Refrigeration unit and shock-absorbing foot pads for compressors

Abstract

The invention discloses a refrigerating device and a damping pad used for a compressor. A supporting piece is arranged on the compressor. The damping pad comprises a bottom column, a clamping column and a connecting column. The connecting column is arranged between the bottom column and the clamping column. The connecting column is sleeved with the supporting piece of the compressor. The supporting piece is clamped between the upper end face of the bottom column and the lower end face of the clamping column. At least part of the lower end face of the clamping column is provided with upper protruding columns. According to the damping pad provided by the invention, the supporting rigidity of the damping pad is increased in a segmental mode along with the increment of vibration displacement of the compressor, and when the amplitude of the compressor is small, the damping pad can achieve a good vibration isolation effect; and when the amplitude of the compressor is increased, strong constraint can be formed, the vibration energy is dissipated rapidly, the vibration level of the compressor in the transportation process or starting and stopping process is effectively lowered, and the amplitude and stress of compressor pipelines in the processes are effectively reduced.

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
