Abstract
The utility model relates to an air-tight sealing body of a chilling gas compressor, comprising a sealing body and a sealing surface; a double dovetail groove matching structure is adopted at the intersecting position of the sealing body and the sealing surface, and labyrinth teeth are arranged on a shaft sleeve of the sealing body. The labyrinth teeth are processed on the shaft sleeve and the sealing body and the sealing surface are planes; when the shaft runs out, the labyrinth teeth of the shaft only can produce local friction to the sealing body for further forming labyrinth and reducing leakage; the material of the sealing surface is changed into polyether-ether-ketone, and the planes of the sealing body and the sealing surface are changed into double dovetail groove matching structure, thus effectively preventing the sealing material from being dropped off.
Description
Technical field
The utility model relates to a kind of conveying burn into high temperature media, the used seal of high rotating speed single-stage centrifugal compressor.
Background technique
Be used to carry its fed sheet of a media of Quench air compressor of synthetic gas to have characteristics such as burn into high temperature in the fine coal gasification process, and unit rotating speed after speedup is higher, reaches 10500r/min.Its seal comprises parts such as shaft end seal, wheel cover gas seal, Balance disc sealing gland, sealing gland.Wherein seal body material design material is an aluminum alloy, and the sealing surface designing material is Mo, Si, Ni, A1 and graphite mixture.This unit is after operation after a while, and the burn into obscission appears in seal, and loses efficacy gradually, causes a large amount of synthetic gas to leak, and directly causes production system to be stopped.Former sealing labyrinth teeth design is on seal, and during the rotor high-speed running, it is beated and will cause the sealing surface wear of whole seal, thereby causes seal clearance excessive; Seal and sealing surface are Plane intersects, and the phenomenon that sealing material comes off is more serious, and after long-time wearing and tearing, seal failure is about 25 days because of seal failure causes the average life cycle of this unit mutually.
Summary of the invention
The purpose of this utility model provides a kind of Quench air compressor seal that makes Quench air compressor long-period stable operation.
The purpose of this utility model is achieved in that a kind of Quench air compressor hermetic seal body, comprises seal and sealing surface, and seal and sealing surface intersect locates to be adopted as the double swallow tailed groove cooperating structure, and the axle sleeve of seal is provided with labyrinth teeth.The material of seal changes to the 316L stainless steel.The sealing surface material is a polyether-ether-ketone.
Quench air compressor hermetic seal body provided by the utility model labyrinth teeth is processed on axle sleeve, and the seal sealing surface is the plane, and when axle was beated, the labyrinth teeth of axle only can produce concentrated wear to seal, and further forms the labyrinth, reduced and revealed; With the material of seal is the 316L stainless steel, and this material has characteristics such as wear-resisting property is good, corrosion-resistant, is applicable under abominable working environments such as burn into high temperature to move.Change the sealing surface material into polyether-ether-ketone, seal is combined with the plane of sealing surface change the double swallow tailed groove cooperating structure into, the phenomenon of effectively having avoided sealing material to come off simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an axle sleeve structure schematic representation of the present utility model.
Embodiment
Structure of the present utility model comprises seal 1 and sealing surface 2 as depicted in figs. 1 and 2, and seal 1 and sealing surface 2 intersect locates to be adopted as double swallow tailed groove and join 5 and close structure, and the axle sleeve 3 of seal 1 is provided with labyrinth teeth 4.The material of seal 1 seal changes to the 316L stainless steel.Sealing surface 2 materials are polyether-ether-ketone.
Labyrinth teeth 4 is processed on axle sleeve 3, and the seal sealing surface is the plane that when axle was beated, 4 of the labyrinth teeths of axle can produce concentrated wear to seal 1, and further formed the labyrinth, reduced to reveal; The material of seal is changed to the 316L stainless steel, and this material has characteristics such as wear-resisting property is good, corrosion-resistant, is applicable under abominable working environments such as burn into high temperature to move.Change the sealing surface material into polyether-ether-ketone.Simultaneously seal is combined with the plane of sealing surface by double swallow tailed groove 5 and cooperate the phenomenon of effectively having avoided sealing material to come off.
