Abstract
The utility model relates to a pumping type sealing device for an air compressor end of a pressurizer. The device comprises a shaft seal sleeve (1), an air compressor back disk (2) and a sealing ring (3), wherein the shaft seal sleeve (1) is sleeved on a turbine shaft; two ends of the shaft seal sleeve are respectively contacted with a thrust ring and an air compression blade wheel; the air compressor back disk (2) is sleeved on the shaft seal sleeve (1); and the sealing ring (3) is arranged between the excircle of the shaft seal sleeve (1) and the inner hole of the air compressor back disk (2). On the basis of the conventional sealing structure for the air compressor end of the pressurizer, the pumping type sealing device is additionally arranged; the pumping type sealing device has a simple structure and is practical; and the flow of lubrication oil can be effectively controlled, so that the negative pressure resisting sealing capacity of the air compressor end of the pressurizer is improved, the fault rate of oil leakage of the pressurizer is reduced, and the adaptability of the pressurizer under various working conditions of an engine is greatly improved.
Description
Technical field
The utility model relates to a kind of pressurized machine, is specifically related to a kind of pump suction type seal arrangement that is used for the supercharger air compressor end.
Background technique
Because pressurized machine has and improves engine power, reduces oil consumption, reduces characteristics such as effulent, on motor, uses quite extensive at present.In recent years along with the motor applying working condition is more and more wideer; Adaptive capacity to pressurized machine has proposed requirements at the higher level; Particularly in inland water transport, city bus operating mode, motor is longer service time at low speed, requires pressurized machine to have the anti-negative-pressure sealing ability of low speed preferably.Supercharger air compressor end design of Sealing Structure is increasing to the reliability effect that motor adapts to various operating modes.Existing supercharger air compressor end sealing device adopts double seal ring or the little Spielpassung of single seal ring to add the oil baffle structure more, evidence, and existing seal arrangement is when fixed operating mode or working conditions change are frequent; And under low speed operating mode shorter situation working time, can also meeting the demands, but occasions such as inland water transport now, city bus; Limit by various factors, it is bigger to load, and running speed is lower; Pressurized machine moves under the low speed operating mode for a long time, makes air compressor wheel back of the body place negative pressure bigger, causes gas compressor end seal ring pressure at both sides uneven; Make existing seal arrangement ineffective, cause the pressurized machine oil leakage fault.
Summary of the invention
The purpose of the utility model is to provide a kind of pump suction type seal arrangement that is used for the supercharger air compressor end; Simple in structure, practical; Can effectively control flow rate of lubricating oil; Improve the anti-negative-pressure sealing ability of supercharger air compressor end, reduce pressurized machine oil leakage fault rate, significantly promote the adaptive capacity of pressurized machine under the various operating modes of motor.
The technological scheme that the utility model adopts is: a kind of pump suction type seal arrangement that is used for the supercharger air compressor end; This device comprises a big envelope 1, gas compressor back of the body dish 2 and seal ring 3; Axle big envelope 1 is set on the turbine shaft; Two ends contact with compression impellor with Thrust ring respectively, and gas compressor back of the body dish 2 is set on the big envelope 1, and seal ring 3 is arranged between the endoporus of cylindrical and gas compressor back of the body dish 2 of a big envelope 1.
The utility model can be done following improvement, and a side cylindrical of axle big envelope 1 is provided with annular groove 14, and the opposite side cylindrical is provided with two row and gets rid of oilhole 11,13; Groove 12 is set on one side end face; Get rid of oilhole 11,13 and communicate with groove 12, gas compressor back of the body dish 2 is provided with boss ring 21, and boss ring 21 is inserted in the groove 12 of a big envelope 1; Seal ring 3 is installed in the annular groove 14 of a big envelope 1, relies on its elasticity tension closely to contact with the endoporus of gas compressor back of the body dish 2.
Described oilhole 11,13 quantity separately of getting rid of is greater than 2, and aperture separately is between Φ 0.5mm～Φ 5mm.
The cylindrical of described axle big envelope 1 and gas compressor back of the body dish 2 and interior interporal lacuna and end face and end clearance are all between 0.1mm～1mm.
The utility model compared with prior art has following beneficial effect: the utility model has increased the pump suction type seal arrangement on existing supercharger air compressor end sealing configuration basis; Simple in structure, practical; Can effectively control flow rate of lubricating oil; Improve the anti-negative-pressure sealing ability of supercharger air compressor end, reduce pressurized machine oil leakage fault rate, significantly promote the adaptive capacity of pressurized machine under the various operating modes of motor.

Embodiment
As shown in Figure 1, a kind of pump suction type seal arrangement that is used for the supercharger air compressor end, this device comprises a big envelope 1, gas compressor back of the body dish 2 and seal ring 3; Axle big envelope 1 is set on the turbine shaft, and two ends contact with compression impellor with Thrust ring respectively, and gas compressor back of the body dish 2 is set on the big envelope 1; One side cylindrical of axle big envelope 1 is provided with annular groove 14; The opposite side cylindrical is provided with two row and gets rid of on oilhole 11,13, one side end faces groove 12 is set, and gets rid of oilhole 11,13 and communicates with groove 12; Gas compressor back of the body dish 2 is provided with boss ring 21; Boss ring 21 is inserted in the groove 12 of a big envelope 1, and seal ring 3 is installed in the annular groove 14 of a big envelope 1, relies on its elasticity tension closely to contact with the endoporus of gas compressor back of the body dish 2.Getting rid of oilhole 11,13 quantity separately is 18, and aperture separately is Φ 2mm, and the cylindrical of axle big envelope 1 and gas compressor back of the body dish 2 and interior interporal lacuna and end face and end clearance are 0.3mm.
Working procedure is following; When lubricant oil gets into the gap between axle big envelope 1 and the gas compressor back of the body dish 2 under action of gravity; Axle big envelope 1 high speed rotating, the oilhole 11,13 that gets rid of on the axle big envelope 1 produces negative pressure in the high speed rotating process, the lubricant oil that gets into the gap is thrown away; Thereby improve the anti-negative-pressure sealing ability of supercharger air compressor end, reduce pressurized machine oil leakage fault rate.
