Establish the overflow mouth and through overflow pipe and subaerial reserve oil tank intercommunication through the highest oil level department at the main fuel tank, utilize the oil filter to pump the oil in the reserve oil tank to the main fuel tank in. The utility model has the advantages of simple structure, convenient and practical, utilize reserve oil tank both to solve and shut down or shut down for a long time the problem that prevents the full oil spill of main fuel tank when overhauing and go out in the accident, can regard as the additional oil sources of main fuel tank again, guaranteed the turbo generator set safe operation.
Description
Technical field
The utility model relates to steam turbine technology field, particularly relates to a kind of turbo-engine lube Self-Protection Subsystem.
Background technology
At present, most of thermal power plants in order to when ensureing that plant area has a power failure on a large scale turbine bearing pad normally for lubricating oil, prevent tile kilning, above turbine block, generally at 4m, install top petrol tank additional.When plant area large-scale blackout is shut down, in the case of all auxiliary oil pumps include that emergency bearing oil pump cannot be opened, cannot ensure lubrication pressure, lubricating oil needed for bearing shell during the backflow of lubricating oil can ensure that shutdown in top petrol tank.In order to meet the required fuel delivery in downtime, in top petrol tank, oil mass is probably at 2-3m.In the original lubricating oil system of steam turbine, as a example by 30MW unit, the volume of main fuel tank is generally 7m, it is ensured that the volume between the minimum oil level of unit safety operation and the highest oil level typically only has 2-3m.During Turbo-generator Set accidental shutdown or unit stop quotation on the exchange vehicle overhauling time, the lubricating oil (total measurement (volume) is more than 4m) in top petrol tank, main oil pump, each bearing shell and pipeline empties back into main fuel tank, and the full oil spill of fuel tank can be caused to go out.Some power plant in order to avoid when shutting down the full oil spill of main fuel tank go out; control main fuel tank oil level to run at minimum safe oil level, and once lubricating oil system somewhat seepage, main fuel tank oil level is less than minimum safe oil level; necessarily cannot ensure that unit continues safe operation, it is necessary to shutdown processes.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, easy to operate turbo-engine lube Self-Protection Subsystem, it is ensured that Turbo-generator Set safe operation.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of turbo-engine lube Self-Protection Subsystem; including main fuel tank, reserve fuel tank and oil filter; described reserve fuel tank and oil filter are arranged on the ground below main fuel tank; it is provided with overfall at the highest oil level on described main fuel tank; main fuel tank overfall is connected with reserve fuel tank by overflow pipe; oil filter oil-in is connected with the bottom oil-out of reserve fuel tank by oil pipe, and oil filter oil-out is connected with main fuel tank top oil-in by oil pipe.
Preferably, described oil filter oil-in is by oil-out and top oil-in thereof bottom oil pipe connection main fuel tank, and oil filter, also by oil pipe connection oil storage barrel and reserve fuel tank, all oil pipes is equipped with valve.
Preferably, described oil pipe is stainless steel tube and its a diameter of 50mm.
Preferably, described reserve fuel tank material is stainless steel.
Use and have the beneficial effects that produced by technique scheme: by arranging overfall at the highest oil level of main fuel tank, and overfall is connected by overflow pipe reserve fuel tank ground with lower section, utilize oil filter to be pumped to main fuel tank by the oil in reserve fuel tank.The utility model has simple in construction, convenient and practical advantage; utilize reserve fuel tank both to solve when accidental shutdown or long-time maintenance down and prevent the main fuel tank problem that completely oil spill goes out; again can be as the supplementary oil sources of main fuel tank, it is ensured that Turbo-generator Set safe operation, it is worthy of popularization.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment；
In figure: 1-main fuel tank, 2-reserve fuel tank, 3-oil filter, 4-overflow pipe, 5-oil pipe, 6-oil storage barrel, 7-valve.
Detailed description of the invention
With detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of turbo-engine lube Self-Protection Subsystem as shown in Figure 1; including main fuel tank 1, reserve fuel tank 2 and oil filter 3; described reserve fuel tank 2 and oil filter 3 are arranged on the ground below main fuel tank 1; it is provided with overfall at the highest oil level on described main fuel tank 1; A, B, C represent the highest oil level of main fuel tank 1, normal oil level, minimum safe oil level respectively, and overfall is i.e. opened at the highest oil level of main fuel tank 1；Main fuel tank 1 overfall is connected with reserve fuel tank 2 by overflow pipe 4, and oil filter 3 oil-in is connected with the bottom oil-out of reserve fuel tank 2 by oil pipe 5, and oil filter 3 oil-out is connected with main fuel tank 1 top oil-in by oil pipe 5.Meanwhile, oil filter 3 oil-in connects oil-out and top oil-in thereof bottom main fuel tank 1 by oil pipe 5, and oil filter 3 connects oil storage barrel 6 and reserve fuel tank 2 also by oil pipe 5, and all oil pipes 5 are equipped with valve 7, and the convenient oil circuit to each oil pipe 5 is controlled.
Wherein, described oil pipe 5 is stainless steel tube and its a diameter of 50mm, and described reserve fuel tank 2 material is stainless steel, and stainless steel can avoid permeability, and corrosion resistance is good, can extend its service life.
In actual applications, by arranging overfall at the highest oil level of main fuel tank 1, and overfall is connected by overflow pipe 4 reserve fuel tank ground with lower section 4, utilize oil filter 3 to be pumped to main fuel tank 1 by the oil in reserve fuel tank 2；Utilize oil filter 3 can pump bottom main fuel tank 1 and be delivered to the oil-in at main fuel tank 1 top, the oil in main fuel tank 1 is filtered again；Bottom reserve fuel tank 2, oil-out connects with main fuel tank 1 top oil-in through oil pipe 5, oil filter 3, is pumped by the oil in reserve fuel tank 2 and carries out oil sources to main fuel tank 1 and supplement；Meanwhile, oil filter 3 connects oil storage barrel 6 that reserve fuel tank 2 is carried out repairing is standby.
In sum; the utility model has simple in construction, convenient and practical advantage; utilize reserve fuel tank both to solve when accidental shutdown or long-time maintenance down and prevent the main fuel tank problem that completely oil spill goes out; again can be as the supplementary oil sources of main fuel tank; kill two birds with one stone; ensure that Turbo-generator Set safe operation, be worthy of popularization.
Obviously, embodiments described above is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
