Problems solved by technology

On the other hand, moreover, during the operation of the orbiting scroll 30b, the back pressure force on the side covering the groove is less than that on the opposite side, that is, the force on both ends of the end plate of the orbiting scroll 30b The situation is not consistent. The result is that the end plate of the orbiting scroll 30b is prone to overturning during operation, resulting in a decrease in the sealing performance of the orbiting scroll 30b and a deterioration in the performance of the compressor. Wear between the spiral wrap and the fixed scroll 30a ultimately affects the performance and life of the compressor

Embodiment Construction

[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Such as Image 6As shown, the scroll compressor is mainly composed of a closed casing 1 , a gas compression assembly 3 and a motor drive assembly 4 . The gas compression assembly 3 includes a fixed scroll 3a and an orbiting scroll 3b, which are located on the upper part of the sealed casing 1; the motor drive assembly 4 includes a stator 4a and a rotor 4b, which are installed in the middle of the sealed casing 1, and the sealed casing 1 T...

Abstract

The invention provides a scroll compressor. The scroll compressor is characterized in that an end plate of a fixed scroll piece is provided with an annular groove which is formed by a groove and an oil film seal groove which are connected, the movement range of the end plate periphery of the rotating scroll piece is always in the annular groove, and the end plate of the rotating scroll piece does not generate friction with any periphery of the annular groove; the groove is deep and narrow, the stress of each part of the fixed scroll piece is basically uniform, in addition, an oil film sealing layer is formed between the two scroll pieces through an oil film seal groove, therefore, the suction force of the scroll pieces is increased, and an overturning phenomenon is prevented.

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] Compared with other compressors, scroll compressors are widely used in household and commercial refrigeration and air conditioners due to their advantages of high efficiency, high reliability and quietness. In this type of scroll compressor, the surface of the fixed scroll opposite to the end plate of the orbiting scroll is usually provided with a substantially annular sealing portion, and has an annular recess connected to the outer side of the annular sealing portion. groove. [0003] Such as figure 1 As shown, the fixed scroll 30a of the scroll compressor of the prior art 1 has a scroll 140, and the outer circumferential direction of the scroll 140 has a basic gap formed by the end plate of the fixed scroll 30a and the end plate of the orbiting scroll. An annular sealing portion 300 and an annular groove 320 . A back pressure regulating valve 150 is provided near...
