Description
Technical field
This utility model belongs to the technical field of compressor, is related specifically to add at inter-stage in chemical technology field
Gas, with traffic requirements at different levels after meeting, meets a kind of inter-stage aerating centrifugal compressor of customer process.
Background technology
Centrifugal compressor is widely used in petrochemical industry, metallurgical industry and other industrial technology as pneumatic machinery
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).Described lead 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 product some aspect also have
The leeway improved, especially needs to require supplementation with gas during compressed gas and meets use during compressed gas
The production requirement at family.Active wheel (i.e. impeller) on the critical piece of product i.e. rotor and rotor, also compressor
Sealing device, all manifold research such as shape of casing, by the work efficiency of in-depth study product,
Save maintenance cost, and work scope all can significantly promote.To sum up these we study work just
The starting point made.
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 of inter-stage aerating, the gas i.e. entered in compressor inlet can not meet customer requirement after compression,
This is accomplished by adding an air intake cylinder air inlet to meet a kind of centrifugal compressor of the technological requirement of user at inter-stage.
This utility model provides a kind of inter-stage aerating 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, the upper shell sealing by two ends from the horizontal plane of rotating shaft
Body fixes with lower house；
(2) lower house of compressor is fixed on bearing, is front and back provided with inlet, outlet below, and centre sets
There is the air intake cylinder of an aerating；
(3) part such as impeller, spacer, balancing frame, thrust disc is arranged on main shaft the weight forming compressor
The parts wanted, i.e. rotor, rotor is placed on lower house by bearing and bearing block.
The size of the impeller on inter-stage aerating centrifugal compressed machine rotor of the present utility model is two kinds, aerating air intake cylinder
Before for large-size, afterwards be less impeller, such design can improve the work efficiency of this product；
The impeller of inter-stage aerating centrifugal compressor of the present utility model uses rustless steel double shrouded wheel, and blade is adopted
By the blade shape of palintrope structure, compared with the unshrouded impeller of other products, the whole efficiency of unit has significantly
The lifting of degree.
Inter-stage aerating centrifugal compressor of the present utility model be former on the basis of by constantly putting into practice and studying
And the product designed, the everyway of unit is done careful research and improvement so that the work of this product
