Embodiment
In Fig. 1, water intake (15) locate with in connect silk (13) and connect respectively to execute and open formula bottom valve (14) and ball valve (12), ball valve (12) is followed a plastic rigid pipe (11) again, plastic rigid pipe (11) is ined succession with elbow (10), and another is connected on plastic rigid pipe (9) in the threeway (8), the other end of threeway (8) and top in succession respectively a plastic rigid pipe (5) and a ball valve (7), ball valve (7) water filling hole (6) of ining succession, elbow (4) in succession respectively plastic rigid pipe (3) and (5), the ball valve (2) and plastic rigid pipe (3) is ined succession, ball valve (2) water outlet (1) of ining succession again.Energy-saving and environmental protection Ah nine formula self-priming water pump is assembled the back just can close ball valve (2) and (12), open ball valve (7), locate little water yield water filling with tubule toward water filling hole (6), until filling with.Can close ball valve (7) after filling with, water intake (15) is put into the water the inside, make water outlet (1) be lower than water intake more than (15) 1 meters, just can open spherical valve (2) subsequently, just can finish whole water absorption course.
This water-filling method is the fixing water flood of eminence opening, energy-saving and environmental protection Ah nine formula self-priming water pump must carry out with hard tube (plastic rigid pipe or iron pipe), can not use flexible pipe, pipe be inhaled flat distortion, cause water absorption little even do not inhale water with the words of the flexible pipe suction can be because of suction the time is excessive.Energy-conservation, the water intake (15) of environmental protection Ah nine formula self-priming water pump locate with in connect silk (13) and connect ball valve (12) respectively and execute and open formula bottom valve (14), this executes and opens formula bottom valve (14) and will put water the inside into, it is (energy-conservation necessarily can not to surface, the plastic rigid pipe bore of environmental protection Ah nine formula self-priming water pump is 20 centimetres and just requires and must open formula bottom valve (14) and put 1 meter dark water into executing, and is energy-conservation, the bore of the plastic rigid pipe of environmental protection Ah nine formula self-priming water pump just requires to open formula bottom valve (14) and put dried up the degree of depth that increases by 30 centimetres on original basis into executing 10 centimetres of every increases on the original basis).Locate to connect ball valve (12) with plastic rigid pipe (11) at the water intake (15) of energy-saving and environmental protection Ah nine formula self-priming water pump, plastic rigid pipe (9) and (11), (5) and (3) use elbow (10) and (4) to couple together respectively.Plastic rigid pipe (5) is connected with threeway (8) with (9), the ball valve (7) of on threeway (8), ining succession, and ball valve (7) is the gate valve of water filling hole (6).Open formula bottom valve (14) when putting water into because execute, can be subjected to buoyancy of water and can't make to execute opening formula bottom valve (14) closure, at this moment when water filling hole (6) water filling, because water injection rate is little, water can't make to execute to executing the buoyancy that opens formula bottom valve (14) less than the outer water of pipe and opens formula bottom valve (14) closure executing the pressure that opens formula bottom valve (14), in water filling, water also can from can't be closed execute to open the formula bottom valve and flow away, so can't be toward fills with water in the pipe.Therefore must open a ball valve of installation (12) above the formula bottom valve (14) executing, the flowing away of water when being used for preventing water filling is convenient to water filling, and this ball valve (12) must be contained in the bank, is convenient to personnel's operation.To add one 2 meters long interim water injecting pipe (6) above the ball valve (7), this water injecting pipe will be positioned over the highest point of whole piece pipe, after energy-saving and environmental protection Ah nine formula self-priming water pump fills with water, can close ball valve (7), interim water injecting pipe (6) is pulled down, interim water injecting pipe (6) exceeds 2 meters than plastic rigid pipe (5) and (9), just enough big toward water filling hole (6) pressure during water filling in pipe like this, the hydraulic pressure of generation is convenient to the interior air of pipe extruded and whole piece pipe fills with water.Try not after the fills with water to leave air in pipe, air can influence water absorption too much, even do not inhale water, the air of leaving in not allowing to manage greater than the drop between energy-saving and environmental protection Ah nine formula self-priming water pump water intake (15) and the water outlet (1) 15% (be meant that a whole piece pipe section remaining air accounts for 15% of this section water yield, rather than refer to the remaining altogether air of whole piece pipe add together 15%).Use plastic rigid pipe (3) to connect ball valve (2) at last and water outlet (1) gets final product.Energy-conservation, environmental protection Ah nine formula self-priming water pump installs the back just can open ball valve (7), close ball valve (2) and (12), toward the middle water filling of water filling hole (6), after in pipe, injecting a certain amount of water, energy-conservation, water in the environmental protection Ah nine formula self-priming water pump to execute open formula bottom valve (14) pressure greater than energy-conservation, the outer water of environmental protection Ah nine formula self-priming water pump is when executing the buoyancy that opens formula bottom valve (14), can open ball valve (12) (if energy-conservation, again ball valve (12) is opened after the environmental protection Ah nine formula self-priming water pump fills with water, can be many because of the water yield, pressure is big, at this moment a dozen shape valves (12) of kicking off will open formula bottom valve (14) and break through executing because of pressure is excessive.
