Water injecting pipeline work water pressure, numerical value are also 0.6MPa, leakage hydraulic gage can synchronous digital show；
Step 1.3: input timer monitoring time is 1 minute；
Step 1.4: data information in step 1.2 and step 1.3 is input in single-chip microcontroller；
Step 1.5: being separately connected water filling port with external water source pipeline and block capsule water inlet；
Step 2: capsule water filling controls capsule hydraulic pressure, is formed and block hole section；Specifically comprise the following steps:
Step 2.1: the water source switch that connection blocks capsule water inlet is opened, at this time because three-way cock connection capsule blocks pipeline
Channel be to open, therefore form access, water flow flows through pressure sensor, and pressure sensor is by hydraulic pressure information input to single-chip microcontroller
In；
Step 2.2: after single-chip microcontroller handles hydraulic pressure information, water flow being made to block interface outflow from mining hose, water flow passes through
It blocks high pressure resistant pipeline and is gradually filled with capsule and heave；When pressure sensor senses that hydraulic pressure reaches 0.6MPa, single-chip microcontroller control
Three-way cock makes to block the channel closing that pipeline is connected with capsule；If pressure sensor senses that hydraulic pressure is greater than 1MPa, monolithic
Machine controls three-way cock, makes to adjust the channel opening that outlet is connected with closure capsule hydraulic pressure, discharge water pressure release, until hydraulic pressure is less than
1MPa, single-chip microcontroller control three-way cock, make to close with the channel for blocking capsule hydraulic pressure conciliation outlet, capsule closure pipeline is connected,
At this point, capsule is formed in drilling blocks hole section, the water source switch that connection blocks capsule water inlet is closed；
Step 3: drilling rod water filling, monitoring leakage water；Specifically comprise the following steps:
Step 3.1: the water source switch of connection water filling port is opened, at this time because the channel of three-way cock connection leakage water injecting pipeline is
It opens, therefore forms access, water flow flows through pressure sensor and flow sensor, and pressure sensor and flow sensor are by pipeline
Interior hydraulic pressure, flow information are input in single-chip microcontroller；
Step 3.2: after single-chip microcontroller handles hydraulic pressure, flow information, flowing out water flow from mining hose water injection interface, water flow
Drilling rod is flowed through by filling the water high pressure resistant pipeline, injection blocks in hole section in probe in hole；When leakage hydraulic gage shows that hydraulic pressure is super
When crossing 0.6MPa, single-chip microcontroller controls three-way cock, makes to adjust the channel unlatching that outlet is connected with leakage hydraulic pressure, discharges water pressure release extremely
0.6MPa, after hydraulic pressure maintains to stablize, timer starts to carry out test assignment, and records data on flows, time display and leakage
Dehydration meter synchronous digital shows that single-chip microcontroller saves these data in real time, and after one minute, timer times timing, single-chip microcontroller stops
Only data save, and test terminates for the first time；
Step 4: discharge water pressure release, carries out next test；Specifically comprise the following steps:
Step 4.1: after testing for the first time, closing water source switch, open the water proof switch that capsule blocks pipeline, make in capsule
Water outflow, open simultaneously leakage water injecting pipeline cock of water drain, water in pipeline is released；
Step 4.2: starting drilling machine, make test device advance 1m in hole；
Step 4.3: repeating step 1-3, tested and recorded, until completing all tests；
Step 4.4: after entire test process, each flow for will being recorded using external collector from data-out port
Value export.
