Reciprocating pump, rotor pump, screw pump what is the difference
Rotor pump pressure head is high, the flow is usually small, uniform drainage, suitable for conveying high viscosity, with lubrication, but does not contain solid particles of liquid.
Consists of a stationary pump housing and a rotating rotor which does not have a suction valve and a discharge valve which acts directly on the liquid in the form of a static pressure by the side of the rotor in contact with the liquid in the pump and discharged by the rotation of the rotary rotor
Liquid, while leaving the other side of the space, the formation of low pressure, so that the liquid continuous inchalation.
The rotor pump is assembled with the overall coupling to reduce the power consumption of the flexible coupling, noise and wear and replace the work efficiency, the highest efficiency, the smallest internal sliding and longer service life.
Type gear pump, screw pump, vane pump, flexible impeller pump, Roots pump, rotary piston pump, etc., in which gear oil and screw pump is the most common rotor pump.
