Description

Technical Field

[0001] The utility model relates to the technical field of electric compressors, in particular to a conventional refrigerant high-efficiency and low-noise electric compressor. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc.

[0003] The static scroll plate provided on the inner side of the existing electric compressor is mostly mounted on the bottom of the inner side of the protective shell by a nut. Over time, the vibration force generated by the dynamic scroll plate rotating along the static scroll plate will cause the fixed nut to loosen, thereby affecting the stability of the static scroll plate installation. The air supply pipe and the static scroll plate on the existing electric compressor are mostly fixedly connected by a nut. When the vibration force generated by the scroll plate is transmitted to the nut, it will cause the nut to loosen and fall off. At this time, the air supply pipe is easy to separate from the static scroll plate under the influence of the vibration force. Utility Model Content

When the positioning gear ring is clamped to the butt joint pipe, the protrusion on the inner surface of the positioning clamping plate fixedly connected at one end of the positioning gear ring will slide along the straight groove opened at one end of the positioning ring groove and be clamped in the positioning ring groove. Then, the clamp ring plate is rotated to drive the positioning gear ring engaged at the top to rotate, thereby driving the positioning clamping plate fixedly connected at one end of the positioning gear ring to move away from the straight groove opened at one end of the positioning ring groove. Then, the adjusted position of the positioning gear ring is fixed by a nut to prevent it from rotating again, which facilitates to improve the firmness of the butt joint between the air supply pipe and the static scroll disk, and is beneficial to prevent the vibration force generated by the compressor during use from separating the air supply pipe from the static scroll disk.
