The utility model relates to a kind of centrifugal compressor more particularly to a kind of vertical centrifugal compressor axial balancing devices.
Background technique
Centrofugal compressor structure is complicated, common horizontal arrangement.For certain particular applications, special construction requirement
Vertical centrifugal compressor, can axial force size relation to unit normally, reliably operate.
Attached drawing 1 is referred to, the centrifugal compressor unit of the prior art is single-stage cantilever arrangement, and impeller 1 is relatively large in diameter, rotor
Revolving speed is 4000rpm, and the shroud entrance of impeller 1 is disposed with impeller inlet axial seal 4, prevents the leakage current of gas.Work as unit
When running at high speed, unit generates downward axial force, if cannot balance well, will cause unit that can not operate.
Summary of the invention
The purpose of this utility model is to provide a kind of vertical centrifugal compressor axial balancing devices, can effectively solve vertical
The excessive problem of centrifugal compressor axial force guarantees that unit is normal, reliably operates.
The utility model is realized in this way:
A kind of vertical centrifugal compressor axial balancing device, the impeller including impeller and setting Pan Jinkouduanchu before the impeller
Import axial seal；The vertical centrifugal compressor axial balancing device further includes the radial seal of impeller hub disk and impeller front disc
Radial seal；Impeller hub disk radial seal is fixed at the hub disk outlet end of impeller, on the part of upper impeller, after impeller
Hub disk chamber is formed between disk radial seal, impeller hub disk and the upper parts of impeller；Impeller hub disk runs through equipped with several
Hole, several through holes and hub disk chamber；Impeller front disc radial seal is fixed at the shroud outlet end of impeller, is located at leaf
On the part for taking turns lower part, shroud chamber, shroud are formed between impeller front disc radial seal, impeller front disc and the lower part of impeller
Chamber is connected to by through-hole with impeller front disc outlet end.
The axial direction of several through holes is axial parallel with impeller.
Several described through holes are uniformly distributed along the circumferential direction of impeller.
The utility model compared with prior art, has the following beneficial effects:
1, the utility model hub disk chamber can obviously reduce axial force, while shroud chamber pressure is significantly greater than hub disk chamber
Room, by the combination of hub disk chamber and shroud chamber, introduces impeller outlet gas to further decrease unit axial force
To shroud chamber, meet limitation requirement of the vertical compressor unit to axial force.
2, the utility model increases radial seal structure, and radial seal structure belongs to static element, is easy to install and remove.
The utility model can effectively solve vertical centrifugal compressor by forming impeller hub disk chamber and impeller front disc chamber
The excessive problem of axial force provides method simple to operation for Practical Project, guarantees that unit is normal, reliably operates.
Detailed description of the invention

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
It refers to attached drawing 2, a kind of vertical centrifugal compressor axial balancing device, including impeller 1 and is arranged in 1 shroud of impeller
Impeller inlet axial seal 4 at input end；Vertical centrifugal compressor axial balancing device further includes impeller hub disk radial seal 2
With impeller front disc radial seal 3；Impeller hub disk radial seal 2 is fixed at the hub disk outlet end of impeller 1, is located at 1 top of impeller
Part on, between impeller hub disk radial seal 2, impeller hub disk 101 and the upper parts of impeller 1 formed hub disk chamber P1；Leaf
It takes turns hub disk 101 and is equipped with several through holes 11, several through holes 11 are connected to hub disk chamber P1；Impeller front disc radial seal
3 are fixed at the shroud outlet end of impeller 1, on the part of 1 lower part of impeller, impeller front disc radial seal 3, impeller front disc
Shroud chamber P2 is constituted between 102 and the lower part of impeller 1, shroud chamber P2 is connected by through-hole 5 and 1 shroud outlet end of impeller
It is logical.
The axial direction of several through holes 11 is axial parallel with impeller 1, can reduce axial force.Described several
Through hole 11 is uniformly distributed along the circumferential direction of impeller 1, is conducive to dynamic balance of impeller.
In circumferentially through hole 11 of impeller 1, and impeller hub disk radial seal 2 is arranged on disk 101 after the impeller, is formed
Hub disk chamber P1 reduces axial force；In the shroud exit of impeller 1, arrangement impeller front disc radial seal 3, entrance arrange impeller
Import axial seal 4, the shroud chamber constituted between impeller front disc radial seal 3, impeller front disc 102 and the lower part of impeller 1
Room P2 is sealing structure, and 1 exit gas of impeller is introduced shroud chamber P2 by the through-hole 5 on 1 lower part of impeller, thus into
One step reduces axial force, meets limitation requirement of the vertical compressor unit to axial force.
