pump commonly used by the current production enterprises is as follows: the impeller is driven by the pump shaft to rotate, works on fluid between the blades, and the fluid is thrown to the periphery from the center of the impeller under the centrifugal action. When the fluid reaches the outer periphery of the impeller, the flow rate is very high. The pump shell collects the liquid thrown out from the blades, and the liquid flows in the pump shell along the volute channel in the gradually expanding direction, so that the kinetic energy of the fluid is converted into static pressure energy; the process presupposes that the liquid must be allowed to flow in the vicinity of the pump impeller; since the liquid tank contains a large amount of corrosive chemical substances, holes cannot be formed or are inconvenient for safety, and an immersed pump cannot be placed in the liquid tank for a long time, the I can only use an aboveground pump; the ground is difficult to suck the liquid in the liquid tank into the pump shell by the ground pump because the ground has larger height drop from the liquid level in the liquid tank.
