Exhaust connection structure between cylinder and shell of compressor

Abstract

The invention discloses an exhaust connection structure between a cylinder and a shell of a compressor. The exhaust connection structure comprises a cylinder cover, a cylinder cover joint, an exhaustconnecting pipe, a compressor exhaust pipe, and a compressor shell; two ends of the cylinder cover joint are separately connected with the cylinder cover and the exhaust connecting pipe, and one end which the cylinder cover joint and the exhaust connecting pipe are connected to is provided with a straight pipe section with a certain length; one end, located at the inner side of the shell of the compressor, of the compressor exhaust pipe is connected with the exhaust connecting pipe and is provided with a straight pipe section with a certain length; two ends of the exhaust connecting pipe are both provided with straight pipe sections with a certain length and the straight pipe sections are separately inserted into the straight pipe section of the cylinder cover joint and the straight pipe section of the compressor exhaust pipe; and one or more grooves are formed in the outer wall face of the matching position of the exhaust connecting pipe and the cylinder cover joint or / and the compressor exhaust pipe in an extruding mode. According to the exhaust connection structure between the cylinder and the shell of the compressor, the vibration and noise transmission of the compressor core to the outside of the compressor, thereby further reducing the vibration and noise of the whole compressor and effectively improving the sound comfort of the compressor.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to an exhaust connection structure between a compressor cylinder head and a casing. Background technique [0002] The refrigeration compressor sucks low-temperature and low-pressure gas, which becomes high-temperature and high-pressure gas after being compressed by the piston, which provides the power source for the refrigeration system. The compressed high-pressure gas in the compressor is sent to the outside of the compressor through the exhaust connecting pipe. One end of the exhaust connecting pipe is connected to the exhaust pipe on the core, and the other end is connected to the exhaust pipe on the compressor. At present, the common exhaust connection pipes of refrigeration compressors are metal pipes (seamless welded steel pipes), and the exhaust pipes on the compressor core are also made of metal materials. The compressor exhaust pipes are mostly copper pip...

AI Technical Summary

Problems solved by technology

However, due to the movement of the piston and the motor during the operation of the refrigeration compressor, the compressor core will generate greater vibration and noise, and the metal exhaust pipe connection structure can easily transmit the vibration and noise of the core to the outside of the compressor, resulting in The vibration and noise of the compressor are relatively large
