Description

The cooling back installation that is used for dual feed wind generator
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 basically, and 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; The circulating water cooling device that opens wide is prone to pipeline blockage takes place, and is abandoned gradually, and 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, and 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 gets 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 scheme that the present invention taked is following:
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 through pipeline; Temperature transmitter is connected to pressure transmitter through pipeline, and pressure transmitter is connected to another pressure transmitter through pipeline, and pressure transmitter is connected to another temperature transmitter through pipeline; Temperature transmitter is connected to threeway temperature-sensing valve inlet through pipeline; The outlet of threeway temperature-sensing valve is connected to degassing tank through pipeline, and degassing tank is connected back to circulating water pump through pipeline, and the air bag expansion drum is through 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 gets 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 sketch map of the present invention.
Embodiment
As shown in Figure 1, circulating water pump 1 provides power, impels cooling water constantly circulation in circulation line 12; External interface 9 places sending and receiving thermal device, cooling water get into threeway temperature-sensing valve 13 through triple valve inlet 131 after external interface 9 places take away the heat of heater members; Threeway temperature-sensing valve 13 is made up of radiator valve and valve body two parts, predeterminable temperature on radiator valve, and 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; Export 133 places and be connected with external interface 10, external interface 10 places connect heat exchanger, export 132 and are connected to degassing tank 7 through circulation line; It can remove the free gas in the water; Electric heater 11 is set on the degassing tank 7, and when winter, temperature was low, it can add hot water; Let 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 through 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 through pipeline.
