10 rotation of fan generates biggish air quantity, is forced through and the air duct 40 of more pieces of cooler cooling fins 12 is housed in inner face, cold by more pieces
But the heat of device cooling fin 12 is taken away, and reduces the temperature on more pieces of cooler cooling fins 12, makees in the air blast cooling of fan 10
Under, the heat of high-temp liquid medium in labyrinth channel 25 is taken away by more pieces of cooler cooling fins 12 constantly, reduces fan
The temperature of high-temp liquid medium in palace channel 25, when reaching the cooler outlet 29 of labyrinth channel 25, high-temp liquid medium
Temperature has cooled to close to room temperature, is fully able to meet the cooling requirement of pump main shaft support bearing 31, the pump spring bearing of rotation
31 heats generated are absorbed by bearing lubrication thin oil 32, and 32 temperature of bearing lubrication thin oil is caused to increase, and spiral coil cooling tube 34 is placed
In bearing lubrication thin oil 32, the liquid medium flowed out from cooler outlet 29 introduces spiral coil cooling tube by cooling water pipe 30
Import 33 enters in spiral coil cooling tube 34, and cold medium and 32 thermal medium of bearing lubrication thin oil carry out heat in spiral coil cooling tube 34
Exchange causes medium temperature in spiral coil cooling tube 34 to increase, meanwhile, the temperature of bearing lubrication thin oil 32 is reduced, guarantees pump main shaft
31 working environment of spring bearing, the raised medium of this temperature enter pump inlet by hot-water line 36, pump inlet pipe refluxing opening 38
In 39, pumped again by impeller 37.So far, it completes to draw high-temp liquid Jie from the pumped (conveying) medium outlet 2 on hot water pump discharge 1
Matter carries out hot friendship by spiral coil cooling tube 34 and bearing lubrication thin oil 32 after labyrinth channel 25,12 air blast cooling of cooling fin
Change, finally return in pump inlet 39, by impeller 37 pump from cooling cycle, this process successively carries out, begin
Pump 31 working environment of main shaft support bearing is kept eventually, entire circulation is entirely closing, to the external world without any pollution, and energy conservation.
