Description
Technical field:
The utility model relates to a kind of sealing oil system, especially a kind of hydrogen double fluid ring sealing oil system.
Background technology
What present domestic 300MW, 600MW hydrogen cooled generator group adopted mostly is double fluid ring sealing oil system, adopt the unit ubiquity operation hydrogen purity of double fluid ring sealing oil system to descend fast, purification can only maintain the problem of moving under the lower state with the hydrogen amount is big with operation hydrogen purity parameter, having to, the frequent row's of employing hydrogen---the mode of mending hydrogen improves the purity of generator operation hydrogen, this has not only wasted great amount of manpower and material resources, and having a strong impact on the fail safe and the economy of unit, therefore double fluid ring sealing oil system also needs further perfect.
The sealing oil system principle:
Adopt the generating set of hydrogen cooling, in order to prevent that the gap of generator internal hydrogen by rotor and end caps to external leakage, is provided with special sealing device at the generator ' s cover place; Adopt double fluid ring sealing oil system at present mostly, this system is made up of empty side oil and two relatively independent oil supply systems of hydrogen side oil, its principle as shown in Figure 1, empty side and hydrogen side two road binders, by two cyclic ligand oil grooves on the difference supply shaft sealing bearing bush, form the two seals oil ring and stop escaping of the interior hydrogen of generator, oil flows out along the gap that rotor axial passes between sealing bearing bush internal diameter and rotating shaft then.If the fuel feeding oil pressure in these two oil circuits equates just at the sealing bearing bush place, oil just can channelling in the gap between two distributing grooves; Usually be higher than gas pressure in the machine as long as the sealing oil pressure remains, can prevent that just hydrogen from overflowing from generator.The oil that hydrogen side oil circuit is supplied with then will flow to the hydrogen side and flow into the froth breaking case along the gap between rotating shaft and the sealing bearing bush.The oil that the oil circuit of empty side is supplied with then will flow to the empty side oil sump tank of sky side along the gap between rotating shaft and the sealing bearing bush.
The function of sealing oil system and characteristics:
(a), provide the sealing oil sources of two independent loops, prevent that generator internal pressure gas from leaking along axle to sealing bearing bush.
(b), assurance sealing oil oil pressure is higher than gas pressure 0.084Mpa in the machine all the time, and guarantees that the hydrogen side equates that with empty side oil pressure Wei Te its differential pressure is limited in the allowed band in the sealing bearing bush.
(c) by cooler coolant seal oil, thereby take away the heat that produces because of the frictional dissipation between sealing bearing bush and the axle, guarantee that Wa Wen and oily temperature control are within claimed range.
(d) by oil filter, remove foreign material in the oil, guarantee the cleannes of sealing oil.
Empty side seal oil oil circuit:
Drive empty side seal oil pump by alternating current motor, obtain oil sources from empty side oil sump tank, it goes into the empty side of oil cooler, oil filter, sealing bearing bush to a part of oil pump, and another part oil then flows to oil pump oil-feed side through main differential valve.Adjusting by main differential valve remains at the oily oil pressure of the empty side seal at sealing bearing bush place on the level that exceeds gas pressure 0.084Mpa in the generator.Empty in addition side direct current stand-by pump circulates in an identical manner.
The hydrogen-side seal oil oil circuit:
Oil pump in the hydrogen-side seal oil oil circuit is obtained oil sources from hydrogen side oil sump tank, and it is the hydrogen side of part oil through oil cooler, oil filter, the past sealing bearing bush of balanced valve pump.On the oil pump side bypass duct is housed, hydrogen side oil pressure is carried out coarse adjustment by bypass valve.The oil pressure of hydrogen side oil circuit then carries out fine tuning by balanced valve, and makes it from the empty side oil pressure of motion tracking, to reach essentially identical level.Hydrogen side straightway pump is connected in parallel on the two ends of ac pump in addition, and hydrogen side straightway pump is circulated in an identical manner.
The harm that hydrogen purity is low:
(1) if hydrogen purity drops in the explosive range (4%---74%), may cause the hydrogen explosion in the generator under certain conditions; The defective cooling effectiveness that also can cause of hydrogen purity reduces, and causes the local overheating of machine inner member; The existence of pernicious gas also can cause the corrosion of ageing of insulation, iron core and metal parts thereof.
(2) if hydrogen purity descends, gas density will increase, and the draft loss that this has increased generator has reduced the operational efficiency (the generally every decline 1% of hydrogen purity, the draft loss of generator increases by 11% approximately) of generator; In order to improve the generator hydrogen purity, have to arrange hydrogen simultaneously---mend hydrogen, having increased purifies uses the hydrogen amount, has influenced the performance driving economy of generating set, has caused bigger economic loss to the power plant;
The analysis of causes that hydrogen purity descends:
Because balanced valve is the form of mechanical adjustment, be in operation, the gap is very little between balanced valve piston and the oil cylinder, have only 0.03mm, have impurity just may cause the resistance of motion of piston to increase slightly, in addition stuck, cause balanced valve degree of regulation variation, can not effectively keep the balance of sky, hydrogen-side seal oil pressure, cause sky, hydrogen-side seal oil to scurry oil mass and increase, and the generator hydrogen purity is descended;
The imbalance of empty side seal oil and hydrogen-side seal oil pressure, inevitably cause sky side oil and hydrogen side oil phase mutually between existence scurry oil, its exchange point is at sealing bearing bush and hydrogen side oil sump tank two places, exchange process is as follows: when empty side seal oil pressure is higher than hydrogen-side seal oil pressure, empty side seal oil is scurried oil at the sealing bearing bush place to the hydrogen side, gases such as air that contains in the empty side seal oil and moisture content can advance in people's generator froth breaking case, in the froth breaking case, escape into after the dilatation in the generator and reduce the purity of hydrogen, because empty side oil is scurried to hydrogen side oil, so hydrogen side oil sump tank oil level will raise and draining valve is opened, hydrogen side oil row is to empty side pump intake; When hydrogen-side seal oil pressure is higher than sky side seal oil pressure, hydrogen-side seal oil is scurried to empty side at the sealing bearing bush place, this will cause the oil level of hydrogen side oil sump tank to descend, hydrogen side oil sump tank Fill valve is opened repairing automatically, the empty side seal oil that contains air and moisture content advances people's hydrogen side oil sump tank, after hydrogen side oil pump boosted into people's sealing bearing bush, dilatation escaped in the generator and reduces the purity of hydrogen in generator froth breaking case again.This shows, no matter be that sky side seal oil pressure is higher than hydrogen-side seal oil pressure, still hydrogen-side seal oil pressure is higher than sky side seal oil pressure, all will cause scurrying mutually of sky side seal oil and hydrogen-side seal oil, and make the empty side seal oil that contains air and moisture content scurry people's hydrogen-side seal oil and reduce the purity of hydrogen in the generator machine.
