Door a closes；
If hydraulic pressure value Pw2bLess than threshold k2b, then controller 12 indicate the second line pump 3 stop, and indicate electric draining lock
Door b closes.
The water that this step is directed in boring is exhausted dry situation.Hydraulic pressure value Pw1Less than threshold k1I.e. suction pump 1
Input cannot extract water in boring, controller 12 instruction suction pump 1 stops, and prevents suction pump 1 from dallying.Hydraulic pressure value
Pw2aLess than threshold k2aI.e. the input of the first line pump 2 cannot extract the water in the first water storage device 4, and controller 12 indicates
First line pump 2 stops, and prevents the first line pump 2 from dallying.Hydraulic pressure value Pw2bLess than threshold k2bThe i.e. input of the second line pump 3

The water drawdown that this step is directed in boring is maintained at the situation of a certain height for a long time.Hydraulic pressure value Pw1With air pressure
Value PA1Difference can reflect that drawdown is constant, now controller 12 instruction suction pump 1 run setting time T1After stop,
Then the first line pump 2, the second line pump 3 stop in succession, terminate drill-hole pumping test.
Further, the described control method based on the above-mentioned pumping equipment for drill-hole pumping test, also includes following
Step：
If hydraulic pressure value Pw2aLess than threshold k2a, and hydraulic pressure value Pw2bMore than threshold k2b, then controller 12 instruction the second line pump
3 stop up to hydraulic pressure value Pw2aMore than threshold k2aAfterwards, run the second line pump 3 again.
This step is directed to and is more than draw water speed or second water storage of the first line pump 2 because of the speed of drawing water of the second line pump 3
The failure condition that the reasons such as device 5 leak produce.Hydraulic pressure value Pw2aLess than threshold k2a, and hydraulic pressure value Pw2bMore than threshold k2bCan
Reflect that the input of the second line pump 3 cannot extract the water in the second water storage device 5, and the input of the first line pump 2 is still
Water in extraction the first water storage device 4, now controller 12 instruction the second line pump 3 stops defeated up to the second line pump 3
Enter end and can extract the water in the second water storage device 5, it is to avoid the second line pump 3 dallies.
Further, the described control method based on the above-mentioned pumping equipment for drill-hole pumping test, also includes following

If hydraulic pressure value Pw2aMore than standard atmospheric pressure value Pa+ ρ gH, then the stopping of controller 12 instruction the first line pump 2 is up to water
Pressure value Pw2aLess than threshold k2aAfterwards, run the first line pump 2 again.
Wherein, ρ is the density of water, and g is acceleration of gravity, and H is the height of the second hydraulic gage a15 to first spout hole.
This step is directed to and is less than draw water speed or first water storage of the first line pump 2 because of the speed of drawing water of the second line pump 3
Device 4 leak or the first line pump 2 cannot the failure conditions that produce of the reason such as normal work.Hydraulic pressure value Pw2aMore than normal atmosphere
Pressure value Pa+ ρ gH can reflect that the water in the first water storage device 4 has overflowed, and now controller 12 indicates that the first line pump 2 stops
Until the water level decreasing in the first water storage device 4 is to the second hydraulic gage a15, it is to avoid the first line pump 2 flogs a dead horse.
Each technical characteristic of embodiment described above can arbitrarily be combined, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic applied in example is all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope of this specification record.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously

Road is provided with water flow switch, and described water storage device is provided with electric draining valve, and described water flow switch, electric draining valve are respectively
It is electrically connected with controller.
9. a kind of control method based on the pumping equipment being used for drill-hole pumping test as claimed in claim 8, its feature exists
In comprising the following steps：
First hydraulic gage detection hydraulic pressure value Pw1, barometer detection boring in atmospheric pressure value PA1；
Controller obtains hydraulic pressure value Pw1And atmospheric pressure value PA1, according to atmospheric pressure value PA1Given threshold K1, and by hydraulic pressure value Pw1With threshold k1
It is compared, if hydraulic pressure value Pw1More than threshold k1, then controller instruction draws water pump operation；
Second hydraulic gage detection hydraulic pressure value Pw2；
Controller obtains hydraulic pressure value Pw2And standard atmospheric pressure value Pa, according to standard atmospheric pressure value PaGiven threshold K2If, hydraulic pressure value Pw2
More than threshold k2, then pump operation in the middle of controller instruction.
10. the control method based on the pumping equipment tested for drill-hole pumping according to claim 9, its feature exists
In further comprising the steps of：
If hydraulic pressure value Pw1Less than threshold k1, then controller instruction suction pump stopping, and indicate that water flow switch is closed；
If hydraulic pressure value Pw2Less than threshold k2, then controller instruction line pump stopping, and indicate electric draining closing gate.
