Description
Technical field
The present invention relates to a kind of end sealing device for compressor of turbosupercharger, belong to field of internal combustion engine.
Background technique
China's turbosupercharger industry has formed sizable scale through the development of decades.Turbosupercharger is as a new technology, promoted the development of internal-combustion engine, improved the technical performance of internal-combustion engine, be acknowledged as one of developing direction of internal-combustion engine, so far still keeping growth momentum in the ascendant, the particularly injection of new technology, as the back curved compressor impeller that leans forward, combined flow turbine, the calculating in ternary flow field and the breakthrough of turbine measurement of power equipment etc. are for the performance that improves turbosupercharger has been opened up wide prospect.Though turbosupercharger has obtained rapid raising at aspect of performance, at present, the sealing problem of turbosupercharger is still a weak link of turbosupercharger, the leakage of machine oil when mainly showing the pressurized machine running, how to reduce lubricating oil leakage and become the problem that each pressurized machine producer pays close attention to, the sealing configuration of turbosupercharger is to prevent that the lubricant oil in the middle case from entering the flow passage component of turbosupercharger, and the combustion gas of the air of prevention gas compressor end and turbine end enters the lubricant reservoir of pressurized machine, it is the important step that guarantees the turbosupercharger proper functioning, especially the working conditions change scope of vehicle turbocharger is bigger, when the axial force of pressurized machine was in bigger fluctuations state, the leakage that solves pressurized machine was difficult more.
As shown in Figure 1, at present, supercharger air compressor end sealing configuration generally comprises middle case 1, seal ring block set 3, thrust disc 4, thrust bearing 6, middle case 1, seal ring block set 3, thrust disc 4, thrust bearing 6 forms an oil pocket, be provided with circlip for hole 2 and O-ring seals 7 between middle case 1 and the seal ring block set 3, be provided with seal ring 5 between seal ring block set 3 and the thrust disc 4, lubricant oil enters from middle case 1 filler opening, enter thrust bearing 6 along oil duct, thrust bearing 6 two sides finish lubricated after, be thrown out of, lubricant oil in the thrust disc 4 is from the oil-sucking hole sucking-off, lubricant oil enters the return opening of middle case 1, discharges by self gravitation, and this sealing configuration is bigger in automobile-used turbo charged working conditions change scope, when the axial force of pressurized machine is in bigger fluctuations state, still some lubricant oil enters the gas compressor zone by seal ring 7 and seal ring 5, causes exhaust to emit blue smoke and oil consumption to increase, and sealing effect is undesirable.
Cause the reason of leakage to be divided into from mechanism: (1), be tightly connected gappedly comprises macroscopical gap or microcosmic gap; (2), there is pressure difference in both sides, the place of being tightly connected.
For preventing or reduce leakage that encapsulating method has following several at present:
(1), reduces the position that sealing is set as far as possible.This point is inflammable to handling, poisonous, strong corrosive medium is particularly important.
(2), obstruction or isolation.Various sealing gaskets, sealer, adhesive that static seal adopts just belong to this type of, can place obstacles in leakage way for motive sealing.
(3), draw or inject.Leak fluid is drawn resorption enter the room maybe and will inject closed chamber, stop the leakage of sealed fluid the harmless fluid of sealed fluid.
(4), the resistance in the increase leakage way.When fluid is made leakage flow in passage, can meet obstructions.Whether slot in the roughness of the pressure reduction at the size of resistance and passage two ends, the length of passage, wall and the passage etc. relevant, under the same pressure reduction, can add a lot of teeth to passage, or open various groove, the resistance of fluid when leaking to increase leaks thereby stop or reduce.
(5), in passage, set up the acting element.Because of setting up the acting element, the acting element causes back pressure to leakage fluid during work, and offset pressure is poor, stops dielectric leakage.Centrifugal seal, spiral seal promptly belong to this type of.
