Abstract
The utility model discloses a vacuum purifier for sealing oil of an electric generator, belonging to the accessory of the shaft seal of the generator. The upper part of the main oil tank of the utility model is connected with a U-shaped pipe which is respectively communicated with an oil return pipe and an oil supply pipe. After the oil supply pipe is connected with an adjusting door in series, a vacuum oil tank is extended by the lower part of the oil supply pipe, and simultaneously the oil supply pipe is connected with the inlet of a direct current sealing oil pump. The lower part of the vacuum oil tank is connected with the inlet of an alternating current sealing oil pump by the oil pipe. The outlet of the alternating current sealing oil pump is connected with the outlet of the direct current sealing oil pump. After the outlet of the alternating current sealing oil pump is connected with an overflow valve in series, the vacuum oil tank is extended by the upper part of the alternating current sealing oil pump. The upper part of the vacuum oil tank is connected with a gas discharge pipe, and the vacuum oil tank is orderly connected with an electromagnetic valve, a vacuum pump and an oil fume separator in series. The utility model can purify the sealing oil, can enhance hydrogen purity and the cooling rate of the generator, can reduce auxiliary devices, and can facilitate the safe run of the generator.
Description
The utility model relates to a kind of generator sealing oil vacuum purification device, belongs to the shaft seal annex of generator.
At present, the dicyclic sealing bearing bush is generally adopted in the shaft seal of hydrogen, divide empty, hydrogen twice oil ring, oil supply system is two relatively independent systems, directly contact with the oil that prevents inferior quality with hydrogen, cause the hydrogen quality to descend, but because the sensitivity of balanced valve self, the precision of fuel injection pressure signal and the reasons such as gap of sealing bearing bush are difficult to avoid going here and there oily phenomenon, different the passing in the hydrogen side oil of empty side oil degree of inferior quality, contact with hydrogen, make that isolated gas (vapour) body mixes with hydrogen in the oil, cause the hydrogen quality to descend, in addition, turbine oil is in operation and can produces oil gas, enter in the generator, condense in coil surface, produce one deck greasy dirt, have a strong impact on the insulation level and the heat radiation of coil, the safety of generator is worked the mischief.
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of generator sealing oil vacuum purification device is provided, it can carry out purified treatment in advance with the oil that enters sealing bearing bush, except that contained gas, oil smoke and moisture content in deoiling, improve generator sealing bearing bush oil quality, prevent pollution, guarantee the safe operation of generator hydrogen.
The purpose of this utility model is achieved in that and is connected with U type pipe on its main fuel tank that U type pipe is communicated with oil return pipe and fuel feed pump respectively; The female pipe of fuel feed pump and lubricating oil is communicated with, and serial connection adjustment stretches into vaccum fuel tank from the bottom behind the door, its end installation nozzle, and simultaneously, fuel feed pump also is connected with the inlet of direct current sealing oil pump; The bottom of vaccum fuel tank is connected with interchange sealing oil pump inlet by oil pipe, exchanging the sealing oil pump outlet is connected with the outlet of direct current sealing oil pump, also by stretching into vaccum fuel tank from top behind the oil pipe serial connection overflow valve, this oil pipe is equipped with nozzle at vaccum fuel tank inner the branch, also is connected by the outlet of oil pipe with empty side seal oil pump simultaneously; The top of vaccum fuel tank connects gas discharge pipe, and it is serially connected with electromagnetically operated valve, vacuum pump and oil fume separator successively, and the oil fume separator below is connected with U type blowdown pipe.
Compared with prior art, advantage of the present utility model is because oil improves, reduced the pollution of oil greatly to hydrogen, make purity, the humidity of hydrogen remain on acceptable ranges, improved the generator cooling effectiveness, improved the service conditions of generator, help the safe operation of generator, simultaneously, significantly reduced row's hydrogen loss, can reduce blowdown flow rate 10950m every year
3, reduced auxiliary device platform number simultaneously, simplified system.
The explanation of accompanying drawing drawing:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.The utility model comprises main fuel tank (1), is connected with U type pipe (3) on the main fuel tank (1), and U type pipe (3) is communicated with oil return pipe (4) and fuel feed pump (2) respectively; Fuel feed pump (2) is communicated with lubricating oil mother's pipe (20), and stretches into vaccum fuel tank (17) from the bottom behind the serial connection adjustment door (18), and nozzle (19) is installed in its end, and simultaneously, fuel feed pump (2) also is connected with the inlet of direct current sealing oil pump (14); The bottom of vaccum fuel tank (17) is connected with the inlet that exchanges sealing oil pump (15) by oil pipe (16), exchanging sealing oil pump (15) outlet is connected with direct current sealing oil pump (14) outlet, also stretch into vaccum fuel tank (17) from top by oil pipe (5) serial connection overflow valve (13) back, this oil pipe (5) is equipped with nozzle (19) at vaccum fuel tank (17) the inner branch, also is connected with the outlet of empty side seal oil pump by oil pipe (8) simultaneously; The top of vaccum fuel tank (17) connects gas discharge pipe (6), and it is serially connected with electromagnetically operated valve (7), vacuum pump (12) and oil fume separator (11) successively, and oil fume separator (11) below is connected with U type blowdown pipe (10).
Oil in the female pipe of oil in the main fuel tank (1) and lubricating oil (20) enters vaccum fuel tank (17) through adjustment doors (18), through nozzle (19) atomizing, gas in the separating oil (vapour) body, clean oil is after exchange sealing oil pump (15) and boost, a part is delivered to the generator sealing bearing bush, another part is by oil pipe (5), overflow valve (13), gets back to vaccum fuel tank (17) atomize once more processings, the further oily cleanliness factor of raising.Gas (vapour) body in the vaccum fuel tank (17) is discharged by vacuum pump (12) through gas discharge pipe (6), enter oil fume separator (11), with the moisture of the oil that carries in gas (vapour) body and regelation from, oil enters sump oil case (9) from U type blowdown pipe (10), gas (vapour) body is then discharged by gas discharge pipe (6), adjusts door (18) and can control the interior oil mass of vaccum fuel tank (17), when oil level is too high, electromagnetically operated valve cuts out automatically, in case run oil; Cross when low when oil level, exchange sealing oil pump (15) and stop automatically.Cross low or exchange sealing oil pump (15) when breaking down when oil level, the direct current sealing oil pump starts automatically, directly gets oil by fuel feed pump (2) from female manage (20) of vaccum fuel tank (1), oil return pipe (4) or lubricating oil.
