Description
Technical field
The present invention relates to helical-lobe compressor technical field, specially a kind of helical-lobe compressor air inlet seat bottom structure.
Background technique
For helical-lobe compressor, the weight of compressor is bigger, and required material is also more, manufacture processing at
This also can be very high.Loss of weight optimization is carried out to compressor, the dosage of material is can be reduced, can also reduce the manufacturing cost of compressor.Into
Gas seat is the important part of compressor host, and can reduce the heavy parts of compressor host weight.
In the prior art, air inlet seat bottom structure is integral planar, and as shown in Figure 1, air inlet seat weight is big, material consumption
It is more, it is at high cost.
Summary of the invention
Big in order to solve existing air inlet seat bottom heaviness, casting rapidoprint consumes more, at high cost problems, and the present invention mentions
A kind of helical-lobe compressor air inlet seat bottom structure has been supplied, has reduced material while guaranteeing that air inlet seat bottom structure is reliable and stable
Consumption reduces weight and cost.
Its technical solution is such that a kind of helical-lobe compressor air inlet seat bottom structure comprising air inlet seat, feature exist
In the air inlet seat bottom is provided with step, is lower than the backstage terrace close to casing side close to the foreground terrace of end cover side, described
It is connected between foreground terrace and the backstage terrace by bending section, the thickness of the foreground terrace is not less than the bending section
Thickness.
It is further characterized by, the length of the foreground terrace to account for a quarters of the air inlet seat bottom lengths to three
/ mono-；
It is provided with lubricating oil return channel on the inside of the backstage terrace, is provided with oil return opening on the inside of the foreground terrace；
The bending section medial surface includes sequentially connected first angled straight lines section, the first arc section, longitudinal straightway, described curved
Tune lateral surface includes sequentially connected second angled straight lines section, the second arc section, third arc section, second arc section with
The third arc section bending direction is opposite；
The first angled straight lines section is parallel to each other with the second angled straight lines section, first arc section and second circle
Segmental arc arranged concentric, the radius of the third arc section are greater than the first arc section radius and less than the second arc section radiuses.
After applying the present invention, the plane of air inlet seat bottom is changed to step surface, eliminates some materials, reduce air inlet seat
Weight reduces costs, and the thickness of foreground terrace is not less than the thickness of bending section, is able to bear stress complicated at this,
Guarantee the reliable and stable of structure.
Detailed description of the invention
Fig. 1 is existing structure schematic diagram；
Fig. 2 is schematic structural view of the invention；
Fig. 3 is enlarged diagram at I in Fig. 2.
Specific embodiment
See Fig. 2, shown in Fig. 3, a kind of helical-lobe compressor air inlet seat bottom structure comprising air inlet seat 1,1 bottom of air inlet seat
It is provided with step, is lower than the backstage terrace 3 close to casing side, foreground terrace 2 and backstage terrace close to the foreground terrace 2 of end cover side
It is connected between 3 by bending section 4, the thickness h 1 of foreground terrace 2 is not less than the thickness h 2 of bending section 4, i.e. h2 >=h1, backstage terrace
3 insides are provided with lubricating oil return channel 5, and oil return opening 6 is provided on the inside of foreground terrace 2, and h3 is that bottom is returned to lubricating oil in figure
The thickness in oily channel 5.The length of foreground terrace 2 accounts for a quarters of 1 bottom lengths of air inlet seat to one third.
4 medial surface of bending section includes sequentially connected first angled straight lines section CD, the first arc section BC, longitudinal straightway
AB, 4 lateral surface of bending section include sequentially connected second angled straight lines section EF, the second arc section FG, third arc section GH, and second
Arc section FG is with third arc section GH bending direction on the contrary, the first angled straight lines section CD and the second angled straight lines section EF are mutual in figure
In parallel, the radius R3 of the first arc section BC and the second arc section FG arranged concentric, third arc section GH is greater than the first arc section BC
Radius R1 and it is identical less than the center of circle of the second arc section FG radius R2, the first arc section BC and the second arc section FG be O1,
One angled straight lines section CD and line segment PD extended line angle are a, and 20 °≤a≤40 °, longitudinal straightway AB extends perpendicular to line segment PD
Line, R2=R1+h2 guarantee the thickness of bending section.
The present invention compared with the existing, mitigates air inlet seat weight, reduces material consumption, reduces cost, structure is also simple, does not have
Have and do complicated structure and improve, casting and processing are all easier, but structure can guarantee it is reliable and stable, in addition, lubricating oil
Drainback passage and oil return opening have drop, facilitate oil return.
