Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention: a kind of bushing type water fetching device of included backwash, as described in attached drawing 1-3, including
There is steel sleeve 11,11 head end of steel sleeve is densely covered with steel sleeve inlet opening 14, water pump 1 is equipped in steel sleeve 11, and water pump 1 is discharged
Mouth is connect through pumping line 2 with water-supply-pipe 10, and pumping line 2 is stretched out out of steel sleeve 11, further includes having backwash water pipe
9, backwash 9 head end of water pipe stretches to inside steel sleeve 11 head end to being provided at steel sleeve inlet opening 14, and its head end is through anti-
It rinses range pipe 13 to connect with multiple backwash spray heads 12, backwash 9 other end of water pipe is defeated with other set water fetching device
Water pipe 10 is connected to.It backwashes water pipe 9 and is equipped with shut-off valve 7.
Motion flow: the raw waters such as reservoir, lake or river water pass through the steel sleeve inlet opening 14 of the underwater end of steel sleeve 11
Into in steel sleeve 11, water pump 1 absorbs water from steel sleeve 11, defeated by entering after raw water pressurized delivered through pumping line 2
Water purification system or water use sector are supplied in water pipe 10.
After water pump 1 runs one period, the steel sleeve inlet opening 14 of 11 end of steel sleeve is by water float object or impurity
A degree of blocking is caused, opens shut-off valve 7 at this time, pressure water is defeated by pressure water through backwash water pipe 9 in pumping line 2
It is sent to backwash spray head 12, backwash spray head 12 flows out high-velocity flow and is rinsed to steel sleeve inlet opening 14, after the completion of flushing
Shut-off valve 7 is closed, restores to operate normally.Shut-off valve 7, which plays the role of backwashing, controls water flow on water pipe 9.
To steel sleeve inlet opening 14 backwash should other water pumps 1 run when carry out, avoid water pump 1 be discharged all into
Enter to backwash in water pipe 9, causes backwash 9 booster of water pipe or safety accident.
In installation process, water pump 1 is deep well pump or immersible pump, and motor and pump are integrated, motor hydraulic fitting.It takes
The water inlet of water pump 1 should below low water level 0.5m or more, avoid depth of the water submerging from being shallowly involved in very much air, guarantee pump sump safety
Reliably.The pumping line 2 of water pump 1 is water pump lifting pipe, generally uses steel pipe or ductile iron pipe, and clip or flange connect
It connects.Steel sleeve 11 is steel pipe or ductile iron pipe, consolidates water pump 1, while having protective effect to water pump 1, open-ended straight
Diameter 20mm's or so.Steel sleeve inlet opening 14 is filtered floating material in raw water and impurity, protects 1 operational safety of water pump.
Bulky grain suspended matter in water body intercept and avoids damaging water pump.The quantity of steel sleeve inlet opening 14 should be according to water pump
Flow carries out calculating determination.Steel sleeve 11 can be fixed vertically can also be with the angled fixation of horizontal plane on the slope, but inclines
Rake angle should not be too large, and need to carry out review confirmation according to pump sump condition, is fixed using pipe clamp or steel bracket etc..Steel bushing
11 caliber of pipe goes out greatly 100mm~200m than the shell sizes of water pump 1, meet installation of the water pump 1 in steel sleeve 11 and
Space is taken out in maintenance, while meeting the water suction requirement of water pump 1.Spray head 12 is backwashed to spray using the watering of diameter 25mm~32mm
Head is made of stainless steel, can be undertaken larger pressure and is not easy to plug, and spray head sprays high pressure water flow to steel sleeve inlet opening 14
Carry out flush clean.Backwash spray head 12 is connect using backwash range pipe 13 with backwash tube 9, backwashes range pipe 13
Diameter is identical as backwash spray head 12.
Water hammer-resistant check-valves 3, control are sequentially set on water-supply-pipe 10 and the water-supply-pipe 10 of backwash 9 junction front end of water pipe
Check valve 4, automatic exhaust steam valve 5 and pressure gauge 6.
Wherein, water hammer-resistant check-valves 3 is to prevent when 1 termination of pumping of water pump or recirculation water generates when accident instantaneous pressure is to taking
Water pump 1 or pumping line 2 and water-supply-pipe 10 damage, and the mode that check-valves adds water-hammer arrester can also be used.
Control gate valve 4 is the effect of truncation water flow or regulating water flow when water pump 1 overhauls, and manually or electrically side can be used
Formula is normally opened when water pump 1 is run.
Automatic exhaust steam valve 5 is used to empty the gas overflowed in pumping line 2, and it is disconnected to influence pipeline overcurrent to prevent air accumulation
Face.
Pressure gauge 6 is used to measure the actual pressure on water pump 1 and pumping line 2, can be pointer-type or digital, prison
Control the operating pressure of water pump 1.
Pressure reducing valve 8 and backwash flowmeter 17 are additionally provided on the backwash water pipe 9.
Pressure reducing valve 8 causes backwash spray head 12 to damage for stablizing backwash 9 internal water pressure of water pipe, in order to avoid water pressure is excessive
Or backwash effect is reduced, proportion expression or pressure reducing valve can be used, downstream pressure is according to hydraulic model test or according to practical work
Journey example determines.
Installation backwash flowmeter 17 on water pipe 9 is backwashed, hydraulic model test is carried out to backwash effect, is rinsed
The relatively good flow of effect adjusts 4 pairs of backwash flows of control gate valve by backwash flowmeter 17 and controls.
Another control gate valve 4 is additionally provided on water-supply-pipe 10 and the water-supply-pipe 10 of backwash 9 junction rear end of water pipe.Instead
4 open degree of control gate valve is adjusted when flushing, increases backwashing water flow, but backwashes flow to pass through accounting, in order to avoid pressure
Power is excessive.
Spherical rubber circle connector 18 is installed on the pumping line 2 in steel sleeve 11.It is placed in steel bushing 11,
For reducing the Vibration propagation of the operation of water pump 1.
Support construction 15 is equipped with inside steel sleeve 11, water pump 1 is fixed in support construction 15.The bottom in steel sleeve 11
The support construction 15 for welding water pump 1, plays certain carrying in vertical direction to water pump 1, in case water pump 1 is heavier,
The damage of pumping line 2 or interface leak are caused to the tensile load of pumping line 2 for a long time.
11 tail portion of steel sleeve is equipped with ring flange capping 19.It prevents sundries from entering in steel sleeve 11 and is deposited on the water suction of water pump 1
Area, or the steel sleeve inlet opening 14 of blocking steel bushing bottom of the tube, influence the water absorbing properties of water pump 1.
The steel sleeve 11 and backwash water pipe 9 are fixed on bank slope or dam body by pipe clamp 16.
Valve combination on pumping line 2 can be built in valve well, avoid valve it is exposed expose to the sun and rain make its use
Service life is reduced.
