Abstract
Turbo charger compressor end seal cover, including the seal cover, its suit is on the rotor shaft, and one end is the A end with the impeller contact, and the B end of the other end for being close to the bearing body is held from A and be equipped with oblique angle disc and middle disc in proper order on the outer fringe face of B end, is equipped with the first oil groove that gets rid of between oblique angle disc and the middle disc. The utility model has the advantages that, anti negative pressure can the reinforce, reduces turbo charger's oil leak fault rate. The one end that the seal cover is being close to the impeller is equipped with the oblique angle disc, be equipped with annular sloped surface on the oblique angle disc, this annular sloped surface and the annular sloped surface of oil seal cover centre bore opening part cooperate, form the awl annular gap of opening towards the B of seal cover end, when the rotor shaft rotates, the long -pending fluid of staying among the awl annular gap can be faced the one end of keeping away from the impeller and throw away, can not flow back to once more among the awl annular gap, no fluid is long -pending among the awl annular gap stays the nature not have fluid to permeate to the sealing washer department between seal cover and the oil seal cover, effectively prevent the oil leak.
Description
Technical field
The utility model 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 purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of turbocharger air compressor end stuffing box gland.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.
The technical solution of the utility model 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 utility model is: oblique angle disc is provided with annular slope on the end face near A end side.
The utility model 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 utility model 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 utility model further technological scheme is: the shaft axis m angle a of annular slope and stuffing box gland endoporus is 35 ~ 55 °.
The utility model further technological scheme is: a=45 °.
The utility model 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 utility model is further described.
