The triturate of the super-speed centrifugal in oxo process compressor dry air hermetic seal ing and appliance summaryAlong with the chemical engineering of oil and technical evolution in energies, the occupation parameter of the centrifugal compressor of the conduct and actions heart fraction is more and more high, the compression crankshaft for request that seal is too more and more strict. The concept of the dry air hermetic sealing is a foundation that 60' s develop up from the smooth plain besring in gas in last phase of, among them with the spiral slot hermetic sealing is most for typical model. Research that through few yearses, The United States John Crane leads off to release to fuck the air hermetic sealing product union devotion indrstry usage. Practice the enunciation, fuck the air seal completely at very in many ways and all superior seal completely in the common contact quinonoid formula machine, it used for the pipe line, ocean platen, oil refinery, oil chemical engineering iso - vocation primarily, suiteding for the system of any feed gas. Because of dry air hermetic sealing fall under non-contacting mechanical seal, worth restriction enzymes in basic upper not summit to PV, therefore fuck the air hermetic sealing to suit the large centrifugal compression crankshaft that be used as specially to under the super-speed high pressure condition seal. The presence of the dry air hermetic sealing, is hard nut to crack that hermetic sealing technical once revolution, gas hermetic sealing from now on can settle, but is no longer lubricated by hermetic sealing butyraceous restriction enzymes.The oil system of its a gas for needing grasp system ratio contact quinonoid formula hermetic sealing wants to get the polypeptide in brief. Moreover, the presence of the dry air hermetic sealing also changed traditional the idea of hermetic sealing;Will fuck the air hermetic sealing technique to seal completely with pinning the principle organism combine, acting for the traditional" liquid seal air or the liquid of 1 iquid seals'' idea with the new ideas of the " the liquid of air seal or air seal airs", canning secure any hermetic sealing medium realizes the null diverts, this make fuck the air seal completely at pump to seal the realm with the axis to also will have the extensive and applied foreground.Dry air hermetic sealing from revolution cyclo -, stat cyclo -, spring coil, hermetic sealing ring and spring coil mount and axis set constitutive enzyme. The dry air hermetic sealing revolution cyclo - hermetic sealing face handles through lapping, burnishing, combining to is above it the face process the fluid dynamical pressure slot that have the special action. When the dry air hermetic sealing revolution cyclo - revolve, the hermetic sealing gas were inhaled the dynamical pressure slot inside, from outside diameter toward centre, the weight of radial towards the hermetic sealing weir flows. Because the hermetic sealing weir reduces expenses the action, the gas of the entry hermetic sealing face is compressed, the gas press goes up. Under the press' action, the hermetic sealing face were pushed away, the flowing gas becomes in two hermetic seal ings face a very thin air in lay membrane, the air' s membrane implementation hermetic sealing action.
