Description
Technical field
The utility model is related to a kind of vapour compression machine field, more particularly to a kind of sealing gland for vapour compression machine.
Background technology
Vapour compression machine is the key equipment of raising vapor (steam) temperature and pressure in MVR vapo(u)rization systems.In MVR vapo(u)rization systems
In, vapour compression machine realizes that the indirect steam in MVR systems is recompressed as core component, lifts the pressure and temperature of indirect steam
Degree, then enters back into heated material in heat exchanger, reaches the purpose for saving raw steam.Its operation principle is by running at high speed
Impeller, improves the pressure and temperature of steam.
In vapour compression machine, it is desirable to which the steam of internal compression and ambient atmosphere are completely cut off, the sky in air is prevented
Gas is mixed into the steam by compressor compresses, and this allows for needing progress gas close between vapour compression machine and gear-box
Envelope, so as to realize the isolation of outside air and steam inside, current most common way is labyrinth seal+gas-flow closure or carbocyclic ring
Its seal clearance of sealing+gas-flow closure, wherein labyrinth seal is than larger, so that poor sealing performance, although and carbocyclic ring sealing property
Good but expensive, cost is high.
Utility model content
Utility model purpose：To solve the defect of prior art, a kind of sealing gland for vapour compression machine is now provided, it is comprehensive
The advantage and disadvantage of carbon ring seal and labyrinth seal, its rational deployment is optimized, while being improved design to air seal structure so that whole
Not only sealing property is met the requirements individual air seal structure, and cost is reduced, and effectively prevents outside air from entering in vapour compression machine
Portion, while also reducing the consumption of sealed steam.
Technical scheme：A kind of sealing gland for vapour compression machine described in the utility model, including it is fixedly mounted on steam
Sealing gland on the inside of compressor scroll, it is sleeved on the outside of high speed shaft, and laterally middle to have annular steam aeration tank, the annular is steamed
Have between vapour aeration tank and sealing gland inner chamber in the filling channel of a plurality of insertion, sealed steam feeding annular steam aeration tank and pass through
A plurality of filling channel enters sealing gland inner chamber and forms vapor barrier face, and sealing gland inner chamber is divided into outside（Nearly atmospheric side）With inner side
（Nearly compressor side）, multiple carbocyclic rings are installed in the inner chamber of outside, and multiple broach are installed in the inner chamber of inner side, the sealing gland it is outer
Side is provided with bleed outlet, is easy to discharge condensed water and unnecessary sealed steam.
Preferably, the installation gap of the carbocyclic ring is 0.03 ~ 0.05mm.
Preferably, the installation gap of the broach is 0.15 ~ 0.5mm.
Preferably, the sealing broach has larger gap with high speed between centers, be not in that wiping is touched during compressor operating
Abrasion, will not bring impurity into, it is ensured that the clean level of unit medium into the sealed steam in compressor.
A kind of sealing gland for vapour compression machine disclosed in the utility model, it is applied on vapour compression machine, due to
It is compressed steam in vapour compression machine, the effect of sealing gland is to realize that compressed steam completely cuts off with outside air, the utility model structure
Middle comprehensive using carbocyclic ring and broach combination steam seal, carbocyclic ring is arranged on into outside effectively to prevent outside air from entering gas
Envelope, is leaked out while being also possible to prevent sealed steam, in inner side using broach as sealing structure, due to sealed steam and pressure
Contracting vapor quality is identical, thus sealed steam enter unit in will not produce big influence, this combined structure both ensure that close
Sealing property also assures that economic performance, and the structure to sealing gland seat is improved optimization in addition so that carbocyclic ring is close after being installed with broach
Sealing property is improved compared to itself.
Beneficial effect：A kind of sealing gland for vapour compression machine disclosed in the utility model, is ensureing that sealing gland is preferably close
On the premise of envelope property, reduce the cost of sealing itself and effectively reduce the consumption of sealed steam in unit running process.
