Description
Technical field
The utility model relates to a kind of cooling unit, especially relates to a kind of horizontal water turbine bearing pedestal cooling device.
Background technique
Hydraulic system and lubrication system are the important component parts in some machinery.Hydraulic system operationally needs to maintain certain pressure, makes oil temperature raise after working long hours, if do not have good heat radiation, can cause that the seal element of system is aging, damage; The oil temperature of lubrication system raises many because of friction process generation heat, and same needs Oil-temperature control within the limits prescribed.The bearing support of horizontal hydrogenerator is provided with oil cooler, mostly is wind cooling oil cooler and water-cooled oil cooling machine according to heat exchange medium difference.Existing cooler, when ambient temperature is higher, is difficult to reach cooling requirement.
Model utility content
In order to overcome the defect of prior art, the utility model provides a kind of horizontal water turbine bearing pedestal cooling device, to improve the cooling problem of the horizontal water turbine when ambient temperature is higher.
In order to solve the problems of the technologies described above, the utility model provides a kind of horizontal water turbine bearing pedestal cooling device, and it comprises the cooler of bearing support; The cooling medium inlet pipeline be communicated with described cooler cooling medium inlet; With the cooling medium outlet conduit of described cooler cooling medium outlet; The oil inlet pipe be communicated with described cooler filler opening; The oil outlet tube be communicated with described cooler oil outlet; Be arranged on the oil pump on described oil inlet pipe or oil outlet tube, the auxiliary cooler be communicated with oil outlet tube with described oil inlet pipe; The cooling medium secondary inlet pipeline that two ends are communicated with auxiliary cooler cooling medium inlet with described cooling medium inlet pipeline respectively; With the cooling medium pilot outlet pipeline of described auxiliary cooler cooling medium outlet; Be arranged on the first valve on described cooling medium secondary inlet pipeline.
As further improvement opportunity scheme, the horizontal water turbine bearing pedestal cooling device that the utility model provides, also has the second valve be arranged on described oil outlet tube or oil inlet pipe.
As further improvement opportunity scheme, the horizontal water turbine bearing pedestal cooling device that the utility model provides, also has programmable controller; Be arranged on the temperature transducer on described oil outlet tube; Described first valve is modulating valve, and described temperature transducer is connected with programmable controller respectively with the first valve.
When not conflicting, above-mentioned improvement project can be implemented alone or in combination.
The technological scheme that the utility model provides, when ambient temperature is higher, the cooler of bearing support can not meet cooling when requiring.After opening the first valve, auxiliary cooler enters working state, cools to the fluid of cooling system, thus the cooling oil of bearing support is lowered the temperature, and ensures the normal operation of water turbine.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of embodiment's horizontal water turbine bearing pedestal cooling device.
Embodiment
Horizontal water turbine bearing pedestal cooling device as shown in Figure 1, comprise the cooler 4 of bearing support, cooling medium inlet pipeline 5 is communicated with the cooling medium inlet of cooler 4, the cooling medium outlet of cooling medium outlet conduit 3 and cooler 4, oil inlet pipe 2 is communicated with the filler opening of cooler 4, oil outlet tube 10 is communicated with the oil outlet of cooler 4, oil pump 8 is arranged on oil outlet tube 10, the filler opening of auxiliary cooler 11 is communicated with oil outlet tube 10, the oil outlet of auxiliary cooler 11 is communicated with oil inlet pipe 2, the two ends of cooling medium secondary inlet pipeline 7 are communicated with the cooling medium inlet of cooling medium inlet pipeline 5 with auxiliary cooler 11 respectively, the cooling medium outlet of cooling medium pilot outlet pipeline 1 and auxiliary cooler 11, first modulating valve 9 is arranged on cooling medium secondary inlet pipeline 7, second valve 6 is arranged on oil outlet tube 10, temperature transducer is arranged on oil outlet tube 10, horizontal water turbine bearing pedestal cooling device also has programmable controller, temperature transducer is connected with programmable controller respectively with the first modulating valve 9.When ambient temperature is higher, the cooler of bearing support can not meet cooling when requiring, the hydraulic fluid temperature of system rises, the information that temperature transducer detects is sent to programmable controller after conversion, when the hydraulic fluid temperature that temperature transducer detects reaches setting value, programmable controller transmit operation instruction, open the first modulating valve 9, auxiliary cooler enters working state, the fluid of cooling system is cooled, thus the cooling oil of bearing support is lowered the temperature, ensure the normal operation of water turbine; When the hydraulic fluid temperature of system drops to setting value, programmable controller transmit operation instruction, close the first modulating valve 9, auxiliary cooler is out of service; The information that programmable controller also can detect according to temperature transducer regulates the aperture of the first modulating valve 9, makes the oil liquid temperature of cooling system constant.
The utility model is not limited to above preferred implementation, in the spirit that also can limit in the utility model claim and specification, carries out conversion and the improvement of various ways, can solve same technical problem, and obtain the technique effect of expection, therefore not repeat.Those of ordinary skill in the art can from content disclosed in the utility model directly or all schemes associated, as long as within the spirit limited in claim, also belong to protection domain of the present utility model.
