Description
Technical field
The present invention relates to a kind of bearing block, and in particular to a kind of dual-purpose axle of the special forced air-cooling water cooling of cfentrifugal blower
Bearing.
Background technology
Cfentrifugal blower is because its exiting exhaust gas end gas compression and friction reason temperature are up to more than 100 DEG C, to protect
Card air blower safe operation must carry out pressure cooling to the bearing installed in the port of export.Apply and exported in centrifugal blower now
End is water-cooling bearing block, and no matter how ambient air temperature changes, and can only all be circulated by cooling water in annular water tank to strengthen
Bearing radiates, and is so that unnecessary waste is caused to water resource first；Secondly there is sub-cooled in the case where temperature is relatively low
Phenomenon, cause bearing running temperature too low, be unfavorable for bearing lubrication and stable operation.
The content of the invention
The purpose of the present invention is exactly for overcome the deficiencies in the prior art, and provides air blower special forced air-cooling water cooling two
Use bearing block.
The technical solution adopted by the present invention is to achieve these goals：
The special dual-purpose bearing block of forced air-cooling water cooling of air blower, including bearing block, bearing cap, rubber seal ring, closure, water inlet
Air inlet crossover tee, water intaking valve, intake valve, water outlet outlet crossover tee, outlet valve, air outlet valve, it is characterised in that：Described axle
Have closure between bearing and bearing cap, there is two rubber seal rings between closure and bearing block, closure and bearing block it
Between have annular cooling duct, the symmetry direction of closure is respectively provided with into water air inlet crossover tee and water outlet outlet crossover tee, entered
Water intaking valve and intake valve are housed on water air inlet crossover tee, outlet valve and air outlet valve are housed on water outlet outlet crossover tee；Need
When being cooled down using air, intake valve, air outlet valve are opened, water intaking valve, outlet valve are closed, and intake valve is free air-suction state, is gone out
Air valve pipeline communication carries out forced ventilation to blower inlet using blower inlet negative pressure；When needing to use water cooling, it will enter
Air valve, air outlet valve are closed, and water intaking valve, outlet valve are opened, and are cooled down using forced water circulation.
Compared with prior art the beneficial effects of the invention are as follows：Bearing block has air cooling and water cooling both of which, is saving
Ensure the safe operation of bearing while largely using water.
Brief description of the drawings
Fig. 1 is the structural representation of existing cfentrifugal blower bearing block；
Fig. 2 is the structural representation of the embodiment of the present invention；
Icon explanation：1. bearing block；2. bearing cap；3. rubber seal ring；4. water inlet；5. delivery port；6. closure；7.
Water inlet air inlet crossover tee；8. water intaking valve；9. intake valve；10. water outlet outlet crossover tee；11. outlet valve；12. air outlet valve；
13. annular cooling duct.
The invention will be further described below in conjunction with the accompanying drawings.
Embodiment
Fig. 1 is the structural representation of existing cfentrifugal blower bearing block；Existing cfentrifugal blower bearing block includes axle
Bearing 1, bearing cap 2, rubber seal ring 3, water inlet 4, delivery port 5, water enter from water inlet 4, flow out, reach from delivery port 5
Cooling effect, during operation, have in the case that temperature is relatively low sub-cooled phenomenon occur, be unfavorable for bearing lubrication and
Stable operation.
Embodiment
Fig. 2 is the structural representation of the embodiment of the present invention；The special dual-purpose bearing block of forced air-cooling water cooling of air blower of the present invention, including
Bearing block 1, bearing cap 2, rubber seal ring 3, closure 6, water inlet air inlet crossover tee 7, water intaking valve 8, intake valve 9, water outlet goes out
Gas shift threeway 10, outlet valve 11, air outlet valve 12, it is characterised in that：There is closure between described bearing block 1 and bearing cap 2
6, there are two rubber seal rings 3 between closure 6 and bearing block 1, there is annular cooling duct 13 between closure 6 and bearing block 1, it is close
The symmetry direction of capping 6 is respectively provided with into water air inlet crossover tee 7 and water outlet outlet crossover tee 10, air inlet crossover tee of intaking
Water intaking valve 8 and intake valve 9 are housed on 7, outlet valve 11 and air outlet valve 12 are housed on water outlet outlet crossover tee 10.Autumn and winter temperature
When relatively low, intake valve 9, air outlet valve 12 are opened, water intaking valve 8, outlet valve 11 are closed, and intake valve 9 is free air-suction state, outlet
The pipeline communication to blower inlet of valve 12, forced ventilation is carried out using blower inlet negative pressure, saves and largely uses water, ensures axle
The safe operation held.The water cooling when summer environment temperature is higher, intake valve 9, air outlet valve 12 are closed, water intaking valve 8, outlet valve
11 open, and are cooled down using forced water circulation.