After energy-saving and environmental protection Ah nine formula self-priming water pump fills with water, ball valve (7) is closed, water filling hole (6) is positioned over the peak of whole piece pipe, making the distance between peak and the water intake (15) is 2 meters, make water intake (15) be higher than water outlet (1) then, allow water intake (15) and water outlet (1) have 1 meter drop, drop is the bigger the better, and is unrestricted.Through evidence: one long 17 meters, bore is 34.5 millimeters energy-saving and environmental protection Ah nine a formula self-priming water pump, for the first time the water intake (15) of energy-saving and environmental protection Ah nine formula self-priming water pump is made as 2 meters high to the distance of peak, water intake (15) is 1 meter with the drop of water outlet (1), the water absorption that was produced in two minutes is 114 jin, a traditional unit of weight, and suction is 0.014mpa; For the second time the water intake (15) of energy-saving and environmental protection Ah nine formula self-priming water pump is made as 0 meter high (both not height) to the distance of peak, water intake (15) and water outlet (1) drop are 1 meter, and the water absorption that was produced in two minutes is 114 jin, a traditional unit of weight.(the height of the peak of these explanation energy-saving and environmental protection Ah nine formula self-priming water pump and the distance of water intake, water absorption is constant, but the height of the peak of energy-saving and environmental protection Ah nine formula self-priming water pump and the distance of water intake has change to suction, when their distance big more, suction is big more, distance is more little, and then suction is more little).Through evidence (using Fig. 1 scheme): long 17 meters of energy-saving and environmental protection Ah nine formula self-priming water pump, bore is 34.5 millimeters, has done 4 tests altogether.The water intake (15) of first three time test is 1 meter with the drop of water outlet (1), and the water intake (15) of the 4th test is 3 meters with the drop of water outlet (1).Testing for the first time water intake (15) is 2 meters to the distance of peak, and the suction of generation is 0.014mpa; Testing for the second time water intake (15) is 4 meters to the distance of peak, and the suction of generation is 0.017mpa; Testing water intake (15) for the third time is 5 meters to the distance of peak, and the suction of generation is 0.027mpa; The 4th test water intake (15) is 5 meters to the distance of peak, and the suction of generation is 0.04mpa, and more than the suction value of experiment gained is to be used in the vacuum instrumentation (vac) that vacuum packaging mechanical instrument company buys.
As shown in Figure 1, shown in the horizontal line (16) of energy-saving and environmental protection Ah nine formula self-priming water pump, when energy-saving and environmental protection Ah nine formula self-priming water pump does not have drop (17) (water intake and water outlet are in same horizontal line), such energy-saving and environmental protection Ah nine formula self-priming water pump can not normal operation.Be because water in energy-saving and environmental protection Ah nine formula self-priming water pump is when rising to peak with pipe position that the position that flows to water outlet from peak flushes from water intake, their climbing power and decline power are cancelled out each other, energy-saving and environmental protection Ah nine formula self-priming water pump does not have power without drop, so can not normal operation.Energy-saving and environmental protection Ah nine formula self-priming water pump is exactly to utilize the drop that exists between water intake and the water outlet to drive the flowing of water of whole piece pipe.When the water intake (15) of energy-saving and environmental protection Ah nine formula self-priming water pump is 2 meters to the distance of peak, drop is 1 meter, the pipeline length overall of energy-saving and environmental protection Ah nine formula self-priming water pump is 17 meters, and (water intake (15) is 8 meters to the peak pipe range, peak is 9 meters to water outlet (1) pipe range), energy-saving and environmental protection Ah nine formula self-priming water pump peak can not be oversize to the pipeline of water outlet (1), oversize words can influence water absorption (because energy-saving and environmental protection Ah nine formula self-priming water pump is to promote flowing of water by 1 meter drop between water intake and the water outlet.When pipeline is oversize, can increases resistance, thereby influence water flow).Equate with the distance of water intake (15) and work as energy-saving and environmental protection Ah nine formula self-priming water pump peak, when drop is different, then drop is big more, the water absorption of energy-saving and environmental protection Ah nine formula self-priming water pump is many more, and energy-saving and environmental protection Ah nine formula self-priming water pump is exactly that the active force that utilizes drop to produce drives the interior water of pipe.And not allowing the connecting part of each part that the phenomenon of gas leakage is arranged in energy-saving and environmental protection Ah nine formula self-priming water pump, if there is the situation of gas leakage to occur, is to influence water absorption.After getting everything ready at last, just can open ball valve (2), can finish whole water absorption course.
