Abstract

The invention relates to an infinitely variable speed liquid conveying pump, in particular to liquid conveying, and belongs to the field of liquid conveying pumps. The infinitely variable speed liquid conveying pump comprises a pump body, a motor, a first shaft coupling, a second shaft coupling, a first bearing seat, a second bearing seat, a revolving shaft, an impeller pressurizing barrel, an infinitely variable speed box and vanes, wherein a plurality of upright vanes are distributed symmetrically on an impeller; the revolving shaft is connected with an input shaft of an infinitely variable speed case through the first shaft coupling; and an output shaft of the infinitely variable speed case is connected with the motor through the second shaft coupling. The infinitely variable speed liquid conveying pump is simple, compact and reasonable in structure; infinitely variable speed can be realized, and the requirements of liquid conveying under different situations are met; the infinitely variable speed liquid conveying pump is resistant to corrosion, wear, high temperature and high pressure, and has high mechanical sealing property; and the infinitely variable speed liquid conveying pump has low failure rate and long service life.

Description

technical field [0001] The invention relates to a continuously variable liquid conveying pump, in particular it is used for liquid conveying and belongs to the field of liquid conveying pumps. Background technique [0002] A liquid delivery pump is a machine that converts the mechanical energy of a motor into liquid energy. The pump is used to increase the potential energy, pressure energy and kinetic energy of the liquid. The motor drives the impeller to rotate through the pump shaft, and works on the liquid to increase its energy, so that the required amount of liquid is transported from the suction pool to the required high place or place with required pressure through the flow-passing parts of the pump. [0003] The pumps used in the field of liquid transportation can be roughly divided into: centrifugal pumps, magnetic pumps, mixed flow pumps, gear pumps, screw pumps, vane pumps, booster pumps, high pressure pumps and screw pumps. The liquid delivery pump is mainly dr...
