Surface on.Setting enables to working chamber in exhaust process in this way, and the air-flow in working chamber can be generated at groove 21 and be applied
Add the torque with slide plate, so that slide plate is in equilbrium position not run-off the straight always.Wherein, working chamber includes compression chamber and air-breathing
Chamber.Working chamber carries out compression operation while carrying out air-breathing.First flange can be upper flange, and second flange can be laxative remedy
It is blue.Certainly, first flange is also possible to lower flange, and second flange is also possible to upper flange.
In order to enable the torque generated at groove 21 and the torque generated at exhaust passage just to balance out,
Projection of the exhaust passage 11 in second flange 20 is arranged to coincide with groove 21.It is worth noting that, " weight herein
Close " refer to that the projection of shape of exhaust passage 11 and the shape of groove, size are identical.
Further, air balance portion is exhaust hole, is opened in second flange 20 to exhaust hole perforation, exhaust is logical
Hole is oppositely disposed with exhaust passage 11.Setting can equally be played the role of balancing slide plate in this way.Further, exhaust hole
Cross section molded line it is identical as the molded line of the cross section of exhaust passage.
Wherein, annular protrusion 42 is provided on the outer peripheral surface of the shaft 40 of part, annular protrusion 42 is located at air cylinder group
In part 30, sliding vane groove 41 is opened on annular protrusion 42, and sliding vane groove 41 is set along the radial direction extension of annular protrusion 42
It sets.Sliding vane groove 41 be it is multiple, multiple sliding vane grooves 41 along the arranged circumferentially spaced of annular protrusion 42, slide plate 50 be it is multiple, it is more
A slide plate 50 is arranged correspondingly with multiple sliding vane grooves 41, and the inside of cylinder assembly 30 is separated into multiple only by multiple slide plates 50
Vertical working chamber.The performance that can be improved compressor is set in this way.
Further, cylinder assembly 30 includes cylinder 31, rolling member 32 and bearing holder (housing, cover) 33.Rolling member 32 is set to cylinder 31
Interior and be sheathed in shaft 40, sliding vane groove 41 is matched with the inner wall of rolling member 32, by the inner wall of rolling member 32 with turn
Working chamber is separated between axis 40.Bearing holder (housing, cover) 33 is sheathed on rolling member 32, and at least part of bearing holder (housing, cover) 33 is located at cylinder 31
Between inner wall and the outer peripheral surface of rolling member 32, rolling element 34 is provided between rolling member 32 and bearing holder (housing, cover) 33.
Above-described embodiment can be also used for compressor apparatus technical field, i.e., according to another aspect of the present invention, provides
A kind of compressor.The compressor includes pump assembly, and pump assembly is the pump assembly of above-described embodiment.
Above-described embodiment can be also used for air-conditioner device technical field, i.e., according to another aspect of the present invention, provides
A kind of air conditioner, including pump assembly, pump assembly are the pump assembly of above-described embodiment.
Specifically, air balance portion is set on the opposite lower flange of exhaust passage, upper flange exhaust ports can be balanced
Pressure oscillation, reduce disturbance of the pressure to slide plate, to weaken shock of the slide plate to upper and lower end face of flange and bearing.Effectively
The vibration and noise that ground improves slide vane compressor is horizontal.In the present embodiment, the molded line of the cross section of exhaust hole and exhaust
The molded line of the cross section in channel 11 is identical, wherein the length-width ratio of exhaust passage 11 is less than or equal to 4.Preferably, exhaust passage 11
Cross section is diamond structure.
When compressor operation, shaft is rotated with driven by the motor, and slide plate is under the influence of centrifugal force from sliding vane groove
It stretches out, and the inner wall face contact with the inner ring of rolling member.With the even running of compressor, slide plate starts to do in sliding vane groove past
Multiple movement, the head of slide plate and inner wall face contact, and inner ring is driven to be rotated.Wherein, slide plate is 3,3 slide plates and rolling
Entire moon teeth cavity is divided into 3 independent chambers by the inner ring of part, this 3 chambers periodically expand, reduce, to realize compression
The air-breathing of machine, exhaust.In compressor motion process, slide plate and sliding vane groove form a closed space, referred to as slide plate back pressure
Chamber, the slide plate back pressure cavity also there are three, and with the operating of compressor, back pressure cavity is periodically amplified and is reduced.In the pump housing
Component lower part is immersed in compression motor spindle oil sump equipped with pump oil, and shaft rotation drives oil pump rotation, and oil pump is a kind of positive displacement pump,
The effect of oil pump also provides the oil with certain pressure other than the secondary offer lubricating oil that respectively rubs to the pump housing for slide plate back pressure cavity
Pressure.
As shown in Figures 4 to 6, be compressor air-discharging when slide plate position, at this time compressor be in exhaust, exhaust ports gas
For pressure at expulsion Pd.The direction of air-flow is that have cylinder interior to be directed toward outside flange at this time, and airflow direction is vented to slide plate top.By
It is larger in the speed of exhaust ports air-flow, so the pressure of exhaust outlet is lower, and slide plate lower part according to dynamic and static energy transfer principle
Pressure be high pressure, the resultant direction that is subject to of slide plate exhaust side is upward.
As shown in Figure 7 and Figure 8, be slide plate position after compressor air-discharging, at this time slide plate will inswept exhaust passage row
Port, because exhaust ports can retain a part of high pressure gas after compression exhaust, but when slide plate will sweep institute's exhaust outlet, row
The high pressure gas stored at port is also connected to suction chamber, this portion gas is higher than greatly pressure of inspiration(Pi) by reason of heavy pressure, will be gone out
The phenomenon that now crossing expansion, airflow direction are directed toward suction chamber, and resultant force suffered by slide plate suction side also will point to slide plate lower part, stress
Schematic diagram is as shown in Figure 1.In this way, slide plate just will receive a rotating torque under the action of the two resultant forces (F1, F2), at this
Slide plate can generate overturning under the action of a torque, and then encounter upper and lower flange polished surface, generate shock.Due to this shock
The stress for changing slide plate also results in slide plate and hits cylinder, to generate negative vibration of compressor and noise.
As shown in figure 9, opening up a groove on lower flange, position and the upper flange of this groove are arranged symmetrically, but are not got through,
A rotating torque opposite with upper flange exhaust outlet can be generated according to the relationship analysis of stress to balance upper flange exhaust and be produced
Raw torque.So after the rotating torque of slide plate is balanced, the stress of slide plate will be more balanced, so as to avoid slide plate
Topple, to guarantee the reliability service of compressor, reduce the vibration and noise of compressor.
It wherein, further include baffle 61, valve block 62, cover board 63 in pump assembly.Wherein, oil pump 64 is connected with cover board 63.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
