Description
Technical field
The utility model belongs to gas centrifugal blower fan technical field, and in particular to a kind of anti-leak knot of gas centrifugal blower fan
Structure.
Background technology
Can gas centrifugal blower fan plays a very important role in steel production, because ensure it for a long time, stably
Operation is related to the production efficiency of iron and steel enterprise, meanwhile, whether coal gas axial flow fan has the leakage of gas medium in operation,
Be weigh its operation whether safety important examination item because gas centrifugal blower fan in process of production once occur high concentration
The leakage of gas medium, steel plant produced on-site personnel and all working equipment will be caused to be among being in extreme danger.
However, the seal form and its sealing position of encrypting packing that current gas centrifugal blower fan is traditional, its anti-leak
Effect is not highly desirable, and sealing gasket aging speed is fast, it is often necessary to which maintenance is changed, and is caused the time between overhauls(TBO) and very short is asked
Topic.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of good sealing effect, maintenance week
The leakage-proof structure of the gas centrifugal blower fan of phase length.
The technical problem that above-mentioned utility model solves is achieved through the following technical solutions, a kind of gas centrifugal blower fan
Leakage-proof structure, it is flexible coupling including air inlet, casing inlet box air inlet faying face, casing inlet box subdivision faying face, goes out
Air port is flexible coupling, faying face, the casing inlet box of diffuser pipe air outlet faying face, diffuser pipe, casing inlet box and diffuser pipe
And blower fan main shaft, it is characterized by, and blower fan main shaft passes through from casing inlet box, penetrates part and extension is respectively arranged with
Carbon ring seal component；Casing inlet box subdivision faying face, casing inlet box air inlet faying face, diffuser pipe air outlet faying face,
The faying face of casing inlet box and diffuser pipe is machined with seal groove respectively, and the sealing strip for being higher by notch is pressed into seal groove；Casing
Subdivision faying face, casing inlet box air inlet faying face, diffuser pipe air outlet faying face, casing inlet box and the diffusion of inlet box
The faying face of pipe all reaches roughness requirements by finishing and sealed with the fluid sealant of heat resisting and pressure resisting.
Include seal casinghousing as preferable, described carbon ring seal component, three and blower fan master are equipped with seal casinghousing
The graphite-seal ring that axle is close to, hoop entertains holddown spring on per pass graphite-seal ring, and holddown spring is fixed by pin, seal casinghousing
Inside it is additionally provided with and is periodically filled with the lubricant grease entrance of lubricating grease and is persistently filled with the nitrogen inlet of nitrogen.
The utility model has the advantages that compared with prior art：Because hoop entertains pressure on per pass graphite-seal ring
Tight spring, holddown spring are fixed by pin, make it not with main axis, if graphite-seal ring has abrasion, pass through the pressure of holddown spring
Clamp force, can continuous aweather owner's shaft compression, ensure that sealing effectiveness., can be significantly to being periodically filled with lubricating grease in carbon ring seal
Extend the life-span of graphite carbon ring component, and nitrogen is persistently filled with to carbon ring seal component, air pressure can have higher than the nitrogen of coal gas
The prevention gas leak of effect, so as to strengthen sealing effectiveness；Each faying face is machined with seal groove respectively, and press-in is higher by sealing groove mouth
Sealing strip, then sealed in each faying face using the fluid sealant of heat resisting and pressure resisting, the effect of such dual-seal is obviously eager to excel
In the sealing of prior art sealing gasket, so as to reach preferable anti-leak result.
