Abstract
The utility model discloses a rotor of a refrigeration compressor. The rotor is characterized in that the rotor is provided with a rotor axial slot (3) and a rotor radial slot (4), wherein a spray pipe (6) and a deflector (5) are arranged on one side of the rotor. In the rotor, the deflector is arranged, so that the performances of a motor are greatly improved under the condition that the same material is used; and in addition, a refrigerant can be fully and effectively used and the energy-efficiency ratio of the compressor is improved.
Description
Technical field
The utility model relates to a kind of rotor that is used for refrigeration compressor.
Background technique
The characteristics of refrigeration compressor motor special are: volume is little, exert oneself big, efficient is high, directly cool off with refrigeration agent, adopts high electromagnetic load during design, and motor volume is compared little by 45% with the same specification y series motor.At these characteristics, not only to optimize electromagnetic scheme design and adopt new material, more to optimize the cooling channel design, but generally the cooling of rotor be thinked little of.The cooling of general refrigeration rotor is divided into, and 1. adds refrigerant from middle part, stator core surface, divides two limits to flow to whole motor, middle part stator core segmentation, from then on refrigerant enters stator core, and this mode rotor cooling situation is undesirable, so motor speed is relative with efficient on the low side; 2. from rotor axial with radially open the wind hole slot, enter through special-purpose guiding device, flow to the other end respectively and enter the stator air gap cooling stator core from the rotor radial groove by rotor one end; The special-purpose guiding device cost of this mode height, the rotor axial overlap span is the same, because silicon steel plate axial direction thermal conductivity specific diameter to far short of what is expected times, causes the rotor axial non-uniform temperature, causes motor oscillating big when serious.
Summary of the invention
The purpose of this utility model is to provide a kind of can effectively fully use refrigerant, improves the refrigerant compression machine rotor of compressor Energy Efficiency Ratio.
The technical solution adopted in the utility model is: a kind of refrigerant compression machine rotor is characterized in that: have rotor axial groove and rotor radial groove on the described rotor, be distributed with a jet pipe and fluid director in a side of rotor.
The utility model has under equivalent material because fluid director is arranged, and motor performance improves greatly, and can fully effectively use refrigerant, improves the compressor Energy Efficiency Ratio.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Among the figure, the 1st, stator, the 2nd, rotor, the 3rd, rotor axial groove, the 4th, rotor radial groove, the 5th, fluid director, the 6th, jet pipe.
Embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawings below:
As can be seen from Figure 1, the utility model refrigerant compression machine rotor has rotor axial groove 3 and rotor radial groove 4 on rotor, is distributed with a jet pipe 6 and fluid director 5 in a side of rotor.
Working method: the refrigerant that comes out from jet pipe 6 passes through fluid director 5 guiding rotors 2, flow to the other end and the stator core of rotor along rotor axial groove 3 and rotor radial groove 4, simultaneously by regulating the size of rotor radial groove at the axial aperture area, thereby make motor shaft reasonable to rotor refrigerant distributed uniform, the whole motor temperature difference is less than 20 ℃.
Claims (1)
1. refrigerant compression machine rotor is characterized in that: have rotor axial groove (3) and rotor radial groove (4) on the described rotor, be distributed with a jet pipe (6) and fluid director (5) in a side of rotor.
