Description
Technical field
The present invention relates to compressor field, in particular to a kind of exhaust pipe structure and compressor.
Background technology
The structure of current helical-lobe compressor is less than normal, and inner space is compact, and exhaust end Flow Field Distribution is uneven, some areas stream
Road is too short, causes oil gas not to be kept completely separate and is just over, and oil is relatively inefficient.Because oil is inefficient so that
System needs to improve its recirculating oil quantity, just can guarantee that compressor stable operation, and recirculating oil quantity is raised greatly influences compressor volume again
Efficiency, so as to the performance for causing compressor is reduced.
The content of the invention
The present invention is intended to provide a kind of exhaust pipe structure and compressor that can improve oil efficiency.
The invention provides a kind of exhaust pipe structure, along airflow direction, converging transition and divergent segment that blast pipe inside has.
Further, the end of converging transition is connected with the head end of divergent segment.
Further, guiding gutter is set on the inwall of converging transition.
Further, guiding gutter is spiral stream guidance groove.
Further, converging transition is taper converging transition, and divergent segment is taper divergent segment.
Further, cone angle of the cone angle of taper converging transition more than taper divergent segment.
Further, the cone angle of taper converging transition is 20 ° to 30 °.
Further, α is 28 °.
Further, the cone angle beta of taper divergent segment is 20 ° to 30 °.
Further, β is 22 °.
Present invention also offers a kind of compressor, including foregoing exhaust pipe structure.
Exhaust pipe structure of the invention and compressor, by setting converging transition and divergent segment, in exhaust process, oil gas
Mixture can collide the internal face of blast pipe converging transition so that Oil-gas Separation.Then by divergent segment, air-flow gradually expands, most
Blast pipe is more equably discharged afterwards.The relatively existing exhaust process of whole process, its runner is obviously prolonged, and increased collision
Separation process, effectively improves oil efficiency.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate, for explaining the present invention, not constitute inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the axial cross section structure diagram of exhaust pipe structure of the invention.
Description of reference numerals：
10th, converging transition；11st, guiding gutter；20th, divergent segment.
Specific embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, exhaust pipe structure of the invention, along airflow direction, the converging transition 10 that blast pipe inside has
With divergent segment 20.By setting converging transition 10 and divergent segment 20, in exhaust process, gas mixture can collide blast pipe to the present invention
The internal face of converging transition 10 so that Oil-gas Separation.Then by divergent segment 20, air-flow gradually expands, and finally more equably arranges
Exhaust pipe.The relatively existing exhaust process of whole process, its runner is obviously prolonged, and increased collision separation process, effectively
Improve oil efficiency.
Specifically, the end of converging transition 10 is connected with the head end of divergent segment 20 so that can by the air-flow of converging transition 10
Immediately enter divergent segment 20 to expand, effect is streamed in increase, improve separative efficiency.
Preferably, guiding gutter 11 is set on the inwall of converging transition 10, is on the one hand conducive to improving separating effect；The opposing party
Face, the oil backflow after being also beneficial to separate.It is highly preferred that guiding gutter 11 is spiral stream guidance groove 11, so as to promote gas mixture
Rotation, improves oil-gas separation efficiency under the influence of centrifugal force.
With reference to shown in Fig. 1, in the present invention, converging transition 10 is taper converging transition, and divergent segment 20 is taper divergent segment, so that
Make air-flow uniform shrinkage and expansion, be also convenient for processing.Usually, the cone angle of taper converging transition is more than the cone angle of taper divergent segment,
It is more beneficial for making oil gas collide separation, strengthens oil efficiency.
The design of the cone angle, the cone angle of taper divergent segment and guiding gutter 11 of taper converging transition needs to consider different type of machines
Extraction flow, and consider the pressure loss.Usually, the principle for choosing cone angle is just on the premise of pressure and flow velocity is met, to the greatest extent
The possible length for increasing runner.Definition exhaust pipe length is full-length, is computed, and the cone angle of converging transition 10 is at 20 ° to 30 °
Effect is more excellent；Preferably, α is 28 °.It is more excellent that the cone angle beta of divergent segment 20 is selected in 20 ° to 30 ° effects；Preferably, β is 22 °.Guiding gutter
11 design mainly considers to reduce the pressure loss while extending flow channel length.Optimization guiding gutter 11 can be by channel interior stream
Field carries out analogue simulation, it is ensured that exit velocity is relatively uniform.According to analysis corrections, the guiding gutter 11 of helical wire form is vented most uniform
And the pressure loss is relatively small, reasonably cone angle and guiding gutter 11 are designed, it is ensured that air-flow by blast pipe flow losses
As small as possible, exhaust is more uniform, and oil-gas separation efficiency is high.
Present invention also offers a kind of compressor, including foregoing exhaust pipe structure, so as to improve oil efficiency, not only may be used
To reduce the overall dimensions of compressor, moreover it is possible to lift the coefficient of performance of compressor.If oil efficiency is sufficiently high, or even energy
It is enough to be simplified external oil, reduce package size.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
Exhaust pipe structure of the invention and compressor, by setting converging transition 10 and divergent segment 20, in exhaust process,
Gas mixture can collide the internal face of blast pipe converging transition 10 so that Oil-gas Separation.Then by divergent segment 20, air-flow is gradually
Expansion, finally more equably discharges blast pipe.The relatively existing exhaust process of whole process, its runner is obviously prolonged, and increases
Add collision separation process, effectively improve oil efficiency.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
