Embodiment 1

[0043] Please refer to the attached figure 1 , this embodiment includes a water supply system, a water pressure regulating system, a data acquisition system, a data processing system, and an embolism pressure supply system, the water supply system, the data acquisition system, and the embolism pressure supply system are connected to each other, and the data processing system is connected to the data acquisition system system.

[0044] In this embodiment, the water supply system includes an engine 2, a coupling 3, a water supply pump 4, a water supply storage tank 5, a water supply suction filter 6, a safety valve 7, a pressure stabilizing tank 8, a water supply outlet filter 9 and a pressure water pipe Hoisting 19, one end of the engine 2 is connected to the data acquisition system, the other end of the engine 2 is connected to the coupling 3, the water supply pump 4, the safety valve 7, the surge tank 8 and the water supply and outlet filter 9 are connected to each other, so ...

Embodiment 2

[0087] Refer to attached figure 2 , Figure 9-Figure 11 , The difference between this embodiment and Embodiment 1 is that the electric proportional pressure regulating valve 12 adopts an electric proportional overflow valve, and the rest are basically the same as Embodiment 1.

[0088] The high degree of intelligence improves the work efficiency, reduces the labor intensity of the operator, and improves the accuracy of the test results; the data accuracy is high; the output flow of the water pump is stable, and the pressure regulator tank and the electric proportional pressure regulating valve in the water supply system are in good condition. It has the function of voltage stabilization; light in weight; the software authority is classified and managed, and the test test data is supervised; it provides a complete set of solutions for the drilling water pressure test process, with high integration; the operation is simple and convenient.

Embodiment 3

[0090] Refer to attached image 3 , Figure 9-Figure 11 , The difference between this embodiment and Embodiment 1 is that the electric proportional pressure regulating valve 12 adopts an electric proportional pressure reducing valve, and the rest are basically the same as Embodiment 1.

[0091] The high degree of intelligence improves the work efficiency, reduces the labor intensity of the operator, and improves the accuracy of the test results; the data accuracy is high; the output flow of the water pump is stable, and the pressure regulator tank and the electric proportional pressure regulating valve in the water supply system are in good condition. It has the function of voltage stabilization; light in weight; the software authority is classified and managed, and the test test data is supervised; it provides a complete set of solutions for the drilling water pressure test process, with high integration; the operation is simple and convenient.

Description

technical field [0001] The invention relates to borehole pressure water test equipment, in particular to an intelligent borehole pressure water test equipment. technical background [0002] The pressure water test is an in-situ test that presses pressure water (generally within 1MPa) into the borehole, and calculates the development of rock mass fissures and water permeability according to the water absorption of the rock mass (generally within 100L / min). Pressurized water test uses special water-stop equipment to isolate a certain length of drilling test section, and then uses fixed water pressure to press water into this section of drilling, and the water penetrates into the rock through the cracks around the hole wall, and finally penetrates The amount of water will tend to a stable value. According to the water pressure, the length of the test section and the steady infiltration of water, the strength of the rock mass permeability can be determined. [0003] In the exi...
