K102 Hydrogen Circulation Centrifugal Compressor Floating Ring Seal Transformation

The application in the chemical machinery field of petroleum of fluid seal is very extensive, mechanical spare part which says to be indispensable. It is of great impact in the safety of production for the right whole machinery equipment, the whole set of device, even to the whole factory. In enterprises of petrochemical industry, the ones that deal with liquid or gaseity most of body have corrosivity, flammability, explosive and toxicity. Once seal and lose efficiency, the medium is let out, the consequence is too ghastly to contemplate. So develop fluid sealed technology turn round to equipment reliable, the aircrew is safe and steady, the device produces and plays a quite important role in succession.The floating seal ring is moved and is a kind of sectional fluid with more special structure, because its sealing property is steady, it can be used in high temperature, high pressure and rotate the mechanical advantage of fluid at a high speed, the centrifugal gas compressor sending flammable and explosive medium, such as oil gas, hydrogen. So it adopt the ring of floating to be sealed more at present. This text float to circulation hydrogen at odds with the community or the leadership compressor ring seal the question of leaking appeared promptly, and a series of theories are calculated through an analysis of its structure and operation conditions, find out and seal the invalid reason, pass the actual operating mode and test again, draw the relation among the pressure, rotational speed and relative eccentricity, and has improved according to these data structure and material with sealed ring to floating. Practice has proved, this transformation reached the anticipated technological result and economic indicator .
