Abstract
The invention provides an arrangement structure of turbocharger sealing rings. The arrangement structure comprises a compressor back plate, a shaft sealing sleeve, two sealing rings, a lubricating oil guide hole, an oil return chamber and a center shaft, wherein the shaft sealing sleeve is arranged on the outer circumference of the center shaft; the compressor back plate is arranged on the outer circumference of the shaft sealing sleeve; the sealing rings are arranged on the contact surface of the shaft sealing sleeve and the compressor back plate; the lubricating oil guide hole is formed in the compressor back plate, is formed between the sealing rings, and is connected with the oil return chamber; and the oil return chamber is arranged on the compressor back plate. According to the arrangement structure of turbocharger sealing rings, the sealing structure is optimized to better solve the sealing condition of a conventional supercharger, and the phenomena of oil leakage and gas leakage of the supercharger can be effectively prevented.
Description
Technical field
The invention belongs to turbo-charger technical field, especially relate to a kind of layout of Sealing Ring of Turbocharger.
Background technique
Turbosupercharger utilizes the energy of motor combustion gas to improve engine charge density, because pressurized machine has high power, low oil consumption, low emission, applies quite extensive at present on the engine.Lubrication is needed during pressurized machine work, pressurized gas are had when gas compressor and turbine end work, lubricant oil and gas is needed effectively to isolate, this effectively seals in turbine end and gas compressor end with regard to needs, sealing is not singly to reduce air or engine exhaust enters bearing support, is to stop the lubricant oil in bearing support to drain in volute and in compressor casing yet.What turbosupercharger sealing means was the most conventional is piston ring seal, owing to being non-contact seals, can there is a small amount of leakage of oil, gas leak phenomenon when pressurized machine runs, but excessive leakage of oil, the normal operation of leaking gas obstruction motor and pressurized machine.General employing twice piston type seal ring carries out sealing hydrocarbons, but under special operation condition condition, leakage of oil probably occurs in gas compressor end seal ring place, by the optimization to sealing mechanism, effectively can prevent the generation of pressurized machine gas leak of the oil leakage phenomenon.
Summary of the invention
In view of this, the present invention is intended to the layout proposing a kind of Sealing Ring of Turbocharger, in order to better solve the sealing condition of existing pressurized machine, is optimized sealing configuration, effectively can prevent the generation of pressurized machine gas leak of the oil leakage phenomenon.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of layout of Sealing Ring of Turbocharger, comprise gas compressor back of the body dish, shaft seal cover, seal ring, lubricating oil pod apertures, oil back chamber and central shaft, the excircle of described central shaft is provided with shaft seal cover, the excircle of described shaft seal cover is provided with gas compressor back of the body dish, described shaft seal is overlapped the surface of contact contacted with gas compressor back of the body dish and is provided with seal ring, described seal ring is provided with two, described gas compressor back of the body dish is provided with lubricating oil pod apertures, described lubricating oil pod apertures is placed between seal ring, lubricating oil pod apertures connects oil back chamber, and described oil back chamber is arranged on gas compressor back of the body dish.
Further, described lubricating oil pod apertures is the shaping or casting of machining.
Relative to prior art, the layout of a kind of Sealing Ring of Turbocharger of the present invention has following advantage:
The layout of turbosupercharging seal ring of the present invention adds lubricating oil flow guide structure in the middle of two seal rings, lubricant oil by first seal ring can be guided in oil back chamber, reduce after lubricant oil continues through second seal ring and occur leakage of oil situation, effectively can prevent the generation of pressurized machine gas leak of the oil leakage phenomenon.

The layout of a kind of Sealing Ring of Turbocharger mentioned in an embodiment of the present invention, comprise gas compressor back of the body dish 1, shaft seal cover 2, seal ring 3, lubricating oil pod apertures 4, oil back chamber 5 and central shaft 6, the excircle of described central shaft 6 is provided with shaft seal cover 2, the excircle of described shaft seal cover 2 is provided with gas compressor back of the body dish 1, the surface of contact that described shaft seal cover 2 contacts with gas compressor back of the body dish 1 is provided with seal ring 3, described seal ring 3 is provided with two, described gas compressor back of the body dish 1 is provided with lubricating oil pod apertures 4, described lubricating oil pod apertures 4 is placed between seal ring 3, lubricating oil pod apertures 4 connects oil back chamber 5, described oil back chamber 5 is arranged on gas compressor back of the body dish 1.
Described lubricating oil pod apertures 4 is the shaping or castings of machining.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, pressurized machine in the running, lubricant oil enters into the friction pair of lubrication such as needs such as thrust bearing 7 grade by oil inlet hole, lubricant oil enters oil back chamber 5 afterwards, the effect of seal ring 3 is stop lubricant oil to enter gas compressor ends that gas compressor back of the body dish 1 and shaft seal overlap 2 left sides, by being processed with lubricating oil pod apertures 4 in the middle of two seals ring 3, the lubricant oil entering first seal ring 3 can be allowed to flow back into oil back chamber 5 from lubricating oil pod apertures 4, thus minimizing lubricant oil flows through second seal ring 3 again, avoids occurring oil leakage phenomenon.
