Description
Technical field
The invention relates to compressor, the quiet whirlpool of particularly a kind of scroll compressor dish.
Background technique
Fig. 1 is the part sectional view of traditional scroll compressor, and Fig. 2 is the quiet whirlpool dish enlarged view of Fig. 1.As shown in the figure, scroll compressor is by container 11, press part 21, and motor section 31 parts such as grade are formed.The structure of each parts is as follows with effect.Container 11 inside are formed with the storage area of sealing.Press part 21 in container 11 internal upper part zones plays compression refrigerant.Motor section 31 at press part 21 downsides provides power for press part 21.
One side of container 11 is provided with suction pipe 13, can suck refrigerant, and the upside of suction pipe 13 has discharge tube 15 can discharge compressed refrigerant.
The upper inside zone of container 11 is provided with high low pressure separating plate 35, and the downside of high low pressure separating plate has press part 21.Wherein the effect of high low pressure separating plate 35 is to mark off hyperbaric chamber H and low-pressure cavity L.Hyperbaric chamber H can store compressed refrigerant, and the less low-pressure cavity L of relative pressure stores the refrigerant before the compression.
In addition, the center region at quiet whirlpool dish 23 forms compression chamber P between quiet vortex sheet 24 and the moving vortex sheet 29.Can discharge compressed refrigerant in the coolant outlet port 26 that compression chamber P internal run-through chamber wall forms, have expulsion valve 27 can prevent the coolant backflow that is discharged from coolant outlet port 26 upsides.
But the quiet whirlpool dish for traditional turbocompressor has following problem points.Coolant outlet port 26 has single diameter, satisfies the compression ratio that requires on the design specification with this.The switching of expulsion valve 27 is decided by, in the pressure difference of inner compressed refrigerant pressure of compression chamber P and hyperbaric chamber H.Because the pulsation of pressure takes place during compression, so cause the switching instability of expulsion valve 27, expulsion valve 27 also can take place simultaneously combine with the collision of quiet whirlpool dish 23, thereby cause sizable noise.
Also have, in order to solve this noise problem, strengthen displaced volume and the proportional volume that sucks volume than the time, the problem that causes refrigerant pressure to descend because of the coolant quantity deficiency of discharging.
Summary of the invention
In order to overcome the problem that above technology exists, the invention provides the quiet whirlpool of a kind of turbocompressor dish, the noise that can reduce pulsation and therefore produce improves performance simultaneously.
To achieve these goals, the technical solution used in the present invention is: quiet whirlpool dish comprises vortex sheet main body, and first discharges section, more than one enlarged section textural association.Vortex sheet main body and movable orbiting scroll can do relative motion, and combine the compression volume that the back forms refrigerant with movable orbiting scroll, and the vortex sheet main body that wherein has disc-shape has quiet vortex sheet, and quiet vortex sheet has the inward turning shape.Run through the first discharge section that forms behind the center portion of vortex sheet main body, can discharge compressed refrigerant.Along the discharge direction of refrigerant, be communicated with enlarged section on the dirty section of the first discharge section, enlarged section has bigger flow cross-section than the first discharge section and amasss.Said structure can provide the noise that reduces pulsation and therefore produce, and can improve performance simultaneously.
Here, enlarged section has the elliptical section shape.
Enlarged section comprises that second discharges section, and the 3rd discharges section forms more effective.The discharge direction of suitable refrigerant is communicated with second on the dirty section of the first discharge section and discharges section, and the second discharge section has bigger flow cross-section than the first discharge section and amasss.Be communicated with the 3rd on the dirty section of the second discharge section and discharge section, the 3rd discharge section has bigger flow cross-section than the second discharge section and amasss.
Above-mentioned the 3rd discharge section has the ring-type section configuration when plane projection more effective.
Above-mentioned the 3rd discharge section has the elliptical section shape when plane projection more reasonable.
At the thickness direction of vortex sheet main body, form separating surface between the first discharge section and the enlarged section.Following more reasonable several separating surface zone designs between separating surface and each enlarged section.In several separating surface zones, it is long-pending that the discharge direction of the suitable refrigerant at least more than one zone strengthens flow cross-section gradually, thereby have the section configuration of angled section.
In sum, the present invention has following effect: the noise that can reduce pulsation and therefore produce, can improve performance simultaneously.This quiet whirlpool dish comprises vortex sheet main body, and first discharges section, and textural associations such as more than one enlarged section are feature.Vortex sheet main body has disc-shape, and has quiet vortex sheet, and quiet vortex sheet has the inward turning shape.First discharges section forms behind the center portion of running through above-mentioned vortex sheet main body, and can discharge compressed refrigerant.Along the discharge direction of refrigerant, be communicated with enlarged section at the above-mentioned first dirty section of discharging section, enlarged section has bigger flow cross-section than the first discharge section and amasss.
Also have, the quiet whirlpool of the turbocompressor that the present invention proposes dish can be designed to, with required compression ratio, i.e. and the size of exhaust port, the position conforms to, and therefore can improve exhaust port.
Also have, during the dish design of in the past quiet whirlpool, must according to the circularity of the corresponding coolant outlet port of required specification, cylindricity and tolerance of size design turbine just can.But during the turbocompressor that the present invention proposes design, restriction condition reduces relatively, the also corresponding attenuating of the processing request of enlarged section, thus processing is easier.
And the quiet whirlpool of the turbocompressor dish according to the present invention proposes carries out the change of enlarged section shape easily, thereby carries out the thickness of expulsion valve easily, length, the change of size.
