Abstract

The utility model relates to a scroll compressor whirlpool dish and wear pad's structure, including the vortex dish of wear pad and formation tangible line, wear pad hugs closely on the bottom surface of vortex dish, and its characterized in that opens the slot that has with the same shape of shape line on the bottom surface of vortex dish, and the slot is located between two strip lines, and the compression chamber department that corresponding pressure is the biggest on wear pad opens the through -hole that the diameter is suitable with the slot width, and the slot gets up via intercommunication between through -hole and scroll compressor's the high pressure chest. The utility model discloses a division slot is gone up to the bottom face between the line of compressor whirlpool, utilizes high -pressure refrigerant will have the wear pad of high -pressure through -hole to lift up to carry and guaranteed the wearability and the leakproofness of cross -examining in the whirlpool. Will the utility model discloses be applied to current scroll compressor, under the prerequisite that does not change original structure, promoted refrigeration effect and compressor life under long -time the use.

Description

The structure of swirl compressor spinning disk and wear plate

Technical field

The utility model is related to a kind of whirlpool disk and the structure of wear plate for screw compressor.

Background technology

The energy and problem of environmental pollution are one of significant problems that the world today faces, and the energy is modern society and life Material base, as world population increases sharply with economic, the consumption of the energy is sharply increased, and causes environmental pollution constantly to add It is acute.

Screw compressor with its energy-efficient, low noise, it is stable the advantages of favored by people deeply.As shown in figure 1, For existing scroll compressor structure schematic diagram, in figure, 1 represents that wear plate, 2 represent that exhaust outlet, 3 represent that high pressure refrigerant, 4 represent Refrigerant flow direction, 5 represent that low pressure refrigerant, 6 represent that air entry, 7 represent scroll plate.As shown in Fig. 2 be the structure of existing scroll plate 7, As shown in figure 3, be the structure of existing wear plate 1, as shown in figure 4, being combined rear schematic diagram with wear plate 1 for existing scroll plate 7. With reference to Fig. 5, the bottom of existing scroll plate 7 is complete plane, and wear plate 1 is close on the bottom surface of scroll plate 7, will by wear plate 1 The scroll plate 7 of a pair of fastenings is spaced apart, when preventing high-speed motion, the phase mutual friction between two scroll plates 7, in playing compression process Solve the problems, such as to move abrasion between scroll plate 7.

Existing wear plate 1 needs when mounted the thickness by measuring the height of scroll plate 7 to determine wear plate 1.If Wear plate is too thin, the interior leakage between compression chamber, pressure at expulsion can be caused not to reach design requirement, the refrigeration for affecting compressor overall Amount and Energy Efficiency Ratio；If wear plate 1 is too thick, can cause to axially engage tension between two scroll plates 7 so that compressor can not be just Often work.

The content of the invention

The technical problems to be solved in the utility model is：Ensure that compressor will not cause system because the apolegamy of wear plate is bad The reduction of cold and Energy Efficiency Ratio, and cisco unity malfunction.

In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of swirl compressor spinning disk and The structure of wear plate, including the scroll plate of wear plate and the tangible line of formation, wear plate is close on the bottom surface of scroll plate, its feature It is that the groove with shape line same shape is provided with the bottom surface of scroll plate, groove is located between the two neighboring lines of shape line, Open a diameter through hole suitable with groove width on the wear plate at the maximum compression chamber of corresponding pressure, groove via through hole and Connection between the high pressure chest of screw compressor is got up.

Preferably, the distance between the width of the groove and two neighboring lines of shape line in the scroll plate into than Example.

The utility model will have height by opening a groove in the bottom faces between the line of compressor whirlpool using high pressure refrigerant The wear plate of pressure through hole is lifted, so as to put forward the wearability and sealing that ensure that whirlpool is cross-examined.The utility model is applied to existing Screw compressor, on the premise of original structure is not changed, improve refrigeration and compressor under long-time use Service life.

Specific embodiment

To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

In the structure of a kind of swirl compressor spinning disk provided by the utility model and wear plate, the structure of scroll plate 8 As shown in fig. 6, opening a groove 11 in the bottom of scroll plate 8, the shape of groove 11 is identical with the shape of shape line 9, and groove 11 Between the two neighboring lines of shape line 9.The width of groove 11 is designed with the distance between two strip lines 9, to facilitate processing It is advisable.

In the utility model, the structure of wear plate 10 is as shown in fig. 7, the maximum compression of corresponding pressure on wear plate 10 A through hole 12 suitable with the width of groove 11 with diameter is opened at chamber.

With reference to Fig. 8 to Figure 10, wear plate 10 is loaded into scroll plate 8, and after a pair of scroll plates 8 are mutually fastened, groove 11 leads to Cross and connected between through hole 12 and the high pressure chest of screw compressor, groove 11 and wear plate 10 form a space.Work as vortex In the running, the compression refrigerant of scroll plate 8, the high pressure refrigerant after compression enters groove 11 to compressor from the through hole 12 of wear plate 10 Space, by high pressure refrigerant by the up lifting of wear plate 10, so that wear plate 10 begins with the shape line 9 of another scroll plate 8 Keep eventually completely attaching to, improve the sealing between scroll compression chamber, can play again prevents the rubs mutually of scroll plate 8.And Even if compressor long-time improves the reliability of compressor using the possibility for being also not in later sealing variation so that Compression function is using the longer time without there is inoperable phenomenon.
