Electromechanical coupling type oil-less vortex compression and expansion integrated machine

Abstract

The invention provides an electromechanical coupling type oil-free scroll compression and expansion integrated machine, which includes a frame, a movable scroll, a fixed scroll, a permanent magnet, a winding coil and an eccentric small shaft, and the permanent magnet is fixed inside the frame as a The stator; the winding coil is arranged outside the movable scroll as the rotor; the winding coil directly drives the movable scroll to rotate after being energized. The frame and the fixed scroll are assembled into a completely sealed assembly, the two ends of the eccentric small shaft are respectively connected with the frame and the fixed scroll, and the middle part is connected with the movable scroll. The frame, the movable scroll and the fixed scroll are all equipped with scroll teeth, and seal grooves are set on the top of the scroll teeth and the annular surfaces on both sides of the movable scroll, and the seal grooves are filled with sealing materials to realize the inner cavity. The gas is completely sealed without oil. The invention discloses an electromechanical coupling oil-free scroll compression-expansion integrated machine, which injects high-pressure special gas recovered from the outside into an expansion cavity to drive a movable scroll to rotate, realizes energy recovery, achieves oil-free sealing, and realizes special gas compression.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an electromechanical coupling oil-free scroll compression-expansion integrated machine. Background technique [0002] The existing traditional compression-expansion integrated machine, because the mechanical part and the motor part are separated, the overall size is too large. Moreover, in recent years, human beings have an increasing demand for the compression of special gases, but the special gases themselves are flammable, explosive, toxic and harmful, and the leakage of compressed gases must be avoided. However, the current all-in-one compression and expansion machine cannot meet the performance requirements of special gas compression due to poor sealing performance, and is not suitable for special gas occasions. Therefore it is very necessary to develop a small-sized, completely sealed scroll compression-expansion machine. Contents of the invention [000...

AI Technical Summary

Problems solved by technology

[0003] What the present invention aims to solve is the technical problem that the existing compression and expansion integrated machine has a large overall size and poor sealing performance, which cannot meet the requirements of special gas compression performance. It provides an electromechanical coupling oil-free scroll compression and expansion integrated machine. Integrated into the scroll and the frame, no main shaft is required, the overall size is greatly reduced, and the gas can be completely sealed to achieve special gas compression
