BOG compressor case with vibration-reducing and sound-proof functions

Abstract

The invention discloses a BOG compressor case with the vibration-reducing and sound-proof functions. The BOG compressor case comprises a case body; a sound-proof cotton layer is fixedly connected to the inner wall of the case body; a round hole is formed in the upper surface of the case body; a heat dissipation fan is fixedly connected to the inner wall of the round hole; sound attenuation holes are formed in the surfaces of both the case body and the sound-proof cotton layer; a first base is fixedly connected to the lower surface of the case body; and an inwards-concaved cavity is arranged onthe surface of the first base. By means of the BOG compressor case with the vibration-reducing and sound-proof functions, effective treatment and sound-proof treatment can be performed on noise generated during operation of a BOG compressor, and a good working environment can be created for workers; and vibration generated during operation of the BOG compressor can be reduced, the vibration is effectively reduced by being transmitted to first hydraulic rods, a second hydraulic rod and springs, and the noise caused by the vibration is lowered, so that the problems that noise pollution is caused by severe vibration of the BOG compressor, consequently the working environment of the workers is affected and the health of the workers is harmed are effectively solved.

Description

technical field [0001] The invention relates to the technical field of BOG, in particular to a BOG compressor box with shock absorption and sound insulation. Background technique [0002] BOG compressor is the core component of the system, and its working quality directly affects the operation of the entire system. The general working pressure of BOG compressors working on LNG tankers is 0.4 to 6.4Mpa. Parts in contact with low temperature gas must use corresponding low temperature materials, and the system must also be equipped with a temperature controller. At the same time, from the consideration of operating economy, the cooling capacity per unit volume of the BOG compressor is required to be large, the compression ratio should be low, and it can ensure the reliable operation of all parts at low temperature. In order to prevent gas leakage at low temperature, the shaft of the BOG compressor The sealing performance is better. [0003] At present, ordinary BOG compressor...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a BOG compressor box with shock absorption and sound insulation, which solves the problem of noise pollution caused by the large vibration of the BOG compressor, which affects the working environment of the staff and endangers the health of the staff
