Embodiment
It is the mining multistage drainage system automatic water diversion device of one kind that the utility model embodiment provides referring to Fig. 1, Fig. 2,
As shown in Figure 1 and Figure 2, which includes automatic water-leading component, and the automatic water-leading component includes closed case 1, suction hose 2, row
Water pipe 3, air bleeding valve 4 and the observation mudhole 5 with sealing mechanism；The suction hose 2 connects with 1 top of closed case
Logical, the drainpipe 3 is connected with 1 lower part of closed case, and the air bleeding valve 4 and the observation mudhole 5 are respectively positioned on institute
State 1 top of closed case；1 volume of closed case is 2~3 times of 2 volume of suction hose；
Water pump component, the water pump component include water pump body 6, the water inlet end of the water pump body 6 and the drainpipe 3
It is connected.
Further, the suction hose 2 is provided with the first filter screen 7, the suction hose away from described 1 one end of closed case
2 are provided with the second filter screen 8 with 1 junction of closed case, and the observation mudhole 5 is located at second filter screen 8
Top.1 lower part of closed case is provided with to carry the stent 9 of the closed case.The closed case use thickness 6~
The Q235 steel plates of 8mm are made.The closed case is internally provided with transverse and longitudinal reinforcing rib (not shown) arranged in a crossed manner.
The closed case 1 has circular or square exterior contour structure.The water pump body 6 includes water outlet, the water outlet
It is connected with diversion valve 10.Water injection valve 11 and water filling cup 12, the closed case bottom are additionally provided at the top of the closed case
Cleaning pipe 13 is additionally provided with, closure silk cap is provided in the cleaning pipe.The device is pacified in use, by water injection valve to the pump housing
And water tank with water, it is just to need to note in the case that only water is drained in the case without water filling under usual normal operation
Water when water filling cup only will be used to draw water for the first time, is used pump housing water filling.Cleaning pipe can be sealed with silk plug, for clean because it is long when
Between using siltation the impurity such as mud.
The automatic water diversion device that the application provides removes the bottom valve of water pump, is changed to sealing radiator.It is first when starting mode of pump
The water in water tank is first sucked, since the water inside water tank is drained in a short time, water tank is made to form parital vacuum, so that inhaling
Water in well is pressed into water tank under the action of atmospheric pressure, by suction hose, so as to ensure that the proper drainage of water pump.From
Dynamic diversion component is made of babinet, water inlet pipe, outlet pipe, filter screen, air bleeding valve, sewage draining exit etc.；Babinet is made generally using thickness 6
The Q235 steel plates of~8mm make, and the thickness of material can be determined according to the actual lift of water pump using babinet, if Yang Cheng higher
Thicker material can be used in place, avoid impact force that high pressure water flow after repeatedly having a power failure suddenly because of water pump recoils and babinet because
Atmospheric pressure causes welding box body position cracked the pressure of babinet when there is vacuum, makes babinet that can not work normally.Case
The shape of body can be fabricated to the shapes such as circular and square, can be determined according to the space of place to use and the size of water pump.According to
2~3 times of suction hose volume is commonly reached using the volume of experience babinet can meet actual operation requirements, to ensure babinet
Seal, it is desirable that each welding point is secured, reliable, air tight；Box house can add lacing wire simultaneously, to ensure the intensity of babinet.
For suction hose bottom filters is avoided to fail, a filter screen and observation panel and sewage draining exit should be installed additional in babinet, in order to clear up
And blowdown, but to ensure that it reaches seal request.
The performance parameter checking computations for the mining multistage drainage system automatic water diversion device that the application provides：
The bottom valve set in water filter on centrifugal water pump suction piping not only increases the resistance of ducting, increases energy
Amount consumption, reduces pump efficiency, and decreases the water suction of water pump, Lin Kuang groups strain cypress colliery -400m central pump houses
The type water pump of three MD280-43 × 6 of configuration carries out vacuum using self-waterer, since its vacuum state and without bottom valve are arranged
Water mode is identical, thus the calculation of devising a stratagem really of its parameter is identical with no bottom valve mode.Calculating process is as follows：

The operating point is acquired on Q-H coordinates:Flow Qm=279m3/h, lift Hm=236m, efficiency etam=0.77.It is preferable in water pump
Working condition.In formula：Hsy- water pump geodetic altitude；The metered flow of Q-selected water pump.
Application effect of the mining multistage drainage system automatic water diversion device that the application provides on centrifugal water pump mainly has
The following：
(1) due in mine water contain minerals and a large amount of coal slime sandstone, for a long time using be easy to cause bottom valve corrosion and
Damage, particularly large pump, bottom valve volume is big and heavy, and conditions down-hole is poor in addition, bad environments；Maintenance and replacement bottom valve labor
Fatigue resistance is big, is also easy to influence the proper drainage of water pump, which is just not present analogue.
(2) running bottom valve of water pump is often present with because quality problems cause to damage, suck sundries and because having a power failure suddenly
Or it since operating personnel's error causes bottom valve bad seals, fills discontented diversion and can not start, which is then not present this feelings
Condition.
(3) since the device does not have the resistance that bottom valve accordingly reduces pipeline, the energy expenditure of water pump itself is reduced, greatly
The big work efficiency for improving water pump；Simultaneously for having bottom valve draining pump, under conditions of identical suction head, drop
The low vacuum degree at the Pump Suction mouth of a river, reduces the generation of cavitation phenomenons in water pump operation, reduces maintenance cost, with regard to strain cypress coal
For ore deposit -400m central pump house main drain pumps, when using bottom valve every year must gug overhaul, when maintenance finds water pump chopped-off head
Impeller and guide vane impeller and guide vane damage caused by cavitation phenomenons occurs are more serious, and without bottom valve tank drains has been used to fill certainly
After putting, substantially gug overhaul in 2 years is once, annual only to carry out light maintenance and regular maintenance in underground, greatly reduces repair
Cost and
Overhaul labor intensity.
(4) low manufacture cost only needs the Master Cost of 2~3 bottom valves to ensure that and uses for a long time.
(5) power savings are good, left than electric energy 11~15% is saved with bottom valve per hour with model water pump according to preresearch estimates
It is right.By actual measurement, there is bottom valve pump discharge 280m3Water, power consumption 278.6kw.h；And without bottom valve pump often arranges 280m3Water, power consumption
257.7kw.h.Often arrange 280m3Water, can economize on electricity 20.9kw.h.Strain cypress colliery daily displacement about 4000m3It calculates, by improving ratio
There are bottom valve economize on electricity 298.57kw.h, year economize on electricity 107485kw.h..
(6) property promoted the use of is strong, and using effect is ideal.
In short, the mining multistage drainage system automatic water diversion device reduces operational sequence in mine drainage practical application
And drainage efficiency raising has played positive effect, improving anti-disaster ability for mine provides guarantee, is coal mine underground water drainage device
The technology being worthy to be popularized.
