Abstract
A compressor end sealing sleeve of a turbocharger comprises a sealing sleeve, wherein the sealing sleeve is mounted on a rotor spindle in a sleeving manner, one end of the sealing sleeve serves as an end A in contact with an impeller, the other end of the sealing sleeve serves as an end B close to a bearing body, a bevel angle oil flinger and a middle oil flinger are arranged on a peripheral surface from the end A to the end B in sequence, and a first oil flinger is arranged between the bevel angle oil flinger and the middle oil flinger. The compressor end sealing sleeve of the turbocharger, provided by the invention, has the advantages that negative pressure resisting capability is strong, and the oil-leakage malfunction rate of the turbocharger is lowered. A bevel angle oil flinger is arranged at one end, close to the impeller, of the sealing sleeve, an annular inclined plane is arranged on the bevel angle oil flinger, the annular inclined plane is matched with the annular inclined plane at the opening part of the center hole of an oil sealing cover, a conic ring gap with an opening facing to the end B of the sealing sleeve is formed, during the rotating of the rotor spindle, oil fluid accumulated in the conic ring gap can be thrown away towards one end far away from the impeller, back flowing to the conic ring gap again can be prevented, since no oil fluid is accumulated in the conic ring gap, no oil fluid can permeate to the position of a sealing ring between the sealing sleeve and the oil sealing cover naturally, and oil leakage can be effectively prevented.
Description
Technical field
The present invention relates to the sealed member of turbocharger air compressor end, particularly turbocharger air compressor end stuffing box gland.
Background technique
Turbocharging technology popularizes use in an all-round way at diesel engine realm, and it is one and the dump energy in engine exhaust is converted into the technology of effective engine power.This technology not only can improve the power character of motor, improve the fuel economy of motor, can also reduce the harmful components in motor discharging waste gas, has energy-saving and environmental protection effect.
Along with development and the progress of supercharging technology, and the seal request of terminal use to pressurized machine is more and more higher, market is fed back pressurized machine oil leakage fault phenomenon to get more and more, and develop rapidly that the oil-leakage-prevention performance requirement of petrol engine supercharging technology to pressurized machine is higher in the recent period.
The rotating speed of motor pressurized machine when idling and low speed and load is all lower, and now wheel backface can form negative pressure state, more easily oil leakage fault occurs.
Existing compressor end sealing structure of turbosuperchargers as shown in Figure 1, comprise oil sealing cap 10 and stuffing box gland 20, stuffing box gland 20 is sleeved on axle 30, its one end is provided with disc 201, oil sealing cap 10 is sleeved on stuffing box gland 20, itself and seal respectively by seal ring between compressor housings 40 and oil sealing cap 10.
The deficiency of this structure is, the oil that stuffing box gland 20 disc 201 throws away spatters on oil sealing cap 10 end face, flow in the gap 70 between oil sealing cap 10 and stuffing box gland 20, when axle 30 rotates, can flow back in gap 70 along the end face of oil sealing cap 10 again after fluid in gap 70 throws away, make there is lubricant oil all the time in gap 70, under negative pressure state, fluid easily infiltrates into seal ring place by gap 70, and then leaks into impeller end.Namely there is leakage of oil hidden danger in the structure of sealing cover, and anti-negative pressure ability is low.
The method of the above-mentioned Leakage of solution common is at present, reduces the gap between oil sealing cap and stuffing box gland, increases the quantity of seal ring between oil sealing cap and stuffing box gland.But therefore need to improve part accuracy of manufacturing, add cost of production, and cause pressurized machine part when high speed operation easily to wear and tear.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of turbocharger air compressor end stuffing box gland is provided.It solve existing turbocharger air compressor end stuffing box gland and under negative pressure state, there is leakage of oil hidden danger, the problem that anti-negative pressure ability is low.
Technological scheme of the present invention is: turbocharger air compressor end stuffing box gland, comprise stuffing box gland, it is sleeved on rotor shaft, one end is that the A contacted with impeller holds, the other end is hold near the B of bearing support, to the outer edge surface of B end, be provided with oblique angle disc and middle disc from A end successively, be provided with first between oblique angle disc and middle disc and get rid of oil groove.
The further technological scheme of the present invention is: oblique angle disc is provided with annular slope on the end face near A end side.
The present invention further technological scheme is: stuffing box gland is held on the outer edge surface of end at B and is provided with end disc, is provided with second and gets rid of oil groove between end disc and middle disc.
The present invention further technological scheme is: the both sides end face of end disc and middle disc is all perpendicular to the shaft axis m of stuffing box gland endoporus.
The present invention further technological scheme is: the shaft axis m angle a of annular slope and stuffing box gland endoporus is 35 ~ 55 °.
The present invention further technological scheme is: a=45 °.
The present invention compared with prior art tool has the following advantages:
1, anti-negative pressure ability is strong, reduces the oil leakage fault rate of turbosupercharger.Stuffing box gland 1 is provided with oblique angle disc 11 in the one end near impeller 3, oblique angle disc 11 is provided with annular slope 111, this annular slope 111 matches with the annular slope of oil sealing cap 5 center hole opening, form the conical ring gap 6 that opening is held towards the B of stuffing box gland 1, when rotor shaft 2 rotates, the fluid accumulated in conical ring gap 6 can throw away towards the one end away from impeller 3, can not again flow back in conical ring gap 6, accumulating nature without fluid in conical ring gap 6 does not have fluid to infiltrate into seal ring place between stuffing box gland 1 and oil sealing cap 5, effectively prevents leakage of oil.
2, stuffing box gland is provided with end disc in the end that B holds, and is provided with second and gets rid of oil groove between itself and middle disc.End disc, middle disc and second get rid of oil groove and match, and can get rid of in the shoe cream room of bearing support by fluid, prevent the seal ring place between fluid inflow stuffing box gland and oil sealing cap, effectively prevent leakage of oil.
3, the seal groove on stuffing box gland, oblique angle disc, end disc and middle disc match and play multi-sealed effect.
Below in conjunction with figure and embodiment the invention will be further described.
