Field, when designing centrifugal compressor, it is necessary to consider many factors, as reduced production cost；Improve pressure
Contracting machine work efficiency.
The centrifugal compressor that major part petrochemical enterprise is applied at present has the compressor of horizonally split formula, cartridge type
Compressor (i.e. vertical subdivision), Axial Flow Compressor etc., the gas of the compressor conveying of these kinds be all from
The import of one end enters in compressor, by exporting from the outlet of the other end after the supercharging of rotor, enters into user
Process pipelines in, being divided into two sections or the compressor of three sections even if having, being that gas temperature is too high, passing the gas through
Cooler reaches the effect of cooling, again returns to, in compressor, improve pressure.
The efficiency the most effectively making compressor improves, the time lengthening in service life, reduces maintenance cost, carries
Compressor for a kind of high efficient and reliable becomes the target pursued for the art scientific and technical personnel.
Chinese patent CN1015489B discloses one " multistage centrifugal compressor ", it is characterised in that: compressor
Each impeller and connected diffuser composition one-level, compressor at least four centrifugal rotors and at least four
Individual lead vane type diffuser (i.e. vane diffuser).That is told leads in vane type diffuser before the stator of previous diffuser
The ratio of edge radius and rotor outlet radius is more than the same ratio of later diffuser, and a rear diffuser is from discharge
The relatively described previous diffuser in side is near.Except have lead described in vane type diffuser at different levels in addition to, the most at least
One-level is without stator diffuser.Owing to the rotation desulfurization in diffuser is in backflow development and to be formed in diffuser rotation
Produce during the backflow band turned, and lead vane type diffuser by starting that backflow position occurs without stator diffuser
Inner side arranges stator leading edge, has the effect of anti-backflow, and so, the backflow occurred at the beginning in return channel is i.e.
It is suppressed, also avoids to rotate the generation of desulfurization, such that it is able to make compressor reach the highest efficiency, and can
To work in wider scope.
Chinese invention patent application case CN102434491A discloses one " centrifugal compressor ", described blade
The stator of diffuser by trailing edge radius is identical and that length is different long and short stator forms, adjacent long stator it
Between at least configure a piece of short-range missile leaf, utilize the rectified action of short-range missile leaf, improve the performance of compressor.
Though the product of above-mentioned all inventions is applied the most in the industrial production, but some aspect of its product also has
The leeway improved, and innovation the biggest in technique.It is contemplated that, if a compressor compression
Gas can supply a plurality of process pipelines, and this will bring bigger benefit to user.Main by product
Active wheel (i.e. impeller) on parts i.e. rotor and rotor, the also sealing device of compressor, the shape etc. of casing
All manifold research, it is believed that the work efficiency of compressor can also be improved, the maintenance cost of saving, very
All can significantly extend as its working range, the starting point of this our research work just.
Utility model content
For the weak point in existing technology, this utility model provides a kind of in the middle of petroleum chemical industry
The centrifugal compressor that inter-stage is bled, gas its gas pressure after compression i.e. entered in compressor inlet reaches
Pressure required by user, thus can extract compressed gas for process pipelines out by air duct of bleeding,
And remaining compressed gas proceeds after compression for other process pipelines, improve the use of compressor
Efficiency.
This utility model provides a kind of inter-stage and bleeds centrifugal compressor, and it mainly includes: main shaft, impeller,
Spacer, thrust disc, balancing frame, diaphragm coupling, diffuser, return channel, bend, import and export volute casing, close
Envelope, bearing group parts, housing etc., it is characterised in that:
(1) housing of compressor is divided into upper and lower two bodies from the horizontal plane of rotating shaft, and both are by compressor two ends
Seal connects and fixes；
(2) part such as impeller, spacer, balancing frame, thrust disc is arranged on main shaft the rotor forming compressor,
Rotor is arranged on lower house by bearing and bearing block；
(3) it is fixed on bearing below the lower house of compressor, is front and back provided with inlet, outlet below, in
Between be provided with a chimney fan bled.
The size of the impeller on centrifugal compressed machine rotor of the present utility model is two kinds, before chimney fan of bleeding is
Big impeller ensures suction pressure, afterwards for small impeller compression further to gas, such design can improve
The work efficiency of this product and service efficiency；
The impeller of centrifugal compressor of the present utility model uses ASTM 705A rustless steel double shrouded wheel, with weldering
Connecing process forming, blade uses the blade shape of palintrope structure, compared with the unshrouded impeller of other products, machine
The whole efficiency of group has greatly improved.
Centrifugal compressor of the present utility model be former on the basis of design by constantly putting into practice and studying
The product come, has done careful research and improvement to the everyway of unit so that the work efficiency of this product,
The service efficiency life-span is all greatly improved.Inter-stage of the present utility model is bled centrifugal compressor making user
