Embodiment Construction

[0029] In order to better understand the purpose, structure and function of the present invention, below in conjunction with appendix Figure 1-8 , a compressor housing device and a compressor of the present invention are further described in detail.

[0030] Such as Figure 1-5 As shown, a compressor casing device is designed. This design takes the compressor as an example, and its main structure includes a casing assembly 4, a stator 2 installed in the casing assembly 4, and a rotor 3 rotatably connected to the stator 2; The housing assembly 4 is provided with a damping structure 5, which is hung on the shell wall of the housing assembly 4 in a suspended manner. When the housing assembly 4 vibrates, the damping structure 5 will move in the opposite direction of the vibration of the housing assembly 4 to offset vibrational energy. This structure is used in the compressor. When the compressor is running, the internal damping structure can be used to consume energy, reducing ...

Abstract

The invention discloses a compressor shell device. The compressor shell device comprises a shell assembly, a stator installed in the shell assembly and a rotor rotationally connected to the interior of the stator, wherein a damping structure is arranged in the shell assembly, the damping structure is hung on the shell wall of the shell assembly in a suspended manner, and when the shell assembly vibrates, the damping structure can move in the direction opposite to the vibration direction of the shell assembly to offset vibration energy. The invention further discloses a compressor. The compressor comprises the compressor shell device, wherein the bottom of an inner cavity of the shell assembly is further connected with a pump body assembly, the input end of the pump body assembly is in driving connection with the output end of the rotor, and the output end of the pump body assembly externally communicates with a liquid separator component of the compressor. Vibration of the compressor during low-frequency and high-frequency operation is reduced, and meanwhile, a damping block also serves as an oil baffle structure, so that the oil discharge rate of the compressor can be reduced, and the performance of the compressor can be improved.

Description

technical field [0001] The invention belongs to the related technical field of compressors, and in particular relates to a compressor shell device and a compressor. Background technique [0002] In the existing structure of the rotary compressor, since the rotating crankshaft has an eccentric part, the compressor vibrates relatively large during operation, especially at the upper end of the casing. The existing structure is to balance the eccentric part of the crankshaft by setting a balance weight on the rotor, but the balance weight cannot completely and effectively solve the situation of large vibration of the compressor, especially in the case of a single-cylinder compressor with large vibration at low frequency. The situation is difficult to resolve. Moreover, the vibration will cause many harms, and it will also increase the oil discharge rate of the compressor. The reduction of the internal oil volume will cause the internal parts to wear more seriously after long-te...
