Description
Technical field
It is a kind of monoblock type stator blade of centrifugal compressor the utility model relates to arrive centrifugal compressor field.
Background technique
Centrifugal compressor belongs to the universal machine in the development of the national economy, has a wide range of application, and quantity is more, consumes a large amount of energy
Source.With the development of economy with the demand of industry, multistage centrifugal compressor is using increasingly extensive.In the master of multistage centrifugal compressor
It wants in passage component, there is a large amount of energy losses for diffuser, bend and return channel.With certain vertical subdivision type multistage centrifugal pressure
For the intergrade of contracting machine, when gas flows through diffuser, bend and return channel, there are up to 15.13% flow losses.Cause
This, improves the design of stationary parts between compound compressor grade, develops efficient blade, is that the current compressor industry in China is badly in need of
One of key technology of solution is conducive to improve China's compressor design technology, improves competitiveness, has simultaneously for energy-saving and emission-reduction
There is major and immediate significance.
When between stationary parts is studied compressor stage, scholars are generally concerned with the design of each separate part, and
Diffuser, bend and return channel are not studied as a whole.Traditional " impeller+diffuser vane+return channel leaf
Piece " or the structure type of " impeller+return channel blade " cannot guide gas since corner does not install blade well here
Body flowing, the chaotic air-flow come out from bend can make return channel inlet air flow uneven, or even the stall of air-flow and whirlpool occur
Whirlpool phenomenon, to influence whole grade compressor efficiency.It therefore, being capable of correct guidance gas stream by the design of monoblock type stator blade
It is dynamic, it improves efficiency, reduces loss, be very necessary.
Utility model content
The utility model is intended to design a kind of novel monoblock type stator blade, and the blade is through diffuser, bend and returns
Flow device runner.For improved monoblock type stator blade, good guiding function is played to air-flow in entire flow process, is had
The diffusion process for controlling to effect air-flow, reduces loss, energy saving.
The technical solution of the utility model includes:
A kind of monoblock type stator blade of centrifugal compressor is connected on the outside of the monoblock type stator blade 4 with screw rod 5 by partition 6,
And it is realized and is fixed by screw rod 5 and casing；The front end of monoblock type stator blade 4 is connected with the rear end of impeller 3, impeller 3 and 1 phase of main shaft
Even, and its rotation is made by motor；The both sides external of impeller 3 installs labyrinth seal structure 2 respectively, for preventing letting out for gas
Leakage.
The stagger angle of the monoblock type stator blade 4 is 62 °, vane thickness 9mm.
The design parameter of the monoblock type stator blade 4 includes: that the number of monoblock type stator blade 4 is 10, revolving speed 0, into
Mouth diameter is 750mm, and entrance width 31.2mm, curve inner side arc radius is 18mm, and bend outer arc radius is
49.12mm, outlet average diameter are 466mm, and outlet mean breadth is 56.53mm.
The design parameter of the impeller 3 includes: that the number of blade of impeller 3 is 13, revolving speed 8129rpm, and impeller inlet is flat
Equal diameter is 326.54mm, and impeller outlet diameter is 600mm, exit width 39mm.
The utility model has the beneficial effects that the monoblock type stator blade of the utility model design can not only improve compressor and set
The pneumatic efficiency of enumeration improves pressure ratio, while also having widened the steady working condition of compressor, has achieved the purpose that energy saving.

Specific embodiment
The technical solution of the utility model is further detailed below in conjunction with specific embodiments and the drawings.
A kind of monoblock type stator blade of centrifugal compressor, in Fig. 1, impeller 3 is connect with main shaft 1, makes its rotation by motor
Turn, energy is provided.It is respectively provided with labyrinth seal structure 2 in the two sides of impeller 3, prevents the leakage of gas.Behind impeller 3
Monoblock type stator blade 4 is connected, monoblock type stator blade 4 is fixed by partition 6.Screw rod 5 is installed, and fixed by screw rod 5 on partition 6
In casing.
After electric motor starting, with 1 high speed rotation of main shaft, gas is flowed in impeller 3 by rotary centrifugal force and diffusion impeller 3
Effect, after being come out by impeller 3, the gas of high speed flows into monoblock type stator blade 4.With the increase of diameter, flow area increases,
Gas flows in monoblock type stator blade 4, and air velocity slows down, and pressure is improved.In entire flow process, monoblock type is quiet
Blade 4 plays good guiding function to air-flow, has efficiently controlled the diffusion process of air-flow, reduces loss, improves compression
Engine efficiency.
62 ° of the stagger angle of monoblock type stator blade 4, vane thickness 9mm.Remaining design parameter and service condition are according to table
Described in 1, meridian plane structure chart is referring to Fig. 5.
The geometric parameter of table 1 impeller and monoblock type stator blade
By taking the intergrade of certain vertical subdivision type multistage centrifugal compressor as an example, gas flows through impeller 3 and monoblock type stator blade 4
Afterwards, flow losses reduce, and whole stage efficiency is promoted.
