What are the types of pumps? Such as screw type, plunger type, gear type, leaf wheel type, etc., is the vane pump the impeller type?
Other questions have already been answered by others, and I will answer your last question. Pumps with vanes are not bladed. The impeller and blade.
Not counting! First of all, you must know why the impeller pump is called impeller pump That is to say, the liquid is pumped by the impeller instead of other functions!
According to the principle of division1. displacement pumpDepending on the movement of the work parts, the volume of the work is periodically increased and reduced, while the liquid is sucked and discharged, and the pressure of the liquid is increased directly by the extrusion of the working parts.According to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pump.According to the structure of the moving parts are different: piston pump and piston pump, there are gear pumps, screw pumps, vane pumps and water ring pump.2. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed, and the mechanical energy can be transferred to the liquid conveyed.According to the impeller and runner structure features of the pump, the impeller can be divided into: 1) centrifugal pump (centrifugal, pump)
