Abstract
A sealed axial-flow pump which can effectively prevent leakage is disclosed, wherein a mechanical sealing device is arranged on the contacting position of a pump shaft, a bent pipe and a water outlet pipe. As the mechanical sealing comprises a static sealing gasket, a static ring, a rotary ring, a rotary sealing ring, an outer sleeve of the rotary ring, a spring, and a spring seat and the like. When in frequent working, no clearance leakage caused by friction is produced, thereby the bearing can not be corroded, and the bearing can not be corroded or even jammed when the water pump is laid aside for some time. An oil sealing is arranged in front of the angular contact ball bearing in case of accident, and a slightly downward inclined ensuring hole is arranged on the bent pipe casing between the mechanical sealing and the oil sealing, thereby little water leaking into the sealing cavity, which is caused by accident reason can overflow from the ensuring hole.
Description
The utility model relates to a kind ofly can effectively prevent seepage, the mechanical device of protection axial-flow pump bearing.
At present, the bearing pump that is using is made up of impeller, diffuser, pump shaft, the pump housing, bend pipe, bearing, bearing support, motor etc. usually.Axial-flow pump is by the motor quick rotation, and the impeller rotation produces lift, makes water be drawn up.As the bearing of axial-flow pump vitals, can not contact with water.In order to prevent that drawing up the water that comes contacts with bearing, so oil sealing has been installed as seal arrangement in bearing the place ahead, and under oil sealing and the pump shaft quick rotation situation, because of the oil sealing that rubs can produce a gap with axle, in the bend pipe process of flowing through, contact with bearing by this gap infiltration, cause bearing rust, if it can be the bearing corrosion that water pump shelves that a period of time do not use, even blocks, make the lost of life of bearing.
The purpose of this utility model provides a kind of sealing axial-flow pump, and it can not only stop water to arrive in the bend pipe chamber to contact with bearing effectively, and accidental cause infiltration low amounts of water can be overflowed in the bend pipe chamber automatically.
The purpose of this utility model is to realize like this, infall at pump shaft and bend pipe and outlet pipe, load onto mechanical seal device, it generally is made up of sealing materials such as pad, stationary ring rubber seal, ceramic stationary ring, ceramic rotating ring, stainless steel rotating ring overcoat, rotating ring rubber seal, stainless steel spring, stainless steel spring seats.It can not produce the gap in rotating with pump shaft, an oil sealing is installed, further the seepage of anti-sealing in the angular contact ball bearing front.Simultaneously,, the water in the bend pipe chamber is discharged, on the bend pipe shell between mechanical seal and the oil sealing, open a slightly downward-sloping insurance hole, curved intraluminal low amounts of water can automatically be overflowed from the insurance hole in order to prevent under unexpected situation.
Because, adopted above-mentioned sealing prevent mean, under the axial-flow pump normal working, the gap that can produce because of seal arrangement not, and because of accidental cause at curved intraluminal water, the corrosion bearing makes the bearing rust extremely.
Below in conjunction with drawings and Examples the utility model is further specified:
Figure＜1〉be longitudinal section of the present utility model.
Figure＜2〉be the longitudinal section of mechanical seal.
Among the figure: 1. bend pipe 2. pump shafts 3. mechanical seal rings 4. insure holes 5. oil sealings, 6. angular contact ball bearings, 7. linings, 8. oiling screws, 9. radial ball bearings, 10. gland 16.11. flat keys, 12. shaft couplings, (pump shaft one end) 13. locking nuts 14. shaft couplings, (motor shaft one end) 15. motor shafts 17. lengthening end caps 18. pads 19. stationary ring rubber seals 20. ceramic stationary rings 21. bend pipe chambeies 22. outlet pipes, 23. ceramic rotating ring 24. stainless steel rotating ring overcoats 25. rotating ring rubber seals 26. stainless steel springs 27. stainless steel spring seats
This device is by a mechanical seal ring 3, and it comprises pad 18, stationary ring rubber seal 19, ceramic stationary ring 20, ceramic rotating ring 23, stainless steel rotating ring overcoat 24, rotating ring rubber seal 25, stainless steel spring 26, stainless steel spring seat 27.At angular contact ball bearing 6, by oil sealing 5, form simultaneously by an insurance hole 4.
When motor quick rotation impeller fast rotational produces lift; make water draw up; bend pipe 1, pump shaft 2, outlet pipe 22, infall load onto mechanical seal ring 3, for safety at angular contact ball bearing 6, oil sealing 5 is installed, stop go up the water that comes enter lining 7 in bend pipe chamber 21, the protection bend pipe, refuel screw 8, radial ball bearing 9, angular contact ball bearing 6, gland 10, flat key 11,16, shaft coupling (pump shaft one end) 12, locking nut 13, shaft coupling (motor one end) 14, motor shaft 15, not by aqueous corrosion, water flows out from outlet pipe 22.Simultaneously, in order to prevent accidental cause, on the bend pipe shell between mechanical seal ring and the oil sealing, open a slightly downward-sloping insurance hole 4, low amounts of water can be overflowed automatically.
Claims (1)
1 one kinds of sealing axial-flow pump, connect to form by impeller, diffuser, pump shaft, the pump housing, lifting pipe, bearing support bend pipe, motor etc., its special card is at pump shaft and bend pipe and outlet pipe infall, load onto mechanical seal device, at radial ball bearing and angular contact ball bearing front oil sealing sealing, and between depositing, mechanical seal and oil sealing open the insurance hole on the bend pipe.
