Rigidity-adjustable compressor damping foot pad, compressor and control method

Abstract

The invention provides a rigidity-adjustable compressor damping foot pad, a compressor and a control method. The rigidity-adjustable compressor damping foot pad comprises a compressor damping foot pad body, wherein a mounting cavity is formed in the compressor damping foot pad body, a mounting groove is formed in the peripheral wall of the compressor damping foot pad body, and a first supporting wall is formed in the position, between the mounting groove and the mounting cavity, of the compressor damping foot pad body; and a rigidity adjusting device which comprises a first supporting plate, wherein the first supporting plate is arranged in the mounting cavity of the compressor damping foot pad body and abuts against the supporting wall so as to provide supporting force for the first supporting wall. The rigidity adjusting device can adjust the supporting force provided by the first supporting plate to the first supporting wall. The rigidity of the compressor damping foot pad can be adjusted according to the vibration characteristics of a compressor, a good damping effect can be achieved in the full frequency band of the compressor, the problem that a common compressor damping foot pad lacks horizontal vibration control is solved, and then abnormal sound of an outdoor unit and the vibration value of a pipeline are reduced.

Description

technical field [0001] The invention relates to the technical field of vibration damping devices, in particular to a compressor vibration damping pad with adjustable stiffness, a compressor and a control method. Background technique [0002] The compressor is the main vibration source of the outdoor unit of the air conditioner, and its vibration reduction work has an extremely obvious effect on the noise reduction of the outdoor unit and the vibration reduction of the pipeline. In addition to reducing the vibration of the compressor from the perspective of the compressor structure (which is more difficult), the vibration transmitted from the compressor to the outside can also be effectively attenuated through the compression-based compressor vibration-damping foot pad. [0003] At present, most of the compression-based compressor vibration damping pads used in the industry are rubber compressor vibration damping pads (EPDM rubber) with simple structures, and the compressor v...
