Coordinate assembling, for spiral case with being sealed at impeller cover cooperation with soft seal, the back side outside vaned diffuser with impeller is equipped with hermetic seal
Device seals, and hermetic seal device is divided into sealer and lower sealer two parts, and hermetic seal device is the Comb Labyrinth Seals with broach, increases
Fast case and high speed axis connection, fastened after key connection is used between high speed shaft and impeller by pull bar and round nut cooperation.
Further, the gearbox is horizontal midsplit type gearbox.
Further, adpting flange uses hollow integral transition adpting flange.
Further, hermetic seal device, which is provided with, fills steam port.
Further, spiral case at impeller cover cooperation with soft seal with being sealed.
Further, fixed after coordinating key connection using two symmetrical keys between high speed shaft and impeller through round nut.
Further, impeller material uses titanium alloy, and remaining steam excessively stream part of compressor uses stainless steel.
Further, impeller is radial direction semi-open type three-dimensional flow impeller.
To sum up, above-mentioned technical proposal of the present utility model has the beneficial effect that：

Embodiment
Feature of the present utility model and principle are described in detail below in conjunction with accompanying drawing, illustrated embodiment is only used for explaining
The utility model, the scope of protection of the utility model is not limited with this.
As shown in figure 1, adpting flange 3 is connected with horizontal midsplit type gearbox 1, adpting flange 3 uses hollow integral transition
For connecting flange structure as shown in Fig. 2 expanding housing and gearbox space, neither destroying in the level of gearbox can be most under separation structure
Big protection gearbox, it is for convenience of hermetic seal device disassembling, assembling and replacing using hollow type；Spiral case 7 is on adpting flange 3 and with having
Leaf diffuser 6 and impeller cover 11 coordinate installation, and spiral case 7 has leaf diffusion with being sealed at the cooperation of impeller cover 11 with soft seal 12
Hermetic seal device 5 is equipped with outside device 6 to seal the back side of impeller 8, ensure that the air-tightness of steam.Because MVR centrifuges vapour pressure
Contracting machine medium is that vapor has corrosivity, so in addition to impeller material uses titanium alloy (TC4), remaining excessively stream part of compressor
Use stainless steel.
Impeller 8 is the efficient radial direction semi-open type three-dimensional flow impeller of designed, designed, is designed using the small angle of outlet, improves impeller
Efficiency, processed using titanium or two phase stainless steel solid forging milling；Connected between impeller 8 and high speed shaft 2 with two symmetrical keys
Fixed after connecing through round nut as shown in figure 1, dismounting impeller is more convenient without specific purpose tool, units' installation maintenance.High speed shaft 2 and gas
Axle sleeve 4 is provided between sealer 5 and vaned diffuser 6.
Diffuser 6 is vaned diffuser, is formed with stainless steel entirety milling, and steam flows out warp in the impeller of high speed rotation
Vaned diffuser is crossed, its flow area progressively increases, and vapor (steam) velocity gradually reduces, and pressure just increases, and reaches vapor (steam) temperature rise
Purpose.
As shown in Figure 3 and Figure 4, hermetic seal device 5 is autonomous Design Comb Labyrinth Seals, and hermetic seal device 5 divides for upper sealer
51 and lower two parts of sealer 52, hermetic seal device 5 be the Comb Labyrinth Seals with broach 53.It is additionally provided with hermetic seal device 5 and fills steaming
Steam ports 54.The characteristics of binding medium and higher linear velocity, while considered in fan design and filled steam-tight needs,
And after steam condensation cooling water discharge problem, the Comb Labyrinth Seals that the mutual intersection of designed, designed tooth is placed, in fanman
When making, because system is subnormal ambient, the vapor being passed through reaches balance by the decompression step by step of Comb Labyrinth Seals, so as to rise
To sealing function.The novel labyrinth seal divides external structure as shown in figure 3, being not required to dismantle any parts such as impeller, spiral case in being,
Sealing can directly be changed.The higher carbon ring seal of the alternative price of Comb Labyrinth Seals, manufacturing cost is reduced, it is competing to improve equipment
Strive power.
Above-described embodiment is only the description carried out to preferred embodiment of the present utility model, not to the model of the present invention
Enclose and be defined, on the premise of the utility model design spirit is not departed from, relevant technical staff in the field is to the utility model
Various modifications and improvement, all should expand determined by the utility model claims book in protection domain.
