Abstract
The invention provides a structure for sealing end surfaces between scroll plates of a scroll compressor. The structure comprises the scroll plates, wherein sealing grooves are formed in the end surfaces of the scroll plates; sealing strips are arranged in the sealing grooves; and gaps are reserved between the sealing grooves and bottoms of the sealing strips; and a hole is formed in one end of each sealing groove, the hole communicates with the gap, a compressed refrigerant is introduced from the hole so as to lift up the sealing strip, and thus the sealing strip makes complete contact with the bottom of the other scroll plate all the time. When the compressor runs, the scroll plates compress the refrigerant, the compressed high-pressure refrigerant enters the bottom space of each sealing groove via the hole in one end of the sealing groove, and the sealing strip is lifted up by the aid of the high-pressure refrigerant and makes complete contact with the bottom of the other scroll plate all the time. With the structure, the sealing performance of the end surfaces between the scroll plates is improved, the sealing performance of a compression system is more reliable and cannot be reduced due to long use time, the refrigeration effect after long-time use is improved, the discharge pressure of the compressor is guaranteed, and the service life of the compressor is prolonged.

Screw compressor is energy-efficient with it, low noise, the advantage such as stable are favored by people deeply.Tradition
Scroll compressor structure as it is shown in figure 1, include casing 3, in casing 3, be respectively arranged at two ends with department of electrical engineering
System 1 and compressibility 2, electric system 1 is worked by main shaft drives compressibility 2.Electric system 1 side
Being provided with low pressure chamber top and be provided with low pressure air suction mouth 11, the high pressure chest top of compressibility 2 side is provided with high pressure
QI KOU 21.Low pressure refrigerant A enters from low pressure air suction mouth 11, enters compressibility 2 along arrow K direction
It is compressed, low pressure refrigerant A is compressed into high pressure coolant B, finally from high-pressure exhaust 21, coolant is discharged,
Form a complete coolant compression process.
Being provided with scroll plate (also known as whirlpool dish) 4 in compressibility 2, between traditional whirlpool dish, the structure of end face seal is such as
Shown in Fig. 2～Fig. 4, sealing strip 5 is filled up completely with the seal groove in full scroll plate 4, highlights by sealing strip 5
Face seals, and plays and solves the problem of internal hemorrhage due to trauma between different compression chamber in compression process.
Above-mentioned sealing structure fully relies on sealing strip and exceeds some surpluses of end face and seal, along with making for a long time
With, sealing strip fair wear and tear, ultimately result in generation internal hemorrhage due to trauma between each compression chamber, cause coolant compression not exclusively,
Affect the overall refrigerating capacity of compressor and Energy Efficiency Ratio.
Summary of the invention
The technical problem to be solved in the present invention is how to promote the sealing property of end face between swirl compressor spinning disk, makes
Must compress function use longer time and refrigeration will not decline.
In order to solve above-mentioned technical problem, the technical scheme is that and hold between a kind of swirl compressor spinning disk of offer
The structure of face seal, including scroll plate, the end face of scroll plate is provided with seal groove, is provided with sealing strip in seal groove,
It is characterized in that: between bottom described seal groove and sealing strip, leave gap；One end of described seal groove be provided with
Described gap is through, and the coolant after being passed through compression is with by the up lifting of described sealing strip so that described close
All the time the hole completely attached to bottom strip of paper used for sealing and another scroll plate.
Preferably, the width in described hole is more than described seal groove；The degree of depth in described hole is identical with described seal groove.
Preferably, described sealing strip matches with seal groove superstructure, but the degree of depth of described seal groove is more than close
Strip of paper used for sealing.
Preferably, described seal groove side is provided with step, and described sealing strip side also is provided with and described seal groove phase
The step of coupling.
Preferably, described seal groove both sides are provided with step, and described sealing strip both sides also are provided with and described seal groove phase
The step of coupling.
When compressor is operating when, and scroll plate compression refrigerant, the high pressure coolant after compression is from seal groove simultaneously
The hole of one end enters the bottom space of seal groove, utilize high pressure coolant by sealing strip up lifting so that close
Strip of paper used for sealing completely attaches to bottom another scroll plate all the time.
The present invention, by opening a seal groove with the level on the line end face of compressor whirlpool, utilizes high pressure coolant
Sealing strip is lifted, thus improves end face seal between the dish of whirlpool, the sealing of scroll compressor compresses system can be made
Property relatively reliable, sealing will be caused to be deteriorated because the use time is permanent, improve under long-time use
Refrigeration, it is ensured that the pressure at expulsion of compressor, adds the service life of compressor.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate
The present invention rather than restriction the scope of the present invention.In addition, it is to be understood that read the present invention lecture content it
After, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within this equally
Application appended claims limited range.
Embodiment 1
The structural representation of end face seal between the swirl compressor spinning disk that Fig. 5 provides for the present embodiment, in conjunction with figure
6～Fig. 8, between described swirl compressor spinning disk, the structure of end face seal is to open one on the end face of scroll plate 4
Seal groove 41 with the level, opens a hole 42 more than seal groove width, hole in one end of this seal groove 41
The degree of depth of 42 is identical with seal groove 41；Sealing strip 5 with the level, seal groove is loaded onto again in seal groove 41
