Double-butterfly coordinated distribution pump driven by linear resonant motor

Abstract

The invention provides a double-butterfly-shaped cooperation flow distribution pump driven by linear resonance motors. The double-butterfly-shaped cooperation flow distribution pump comprises at least one pump unit. Each pump unit comprises two pump modules which are in oil path connection through a double-butterfly-shaped flow distribution valve block. The pump modules comprise the linear resonance motors, and springs are arranged inside rotors of the linear resonance motors. The linear resonance motors drive plungers and are then used in cooperation with the oil path of the double-butterfly-shaped flow distribution valve block, so that flow pumping is achieved. The double-butterfly-shaped cooperation flow distribution pump driven by the linear resonance motors has high dynamic regulation capacity; meanwhile, the rotors and the springs are used in cooperation with each other to form a mass-spring resonance system, so that winding current in deceleration of the rotors of the motors is reduced, and the overall efficiency of the integrated pump is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pumps, in particular to a double-butterfly coordinated distribution pump driven by a linear resonant motor. Background technique [0002] At present, many research objects in the engineering field are highly complex systems, and most of these systems involve theories of many disciplines. Therefore, multidisciplinary integrated design and optimization is one of the important directions in the field of modern technology. For the hydraulic system, the hydraulic pump receives the torque input from the outside and outputs the flow and pressure through the hydraulic transmission medium. It is the component that completes the conversion of mechanical energy to hydraulic energy in the hydraulic system. pump etc. The above-mentioned traditional hydraulic pumps are mainly used in open hydraulic systems. Its characteristic is that regardless of the demand of the load, the pump and the motor unit have been...

AI Technical Summary

Problems solved by technology

Its defect is that the rotary motion of the plunger on the revolution circle needs to be converted into reciprocating motion through a complex mechanism, which results in many internal transmission links and friction pairs of the plunger pump.

For the application requirements of the pump-controlled hydraulic system, the plunger pump needs to change the direction of rotation of the rotating parts to change the flow direction of the oil, or dynamically adjust the inclination of the swash plate to change the flow direction of the oil. The complexity of the structure causes the moment of inertia of the rotating parts Large, so its ability to dynamically adjust the system flow and pressure is limited, which cannot meet the high dynamic requirements of the pump control system
