Rotary compressor, sliding vane vibration system and air conditioner

Abstract

The invention discloses a slip sheet vibrating system. The slip sheet vibrating system comprises a first vibrating spring, an intermediate mass block, a second vibrating spring and a slip sheet. One end of the first vibrating spring is limited through an air cylinder or a shell. The intermediate mass block is connected with the other end of the first vibrating spring. One end of the second vibrating spring is connected with the intermediate mass block. The slip sheet is connected with the other end of the second vibrating spring. Due to the fact that the slip sheet vibrating system is a double-freedom-degree vibrating system, the double-freedom-degree vibrating system has two inherent frequencies, namely, the low-frequency inherent frequency and the high-frequency inherent frequency, the low-frequency inherent frequency and the high-frequency inherent frequency effectively avoid the working frequency band commonly used by a compressor by means of adjusting the mass of the intermediate mass block, the mass of the slip sheet, the rigidity of the first vibrating spring and the rigidity of the second vibrating spring, resonance caused by the slip sheet vibrating system can be effectively avoided, the working noise of the compressor can be lowered, and the working reliability of the compressor is improved. The invention further discloses the compressor with the slip sheet vibrating system and an air conditioner with the compressor.

Description

technical field [0001] The invention relates to the technical field of compressor preparation, in particular to a rotor compressor, a sliding vane vibration system and an air conditioner. Background technique [0002] The rotor compressor is mainly composed of a cylinder, a rolling rotor, an eccentric shaft, a sliding vane, and a motor. The cylinder is provided with a suction hole and an exhaust hole, and the rolling rotor is installed on the eccentric shaft. Driven by the motor, the rotor moves along the The inner wall of the cylinder rolls to form a crescent-shaped working chamber with the cylinder. The end of the sliding piece is in close contact with the rotor at all times by the force of the spring, which divides the crescent-shaped working chamber into two parts. The sliding piece follows the rotor The rolling motion reciprocates along the slide groove. [0003] The sliding vane and spring constitute the vibrating vane system of the compressor. With the advancement of...

Problems solved by technology

When the compressor runs at ω (ω is the motor circular frequency of the compressor), if the value of ω is close to or equal to ω n , it will cause the free vibration system to resonate, and the amplitude of the sliding vane will become larger, causing impact on the compressor rotor and generating noise; have an impact

[0004] As far as the sliding vane vibration system in the current rotor compressor is concerned, the natural frequency of the single-degree-of-freedom vibration system can be adjusted by changing the spring stiffness and the mass of the sliding vane, but it is limited by the space of the compressor and the reliability and energy efficiency ratio. , the adjustment and variation of the natural frequency of the sliding vane vibration system is very limited, and it is difficult to avoid the normal operating frequency band of the compressor
