Abstract
The utility model discloses a sealing oil system includes oil supply unit in proper order, enters the oil pipe way and goes out the oil pipe way, and oil supply unit connects into oil pipe way, enters the oil pipe way and is connected with a float oil tank with going out between the oil pipe way, advances oil pipe way, float oil tank and go out the oil pipe way to form circulation circuit, and circulation circuit has two sets ofly, just oil pipe 1 between two float oil tanks. The utility model discloses, made into to parallel the pair float oil tank that moves by float oil tank single among the prior art, modified float volume of fuel tank is 1.5 times bigger than original volume, has strengthened interference immunity, the ball -cock assembly of oil tank internal control liquid level also improves, and the current ball valve in ball -cock assembly design position has been kept away from the oil tank and has been imported and exported the pipeline, can fall to the disturbance that produces of flowing of medium minimum, the security that can improve sealing oil system has from many aspects avoided turbo generator hydrogen to reveal and the accident risk of generator oil feed.
Description
Technical field
This utility model is related to power domain and in particular to a kind of sealing oil system.
Background technology
Sealing oil system is the important aid system of hydrogen group, and conventional electromotor adopts the hydrogen-cooled but side of water
Formula, existing sealing oil system is single-flow seal oil, and the float oil tank system of single current ring has potential safety hazard, runs
Middle exist internal have interval abnormal sound, enter flowline and have vibration, fluctuate unstable, electromotor containing bubble, fuel level in tank in oil
Internal oil-feed and generator hydrogen leak equivalent risk.
Therefore need urgently to be improved, to avoid steam turbine generator that hydrogen leak and the accident of oil leakage in generator occur；
Utility model content
Technical problem to be solved in the utility model is existing sealing oil system unreasonable structure, hydrogen easily and lets out
Dew and the problem of oil leakage in generator.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that a kind of sealing oil system of offer,
Include fueller, in-line and outlet line successively, described fueller connects described in-line, described oil inlet pipe
It is connected with a float fuel tank, described in-line, float fuel tank and outlet line form and loop back between road and outlet line
Road, described closed circuit has two groups, and connects side by side between two described float fuel tanks.
In such scheme, in two described float fuel tanks, be respectively equipped with ball-cock assembly, described ball-cock assembly be located away from institute
State the import and export pipeline setting of float fuel tank.
In such scheme, described float fuel tank includes sky side fuel tank and the hydrogen side fuel tank being connected with electromotor respectively.
In such scheme, described sky side fuel tank is connected with air and extracts groove out.
In such scheme, described closed circuit is respectively equipped with the circulation bypass in parallel with each described float fuel tank, each institute
State and be respectively equipped with warning remote supervisory and control(ling) equipment in circulation bypass.
This utility model, is made into the duplex float fuel tank of paired running by single float fuel tank in prior art, improves
Bigger than original volume 1.5 times of float volume of fuel tank, enhance anti-interference；Fuel tank internal controls the ball-cock assembly of liquid level to be also carried out
Improve, ball-cock assembly design attitude more existing ball valve is away from fuel tank the import and export pipeline, the disturbance that can produce the flowing of medium
It is preferably minimized；The safety of sealing oil system can be improved from many aspects, it is to avoid steam turbine generator hydrogen leak and generating
The accident risk of machine oil-feed.
Brief description
Fig. 1 is the appearance schematic diagram of prior art；
Fig. 2 is appearance schematic diagram of the present utility model.
Specific embodiment
With reference to Figure of description, this utility model is described in detail.
As shown in Fig. 2 the sealing oil system of prior art is generally single-flow seal oil, only one of which float fuel tank
1, and the float oil tank system of single current ring has potential safety hazard, existing in operation internal have interval abnormal sound, enters flowline and have to shake
Containing bubble, fuel level in tank unstable, the generator oil-feed of fluctuation and generator hydrogen leak equivalent risk in dynamic, oily.
As shown in Fig. 2 this utility model provide a kind of sealing oil system, include successively fueller (in figure does not indicate,
Prior art can be adopted), in-line 2 and outlet line 3 (flow direction as shown by arrows in FIG.), fueller connects
Described in-line 2, is connected with a float fuel tank 1, in-line 2, float fuel tank 1 between in-line 2 and outlet line 3
Form closed circuit with outlet line 3, closed circuit has two groups, and connects side by side between two float fuel tanks 1.
It is further preferred that being respectively equipped with ball-cock assembly 5 in two float fuel tanks 1, ball-cock assembly 5 be located away from float fuel tank
1 the import and export pipeline, and employ the coarse domestic ball-cock assembly of the import ball-cock assembly alternative structure of advanced technology structure, can be by
The disturbance that the flowing of medium produces is preferably minimized.
It is further preferred that float fuel tank 1 is included sky side fuel tank 11 respectively and is connected with the generating set of sealing oil system
Hydrogen side fuel tank 12, empty side fuel tank 11 be connected with air extract out groove 4, generating set does not identify in figure, can adopt prior art.
It is further preferred that closed circuit is respectively equipped with the circulation bypass in parallel with each float fuel tank 1, in each circulation bypass
It is respectively equipped with warning remote supervisory and control(ling) equipment 6, improve system supervision property and anticipating risk ability further.
This utility model, is made into the duplex float fuel tank of paired running by single float fuel tank in prior art, improves
Bigger than original volume 1.5 times of float volume of fuel tank, enhance anti-interference；Fuel tank internal controls the ball-cock assembly of liquid level to be also carried out
Improve, ball-cock assembly design attitude more existing ball valve is away from fuel tank the import and export pipeline, the disturbance that can produce the flowing of medium
It is preferably minimized；The safety of sealing oil system can be improved from many aspects, it is to avoid steam turbine generator hydrogen leak and generating
The accident risk of machine oil-feed.
This utility model is not limited to above-mentioned preferred forms, and anyone should learn under enlightenment of the present utility model
The structure change made, every have same or like technical scheme with this utility model, each falls within guarantor of the present utility model
Within the scope of shield.