In Fig. 2, this water flooding regime is artificial water flood, when energy-saving and environmental protection Ah nine formula self-priming water pump gets length is 10 meters, locate respectively to install a ball valve (12) and (2) (when in pipe, carrying out the manual priming at water intake (15) and water outlet (1) respectively, require ball valve (12) below, ball valve (2) is up) be connected with plastic rigid pipe (18), then ball valve (12) that water intake (15) is located below with in connect silk (a 13) connection and execute and open formula bottom valve (14), load onto a water outlet (1) at the ball valve (2) at water outlet place.When water filling, close ball valve (12) earlier, (this water flooding regime must allow the water intake (15) of energy-saving and environmental protection Ah nine formula self-priming water pump low to open ball valve (2) again, water outlet (1) height, only in this way could be in the water ascending pipe, water filling must be injected from eminence, just will inject from water outlet (1), could be whole piece energy-saving and environmental protection Ah nine formula self-priming water pump fills with water).But it is on the contrary when energy-saving and environmental protection Ah nine formula self-priming water pump absorbs water, water intake (15) must be higher than water outlet more than (1) 1 meter, water intake (15) is better more than the low more height of water outlet (1), and the drop of water intake and water outlet is big more, and water flow also can increase.When the water that injects has 3 meters water levels, open ball valve (12) in energy-saving and environmental protection Ah nine formula self-priming water pump, just can make to execute and open formula bottom valve (14) closure, continue toward the water filling of energy-saving and environmental protection Ah nine formula self-priming water pump, till filling with.Can close ball valve (2) after the fills with water.
At last, the energy-saving and environmental protection Ah nine formula self-priming water pump of fills with water is moved to the place that need draw water, open formula bottom valve (14) and put water the inside into executing, water outlet (1) is placed on than water intake (15) and is lower than 1 meter place, open ball valve (2), can finish whole water absorption course.
In Fig. 3, this water flooding regime is diving suction engine water flood, two of plastic rigid pipe (26) connects suction engine (27) and elbow (25) respectively, with interior silk (24) connecting bend (25) and the ball valve (12) of connecing, use threeway (22) to connect ball valve (12) respectively again, elbow (20) and plastic rigid pipe (11), elbow (20) is ined succession one to execute and is opened formula bottom valve (14), plastic rigid pipe (3) is at water outlet (1) ball valve (2) of locating in succession, use a plastic rigid pipe (19) connecting bend (4) and (10) respectively then, elbow (4) plastic rigid pipe (3) of ining succession, elbow (10) plastic rigid pipe (11) of ining succession.All install the back diving suction engine (27) is put into the inside, water source.Can open ball valve (2) and (12), start diving suction engine (27), water is drawn in the pipe from diving suction engine (27), can close ball valve (2) and (12) after taking out full water in the pipe, stop the suction engine of diving under water, suction engine (27) dismounting of diving under water.The energy-saving and environmental protection Ah nine formula self-priming water pump of fills with water is moved to the place that need draw water, open formula bottom valve (14) and put water the inside into executing, water outlet (1) is placed on than water intake (15) and is lower than 1 meter place, opens ball valve (2), can finish whole water absorption course.
In Fig. 4, this water-filling method is a vacuum machine water flood, in connect silk (13) two in succession respectively to execute and open formula bottom valve (14) and plastic rigid pipe (11), elbow (10) in succession plastic rigid pipe (9) and (11), straight-through (29) in succession plastic rigid pipe (9) and transparent plastic steel wire tube (28), ball valve (12) in succession transparent plastic steel wire tube (28) and plastic rigid pipe (5), elbow (4) in succession plastic rigid pipe (3) and (5), ball valve (2) in succession plastic rigid pipe (3) and water outlet (1) are connected on water outlet (1) to vacuum machine (31) with vacuum suction pipe (30) at last and locate.After vacuum machine (31) connected, just can put the water the inside to water intake (15) into, open ball valve (2) and (12), start vacuum machine (31), when vacuum machine (31) is extracted into the pipe position of transparent plastic steel wire tube (28) to water, ball valve (12) is closed, continue the air in the remaining pipe is all extracted out, can close ball valve (2) after exhausting air, after the dismounting of vacuum machine, just can open ball valve (12), the plastic rigid pipe (3) and (5) that are under the vacuum condition can constantly be drawn into water in the pipe, till filling with the whole piece pipe, so just finished and be the process of whole piece pipe water filling.Open ball valve (2) at last again and can finish whole water absorption course.
