Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The scroll compressor is a positive displacement compression compressor, and the compression part consists of a movable scroll and a fixed scroll.

If vibration reduction is not good, vibration of the compressor can be transmitted to an installation foundation and surrounding equipment, noise pollution and equipment damage are caused, meanwhile, abrasion of a vortex main machine can be aggravated by vibration of the compressor, service life and efficiency of the compressor are reduced, even shutdown faults are caused, output is further influenced, and large loss is caused to economy.
The prior vibration damping treatment for the scroll compressor is generally to set up a first hole below the support at the bottom of the compressor and to damp vibration through an elastic mechanism, but the effect is often unsatisfactory, and the vibration damping unit is generally of an integral fixed structure, so that maintenance and replacement are difficult when faults occur, and the production cost is high.
There is no vibration reduction mechanism for scroll compressors that can solve the above-mentioned problems.
