Abstract
Disclosed is a sealing structure at a pressure end of a turbocharger, which comprises a gland (1), an impeller (2) and oil seal cover (3). The gland (1) is provided with a sealing circular groove in which a sealing ring (11) is arranged. A boss (21) is arranged on a hub of the impeller (2). The boss (21) is provided with the sealing circular groove in which a sealing ring (22) is arranged. The oil seal cover (3) is sleeved around the sealing ring (11) and the sealing ring (22). An oil slinger (31) is arranged on the position between the sealing ring (11) and the sealing ring (22) on the oil seal cover (3). The utility model has the advantages of compact structure, double independent sealing and good sealing effect.
Description
Technical field
The utility model relates to turbosupercharger pressure side structure, particularly a kind of turbosupercharger pressure side sealing configuration.
Background technique
At present, the sealing means of turbosupercharger pressure side generally is to adopt the piston type sealing, arranges seal ring in the pressure side of turbosupercharger, and the main effect of seal ring is that the gas of sealing in gas compressor and the turbine case leaks to the intermediate oil pocket.This seal ring have only just play a part under special circumstances the sealing machine oil, because the turbosupercharger wheel back of the body at its two ends (pressing the back of the body and the whirlpool back of the body) in normal operation locates that certain gas pressure is all arranged, machine oil is can not flow to the high pressure district from low pressure zone, but in real work, because sometimes the turbosupercharger air-intake negative-pressure is too big or dead time is long, is prone in the bearing support lubricant oil and breaks through the fault of seal ring to the pressure side seepage.As shown in Figure 3-4, in order to strengthen the sealability of pressure side, the turbosupercharger that has at present adopts adorns double seal ring (41,42) structure on the pressure side stuffing box gland, but because stuffing box gland position compactness, double seal ring (41,42) is difficult to arranged apart, cause double seal ring in fact only to play the effect of a seal ring, make sealing effect not good.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of turbosupercharger pressure side sealing configuration is provided, and its compact structure can form double independently sealing.
The technical solution of the utility model is: a kind of turbosupercharger pressure side sealing configuration, it comprises stuffing box gland, impeller and oil sealing cap, stuffing box gland is provided with closure gasket groove, in its closure gasket groove seal ring is installed, the wheel hub of impeller is provided with boss, boss is provided with closure gasket groove, in its closure gasket groove seal ring is installed.
The further technological scheme of the utility model is: described oil sealing cap is ridden and is enclosed within seal ring and seal ring periphery.
The utility model further technological scheme is: the position on the described oil sealing cap between seal ring and seal ring also is provided with gets rid of oilhole.
The also further technological scheme of the utility model is: the boss on the wheel hub of described impeller is provided with ring-shaped step corresponding to the position of getting rid of oilhole.
The utility model compared with prior art has following characteristics:
1, the seal ring on the wheel hub of seal ring on the utility model stuffing box gland and impeller is arranged apart, forms double independently sealing, its good sealing effect;
2, get rid of oilhole on the oil sealing cap, can avoid the pressure side leakage of oil to produce, reach better sealing effect.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
