Description
Technical field
The present invention relates to a kind of cooling back installation that is used for dual feed wind generator.
Background technology
Can produce a large amount of heat in the running of dual feed wind generator, if untimely to its cooling, the stability of its operation will be interfered, and present cooling method is mainly water-cooling pattern.
Early stage water-cooling pattern is the direct current mode, and its utilance to water is lower; Present water-cooling pattern adopts recirculated water cooling mode substantially, in recirculated water cooling mode, the utilance of water is higher, it can be divided into the recirculated water cooling mode of unlimited recirculated water cooling mode and closed, pipeline blockage easily takes place in the circulating water cooling device that opens wide, abandoned gradually, the circulating water cooling device of closed then is difficult for taking place this kind phenomenon, yet, present most circulating water cooling device can't be in real time according to the water yield of the automatic adjusting of the water temperature of recirculated water with the heat exchanger heat exchange, therefore, its cooling effect is often not good.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can be in real time regulate the water yield that enters in the heat exchanger automatically, thereby can reach better cooling effect, be applied to the cooling back installation of dual feed wind generator according to water temperature.
The technical solution used in the present invention is as follows:
A kind of cooling back installation that is used for dual feed wind generator, the external interface that it comprises circulating water pump, temperature transmitter, pressure transmitter, threeway temperature-sensing valve, degassing tank, air bag expansion drum, circulation line, sending and receiving thermal device connects the external interface of heat exchanger; Circulating water pump is connected to temperature transmitter by pipeline, temperature transmitter is connected to pressure transmitter by pipeline, pressure transmitter is connected to another pressure transmitter by pipeline, pressure transmitter is connected to another temperature transmitter by pipeline, temperature transmitter is connected to threeway temperature-sensing valve inlet by pipeline, the outlet of threeway temperature-sensing valve is connected to degassing tank by pipeline, and degassing tank is connected back to circulating water pump by pipeline, and the air bag expansion drum is by pipeline and circulating water pump parallel connection.
Degassing tank is provided with electric heater.
The air bag expansion drum is provided with degassing tank.
The external interface of sending and receiving thermal device is arranged between pressure transmitter and another pressure transmitter.
The external interface that connects heat exchanger exports with the threeway temperature-sensing valve and is connected.
The invention has the beneficial effects as follows: this device can be regulated the water yield that enters in the heat exchanger according to water temperature in real time automatically, thereby can reach better cooling effect.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Embodiment
As shown in Figure 1, circulating water pump 1 provides power, impel cooling water constantly circulation in circulation line 12, external interface 9 places sending and receiving thermal device, cooling water is after external interface 9 places take away the heat of heater members, enter threeway temperature-sensing valve 13 by triple valve inlet 131, threeway temperature-sensing valve 13 is made up of radiator valve and valve body two parts, predeterminable temperature on radiator valve, threeway temperature-sensing valve 13 can be regulated outlet 133 and the water yield ratio that exports 132 of flowing out automatically according to the comparing result of water temperature and preset temperature, exporting 133 places is connected with external interface 10, external interface 10 places connect heat exchanger, export 132 and be connected to degassing tank 7 by circulation line, it can remove the free gas in the water, and electric heater 11 is set on the degassing tank 7, when winter, temperature was low, it can add hot water, allows water temperature reach preset value, 7 of the degassing tanks circulating water pump 1 that is linked back; The temperature transmitter 2,5 that is provided with in the circulation line and water temperature and hydraulic pressure in pressure transmitter 3, the 4 real-time signal pipings also show.
Air bag expansion drum 6 wherein presets the compressed air of certain volume by pipeline and circulating water pump 1 parallel connection, but causes the pressure oscillation that change in volume causes because water temperature changes in its balance circulation line 12, and air bag expansion drum 6 is connected to degassing tank 8 by pipeline.
