As shown in Figure 1-2, a kind of novel two-way pump station cut-off device, the section of two-way water inflow passage 2 and Bidirectional water outlet runner 10 is rectangle, is formed by armored concrete cast; Umbrella sleeve 25 is metalwork, and facade is in being inverted umbrella shape, for hyperbolic cambered surface moulding; Sealing shroud 23 is abrasive rubber layer, and sealing shroud 23 realizes sealing after coordinating with stator cap 22; Cover plate 12 is circular ring metal plate, and the cavity on the downside of cover plate 12 external diameter and water pump top cover 14 is formed and is slidably matched, and cover plate 12 endoporus is formed with pump shaft 6 and is slidably matched; Arranging positioning spline 21 on pump shaft 6, cover plate 12 is moved up and down by positioning key 13 with umbrella sleeve 25 in positioning spline 21; It is provided with 2 road special-shaped seal rings 19 on the downside of cover plate 12 to coordinate with the formation sealing of water outlet Taper Pipe seal groove; All around, 4 positions are respectively equipped with lockhole 20, lockhole 20 and mechanical lock 18 position relationship one_to_one corresponding to cover plate 12; Water pump top cover 14 is circular metal structure, is bolted in the top board of Bidirectional water outlet runner 10, and gland seal device 16 is fixedly mounted on water pump top cover 14 upper end; Electromagnetic link mechanism 15 is 4 groups of electric magnet 24 that water pump top cover 14 is uniform with on the radius at cover plate 12 contact surface 2/3 place.
As it is shown in figure 1, a kind of novel two-way pump station cut-off device, according to water levels of upstream and downstream combination and service requirement, by opening different inlet gates and going out sluice gate, unit operation can be coordinated, it may be achieved irrigate by lifting water to a higher level with a water pump, etc., the row of carrying, from filling and from the function arranged.
Pumping plant is from row with from filling under two kinds of methods of operation, and water pump assembly is without devoting oneself to work.
(1) from row: when freshwater line is more than outer stream stage, it is desirable to during water drainage, then open inlet gate 1 and inlet gate 8.
(2) from filling: when outer stream stage is more than freshwater line, it is desirable to during irrigation, then open inlet gate 8 and inlet gate 1.
Pumping plant is in the row of carrying and irrigates by lifting water to a higher level with a water pump, etc. under two kinds of methods of operation, and water pump assembly need to be devoted oneself to work.
(3) row of carrying: when freshwater line is less than outer stream stage, or freshwater line is slightly larger than outer stream stage, but when requiring forced-ventilated, then open inlet gate 1 and go out sluice gate 17.
In the row's of carrying situation, after water pump assembly starts, water flows through inlet gate 1 and enters two-way water inflow passage 2, enters water pump vane room 3 from the surrounding of water guide cone 5 through water-inlet horn mouth 4, it is thus achieved that the water body of energy flows to water outlet Taper Pipe 11 from diffuser 7.It is pressed in the cover plate 12 on water outlet Taper Pipe 11 with the umbrella sleeve 25 being buckled on stator cap 22 under the impact of buoyancy and current, along positioning key 13 along pump shaft 6 upward sliding. Meanwhile, electromagnetic link mechanism 15 works, and electric magnet 24 produces suction, after cover plate 12 touches water pump top cover 14, electromagnetic link mechanism 15 Crush trigger blocking mechanism 18 works, and latch puts in lockhole 20, cover plate 12 is fixed, it is prevented that it is suspended in Bidirectional water outlet runner 10 and hinders current. After the latch of mechanical lock puts in lockhole 20, electric magnet 24 quits work, and loses magnetic force. Water body, is discharged through going out sluice gate 17 from water outlet Taper Pipe 11 through Bidirectional water outlet runner 10. After water pump assembly reaches rated speed, enter normal operating condition.
When water pump orderly closedown or accidental shutdown; electromagnetic link mechanism 15 dead electricity; mechanical lock 18 is threaded off automatically, and latch is retracted from lockhole 10, and cover plate 12 and umbrella sleeve 25 are under the effect of gravity and the stream that falls to sluice; along positioning key 13 along pump shaft 6 slide downward; cover plate 12 realizes sealing by fixing ring and water outlet Taper Pipe 11, and inner side is embedded with on the umbrella sleeve 25 stator cap 22 tightly of lamina wear-resisting rubber and realizes sealing, and unit is out of service; close out sluice gate 17, complete cutout process.
(4) irrigate by lifting water to a higher level with a water pump, etc.: when outer stream stage is less than freshwater line, it is desirable to during irrigation, then open inlet gate 8 and go out sluice gate 9.
In the situation of irrigating by lifting water to a higher level with a water pump, etc., after water pump assembly starts, water flows through inlet gate 8 and enters two-way water inflow passage 2, enters water pump vane room 3 from the surrounding of water guide cone 5 through water-inlet horn mouth 4, it is thus achieved that the water body of energy flows to water outlet Taper Pipe 11 from diffuser 7. It is pressed in the cover plate 12 on water outlet Taper Pipe 11 with the umbrella sleeve 25 being buckled on stator cap 22 under the impact of buoyancy and current, along positioning key 13 along pump shaft 6 upward sliding. Meanwhile, electromagnetic link mechanism 15 works, and electric magnet 24 produces suction, after cover plate 12 touches water pump top cover 14, electromagnetic link mechanism 15 Crush trigger blocking mechanism 18 works, and latch puts in lockhole 20, cover plate 12 is fixed, it is prevented that it is suspended in Bidirectional water outlet runner 10 and hinders current. After the latch of mechanical lock puts in lockhole 20, electric magnet 24 quits work, and loses magnetic force. Water body, is discharged through going out sluice gate 17 from water outlet Taper Pipe 11 through Bidirectional water outlet runner 10. After water pump assembly reaches rated speed, enter normal operating condition.
When water pump orderly closedown or accidental shutdown; electromagnetic link mechanism 15 dead electricity; mechanical lock 18 is threaded off automatically, and latch is retracted from lockhole 10, and cover plate 12 and umbrella sleeve 25 are under the effect of gravity and the stream that falls to sluice; along positioning key 13 along pump shaft 6 slide downward; cover plate 12 realizes sealing by fixing ring and water outlet Taper Pipe 11, and inner side is embedded with the umbrella sleeve 25 of lamina wear-resisting rubber and is enclosed within stator cap 22 tightly and realizes sealing, and unit is out of service; close out sluice gate 9, complete cutout process.
