Problems solved by technology

However, this contradictory design requirement makes it difficult for the traditional exhaust mechanism to take into account the energy efficiency improvement requirements of high and low frequency working conditions, that is, if the low frequency energy efficiency is improved, the high frequency energy efficiency will be sacrificed, and vice versa
In addition, the exhaust mechanism has chattering noises and knocking noises on the lift limit during operation

Abstract

The invention discloses a rotary compressor and a bearing component thereof. The bearing component comprises a bearing, a discharge valve plate, a lift limiter and an elastic piece, wherein an exhaust port is formed in the bearing, one end of the discharge valve plate is connected with the bearing, and the other end of the discharge valve plate covers the exhaust port; the lift limiter is arranged on the one side, away from the exhaust port, of the discharge valve plate, the elastic piece is arranged between the discharge valve plate and the lift limiter, and the part, corresponding to the exhaust port, of the elastic piece and the discharge valve plate are separated from each other. According to the bearing component, the bearing component is simple in structure. When the bearing component is applied in the rotary compressor, the falling back speed of the discharge valve plate is quickened under high-frequency revolving condition, the backflow of refrigerant gas is decreased, on the premise that the low-frequency energy efficiency of the rotary compressor is not lowered, the high-frequency energy efficiency is improved, the tremor of the discharge valve plate and the impact velocity of the discharge valve piece for the lift limiter are decreased by virtue of the bearing component, so that the running noise of the rotary compressor is lowered.

Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a rotary compressor and a bearing assembly thereof. Background technique [0002] It is pointed out in the related art that in the exhaust mechanism of the rotary compressor, the stiffness of the exhaust mechanism has a great influence on the energy efficiency of the rotary compressor. When the rotary compressor operates under low frequency conditions, it is desirable that the exhaust mechanism has a smaller stiffness to reduce exhaust resistance; when it operates under high frequency conditions, it is desired to improve the exhaust mechanism to a certain extent Rigidity to reduce refrigerant gas backflow to improve energy efficiency. However, this contradictory design requirement makes it difficult for the traditional exhaust mechanism to take into account the energy efficiency improvement requirements of high and low frequency working conditions, that is, if t...
