Description

A kind of cooling system of generating set
Technical field
The present invention relates to generator system, particularly relate to the cooling system of a kind of generating set.
Background technology
At present, the use of electromotor is very general, and high-rating generator is continuous firing often, and the electromotor of drive motor generating can continue to produce heat, if these heats are got rid of not in time, it will affect generating efficiency, result even in engine damage, cause heavy losses.Because hydrogen has desirable cooling performance, it is presently mainly and is cooled down by hydrogen cooler electromotor.
Usual enterprise can arrange two electromotors and generate electricity in turn, each electromotor is a supporting hydrogen cooler and hydrogen dryer individually, by the enclosed cooling water pump cooling water supply of self correspondence, due to method of operation reason, general only one electromotor of unlatching, it is contemplated that sake of economy, the enclosed cooling water pump of the electromotor of stoppage in transit is not turned on, the hydrogen cooler of the electromotor so stopped transport just does not have chilled(cooling) water supply (CWS), it is impossible to normally put into operation.Do not put into hydrogen dryer during shutdown, the humidity of generator hydrogen can be affected, reduce the insulating properties of electromotor.So wherein a generator outage time, in order to corresponding hydrogen dryer normally comes into operation, closed Water System is accomplished by reopening, and namely start big closed Water System wastes electricity, adds again the operational ton of operation.
Because above-mentioned defect, the design people, actively in addition research and innovation, a kind of under the premise being not turned on closed Water System to founding, hydrogen dryer also can the cooling system of generating set of bringing normally into operation so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide the cooling system of generating set that the cooling water of a kind of two electromotors can be standby each other.
The cooling system of the generating set of the present invention, described generating set includes two electromotors, each described electromotor all includes electromotor and connected motor, described cooling system includes two hydrogen coolers, hydrogen cooler described in two carries hydrogen respectively through the housing of electromotor described in two, and it is connected to hydrogen dryer respectively through pipeline, the port of export of hydrogen dryer described in two connects respectively through the arrival end of hydrogen cooler described in described pipeline and two, the cooling water oral siphon of hydrogen cooler described in two passes through the first cross current, the return pipe of hydrogen cooler described in two passes through the second cross current, described first water pipe and the second water pipe are equipped with two stop valves.
Further, also including two air accumulators that described cooling system provides hydrogen, the outlet of air accumulator described in two connects hydrogen cooler described in two respectively by described pipeline.
Further, the two described hydrogen dryers of connection and the described pipeline of described air accumulator further respectively have hydrogen filter.
Further, hydrogen desiccation agent all it is filled with in hydrogen dryer described in two.
By such scheme, the present invention is by being respectively turned on the oral siphon of two hydrogen coolers and return pipe, the cooling water that can make two hydrogen coolers is standby each other, avoid because of when wherein electromotor is stopped transport hydrogen dryer because of cooling water cannot the defect brought of regular supply, ensure the bringing normally into operation of hydrogen dryer, greatly strengthen hydrogen desiccation degree, improve the reliability of generator operation.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and can be practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Referring to Fig. 1, the cooling system of a kind of generating set described in a preferred embodiment of the present invention, generating set includes two electromotors, the electromotor 11 being respectively connected and motor 12, the electromotor 21 being connected and motor 22, cooling system includes two hydrogen coolers 13, 23, hydrogen cooler 13, 23 respectively through electromotor 11, the housing conveying hydrogen of 21, and respectively through pipeline 14, 24 connect hydrogen dryer 15, 25, hydrogen dryer 15, the port of export of 25 connects hydrogen filter 16 respectively, 26, hydrogen filter 16, 26, the port of export respectively through pipeline 14, 24 with hydrogen cooler 13, the arrival end of 23 connects.The cooling water oral siphon of hydrogen cooler 13,23 is connected by the first water pipe 30, and the return pipe of hydrogen cooler 13,23 is connected by the second water pipe 40, is equipped with two stop valves 50 on the first water pipe 30 and the second water pipe 40.So, when one of them electromotor such as stop transport with motor 12 by electromotor 11, the water pump that hydrogen cooler 13 is supplied water also can be stopped transport, the electromotor 21 that namely another electromotor is connected and motor 22 still work, accordingly, the water pump that hydrogen cooler 23 is supplied water still supplies water, due to hydrogen cooler 13, the cooling water oral siphon of 23 is connected by the first water pipe 30, open two stop valves 50 on the first water pipe 30, the cooling water of hydrogen cooler 23 enters in hydrogen cooler 13 by the first water pipe 30, thus the hydrogen in pipeline 14 can be cooled down by hydrogen cooler 13, hydrogen is made to be maintained at relatively low temperature, hydrogen dryer 15 also can continue hydrogen is dried, guarantee the aridity of hydrogen, to guarantee the insulating properties of electromotor.Again because the return pipe of hydrogen cooler 13,23 is connected by the second water pipe 40, opening two stop valves 50 on the second water pipe 40, the return pipe that the cooling water of hydrogen cooler 13 flows into hydrogen cooler 23 through its return pipe by the second water pipe 40 is discharged.
The present invention is respectively provided with two stop valves 50 on the first water pipe 30 and the second water pipe 40, and when being to prevent stop valve 50 inefficacy wherein, another stop valve 50 still can play the effect of cut-off.
When utilizing hydrogen that electromotor is cooled down, it is necessary to carrying out in pipeline 14,24 loop mending hydrogen, the present invention is all connected with air accumulator 16,26 on pipeline 14,24, and the outlet of air accumulator 16,26 connects hydrogen cooler 13,23 respectively by pipeline 14,24.
The present invention is respectively provided with hydrogen filter 17,27 on pipeline 14,24, is to ensure that the purity of hydrogen, to guarantee cooling effect.
Hydrogen is dried by the present invention by filling hydrogen desiccation agent in hydrogen dryer 15,25, and cost is low.
The present invention is by being respectively turned on the oral siphon of two hydrogen coolers and return pipe, the cooling water that can make two hydrogen coolers is standby each other, avoid because of when wherein electromotor is stopped transport hydrogen dryer because of cooling water cannot the defect brought of regular supply, ensure the bringing normally into operation of hydrogen dryer, greatly strengthen hydrogen desiccation degree, improve the reliability of generator operation.
The above is only the preferred embodiment of the present invention; it is not limited to the present invention; should be understood that; for those skilled in the art; under the premise without departing from the technology of the present invention principle; can also making some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
