Small-sized high-pressure plunger high-pressure water pump based on two-degree-of-freedom motor

Abstract

The invention discloses a high-pressure plunger two-dimensional (2D) water pump based on a two-degree-of-freedom motor control type. The high-pressure water pump comprises a two-degree-of-freedom motor providing power and a water pump, wherein the water pump comprises a rotor pump core, a pump shell, an end cover and a two-degree-of-freedom (rotation and axial direction) movement mechanism. The high-pressure water pump has the beneficial effects that the pump core and a plunger are designed to be integrated, self-balancing flow is directly realized by means of rotation and sliding of the pumpcore, when the pump core rotates by one circle, a piston reciprocates twice, and water is sucked and discharged four times; when rectangular grooves in the piston communicate correspondingly with water suction holes and water discharge holes periodically, the volume of a cavity communicating with the water suction holes is gradually increased, so that water suction is carried out, and the volume of a cavity communicating with the discharge holes is gradually reduced, so that water discharge is carried out; and miniaturization is realized, and the cost is reduced on the premise that pressure and flow are ensured.

Description

technical field [0001] The invention relates to a plunger type water pump, in particular to a small high-pressure plunger high-pressure water pump based on a double-degree-of-freedom motor. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. [0003] According to different working principles, water pumps can be divided into positive displacement pumps, centrifugal pumps and other types. Positive displacement pumps use the change of their working volume to transfer energy, and there are types such as plunger pumps, gear pumps and worm pumps; centrifugal pumps use the interaction between rotati...

AI Technical Summary

Problems solved by technology

Ordinary vane pumps use the motor to drive the shaft and impeller to achieve the function of drainage, so the pump body of ordinary vane pumps cannot generate ideal pressure

Traditional positive displacement water pumps rely on volume changes to periodically absorb and discharge liquids over and over again. Because of structural defects, gear pumps and worm pumps are difficult to make into high-pressure water pumps.

Although the plunger pump can be made into a high-pressure water pump, the structure of the traditional plunger water pump is complicated and it is difficult to realize miniaturization
