Exhaust pipe structure of compressor

Abstract

The invention discloses an exhaust pipe structure of a compressor. The compressor comprises a case, wherein the case consists of a tube body, an upper cover, a lower cover and the like, a motor and a compressor assembly are arranged in the case, the motor consists of a stator, a rotor, a crank shaft and the like, the compressor assembly consists of a gas cylinder, an upper part bearing, a lower part bearing and the like, an exhaust pipe is arranged on the upper cover and is inserted into the case of the compressor, a rectangular groove or an arch groove is formed on the pipe wall of the lower end of the exhaust pipe, in addition, a rectangular bending part or an arch bending part is formed. Because the rectangular bending part or the arch bending part is formed on the pipe wall of the lower end of the exhaust pipe of the invention, lubricating oil is prevented from flowing out, and the refrigeration capability of the compressor is improved.

Description

technical field [0001] The invention belongs to a compressor, and in particular relates to a rectangular groove or an arcuate groove formed on the wall of the lower end of the exhaust pipe, and a rectangular or arcuate bending portion is formed to prevent the outflow of lubricating oil so as to improve the efficiency of the motor Compressor discharge pipe structure. Background technique [0002] Such as figure 1 As shown, the compressor in the prior art includes a motor 20 installed on the inner upper side of the housing 1 , and a compressor assembly 30 installed at a certain distance on the lower side of the motor 20 . The casing 1 is composed of a hollow cylindrical body 11 , an upper cover 12 , a lower cover 13 and the like. The motor 20 is press-fitted and fixed on the inner peripheral surface of the cylinder 11, and it is composed of a stator 21, a rotor 22, and a rotating crankshaft 23 that is press-fitted and fixed at the center of the rotor 22 and transmits rotatio...

AI Technical Summary

Problems solved by technology

However, since the exhaust pipe 50 is a smooth cylinder without obstruction, the high-pressure refrigerant gas can easily take away part of the lubricating oil and discharge it through the exhaust pipe, resulting in loss of lubricating oil.

[0006] As the lubricating oil increases with the discharge of high-pressure refrigerant gas, the loss of lubricating oil is accelerated, which is not conducive to the operation of the compressor, and also reduces the refrigeration capacity of the compressor
