Hydraulic pressure value Pw2aMore than threshold k2a, then controller 12 indicate the first line pump 2 run；
Second hydraulic gage b16 detection hydraulic pressure values Pw2b；
Controller 12 obtains hydraulic pressure value Pw2b, according to standard atmospheric pressure value PaGiven threshold K2bIf hydraulic pressure value Pw2bMore than threshold
Value K2b, then controller 12 indicate the second line pump 3 run.
The above-mentioned control method based on the pumping equipment tested for drill-hole pumping, hydraulic pressure value Pw1More than threshold k1Drill
Interior water had not had the input of suction pump 1, and controller 12 indicates that suction pump 1 is run, hydraulic pressure value Pw2aMore than threshold k2aI.e. first
Water in water storage device 4 had not had the input of the first line pump 2, and controller 12 indicates that the first line pump 2 is run, hydraulic pressure value
Pw2bMore than threshold k2bWater i.e. in the second water storage device 5 had not had the input of the second line pump 3, the instruction of controller 12 second
Line pump 3 is run, and can ensure that the water in drilling is smoothly extracted out.
In the present embodiment, threshold k1For atmospheric pressure value PA11.00-1.02 times, when water did not had the first hydraulic gage 14, take out
Water pump 1 is run at once, high sensitivity.Threshold k2aFor standard atmospheric pressure value Pa1.00-1.02 times, do not had the second hydraulic pressure in water
When counting a15, the first line pump 2 is run at once, high sensitivity.Threshold k2bFor standard atmospheric pressure value Pa1.00-1.02 times,
When water did not had the second hydraulic gage b16, the second line pump 3 is run at once, high sensitivity.
Further, the control method based on the above-mentioned pumping equipment for drill-hole pumping experiment, in addition to it is following
Step：
If hydraulic pressure value Pw1Less than threshold k1, then controller 12 indicates that suction pump 1 stops, and indicates that water flow switch 17 is closed；
If hydraulic pressure value Pw2aLess than threshold k2a, then controller 12 indicates that the first line pump 2 stops, and indicates electric draining lock
Door a is closed；
If hydraulic pressure value Pw2bLess than threshold k2b, then controller 12 indicates that the second line pump 3 stops, and indicates electric draining lock
Door b is closed.
This step is exhausted for the water in drilling there is dry situation.Hydraulic pressure value Pw1Less than threshold k1That is suction pump 1
Input can not extract drilling in water, controller 12 indicate suction pump 1 stop, preventing suction pump 1 from dallying.Hydraulic pressure value
Pw2aLess than threshold k2aI.e. the input of the first line pump 2 can not 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 k2bThat is the input of the second line pump 3
The water in the second water storage device 5 can not have been extracted, and controller 12 indicates that the second line pump 3 stops, and prevents that the second line pump 3 is empty
Turn.
Further, the control method based on the above-mentioned pumping equipment for drill-hole pumping experiment, in addition to it is following
Step：
If hydraulic pressure value Pw1More than threshold k1, and hydraulic pressure value Pw1With atmospheric pressure value PA1Difference in setting time T0Interior holding is not
Become, then controller 12 indicates that suction pump 1 runs setting time T1After stop, and indicate water flow switch 17 close；
If hydraulic pressure value Pw2aLess than threshold k2a, then controller 12 indicates that the first line pump 2 stops, and indicates electric draining lock
Door a is closed；
If hydraulic pressure value Pw2bLess than threshold k2b, then controller 12 indicates that the second line pump 3 stops, and indicates electric draining lock
Door b is closed.
This step is maintained at the situation of a certain height for the water drawdown in drilling for a long time.Hydraulic pressure value Pw1With air pressure
Value PA1Difference can reflect that drawdown is constant, now controller 12 indicates that suction pump 1 runs setting time T1After stop,
Then the first line pump 2, the second line pump 3 stop in succession, terminate drill-hole pumping experiment.
Further, the control method based on the above-mentioned pumping equipment for drill-hole pumping experiment, in addition to it is following
Step：
If hydraulic pressure value Pw2aLess than threshold k2a, and hydraulic pressure value Pw2bMore than threshold k2b, then controller 12 indicate the second line pump
3 stop until hydraulic pressure value Pw2aMore than threshold k2aAfterwards, the second line pump 3 is run again.
This step is directed to because the speed of drawing water of the second line pump 3 is more than draw water speed or the second water storage of the first line pump 2
The failure situation caused by reason such as leak of device 5.Hydraulic pressure value Pw2aLess than threshold k2a, and hydraulic pressure value Pw2bMore than threshold k2bCan
The water in the second water storage device 5 can not have been extracted by reflecting the input of the second line pump 3, and the input of the first line pump 2 is still
The water in the first water storage device 4 is being extracted, the stopping of second line pump 3 of the now instruction of controller 12 is defeated up to the second line pump 3
Enter to hold the water that can be extracted in the second water storage device 5, avoid the second line pump 3 from dallying.
Further, the control method based on the above-mentioned pumping equipment for drill-hole pumping experiment, in addition to it is following
Step：
If hydraulic pressure value Pw2aMore than standard atmospheric pressure value Pa+ ρ gH, then the stopping of first line pump 2 of the instruction of controller 12 is until water
Pressure value Pw2aLess than threshold k2aAfterwards, the first line pump 2 is run again.
Wherein, ρ is the density of water, and g is acceleration of gravity, and H is the second hydraulic gage a15 to the first spout hole height.
This step is directed to because the speed of drawing water of the second line pump 3 is less than draw water speed or the first water storage of the first line pump 2
The leak of device 4 or the first line pump 2 can not the failure situations caused by reason such as normal work.Hydraulic pressure value Pw2aMore than normal atmosphere
Pressure value PaThe water that+ρ gH can reflect in the first water storage device 4 has overflowed, and now controller 12 indicates that the first line pump 2 stops
At the water level decreasing in the first water storage device 4 to the second hydraulic gage a15, the first line pump 2 is avoided to flog a dead horse.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
