Description
Technical Field
The utility model belongs to the technical field of the screw pump, specifically relate to an improve from inhaling gluey double screw pump of ability.
Background
Screw pumps are rotary pumps that convey or pressurize a fluid medium by virtue of changes in volume and movement of the meshing space formed by the pump body and the screw. The screw pump has the characteristics of small volume, high efficiency and high lift, has a self-suction function, is a constant flow pump, and has the flow rate in direct proportion to the rotating speed.
The feed inlet and the export of traditional screw pump all are located the top of the pump body, and screw pump operation still has longer one section distance between working chamber and the feed inlet, because liquid is in the pipeline, and the feed inlet that is located the top needs bigger suction just can be with the liquid suction pump in the pipeline when absorbing liquid, and in low altitude area, this kind of phenomenon only needs to improve the rotational speed of screw pump in advance alright solve, nevertheless in the low area of high altitude atmospheric pressure, through improving screw pump rotational speed, also hardly overcome the condition of absorbing liquid difficulty.
