Being described by the structure of the above-mentioned induction osmotic pressure loading device 10 to for In Rock Seepage Tests can
Know, it is comprised the following steps that：
Step 1：Start unidirectional variable pump 300, when the operating position of three-position four-way electromagnetic directional valve 500 is in middle position,
Double acting pressurized cylinder 600 is locked, and the pipeline in each oil circuit and water route does not work, standby.
Step 2：When the left position of three-position four-way electromagnetic directional valve 500 is connected, the first fuel tank 200 starts fuel feeding, and fluid leads to
Cross the first oil pocket 630 that the first oil pipe 21 enters double acting pressurized cylinder 600.Piston rod 650 is moved right, now, the first water cavity
610 volumes increase, the water supply start of water tank 100, and water flows through the first check valve 110 and enters the first water cavity 610 along the first water pipe 11,
Until the first water cavity 610 is full of water.Meanwhile, the volume of the second water cavity 620 reduces, and water flows through the 4th check valve 140 and supplied along second
Water pipe 14 is by accumulator 701, pressure sensor 702 and flow sensor 703 are into permeameter 700 and act on permeameter
The rock tested in 700.
Step 3：When first piston 660 moves right the position to the second self-induction type sensor 502, the second self-induction type is passed
Sensor 502 sends control signal, is transferred to three-position four-way electromagnetic directional valve 500, the turn on automatically of three-position four-way electromagnetic directional valve 500
To right position.
Step 4：Three-position four-way electromagnetic directional valve 500 is switched to right position, during piston rod 650 is to left movement, first
Fluid in oil pocket 630 flows through the first oil pipe 21, three-position four-way electromagnetic directional valve 500 and is back to the 3rd fuel tank, meanwhile, the first oil
Fluid in case 200 then passes through the second oil pipe 22, into the second oil pocket 640 of double acting pressurized cylinder 600.Now, the second water cavity
620 volumes increase, the water supply start of water tank 100, and water flows through the second check valve 120 and enters the second water cavity 620 along the second water pipe 12,
Until the second water cavity 620 is full of water.Meanwhile, the volume of the first water cavity 610 reduces, and water flows through the 3rd check valve 130 and supplied along first
Water pipe 13 continues into permeameter 700 and continues to act on by accumulator 701, pressure sensor 702 and flow sensor 703
The rock tested in permeameter 700.
Step 5：When first piston 660 moves to the position of the first self-induction type sensor 501 to the left, the first self-induction type is passed
Sensor 501 sends control signal, is transferred to three-position four-way electromagnetic directional valve 500, the turn on automatically of three-position four-way electromagnetic directional valve 500
To left position.Now, during piston rod 650 is moved right, the fluid in the second oil pocket 640 flows through 22, three, the second oil pipe
Four-way electromagnetic reversing valve 500 is back to the 3rd fuel tank.
Step 6：Repeat step 2 realizes automatic, lasting water supply, until completing the permeability test of rock to step 5.
Step 7：When system is blocked, loine pressure rises, and overflow valve 820 is opened, and unidirectional variable pump 300 is unloaded,
Ensure the security of whole system work.
In sum, the induction osmotic pressure loading device for In Rock Seepage Tests passes through double acting pressurized cylinder
The effect that double water routes automatic interaction supplies water, draws water is realized, the double water using self-induction type sensor control double acting pressurized cylinder leads to
Road automatically switches, automatic water source supply, solves when being controlled by pump works, oil pump station and syringe type energy storage device originally halfway
The drawbacks of water supply is interrupted；Simultaneously using the electromagnetic control apparatus in double acting pressurized cylinder and oil pump station, realize a pipeline and supply
