Pump classification according to the principle of action: what kind of machine can be called a pump? Usually raise the liquid, the liquid delivery and increase the liquid pressure of the machine collectively referred to as the pump. The purpose of the pump can be divided into the following three categories according to the principle of action: 1. The volume pump uses the change of the kitchen volume to feed the liquid, such as piston pump, plunger pump, diaphragm pump, gear Pumps, skateboard pumps, screw pumps, etc. 2. Vane pumps utilize the interaction of vanes and liquids to transport liquids such as centrifugal pumps, mixed flow pumps, axial flow pumps, vortex pumps, etc. 3. Other types of pumps include those that only change the liquid potential Of the pump, such as waterwheel, the use of fluid energy to transport liquid pumps, such as jet pump, water hammer pump, sour egg, etc .. The use of various types of pumps is different, the largest area occupied by the centrifugal pump flow of 5 ~ 20000 m. /, The head in the range of 8 ~ 2800 meters, the use of centrifugal pump is more appropriate because in this performance range, centrifugal pump with high speed, small size, light weight, high efficiency, large flow, Knot dig simple, stable performance, easy operation and maintenance, etc. Domestic and foreign production practices show that the output value of centrifugal pumps in pump products is the highest.
