Abstract
The utility model discloses an anti-leakage device of a coal gas pressure machine, and belongs to the technical field of fluid pumps. The anti-leakage device of the coal gas pressure machine aims to solve the leakage problem of the coal gas pressure machine. According to the technical scheme, the anti-leakage device of the coal gas pressure machine comprises a sealing cover and a gas vent pipe, the sealing cover is located between a machine shell of the gas pressure machine and a bearing case of a rotating shaft of the gas pressure machine, the sealing cover, the machine shell of the gas pressure machine and the outer shell of the bearing case form a sealing case body containing the end socket of the rotating shaft of the gas pressure machine together, one end of the gas vent pipe is connected with an exhaust vent of the sealing cover, and the other end of the gas vent pipe is located outside a machine room of the gas pressure machine. According to the anti-leakage device of the coal gas pressure machine, the sealing case body formed by the sealing cover, the machine shell of the gas pressure machine and the outer shell of the bearing case is used for collecting leaked gas, the collected gas is exhausted outside the machine room through the gas vent pipe, the fact that leaked gas gathered in the machine room is effectively prevented, and therefore personal safety of operation staff is guaranteed. In addition, the anti-leakage device of the coal gas pressure machine does not need high-pressure nitrogen, energy consumption is reduced effectively, and the operation cost of a pressure station is reduced.
Description
Technical field
The utility model relates to a kind of novel coal gas of converter pressuring machine sealing system, belongs to the fluid pump technical field.
Background technique
Coal gas is a kind of gas harmful to health, and the sealability direct relation of gas compressor spot check, operator's personal safety.At present, the simple contactless labyrinth seal structure of the general employing of gas compressor, principle is: many very little throttle clearance are arranged between the running shaft hole wall of running shaft and casing, and coal gas is after these throttle clearance, its pressure greatly reduces, and the coal gas Leckage is greatly reduced.In order further to improve sealing effect, some gas compressors pass into high pressure nitrogen (referring to Fig. 1) between the running shaft hole wall of running shaft and casing, while adopting this sealing system, no matter pressuring machine is in running state or stand-by state, and nitrogen all can not interrupt.The sealing system not only can consume more nitrogen, once and the working pressure of coal gas of converter pressuring machine higher than nitrogen pressure, or nitrogen stops confession for a certain reason, coal gas of converter will blow back in nitrogen pipeline, therefore has great potential safety hazard.
The model utility content
The purpose of this utility model is the drawback for prior art, and a kind of novel gas compressor leakage preventer is provided, and thoroughly eliminates accident potential and reduces the consumption of nitrogen.
Problem described in the utility model realizes with following technical proposals:
A kind of gas compressor leakage preventer, formation comprises seal closure and exhaust stack, described seal closure forms the seal case that contains gas compressor running shaft termination between the bearing housing of the casing of gas compressor and gas compressor running shaft and with together with the shell of the casing of gas compressor and bearing housing, one end of described exhaust stack is connected with the exhaust port of seal closure, and the other end is positioned at the machine room outside of gas compressor.
Above-mentioned gas compressor leakage preventer, between the casing of seal closure and gas compressor, be provided with sealing gasket between the shell of seal closure and bearing housing.
Above-mentioned gas compressor leakage preventer, also comprise the axle sleeve that is tightly placed in gas compressor running shaft end in formation, described axle sleeve is positioned at the rotary shaft hole of gas compressor casing, is provided with a plurality of annular tooth on its outer wall.
Above-mentioned gas compressor leakage preventer, the casing Spielpassung of described axle sleeve and gas compressor.
The utility model utilizes the coal gas of the casing of seal closure and gas compressor and the seal case collection leakage that the bearing housing shell forms, and by exhaust stack, the coal gas of collection is discharged to the machine room outside, the coal gas that has effectively prevented leakage is assembled in machine room, thereby has guaranteed operator's personal safety.In addition, the utility model does not need high pressure nitrogen, has effectively reduced energy consumption, has reduced the operating cost of pressurizing point.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of traditional gas compressor leakage protection device;
Fig. 2 is structural representation of the present utility model.
In figure, each label is: 1, running shaft; 2, casing; 3, nitrogen tube; 4, axle sleeve; 5, bearing housing; 6, plug; 7, exhaust stack; 8, seal closure; 9, sealing gasket.
Embodiment
The nitrogen tube that the utility model has been cancelled in traditional leakage preventer (blocks nitrogen connector in Fig. 2 with plug 6, can certainly not establish nitrogen connector), spindle nose position at the running shaft 1 of gas compressor arranges seal closure 8, with sealing gasket 9(felt mattress) sealed, and offer and diffuse hole on seal closure 8 tops, exhaust stack 7 is installed and is led to outside machine room, by exhaust stack 7, the coal gas leaked directly is discharged into outside machine room.
Because the pressuring machine axle head position pole of figure is irregular, especially spindle nose position, facility is more, as instrumentation pipeline, lubricating oil pipeline and other pipeline etc., for the structure that makes seal closure 8 does not affect other affiliated facility, the shape of seal closure 8 should be complementary with the shape of bearing housing 5.Seal closure 8 adopts the steel plate that thickness is ￡ 4 to carry out the simmering and bending making, with bolt, with pressuring machine casing 2, is connected, and forms the casing of a sealing, and the coal gas of converter of leakage is enclosed in casing.In order to guarantee that seal closure 8 is connected with casing 2 closely, must use good springiness, corrosion resistant sealing gasket between seal closure 8 and casing 2, bearing housing 5, therefore adopted the felt mattress of ￡ 2 to be sealed, guaranteed leakproofness.
