Specific embodiment
In conjunction with referring to shown in Fig. 1, Fig. 2, embodiment according to the present utility model provides a kind of vortex pump housing, including phase
Quiet disk 1, the Moving plate 2 mutually engaged, and it is used to support the supporting support 3 of the quiet disk 1 and the Moving plate 2, crankshaft 7 passes through bearing
Bearing bore 61 is connect and formed with the supporting support 3, and the Moving plate 2 is configured with lubricating oil towards 3 side of supporting support
Road 5 forms back pressure cavity 62 between the Moving plate 2 and the supporting support 3, the oil leab 5 can be with the Moving plate 2
The perforation bearing bore 61 and back pressure cavity 62 of selectivity are slided, oil transportation channel 71 is provided in the axis of the crankshaft 7, described
When the pump housing is run, the lubricating oil of 7 lower section of crankshaft will be delivered in the bearing bore 61 via the oil transportation channel 71, at this time may be used
With understanding, the pressure in the bearing bore 61 is consistent with pressure at expulsion, and the pressure in the back pressure cavity 62 then with
Pressure of inspiration(Pi) or intermediate pressure are consistent, and the oil leab 5 will make the bearing bore 61 with pressure difference and back as a result,
Press the perforation of the selectivity of chamber 62, as previously mentioned, selectivity perforation here make to be controlled by the Moving plate 2 with respect to sliding mode and
Speech, specifically, can be controlled by the way of electrically-controlled valve the conducting situation of oil leab 5.In the technical solution, lead to
It crosses on the Moving plate 2 and the oil leab 5 is set penetrates through the bearing bore 61 optionally with back pressure cavity 62, it is thus real
Now guarantee the injection of lubricating oil using the pressure characteristic that the bearing bore 61 is higher than back pressure cavity 62, this prevent adopt in the prior art
Have the defects that low on fuel when pump oil into the back pressure cavity 62 with lubricating oil in oil sump, thus ensure that the Moving plate 2 with
1 lubricants capacity of quiet disk, ensure that pump housing lubricant effect, and then improve the working performance of the pump housing.
Front gives a kind of mode of optional perforation that the oil leab 5 is realized by the way of automatically controlled valve body,
And it is understood that on the one hand this mode needs to be arranged the space of corresponding valve body, have it in mounting arrangement certain
Difficulty, meanwhile, the control system of the pump housing is also required to carry out necessary improvement and is precisely controlled with realizing to it, it is seen then that this side
Shortcomings in the realization of formula, and be preferably able to be improved appropriately based on the existing structure of the current pump housing, so that structure is more
Add that simple, control is more flexible, being provided with sealing ring 4 between the existing supporting support 3 and the Moving plate 2 (can be used PTFE
The sealing ring of material), the oil leab 5 has import 51 and outlet 52, and the import 51 is penetrated through with the bearing bore 61, institute
State the width that width of the outlet 52 in the glide direction of the Moving plate 2 is less than the sealing ring 4.At this point, due to the outlet
52 width in the glide direction of the Moving plate 2 is less than the width of the sealing ring 4, therefore can guarantee in the Moving plate 2
When relative to the sealing ring 4 sliding, the import 51 can be blocked completely in sliding process by the sealing ring 4, without
The sealing effect of pressure at expulsion and pressure of inspiration(Pi) or intermediate pressure is influenced, namely is only just made in the moment that needs lubricate described
Bearing bore 61 and back pressure cavity 62 penetrate through.
When the crankshaft 7 operating, the Moving plate 2 carries out the eccentric center translation of eccentric diameter r around the crankshaft 7, by institute
It is fixed to state supporting support 3, when the Moving plate 2 carries out eccentric center translation, the sealing ring 4 carries out sliding on Moving plate 2 close
Envelope, sliding area most inner side diameter are R1, and the diameter of dehiscing of the sealing ring 4 is R, then R1=R-r.When the sealing ring 4
Slide into close or when to the place most inner side diameter R1, the outlet 52 is connected with the back pressure cavity 62, in intermediate pressure (or suction
Atmospheric pressure), and lubricating oil is full of in the bearing bore 61, and under pressure at expulsion, under the action of pressure difference, the bearing
Lubricating oil in chamber 61 can be flowed into the back pressure cavity 62 by the oil leab 5, so that reaching momentary stabilization increases the pump housing
Internal lubrication oil mass, this structure are not influenced by lubricants capacity in upper bracket oil sump.
Further, the first circle, the outlet are formed with the R1 using the geometric center O of the supporting support 3 as the center of circle
52 be circular hole, and the outlet 52 and first circle are tangent or intersect, in the technical solution, to it is described export 52 position into
Go optimization, when there is the oil leab 5 a plurality of namely described outlet 52 to have multiple, 52 such schemes of the outlet
Setting, can guarantee that the outlet 52 of oil leab 5 adjacent thereto will not synchronize perforation, and then can effectively control into institute
State the lubricants capacity in back pressure cavity 62.
The oil leab 5 further includes connecting pipe 53, and the connecting pipe 53 is connected to the import 51 and outlet 52
Between, it can be a variety of runner patterns, such as shaped form, broken line for the flow path for circulating in lubricating oil therein
Type or multistage Straight Combination type etc., and best, the radially extending along the Moving plate 2 of oil leab 5, namely wherein
Lubricating oil flow path be along the Moving plate 2 radial direction from inside to outside, this advantageously ensures that the flowing of lubricating oil is suitable
Smooth property.
As previously mentioned, the oil leab 5 can have a plurality of, circumferential direction of a plurality of oil leab 5 along the Moving plate 2
It is uniformly distributed, this can guarantee more moment repairings of the lubricating oil, be conducive to the further promotion of lubricant effect.
Embodiment according to the present utility model also provides a kind of compressor, especially a kind of vertical compressor, including above-mentioned
The pump housing, can significantly improve the lubricants capacity of Moving plate Yu quiet disk, guarantee pump housing lubricant effect, and then promote the workability of the pump housing
Energy.
