Problems solved by technology

In addition, for some low-voltage compressors with large motor wire diameters, the effect of oil separation is poor, and the refrigerant gas compressed by the compressor contains more refrigeration oil, which will further increase the oil output of the compressor

Embodiment Construction

[0036] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] Such as figure 1 As shown, the rotor assembly 11 according to the embodiment of the present invention includes a rotor body 113 , a balance weight 111 , an enclosure 112 and a fan 115 . The balance weight 111 , the enclosure 112 and the fan 115 are all arranged on the rotor main body 113 . The fan 115, the rotor main body 113, and the balance weight 111 are along the first direction (such as figure 1 The left-to-right direction) are arranged in sequence.

[0038] The rotor main body 113 is provided with a plurality of ventilation holes 1131 , and the plurality of ventilation holes 1131 extend along the axial direction of the rotor main body 113 to penet...

Abstract

The invention discloses a rotor assembly, a motor and a compressor, the rotor assembly comprises a rotor main body, a balance block, a fence and a fan, the rotor main body is provided with a plurality of vent holes, and the plurality of vent holes extend along the axial direction of the rotor main body to penetrate through the rotor main body; the balance block is arranged at one end of the rotor body and used for scattering a refrigerating medium discharged from a silencer of a compressor, the fence is arranged at one end of the rotor body and surrounds the balance block, and the fan is arranged at the other end of the rotor body. And the fan is used for promoting the refrigerating medium to be pumped from one end of the rotor main body to the other end of the rotor main body through the vent hole. According to the rotor assembly, the oil spitting amount of the compressor using the rotor assembly can be reduced, and the operation performance of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotor assembly, a motor with the rotor assembly and a compressor with the motor. Background technique [0002] The refrigerating machine oil of the horizontal compressor is located at the bottom of the compressor shell. During the operation of the horizontal compressor, there is a problem that the rotor beats the refrigerating machine oil. The balance weight on the rotor will loosen and protrude toward the outer circumference of the rotor under the action of beating. Due to the imbalance of the balance weight, the oil output of the compressor will increase. In addition, for some low-voltage compressors with large motor wire diameters, the effect of oil separation is poor, and the refrigerant gas compressed by the compressor contains more refrigeration oil, which will further increase the oil output of the compressor. Contents of the invention [0003] The present inventi...
