Oil separating device 70 according to the present utility model may be mounted at the exhaust outlet 48 of the compression mechanism 40 of compressor 1
Place.As shown in Figure 1, oil separating device 70 can be arranged in second end cover 13 and partition board 14 or determine vortex component 42 (be not present every
In the case of plate) between.The longitudinal axis (central axis) of oil separating device 70 is roughly parallel to the longitudinal axis of compressor 1
(central axis).Optionally, the longitudinal axis (central axis) of oil separating device 70 can be with the exhaust outlet 48 of compression mechanism 40
Central axis overlap.
It, can be first by oil separating device 70 before the assembling of second end cover 13 with reference to the horizontal type scroll compressor 1 of Fig. 1
Stent 71 is for example fixed to second end cover 13 by welding, then by filtration members 72 (or by inner retainer 74, outer guarantor
Gripping member 76 and/or end holder 75a, 75b and filtration members 72 fit together the component to be formed) it is fitted on stent 71.This
Sample, second end cover 13 can be assembled to the other parts of compressor together with oil separating device 70.Oil separating device 70 is special
It is that its filtration members 72 can preferably abut against partition board 14.In the case where compressor is not provided with partition board 14, oil separating device 70
Particularly its filtration members 72 can directly abut determine vortex component.In order to which filtration members 72 is allowed to be arranged tightly on second end cover 13
Between partition board 14, the stent 71 of oil separating device 70 can be spaced apart against partition board 14 or with partition board 14, for example,
Several millimeters.It is further envisaged that oil separating device is fixed on partition board or determine vortex component.
In the compressor 1 for being equipped with oil separating device 70, can from the pressurized working fluid that compression mechanism is discharged from
Lubricating oil is isolated from the pressurized working fluid before opening compressor, lubricating oil circulation rate is well controllled.On the one hand, may be used
The oil level of oil sump in compressor to be maintained at aspiration level or is maintained at as high as possible level.On the other hand, may be used
Reduce so as to leave the lubricants capacity that compressor enters in compressor assembly, for example, subtracting the lubricants capacity entered in heat exchanger
It is small, so as to improve the whole work efficiency of compressor assembly.
Fig. 7 and Fig. 8 shows the oil separating device 70 ' of comparative examples.As shown in the figure, oil separating device 70 ' includes stent
71 ' and the filtration members 72 ' on the inside of stent 71 '.Stent 71 ' is including being in the end wall 714 ' of polygon and from the outer of end wall 714 '
Multiple axial walls 712 ' of circumferential edges extension.There is gap 715 ' to allow the high pressure work of compression between adjacent axial walls 712 '
Make fluid to flow out from oil separating device 70 '.
In Fig. 7 and comparative examples shown in Fig. 8, stent 71 ' is arranged on the outside of filtration members 72 '.Due to undesirable profit
Lubricating oil submerges stent 71 ', therefore stent 71 ' limits the max-thresholds of the oil level of lubricating oil.Further, since gap 715 ' is deposited
Lubricating oil can be disturbed when being flowed out from the gap 715 ' of neighbouring lubricating oil in, pressurized working fluid, thus may be carried more
Lubricating oil discharges compressor, as depicted by the arrows in figure 7.Filtration members 72 ' are positioned at the inside of stent 71 ', therefore filtration members 72 '
Inside flow area is more than outside flow area.For the structure of Fig. 7 and oil separating device shown in Fig. 8, pressurized working fluid
The speed of oil separating device is flowed through, this is unfavorable for from pressurized working fluid lubricating oil at separation.
In Fig. 1 to oil separating device according to the present utility model shown in fig. 6, filtration members 72 are fitted in the outer of stent 71
Side.Therefore, allow the oil level of lubricating oil can at least to reach near support.In other words, the max-thresholds of oil level can be increased.Oil
The increase of position is conducive to fill enough lubricating oil, and be also beneficial to return to enough lubricating oil before compressor dispatches from the factory
Oil sump S to first end cover 12, so that it is guaranteed that lubrication oil circulations stablize and enough.
In the oil separating device of the utility model, opening can be set only on the first half portion 712a of stent 71, the
It is not provided with being open on two half portion 712b but close.As shown in Figure 1, after oil separating device 70 is installed to compressor,
First half portion 712a corresponds to the first half in a vertical direction, and the second half portion 712b corresponds to lower half in a vertical direction, because
This, the lower half of closing allows to further increase the max-thresholds of oil level.Using the utility model oil separating device it is horizontal
Compressor, the max-thresholds of the oil level in the space of high-pressure side can reach at the central axis of oil separating device or reach sleeping
The 40% of the vertical height of formula compressor or even 50%.
Opening 711,713 is arranged on the first half of stent 71, therefore pressurized working fluid can be booted up to discharge.This
Sample can cause to disturb, and can reduce high-pressure work to avoid pressurized working fluid to the lubricating oil below oil separating device
The flowing velocity of fluid from pressurized working fluid fully to separate lubricating oil.
Since filtration members 72 are fitted in the outside of stent 71, the outside flow area of filtration members is more than inside flow surface
Product, this is more advantageous to coming out the lubricating oil separation in the pressurized working fluid in high-pressure side space and reducing arranging from oil separating device
The speed of the air-flow gone out so as to reduce disturbance of these air-flows to the lubricating oil in the oil sump of high-pressure side, thus further reduces oil
Cycling rate.
Although the various embodiments of the utility model are described in detail herein, it should be appreciated that the utility model is not
The specific embodiment be described in detail and shown here is confined to, in the case of the spirit and scope without departing from the utility model
It may be effected by one skilled in the art other modifications and variant.All these modifications and variant both fall within the utility model
In the range of.Moreover, all components described here can be replaced by component equivalent in other technologies.
