Description
Technical field
The invention belongs to technical field of generators, are specifically related to a kind of auxiliary equipment of hydrogenerator, especially send out
Motor oil groove anti-oil mist overflowing and condensation deposition structure.
Background technique
Bearing of hydraulic generator generally uses self-lubricating plain bearing, and bearing liner invades profit in lubricating oil.When unit operates
When, one side lubricating oil is stirred repeatedly in oil groove, is hit, and a large amount of bubbles are generated, and mist of oil is just formed after these bubble eruptions；
On the other hand, temperature is higher at the tiling oil film part of bearing liner, and lubricating oil vaporizes 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 mainframe
The linear velocity of group is higher, sputters oil everywhere, the mist of oil of generation is more, and severity dramatically increases.The linear velocity of Large-scale machine set
Greatly, the mixing speed in oil groove increases accordingly fastly, 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 caused.
To solve the problem of turbine-generator units spilled oil phenomenon and mist of oil phenomenon and pollution environment, causing insulation fault,
In hydrogenerator shaft and sealing structure, there are in the case where gap, used external tonifying Qi, multilayer labyrinth in the prior art
The auxiliary equipments such as sealing, contact formation testing gear, oil mist absorbing device, are blocked to mist of oil or are carried out separating treatment, are achieved certain
Effect, but the effect is unobvious sometimes, part mist of oil between shaft and the gap of sealing structure along axial spilling, into sky
Environment is polluted in gas.In the prior art, such as Patent No. ZL201620899008.0, applying date 2016-08-18, entitled
In the utility model patent file of " a kind of power generation sump oil mist control device ", discloses and stretch out oil groove sealing in alternator shaft
It on the lateral surface of lid, is provided at least one circle and keeps off oily hairbrush, keep off the technical side that oily hairbrush is arranged along alternator shaft outer circumference surface
Case, because hairbrush oil absorbing effect preferably, be conveniently replaceable, be cheap the advantages that, when mist of oil from gap overflow when, by hairbrush quilt
The mist of oil of hairbrush absorption, hairbrush absorption condenses on hairbrush, has effectively blocked the gap, prevents mist of oil from overflowing from the gap；Both
Protection environment improves safety again, can prevent mist of oil from overflowing the insulation fault that may cause.
But this kind of structure, because the mist of oil amount overflowed outward is more, the mist of oil of hairbrush absorption is accordingly more, but also is to have
The mist of oil of fraction overflows outward from gap, pollutes the environment, and such as handles not in time, and mist of oil is easy to cause insulation thing
Therefore.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of power generation sumps for hydrogenerator
Anti-oil mist overflowing and condensation deposition structure, block the mist of oil in oil groove, the oil-containing gases aspirated in oil groove on one side are passed through
Oil mist remover is handled, and is passed through into oil groove on one side to keep air pressure balance in oil groove in gas, can prevent mist of oil from
Pollution environment is overflowed in oil groove, and the oil-containing gases for entering oil mist remover can be carried out in advance condensation deposition with reduce into
The oil mass for entering oil mist remover mitigates the processing load of oil mist remover.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：A kind of power generation sump oil mist prevention
It overflows and condensation deposition structure, including alternator shaft, oil groove sealing cover, oil groove sealing cover is by the space of alternator shaft lower part
Sealing forms the oil groove of storage lubricating oil；It is characterized in that, intersecting the outside at position in oil groove sealing cover and alternator shaft
On face, it is provided at least one circle sealant and air inlet port and gas pump orifice is set on oil groove sealing cover, taken out in gas
It is equipped with suction channel on suction inlet, connects oil mist remover through suction channel.
Further feature is, on suction channel, is provided with fuel tank, the sectional area of fuel tank is greater than the section of suction channel
Product.
Oil pump is provided in fuel tank, oil pump connects oil return pipe, and manually or automatically fuel primer pump, passes through oil return pipe for oil liquid
Extract fuel tank out.
One end U-tube is set, and U-tube is located at the bottom end of suction channel, fuel tank is arranged in suction tube on suction channel
On the U-tube in road.
The other end of oil return pipe connects oil groove, and oil liquid is flowed back into oil groove and is recycled.
Disc is set on the alternator shaft being located in oil groove, and disc is rotated in company with alternator shaft.
In oil groove, it is provided with oil-stabilizing plate, oil-stabilizing plate is not rotated with alternator shaft, the height with oil groove inner fluid liquid level
It matches.
The beneficial effects of the present invention are：
1, sealant is set between hydrogenerator shaft and sealing cover side, has effectively blocked hydrogenerator shaft
The gap between sealing cover prevents mist of oil from overflowing from the gap.
2, the oil-containing gases on one side in suction oil groove are passed through oil mist remover and are handled, and lead on one side 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 passes through gap between hydrogenerator shaft and sealing cover and enters
Oil groove can prevent mist of oil from overflowing out of oil groove by the gap.
3, the fuel tank being arranged on the suction channel of oil mist remover has condensation deposition, the oily in pipeline
Body generates 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.
