Abstract
The utility model relates to a vortex-type compressor with a small exhaust pulsating quantity. The vortex-type compressor comprises a rear shell assembly (1), wherein the rear shell assembly (1) is provided with an air inlet (2) which is communicated with an exhaust cavity of a stationary plate, a weight-reduction cavity (3) is arranged on the periphery of the air inlet (2), the other end of the air inlet (2) is communicated with an exhaust port (4). The vortex-type compressor is characterized in that the air inlet (2) is provided with an opening (5) which is communicated with the weight-reduction cavity (3), the high-temperature and high-pressure gas exhausted from the exhaust cavity of the stationary plate enters the air inlet (2), partial gas enters the weight-reduction cavity (3) to be exhausted to the rear shell assembly (1) together with the part of gas exhausted from the exhaust port (4) after being buffered. By improving the rear shell assembly, the distribution of the airflow can be realized, the pulse can be reduced by more than 50 percent, and the exhaust noise can be greatly lowered.
Description
Technical field
The utility model relates to a kind of scroll compressor, the improved scroll compressor of especially a kind of exhaust mode, the specifically little scroll compressor of a kind of exhaust pulsating quantity.
Background technique
As everyone knows, the exhaust of scroll compressor is pulsed, due to the High Rotation Speed of compressor, its ripple frequency is very high, and this just causes exhaust pulsation large, make the exhaust sound of compressor high, be one of important noise source of compressor, therefore, reducing compressor air-discharging pulsating quantity is one of important measures that reduce total noise of centrifuge, and main method is by installing the means of curing the symptoms, not the disease of baffler and so on additional at present, must be improved.
Summary of the invention
The purpose of this utility model is because exhaust pulsation rate is high, to cause the problem that noise is large for existing scroll compressor, designs the little scroll compressor of a kind of exhaust pulsating quantity.
The technical solution of the utility model is:
The little scroll compressor of a kind of exhaust pulsating quantity, it comprises rear shell component 1, rear shell component 1 is provided with the suction port 2 being connected with quiet dish exhaust cavity, suction port 2 is provided with loss of weight cavity 3 around, the other end of suction port 2 is connected with relief opening 4, it is characterized in that described suction port 2 is provided with the opening 5 being connected with described loss of weight cavity 3, the high temperature and high pressure gas that quiet dish exhaust cavity is discharged enters suction port 2 one end and divides and enter in loss of weight cavity 3 after buffering and the other end in the lump shell component 1 from relief opening 4 discharges.
The quantity of described opening 5 is less than the quantity of loss of weight cavity 3.
The beneficial effects of the utility model:
The utility model, by the improvement to rear shell component, is realized the shunting of air-flow, can reduce pulse more than 50%, greatly reduces exhaust sound.
Accompanying drawing explanation
Fig. 1 is existing exhaust structure schematic diagram.
Fig. 2 is exhaust structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 2.
The little scroll compressor of a kind of exhaust pulsating quantity, it comprises rear shell component 1, rear shell component 1 is provided with the suction port 2 being connected with quiet dish exhaust cavity, suction port 2 is provided with loss of weight cavity 3 around, the other end of suction port 2 is connected with relief opening 4, it is characterized in that described suction port 2 is provided with the opening 5 being connected with described loss of weight cavity 3, the high temperature and high pressure gas that quiet dish exhaust cavity is discharged enters suction port 2 one end and divides and enter in loss of weight cavity 3 after buffering and the other end in the lump shell component 1 from relief opening 4 discharges.During concrete enforcement, the quantity of described opening 5 is preferably less than the quantity of loss of weight cavity 3.
Arrow in Fig. 1 is that in existing scroll compressor relief opening, air-flow moves towards schematic diagram, therefrom can find out, air-flow can form circulation in exhaust cavity, increase pulsed quantity, Fig. 2 is that air-flow of the present utility model moves towards signal, as can be seen from Figure 2, the utility model has been eliminated the circulation shown in Fig. 1, therefore the quantity of pulsing obviously reduces, and according to experiment test, pulse number can reduce by 50% left and right.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
Claims (2)
1. the scroll compressor that exhaust pulsating quantity is little, it comprises rear shell component (1), rear shell component (1) is provided with the suction port (2) being connected with quiet dish exhaust cavity, suction port (2) is provided with loss of weight cavity (3) around, the other end of suction port (2) is connected with relief opening (4), it is characterized in that described suction port (2) is provided with the opening (5) being connected with described loss of weight cavity (3), the high temperature and high pressure gas that quiet dish exhaust cavity is discharged enters suction port (2) one end and divides and enter in loss of weight cavity (3) after buffering and the other end in the lump shell component (1) from relief opening (4) discharge.
2. the little scroll compressor of exhaust pulsating quantity according to claim 1, is characterized in that the quantity of described opening (5) is less than the quantity of loss of weight cavity (3).
