How to distinguish the pump category?
A According to working principle
1. Positive displacement pump
The working volume is periodically increased and reduced by the movement of the working parts to suck and discharge the liquid, and the pressure energy of the liquid is directly increased by the squeezing of the working parts. According to the different movement modes of the moving parts, it is divided into two types: reciprocating pump and rotary pump. According to the structure of the moving parts, there are piston pumps and plunger pumps, gear pumps, screw pumps, vane pumps and water ring pumps.
2. Impeller type pump
The impeller type pump relies on the impeller to drive the liquid to rotate at a high speed and transfer the mechanical energy to the conveyed liquid. According to the structural characteristics of the impeller and flow channel of the pump, different impeller types can be divided into:
1) Centrifugal pump
2) Axial pump
3) Mixed-flow pump
4) Peripheral pump
3. The jet pump is a high-speed jet produced by the working fluid to eject the fluid, and then through the momentum exchange to increase the energy of the ejected fluid.
Other classification of B pump
The pump can also be divided into:
1) Vertical pump
2) Horizontal pump
Divided by the number of suction ports:
1) Single suction pump
2) Double suction pump
According to the prime mover driving the pump:
1) Motor pump
2) Gas turbine pump
3) Diesel pump
4) Pneumatic diaphragm pump (diaphragm pump)
