Refrigeration device and damping foot pad for compressor

Abstract

The invention discloses a refrigeration device and a damping foot pad for a compressor. The refrigeration device comprises a box body bottom plate, the compressor and the damping foot pad; a supporting part is arranged on the compressor; the damping foot pad comprises a bottom column, a clamping column and a connecting column; and the bottom column is connected with the box body bottom plate, the connecting column is arranged between the bottom column and the clamping column, the connecting column is sleeved with the supporting part of the compressor, in the at least part of area of the lower end face of the clamping column, the distance between the portion close to the periphery and the supporting part is s1, the distance between the portion close to the central axis and the supporting part is s2, and s1 is large than s2. According to the refrigeration device, when the vibration amplitude of the compressor is small, supporting rigidity of the damping foot pad is small, the vibration isolation effect can be exerted, the outward vibration transmissibility of the compressor is reduced, and outer box vibration and noise radiation are restrained; and when the vibration amplitude of the compressor is increased, supporting rigidity of the damping foot pad becomes large, vibration energy is rapidly dissipated, large vibration of the compressor and a pipeline is restrained, and the pipeline breaking phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration device and a shock-absorbing pad for a compressor. Background technique [0002] The compressor is the core component in the air conditioning and refrigeration system, and it is also the main source of vibration in this system. During the operation of the compressor, there will be relatively severe vibration excitation, which will stimulate the structural vibration of the shell chassis and even the entire system, resulting in high noise and damage to the structure of the refrigeration system. [0003] In order to solve this problem, the general method is to add a vibration damping structure between the compressor and the shell chassis, and reduce the vibration excitation transmitted from the compressor to the shell chassis by means of vibration isolation, thereby reducing the noise level of the entire system and vibration response. [0004] However, the me...

Problems solved by technology

[0004] However, the means of vibration isolation will also create some new problems.

For example, during transportation, if the energy excited by the external transportation falls within the frequency range of the compressor vibration-damping structure and the compressor combined system, the system composed of the compressor and the vibration-damping structure is prone to resonance, which will lead to Larger vibration occurs in the compressor pipeline and four-way valve, which may cause structural damage or even breakage of the compressor pipeline during transportation

Another example is that during the operation process, the pulse excitation generated by the start and stop of the compressor will inevitably stimulate the large vibration of the compressor damping structure and the compressor combined system, which will lead to large start-stop stress and fatigue damage of the compressor pipeline , with the accumulation of use time, the compressor pipeline may also be broken
