Description
Technical field
The utility model relates to power plant's save the cost field, it is related to sealing oil system and drains the oil the Optimizing Reconstruction of door, specifically
An a kind of Optimizing Reconstruction of draining the oil under the special method of operation of 600MW Turbo-generator Set sealing oil system.
Background technique
General hydrogen cooler of generator leakage need to be by pressure pressure release in generator to zero, according to previous way, and one
After unit makes lock, cylinder of steam turbine temperature drop puts into compressed air quickly cooling device to 300 DEG C, and cylinder body is accelerated to be cooled to 150 DEG C,
Stoppage in transit rapid cooling, to cylinder temperature drop to 145 DEG C, stoppage in transit jiggering, Seal Oil, generator pressure release to zero, it usually needs 8 day time was reduced
Generated energy.
Summary of the invention
The purpose of the utility model is to provide a kind of Turbo-generator Set sealing oil system, it is engineered after system can contract
Bob motor pressure release maintenance downtime, reduces electric quantity loss, and system operation mode is flexible and varied.
To reach the purpose, the technical solution of the utility model is: a kind of Turbo-generator Set sealing oil system, including hydrogen
Cold generator, Seal Oil oil return enlarged slot, host grease-box, float fuel tank, air extract slot out, it is characterised in that: are sealing
Oily oil return enlarged slot is drained the oil pipeline to being equipped with first between host grease-box, and is drained the oil first and be equipped with enlarged slot extremely on pipeline
Host grease-box is drained the oil manually operated door, is equipped with second in Seal Oil oil return enlarged slot U-tube bottom and is drained the oil pipeline, and puts second
Oil-piping is equipped with U-tube to host grease-box and drains the oil manually operated door, and two-way, which is drained the oil, is commonly connected to host profit after pipeline converges
On oil tank.
When generator has 50KPa pressure above, its generator end sealing bearing bush oil return is extracted out by Seal Oil air
Slot is normally back to host grease-box;But the especially generator pressure when generator pressure is lower than 50KPa or less
The oil return of its sealing bearing bush is directly entered generator when for 0KPa, causes generator oil inlet dangerous, to guarantee this
Engine health not oil inlet under operating condition needs to open Seal Oil oil return enlarged slot and drains the oil to sky door of draining the oil into atmosphere, leads to ring
Border, which is polluted and existed, drains the oil not anxious and leads to generator oil inlet.
The utility model is by empty manually operated door of draining the oil being transformed to the master with negative pressure system Seal Oil oil return enlarged slot
The Seal Oil oil return enlarged slot U-tube road and bottom newly installed additional in this way after machine grease-box is drained the oil pipeline putting to main sump
On the one hand oil pipe line makes the smooth not oil inlet of generator Seal Oil oil return enlarged slot oil extraction, has on the other hand prevented environmental pollution, and
It is generator pressure in 0KPa, sealing oil system is not stopped transport, and quick defect elimination engine block defect provides guarantee.
The utility model is by empty manually operated door of draining the oil being transformed to the master with negative pressure system Seal Oil oil return enlarged slot
Pipeline is drained the oil to host grease-box in the Seal Oil oil return enlarged slot U-tube road and bottom newly installed additional in this way after machine grease-box
Pipeline of draining the oil, on the one hand make the smooth not oil inlet of generator Seal Oil oil return enlarged slot oil extraction, on the other hand prevented environment dirt
Dye, and in 0KPa, sealing oil system quick defect elimination engine block defect of not stopping transport provides guarantor for generator pressure
Card.
By an Optimizing Reconstruction of draining the oil, 600MW Turbo-generator Set sealing oil system uses the special method of operation: using not
Stoppage in transit jiggering, lubricating oil system, steam turbine, which is beaten, carries out generator gas displacement after lock, after the completion of gas displacement, reduces sealing bearing bush
To zero, Seal Oil returns main sump and passes through U-tube road and bottom that oil return enlarged slot newly installs additional for charge oil pressure generator pressure release simultaneously
Portion drains the oil pipeline to the pipeline of draining the oil of main sump, Seal Oil directly can be emitted into host grease-box.
After an Optimizing Reconstruction of draining the oil, stops transport and need to can handle 8 day time to Seal Oil, jiggering according to lock is made from steam turbine
Hydrogen cooler of generator calculates, and can be shortened the duration 6 days, reduces 86,400,000 degree of electric quantity loss, and pass through and facts have proved this
Kind of sealing oil system is drained the oil the feasibility of the special method of operation after an Optimizing Reconstruction.
Detailed description of the invention
Fig. 1 is the structure of modification schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing, the description of this part is only exemplary and explains
Property, it is not construed as the limitation to the utility model public technology content.
As shown in Figure 1, increase newly 2 valves: Seal Oil oil return enlarged slot to host grease-box drain the oil manually operated door 1, sealing
Oily oil return enlarged slot U-tube is drained the oil manually operated door 2.
Newly-increased first drains the oil pipeline 3: Seal Oil oil return enlarged slot to host grease-box is drained the oil pipeline (Φ 20mm, length
8m, stainless steel 304 SS).
Newly-increased second drains the oil pipeline 4: Seal Oil oil return enlarged slot U-tube is drained the oil pipeline (Φ 20mm, length 55m, stainless steel
304SS)。
The course of work is as follows:
1, in Fig. 1, after being replaced into air in generator, when pressure is down to 100KPa in machine, Seal Oil is slowly opened
Oil return enlarged slot grease alarm sewage door, makes pressure in machine be slowly lowered to zero.
2, when pressure is down to 80KPa in generator, zero meter begins through adjustment Seal Oil differential valve bypass manually operated door
Oily hydrogen differential pressure is controlled 30KPa to 35KPa (monitoring differential pressure gauge on the spot);Until pressure is down to 0KPa in generator.
3, during pressure is down to 0KPa by 100KPa in generator, float fuel level in tank should be looked over one's shoulder;When its oil level
Raising or oil extraction are opened float fuel tank bypass manually operated door control float fuel level in tank in time, are answered when the full oil of float fuel tank when unsmooth
By the bypass door standard-sized sheet and close the oily manually operated door of float fuel tank disengaging;Look over one's shoulder whether three grease alarms have oil simultaneously.
4, when pressure is down to 0KPa in generator, should open with lower valve: float fuel tank bypasses manually operated door, and enlarged slot is extremely
Float fuel tank U-tube is drained the oil manually operated door and what is newly installed additional drain the oil manually operated door 2 to host grease-box, enlarged slot grease alarm row
Dirty manually operated door, generator #1, #2 grease alarm blowdown manually operated door.
5, it periodically turns on enlarged slot to drain the oil manually operated door and what is newly installed additional drain the oil manually operated door 1 to host grease-box, be put
Oil operation, to prevent oil leakage in generator;If enlarged slot grease alarm blowdown manually operated door simultaneously, the alarm of generator #1, #2 grease
It is any when thering is oil to be discharged at device blowdown manually operated door, should continuously open enlarged slot drain the oil manually operated door and newly install additional to host lubricating oil
Case is drained the oil manually operated door 1, until oil-free discharge at the above sewage door.
6, during Seal Oil is drained the oil, host grease-box oil level is looked over one's shoulder, oil level is prevented to fluctuate.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within protection scope with novel claims.
