Description

Technical Field

[0001] This utility model relates to the technical field of high-pressure deformation testing equipment for rock masses, and in particular to a high-pressure oil pump stabilizing device that resists the influence of rock mass deformation. Background Technology

[0002] In high-pressure deformation tests of rock masses, a high-pressure oil pump is typically used to provide stable oil pressure, which is then applied to the rock mass via jacks to study its deformation characteristics under high pressure. However, in actual operation, the rock mass continuously deforms under high pressure, causing the oil pump pressure to drop continuously, thus affecting the accuracy of the test results. Furthermore, the electric oil pump generates impact pressure during operation, which can also interfere with the test results.

[0003] To address the aforementioned issues, existing technologies typically employ complex control systems to stabilize oil pressure. However, these control systems are often costly and complex to operate. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a high-pressure oil pump stabilizing device that can reduce the impact pressure generated by the operation of the high-pressure oil pump, compensate for the pressure drop of the high-pressure oil pump caused by rock deformation, ensure stable oil pressure during the test, and has a simple structure, low cost, and convenient operation.

[0005] The technical solution of this utility model for a high-pressure oil pump stabilizing device to resist the influence of rock mass deformation is as follows: it includes high-pressure steel pipes made of high-strength alloy steel, there are two or more high-pressure steel pipes, each high-pressure steel pipe has a threaded end at both ends, and each high-pressure steel pipe is connected to a hydraulic pipeline. The high-pressure steel pipes are connected to the hydraulic pipelines through the threaded ends. One end of the first high-pressure steel pipe is connected to the output end of the high-pressure oil pump, and one end of the last high-pressure steel pipe is connected to the input end of the jack.

[0006] Furthermore, a pressure gauge is installed between the jack and the last high-pressure steel pipe.

[0007] Furthermore, the high-pressure oil pump is an electric oil pump.

[0008] Furthermore, the jack is a hydraulic jack.

[0009] Furthermore, the high-pressure steel pipe has a length L of 1m, a wall thickness T of 10mm, and an internal bore diameter Φ of 20mm.

[0010] The beneficial effects of this utility model of a high-pressure oil pump stabilizing device for resisting the influence of rock mass deformation are:

[0011] 1. By connecting high-pressure steel pipes in series to form a pressure stabilizing device, the impact pressure generated by the operation of the high-pressure oil pump can be reduced, and the pressure drop of the high-pressure oil pump caused by rock deformation can be compensated, thus ensuring stable oil pressure during the test.

[0012] Second, the device has a simple structure, low cost, convenient operation, and is easy to maintain and manage.

[0013] Third, high-pressure steel pipes made of high-strength alloy steel have high strength and stability, and can withstand large pressure without deformation or rupture.

[0018] This utility model relates to a high-pressure oil pump pressure stabilizing device that resists the influence of rock mass deformation, such as... Figure 1 — Figure 2 As shown, it includes a high-pressure steel pipe 1 made of high-strength alloy steel. There are two or more high-pressure steel pipes 1. Each high-pressure steel pipe 1 has a screw end 2 at both ends. Each high-pressure steel pipe 1 is connected to a hydraulic pipeline 3. The high-pressure steel pipe 1 is connected to the hydraulic pipeline 3 through the screw end 2. One end of the first high-pressure steel pipe 1 is connected to the output end of the high-pressure oil pump 4, and one end of the last high-pressure steel pipe 1 is connected to the input end of the jack 5.

[0019] Furthermore, a pressure gauge 6 is installed between the jack 5 and the last high-pressure steel pipe 1. The pressure gauge 6 is a high-precision pressure gauge to ensure that the oil pressure value read is accurate and reliable. The high-precision pressure gauge has high measurement accuracy and stability, and can accurately reflect the oil pressure inside the pipeline, thus ensuring the accuracy of the test results.

[0020] Furthermore, the high-pressure oil pump 4 is an electric oil pump. The high-pressure oil pump 4 is used to provide a stable high-pressure oil source. The electric oil pump has the advantages of simple structure, convenient operation, and easy control, and can meet the requirements of high-pressure oil source in the experiment.

[0021] Furthermore, the jack 5 is a hydraulic jack. Jack 5 is used to generate sufficient jacking force under the action of high-pressure oil. Hydraulic jacks have advantages such as compact structure, large jacking force, and good stability, and can meet the jacking force requirements in the experiment.

[0022] Furthermore, the high-pressure steel pipe 1 has a length L of 1m, a wall thickness T of 10mm, and an internal aperture Φ of 20mm.

[0023] This utility model discloses a high-pressure oil pump stabilizing device to resist the influence of rock mass deformation. It mainly consists of two or more high-pressure steel pipes 1 made of high-strength alloy steel installed between the high-pressure oil pump 4 and the jack 5. Each high-pressure steel pipe 1 has a threaded joint 2 at both ends. The high-pressure steel pipes 1 are connected in series with oil pressure pipelines 3 through the threaded joints 2, forming a continuous oil pressure transmission channel. In the series connection of multiple high-pressure steel pipes 1, the first high-pressure steel pipe 1 is connected to the output end of the high-pressure oil pump 4, and the last high-pressure steel pipe 1 is connected to the input end of the jack 5. During the test, the high-pressure oil pump 4 pumps high-pressure oil through the first high-pressure steel pipe... The high-pressure oil is fed into the jack 5 through the last high-pressure steel pipe 1 after buffering and stabilizing the flow. Simultaneously, the pressure gauge 6 monitors the oil pressure inside the pipeline in real time to ensure stable oil pressure during the test. When the rock mass deforms under high pressure, the pressure of the high-pressure oil pump 4 drops. At this time, the series connection and buffering effect of the high-pressure steel pipes 1 compensate for the pressure drop, maintaining stable oil pressure. Furthermore, the high-pressure steel pipes 1 reduce the impact pressure generated by the high-pressure oil pump, further ensuring stable oil pressure during the test. This solution is a high-pressure oil pump stabilizing device to resist the influence of rock mass deformation. By forming a stabilizing device with series high-pressure steel pipes 1, it can reduce the impact pressure generated by the high-pressure oil pump 4 and compensate for the pressure drop caused by rock mass deformation, ensuring stable oil pressure during the test. The overall structure is simple, low-cost, easy to operate, maintain, and manage. It is suitable for various high-pressure deformation tests on rock masses, improving the accuracy and reliability of test results.
