Description
Technical field
The invention belongs to technical field of generators, a kind of auxiliary equipment of hydrogenerator is specifically related to, is especially sent out
Motor oil groove anti-oil mist overflowing and condensation deposition structure.
Background technology
Bearing of hydraulic generator typically uses self-lubricating plain bearing, and bearing liner invades profit in lubricating oil.When unit operating
When, one side lubricating oil is stirred, hit repeatedly in oil groove, produces and mist of oil is just formed after a large amount of bubbles, these bubble eruptions；
On the other hand, temperature is higher at the tiling oil film part of bearing liner, and lubricating oil is vaporized at relatively high temperatures, also forms mist of oil.Cause
This, for hydrogenerator, the generation of mist of oil is inevitable, and increasing with generating unit speed, especially large scale computer
The linear velocity of group is higher, oil is sputtered everywhere, the mist of oil of generation is more, and the order of severity is dramatically increased.The linear velocity of Large-scale machine set
Greatly, in oil groove accordingly increase is fast for mixing speed, bigger to stirring and effect of impact power, spilled oil phenomenon easily occurs and mist of oil is existing
As not only having polluted environment but also insulation fault may be triggered.
To solve turbine-generator units spilled oil phenomenon and mist of oil phenomenon, and the problem of pollution environment, initiation insulation fault,
In the case where hydrogenerator rotating shaft and sealing structure have gap, in the prior art using excessively outside tonifying Qi, multilayer labyrinth
The auxiliary equipments such as sealing, contact formation testing gear, oil mist absorbing device, are blocked or are carried out separating treatment to mist of oil, are achieved certain
Effect, but DeGrain sometimes, part mist of oil overflows vertically between rotating shaft and the gap of sealing structure, into sky
Environment is polluted in gas.In the prior art, if Patent No. ZL201620899008.0, the applying date are 2016-08-18, entitled
In the utility model patent file of " a kind of generating sump oil mist control device ", disclose and stretch out oil groove sealing in alternator shaft
On the lateral surface of lid, at least one oily hairbrush of circle gear, the technical side that the oily hairbrush of gear is set along alternator shaft outer circumference surface are provided with
Case, because hairbrush oil absorbing effect preferably, be conveniently replaceable, it is cheap the advantages of, when mist of oil overflows from gap, by hairbrush quilt
Hairbrush is adsorbed, and the mist of oil of hairbrush absorption is condensed on hairbrush, has effectively blocked the gap, prevents mist of oil from being overflowed from the gap；Both
Environmental protection improves security again, can prevent mist of oil from overflowing the insulation fault that may trigger.
But, this kind of structure, because the mist of oil amount outwards overflowed is more, the mist of oil of hairbrush absorption is accordingly more, but also is to have
The mist of oil of fraction is outwards overflowed from gap, and environment is polluted, and is such as handled not in time, mist of oil easily triggers insulation thing
Therefore.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of generating sump for hydrogenerator
Anti-oil mist overflowing and condensation deposition structure, are blocked to the mist of oil in oil groove, while the oil-containing gases in suction oil groove are passed through
Oil mist remover is handled, while be passed through into oil groove to keep air pressure balance in oil groove in gas, can prevent mist of oil from
Overflow pollution environment in oil groove, and the oil-containing gases for entering oil mist remover can in advance be carried out condensation deposition with reduce into
Enter the oil mass of oil mist remover, mitigate the processing load of oil mist remover.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：A kind of generating sump oil mist prevention
Overflow and condensation deposition structure, including alternator shaft, oil groove closure, oil groove closure is by the space of alternator shaft bottom
Sealing, forms the oil groove of storage lubricating oil；Characterized in that, the outside at the position that intersected in oil groove closure and alternator shaft
On face, at least one circle sealant is provided with, on oil groove closure, air inlet port and gas pump orifice is set, taken out in gas
Suction channel is equipped with suction inlet, oil mist remover is connected through suction channel.
Further feature is, on suction channel, is provided with fuel tank, and the sectional area of fuel tank is more than the section of suction channel
Product.
Oil pump is provided with fuel tank, oil pump connects oil return pipe, and manually or automatically fuel primer pump, oil return pipe is passed through by fluid
Extract fuel tank out.
One end U-tube is set on suction channel, and U-tube is located at the bottom of suction channel, and fuel tank is arranged on suction tube
On the U-tube in road.
The other end connection oil groove of oil return pipe, is back to oil groove by fluid and recycles.
Disc is set on the alternator shaft in oil groove, and disc is rotated in company with alternator shaft.
In oil groove, oil-stabilizing plate is provided with, oil-stabilizing plate is not rotated with alternator shaft, the height with oil groove inner fluid liquid level
It is engaged.
The beneficial effects of the present invention are：
The 1st, sealant is set between hydrogenerator rotating shaft and closure side, effectively blocked hydrogenerator rotating shaft with it is close
Gap between capping, prevents mist of oil from being overflowed from the gap.
2nd, while the oil-containing gases in suction oil groove are passed through oil mist remover and handled, while leading to from trend oil groove
Enter in gas to keep air pressure in oil groove in a basic balance, and the gas flow being automatically drawn into oil groove is less than oil mist remover
The gas flow of suction, forms negative pressure in oil groove, and extraneous gas is entered by gap between hydrogenerator rotating shaft and closure
Oil groove, can prevent mist of oil from being overflowed by the gap out of oil groove.
3rd, the fuel tank set on the suction channel of oil mist remover has the oily in condensation deposition, pipeline
Body produces condensation deposition in the fuel tank, and oil is automatically separated with gas, is deposited in fuel tank, reduces and enters oil mist remover
Oil mass, mitigates the processing load of oil mist remover.
