Vibration reduction structure of reciprocating compressor

Abstract

A vibration reduction structure of a reciprocating compressor comprises: a case having a suction pipe for introducing a refrigerant and a discharge pipe for discharging a refrigerant at both sides thereof; an assembly installed in the case to compress a refrigerant and composed of a cylinder, a piston, a driving unit, and a discharge valve assembly; a loop pipe installed between the discharge valve assembly and the discharge pipe with a curved shape; and a connection unit for connecting a first point of the loop pipe and a second point of the loop pipe facing the first point and thereby reducing a vibration transmission. According to this, vibration generated as the piston is operated can be transmitted to the compressor through many paths including the loop pipe and the additional connection unit. Also, generated vibration can be canceled to each other due to its phase difference, thereby preventing vibration from being transmitted to the entire case. Also, a damage of the connection part of the loop pipe due to vibration can be prevented, and a reliability of the product can be enhanced.

Description

technical field [0001] The invention relates to a shock absorbing structure of a reciprocating compressor, which can prevent the vibration generated by the assembly composed of the piston, the cylinder and the drive unit from being transmitted to the entire casing when the compressor is working, and specifically relates to such a compressor The vibration-absorbing structure can effectively reduce vibration by installing a ring pipe between the assembly and the casing and installing an additional connection unit on the ring pipe to discharge compressed refrigerant. Background technique [0002] In general, a compressor is a device for increasing pressure by receiving power from a power generating device such as a motor, a turbine, etc. to compress various gases such as air, refrigerant, and the like. Compressors are widely used in household appliances such as refrigerators and air conditioners, or in industries. [0003] Compressors can be classified into: reciprocating comp...

AI Technical Summary

Problems solved by technology

However, the elongation of the ring pipe 28 is limited

And resonance occurs in the case where the ring pipe is different from the original design due to various changes in the operating frequency of the drive unit 10 or various external influences, etc., and vibrations with large displacements are generated at specific parts of the ring pipe

The generated vibration is transmitted to the connection part of the ring pipe, so the connection part is broken, thereby reducing the reliability of the product
