Abstract
The utility model relates to the technical field of sealing oil systems, in particular to a generator sealing oil system, which comprises a main bearing of a generator, a sealing pad, a sealing pad support, an air side annular gap and a hydrogen side annular gap. An air side sealing oil inlet is arranged on the sealing pad, and a sealing pad floating oil-air lateral port and a hydrogen side sealing oil inlet are further connected to two sides of the sealing pad. The generator sealing oil system solves the problems in the prior art, is simple in structure, stable in work and long in service life, and can reliably run.
Description
Technical field
The utility model relates to a kind of sealing oil system, relates in particular to a kind of generator sealing oil system.
Background technology
At present, the sealing oil device effect of using on market is all undesirable, prescribes a time limit when hydrogen side mailbox is lower than down usually, sends the signal of telecommunication by fluid level control device and makes the electromagnetically operated valve action, connect the repairing pipeline, hydrogen side fuel tank is carried out repairing, when liquid level is mended specified altitude, the electromagnetically operated valve outage, repairing stops, such structure descends sky side oil pressure when empty side oil supply system is carried out repairing to hydrogen side mailbox rapidly, causes the instability of sky side seal oil pressure, causes sky side seal watt fuel feeding deficiency when serious.
The utility model content
The technical problems to be solved in the utility model is: structure of the prior art descends sky side oil pressure when empty side oil supply system is carried out repairing to hydrogen side mailbox rapidly, cause the instability of sky side seal oil pressure, cause sky side seal watt fuel feeding deficiency when serious, a kind of generator sealing oil system is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises the base bearing of generator, also comprise sealing bearing bush, sealing bearing bush bearing, empty side ring shape gap and hydrogen side ring shape gap, described sealing bearing bush is provided with sky side seal oil oil-in, and described sealing bearing bush both sides also connect unsteady oily empty side mouth of sealing bearing bush and hydrogen-side seal oil oil-in.
According to another embodiment of the present utility model, comprise that further described sealing bearing bush bearing has labyrinth collar.
The beneficial effects of the utility model are: the utility model is revised at the problem that prior art exists, and provides a kind of simple in structure, the generator sealing oil system of working stability, this generator sealing oil system energy reliability service, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, base bearing, 2, sealing bearing bush, 3, the sealing bearing bush oily empty side mouth that floats, 4, empty side seal oil oil-in, 5, the hydrogen-side seal oil oil-in, 6, the sealing bearing bush bearing, 7, labyrinth collar, 8, empty side ring shape gap, 9, hydrogen side ring shape gap.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Fig. 1 is a structural representation of the present utility model, the base bearing 1 that comprises generator, also comprise sealing bearing bush 2, sealing bearing bush bearing 6, empty side ring shape gap 8 and hydrogen side ring shape gap 9, described sealing bearing bush 2 is provided with sky side seal oil oil-in 4, and described sealing bearing bush 2 both sides also connect unsteady oily empty side mouth 3 of sealing bearing bush and hydrogen-side seal oil oil-in 5.Described sealing bearing bush bearing 6 has labyrinth collar 7.
The utility model is revised at the problem that prior art exists, and provides a kind of simple in structure, the generator sealing oil system of working stability, this generator sealing oil system energy reliability service, long service life.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
