DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings and embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] like Figures 1 to 4 As shown, a thin-walled stainless steel water pipe pressure test equipment includes a base plate 1, a test water pipe 4 is arranged above the base plate 1, the test water pipe 4 is slidably connected to the inside of the limit sleeve 3, and a test mechanism 5 is arranged at the right end of the test water pipe 4. The test mechanism 5 includes a square cylinder 501 and a square rod 505. A contact sensor 506 is fixedly installed inside the square rod 505, and a mounting plate 507 is fixedly installed on the end of the square rod 505 away from the square cylinder 501. A distance sensor 508 is fixedly installed on the mounting plate 507. The distance sensor 508 is used to measure the distance to the inner wall of the test water pipe 4, so that after driving, the contact sensor 506 is close to the inner wall of the test water pipe 4 but does not contact its inner wall.
[0021] The square tube 501 is fixedly mounted on the vertical plate 7 , the vertical plate 7 is fixedly mounted on the bottom plate 1 , a reduction motor 502 is fixedly mounted on the square tube 501 , and a bidirectional lead screw 503 is fixedly mounted on the output end of the reduction motor 502 .
[0022] The bidirectional screw rod 503 is rotatably connected to the interior of the square tube 501 , and a slider 504 is threadedly connected to the bidirectional screw rod 503 .
[0023] The slider 504 is slidably connected to the inner wall of the square tube 501 , and the slider 504 is fixedly connected to one end of the square rod 505 away from the distance measuring sensor 508 .
[0024] A U-shaped frame 6 is fixedly installed on the upper surface of the base plate 1, an electric push rod 8 is fixedly installed on the inner wall of the U-shaped frame 6, a clamping plate 9 is fixedly installed on one end of the electric push rod 8 close to the test water pipe 4, and a pressure sensor 10 is fixedly installed on one side of the clamping plate 9 close to the test water pipe 4.
[0025] The support frame 2 is fixedly mounted on the limiting sleeve 3 , and the support frame 2 is fixedly mounted on the base plate 1 .
[0026] like Figures 1 to 4 As shown, in some embodiments, two support frames 2 and two limiting sleeves 3 are provided, both disposed above the base plate 1, and are used together to limit the position of the test water pipe 4. Two electric push rods 8, clamping plates 9, and pressure sensors 10 are provided, all symmetrically disposed on the U-shaped frame 6. These two sets of clamping assemblies can simultaneously perform clamping tests on the test water pipe 4. Two sliders 504, square rods 505, contact sensors 506, mounting plates 507, and distance sensors 508 are provided, all disposed on the bidirectional screw 503. These two sets of testing assemblies are used to simultaneously test the inner wall of the test water pipe 4, such that, after actuation, the contact sensors 506 are close to the inner wall of the test water pipe 4 but do not contact it.
[0027] like Figures 1 to 4 As shown, in some embodiments, the thin-walled stainless steel water pipe pressure testing equipment includes components such as a base plate 1, a support frame 2, a limit sleeve 3, a test water pipe 4, a test mechanism 5, a U-shaped frame 6, an electric push rod 8, a clamping plate 9 and a pressure sensor 10.
[0028] During implementation, the test water pipe 4 to be tested is first placed inside the two limiting sleeves 3 , and the two limiting sleeves 3 are fixed on the bottom plate 1 through two supporting frames 2 respectively to ensure the stability of the test water pipe 4 .
[0029] Then, one end of the test water pipe 4 is pushed toward the test mechanism 5. The test mechanism 5 comprises a square cylinder 501 and a square rod 505. A contact sensor 506 is fixedly mounted inside the square rod 505. A mounting plate 507 is fixedly mounted on the end of the square rod 505 away from the square cylinder 501, and a distance sensor 508 is fixedly mounted on the mounting plate 507.
[0030] Next, the two electric push rods 8 on the U-shaped frame 6 are activated, and the two electric push rods 8 respectively push the two clamping plates 9 toward the test water pipe 4 until the pressure sensors 10 on the clamping plates 9 contact the outer wall of the test water pipe 4. At this point, no further pressure is applied, and the test water pipe 4 is simply clamped firmly.
[0031] Then, the reduction motor 502 mounted on the square tube 501 is started. The reduction motor 502 drives the bidirectional screw rod 503 to rotate inside the square tube 501. Since the bidirectional screw rod 503 is threadedly connected to the slider 504, and the slider 504 is slidably connected to the inner wall of the square tube 501, the slider 504 moves along the axial direction of the bidirectional screw rod 503 as it rotates.
[0032] The movement of the slider 504 drives the square rod 505 and its mounting plate 507 at one end toward the inner wall of the test water pipe 4. During this process, the distance sensor 508 on the mounting plate 507 continuously measures the distance to the inner wall of the test water pipe 4 to ensure that the contact sensor 506 inside the square rod 505 can be close to the inner wall of the test water pipe 4 without directly contacting it.
[0033] When the contact sensor 506 is close to the inner wall of the test water pipe 4, the electric push rod 8 starts to apply thrust, which puts pressure on the test water pipe 4. At the same time, the pressure sensor 10 starts to monitor and record the pressure data on the outer wall of the test water pipe 4.
[0034] Through the above-described implementation, the thin-walled stainless steel water pipe compression testing equipment of this embodiment enables simultaneous, high-precision monitoring of both the outer wall pressure and inner wall deformation of the water pipe. Pressure sensor 10 monitors outer wall pressure, while contact sensor 506 monitors inner wall deformation. This dual monitoring approach effectively improves test accuracy and efficiency, meeting the high-precision testing requirements for thin-walled stainless steel water pipes, a material often used for water pipes made of specialized materials.
[0035] Working Principle: During use, the test pipe 4 to be tested is first placed inside the retaining sleeve 3, which is secured to the base plate 1 via the support frame 2 to ensure the pipe's stability. Subsequently, one end of the test pipe 4 is pushed onto the testing mechanism 5. The electric push rod 8 on the U-shaped frame 6 is activated, pushing the clamping plate 9 toward the test pipe 4 until the pressure sensor 10 on the clamping plate 9 contacts the outer wall of the test pipe 4. At this point, no further pressure is applied, only the test pipe 4 is firmly clamped. The reduction motor 502 mounted on the square cylinder 501 is then activated. The reduction motor 502 drives the bidirectional screw 503 to rotate within the square cylinder 501. Because a slider 504 is threadedly connected to the bidirectional screw 503 and slidably connected to the inner wall of the square cylinder 501, the slider 504 moves axially along the rotation of the bidirectional screw 503. This movement of the slider 504 drives the square rod 505 and its mounting plate 507 at one end toward the inner wall of the test pipe 4. The distance sensor 508 fixedly mounted on the mounting plate 507 continuously measures the distance to the inner wall of the test water pipe 4 during movement to ensure that the contact sensor 506 inside the square rod 505 can be close to the inner wall of the test water pipe 4 but not in direct contact with it. In this way, the contact sensor 506 can accurately monitor the deformation of the water pipe during the pressure process without damaging the inner wall of the water pipe. At this time, the thrust of the electric push rod 8 is applied, and then the pressure sensor 10 begins to monitor and record the pressure data. In this way, the thin-walled stainless steel water pipe compression test equipment of the present invention can achieve synchronous and high-precision monitoring of the outer wall pressure and inner wall deformation of the water pipe, thereby effectively improving the test accuracy and efficiency and meeting the high-precision testing requirements of thin-walled stainless steel water pipes, such as special material water pipes.
