Two-dimensional motor combined piston pump

Abstract

According to the two-dimensional motor combined piston pump, two two-dimensional motor piston pumps are integrated to achieve parallel output, the two-dimensional motor combined piston pump comprises a two-dimensional motor and a two-dimensional piston pump, an outer rotor of the two-dimensional motor serves as a piston and a flow distribution mechanism of the two-dimensional piston pump at the same time, and the two-dimensional motor combined piston pump rotates and axially moves in the working process. Two single pumps are integrated together to realize parallel output, so that the piston pump has a larger power-to-weight ratio; partial structures of the two-dimensional motor and the two-dimensional piston pump are shared, so that the structure is more compact; the rotor of the two-dimensional motor does not need to be supported by a bearing, so that the problem that the service life of the motor is influenced by axial force is avoided; the rotation and axial movement of the rotor are converted into magnetic coupling and decoupling by using the two-dimensional motor, so that the friction is reduced, and the efficiency is improved; the motor is of a wet-type structure, heat dissipation is good, and sparks are not prone to being caused; a two-dimensional piston pump structure is used, and the volume efficiency is high.

Description

technical field [0001] The present application relates to the fields of motor technology and fluid transmission technology, in particular to a two-dimensional motor combined piston pump composed of a two-dimensional motor and a two-dimensional piston pump. Background technique [0002] The motor is a component that converts electrical energy into mechanical energy to provide power, and is often used as a power source for pumps. An external rotor motor is one in which the coils are on the stator and the permanent magnets are on the outer rotor. Compared with ordinary motors, the rotor of a two-dimensional motor can also move axially to a certain extent while rotating. A hydraulic pump is a hydraulic component that provides pressurized liquid in a hydraulic system. It is a conversion device that converts mechanical energy such as an electric motor or an internal combustion engine into hydraulic energy. The piston pump relies on the reciprocating motion of the piston to make ...
