Further explanation of the technical solution of the present invention with reference to the accompanying drawing
As shown in attached drawing 1,2, structure is that cooler inlet 28, cooler outlet 29 and labyrinth channel B partition 15 are respectively welded
On cooler gland 27, labyrinth channel A partition 14 is welded in cooler seat 13, and cooler cooling fin 12 is welded on cooler
13 outside surroundings of seat, cooler gland 27 are placed on pedestal 19, and gasket 26 is placed on cooler gland 27, cooler seat 13
It is pressed on gasket 26, cooler gland 27, gasket 26 and cooler seat 13 are fixed together by gland bolt 16, are formed
15 interlaced arrangement of labyrinth channel A partition 14 and labyrinth channel B partition, by cooler gland 27, labyrinth channel A partition 14, labyrinth
Channel B partition 15 and the combination of cooler seat 13 form labyrinth channel 25, and guide bearing 24 is mounted in cooler seat 13, and fan 10 is logical
Passing through fan fixing screws 8 are fixed on fan shaft 23, and fan shaft 23 is mounted in guide bearing 24, and fan guard 11 passes through 10 sets of fan
In 12 outside of cooler cooling fin, fan guard 11 and cooler cooling fin 12, cooler seat 13 form multiple air ducts 40, motor cabinet
9 are mounted on cooler gland 27, by bolt of lower base 17, pedestal nut 18 by motor cabinet 9, cooler gland 27 and pedestal 19
It being fixed together, motor 5 is mounted on motor cabinet 9, meanwhile, guarantee that motor reel 20 is inserted in fan shaft 23, passes through fan
Fan shaft 23 is fixed on motor reel 20 by axis fixing screws 21, and motor 5 and motor cabinet 9 are consolidated by bolt 6, nut 7
It is scheduled on together.Pumped (conveying) medium outlet 2 is communicated with hot water pump discharge 1, and pumped (conveying) medium outlet 2 passes through high-temperature conduit 3, valve 4
It is connected with cooler inlet 28, pump main shaft support bearing 31 is placed in bearing lubrication thin oil 32, and spiral coil cooling tube 34 is placed on
In bearing lubrication thin oil 32, cooler outlet 29 is communicated by cooling water pipe 30 with spiral coil cooling tube import 33, spiral coil cooling tube
Outlet 35 is communicated by hot-water line 36, pump inlet pipe refluxing opening 38 with pump inlet 39.In this way, foring complete heat-exchanger pump main shaft
The certainly cooling circulating system structure of spring bearing air blast cooling.
When work, the impeller 37 of rotation pumps high-temp liquid medium, and the liquid medium work done conveyed by 37 Duis of impeller is high
Geothermal liquid medium obtains energy from impeller 37, in this way, exporting the high-temp liquid medium tool for flowing to heat-exchanger pump outlet 1 from impeller 37
There are higher pressure energy and kinetic energy, under the action of pressure energy, high-temp liquid medium is flowed out from pumped (conveying) medium outlet 2, passes through high temperature
Water pipe 3, valve 4 flow into cooler inlet 28, into labyrinth channel 25, are adjusted by valve 4 according to cooling requirement and enter labyrinth
The flow in channel 25, labyrinth channel 25 be it is tortuous, high-temp liquid medium glide path in labyrinth channel 25 is longer, flowing compared with
Slowly, longer glide path and slower flowing are conducive to gradually transmit heat outward, in this way, efficiently by labyrinth channel 25
High-temp liquid medium heat is passed on the cooler cooling fin 12 being arranged in 13 outside surrounding of cooler seat, to reduce
The temperature of the high-temp liquid medium flowed in labyrinth channel 25, motor reel 20 rotate under the drive of motor 5, meanwhile, band
It is dynamic to cover 23 synchronous rotary of fan shaft on motor reel 20, and drive and cover 10 synchronous rotary of fan on fan shaft 23, wind
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.
