[0015] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0016] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0017] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0018] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0019] The beneficial effects of this utility model are:

[0020] 1. This device integrates wear resistance testing and corrosion resistance testing into one testing box. The turbine cylinder body on the placement plate is driven by the first moving block to pass through the wear resistance testing component and the corrosion resistance testing component in sequence, realizing one-stop testing of the wear resistance and corrosion resistance of the cylinder body, which greatly improves the testing efficiency. The placement plate is driven to rotate by the second drive motor, which can adjust the testing angle of the turbine cylinder body, enabling comprehensive testing of different parts of the cylinder body, improving the integrity and reliability of the testing.

[0021] 2. The clamping assembly drives the second threaded rod through the third drive motor, enabling the two clamping plates to stably clamp the turbine cylinder. At the same time, the buffer assembly avoids damage to the cylinder during clamping, ensuring the stability of the cylinder position during testing, thereby improving the accuracy of the test results.

[0022] 3. The pressure sensor in the wear resistance testing component can accurately control the contact pressure between the wear resistance test head and the cylinder surface, and the flow control valve in the corrosion resistance testing component can accurately adjust the spray volume of corrosive liquid.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Wear and corrosion resistant steam turbine cylinder block wear and corrosion resistance testing device, such as Figures 1-5 As shown, the device includes a testing platform 1, with a first groove 2 at the upper end of the testing platform 1, a first threaded rod 3 installed in the first groove 2, and a first drive motor 4 fixedly installed on the side end of the testing platform 1. The output shaft of the first drive motor 4 is fixedly connected to the first threaded rod 3.

[0032] The first movable block 5 is threadedly mounted on the side end of the first threaded rod 3. The first movable block 5 has an internal receiving cavity 6, in which a second drive motor 7 is installed. The output end of the second drive motor 7 is fixedly mounted with a drive gear 8. A placement plate 9 is rotatably mounted on the upper end of the first movable block 5. A support column 10 is fixedly mounted on the lower end of the placement plate 9. The lower end of the support column 10 is rotatably connected to the first movable block 5. A driven gear 11 is fixedly mounted on the side end of the support column 10. The driven gear 11 meshes with the drive gear 8. The first threaded rod 3 is a one-way threaded rod.

[0033] Clamping assembly 12, which is mounted on the upper end of the placement plate 9;

[0034] The test box 13 is fixedly installed on the upper end of the test platform 1. Both ends of the test box 13 are open. The wear-resistant test component 14 and the corrosion-resistant test component 15 are installed in sequence inside the test box 13.

[0035] This device integrates wear resistance testing and corrosion resistance testing into a single testing box 13. The turbine cylinder body on the placement plate 9 is driven by the first moving block 5 to pass sequentially through the wear resistance testing component 14 and the corrosion resistance testing component 15, realizing one-stop testing of the wear resistance and corrosion resistance of the cylinder body and greatly improving testing efficiency. The second drive motor 7 drives the placement plate 9 to rotate, which can adjust the testing angle of the turbine cylinder body, enabling comprehensive testing of different parts of the cylinder body and improving the integrity and reliability of the testing.

[0036] In a preferred embodiment of this utility model, the clamping assembly 12 includes a third drive motor 16, a second threaded rod 17, a second moving block 18, a mounting plate 19, a buffer assembly 20, and a clamping plate 21. A second groove 22 is formed at the upper end of the placement plate 9, and the second threaded rod 17 is installed within the second groove 22. The third drive motor 16 is fixedly mounted on the side end of the placement plate 9, and the output shaft of the third drive motor 16 is fixedly connected to the side end of the second threaded rod 17. Two second moving blocks 18 are symmetrically threaded onto the side end of the second threaded rod 17. A mounting plate 19 is fixedly mounted on the upper end of each second moving block 18, and a buffer assembly 20 is fixedly mounted on the side end of each mounting plate 19. The clamping plate 21 is fixedly mounted on the end of the buffer assembly 20 away from the mounting plate 19. The second threaded rod 17 is a bidirectional threaded rod.

[0037] The clamping assembly 12 mainly consists of a third drive motor 16, a second threaded rod 17, a second moving block 18, a mounting plate 19, a buffer assembly 20, and a clamping plate 21. When clamping the turbine cylinder block, the third drive motor 16 is started, and its output shaft drives the second threaded rod 17 to rotate. Since the second threaded rod 17 has two second moving blocks 18 symmetrically threaded on its side end, according to the principle of threaded transmission, the rotation of the second threaded rod 17 will cause the two second moving blocks 18 to move towards each other. The second moving blocks 18 drive the mounting plate 19 fixed at its upper end to move together, and the mounting plate 19, in turn, drives the clamping plate 21 to move through the buffer assembly 20. Finally, the two clamping plates 21 stably clamp the turbine cylinder block. During the clamping process, the buffer assembly 20 plays an important role. When the clamping plate 21 contacts the cylinder block, the first telescopic rod 27 and the second telescopic rod 28 slide relative to each other, and at the same time, the buffer spring 29 located inside the second telescopic rod 28 is compressed to buffer the clamping force and avoid damage to the cylinder block. The clamping assembly 12 has three main functions: First, it achieves stable clamping of the turbine cylinder body, avoiding inaccurate test results caused by cylinder body shaking or displacement during the testing process, providing a reliable foundation for subsequent wear and corrosion resistance testing, and ensuring the accuracy of the test results. Second, the design of the buffer assembly 20 effectively avoids scratches, indentations, and other damage to the surface of the turbine cylinder body caused by excessive clamping force during the clamping process, protecting the integrity of the cylinder body, which is particularly important for the testing of some high-precision turbine cylinder bodies with high surface quality requirements. Third, through the cooperation of the third drive motor 16 and the second threaded rod 17, it can conveniently and quickly achieve clamping of turbine cylinder bodies of different sizes, improving the versatility and applicability of the device, and meeting the testing needs of cylinder bodies of various specifications.

[0038] As a preferred embodiment of this utility model, limiting grooves 23 are provided on both sides of the first groove 2, and limiting blocks 24 are fixedly installed on the side of the first moving block 5. The limiting blocks 24 are adapted to the limiting grooves 23 and are located within the limiting grooves 23. The first moving block 5 moves along the testing table 1 under the drive of the first threaded rod 3. The limiting blocks 24 are adapted to the limiting grooves 23 and are located within the limiting grooves 23, which can restrict the first moving block 5 to move only along the direction of the limiting grooves 23, preventing the first moving block 5 from shifting laterally or shaking during the movement, and ensuring that the first moving block 5 moves smoothly along a predetermined straight trajectory. This allows the turbine cylinder placed on the first moving block 5 to accurately enter the wear-resistant testing component 14 and the corrosion-resistant testing component 15 in the testing box 13 for testing, ensuring the smooth progress of the testing process.

[0039] In a preferred embodiment of this invention, the upper end of the first moving block 5 is provided with a sliding groove 25, and the lower end of the placement plate 9 is fixedly installed with a slider 26, which is adapted to the sliding groove 25. When the second drive motor 7 drives the placement plate 9 to rotate through the meshing of the drive gear 8 and the driven gear 11, the slider 26 can slide flexibly within the sliding groove 25. This design reduces the frictional resistance during the rotation of the placement plate 9, allowing it to rotate more smoothly and steadily. Compared to a structure without the slider 26 and the sliding groove 25, the placement plate 9 will not experience jamming due to poor rotation, thus ensuring the smoothness of the angle adjustment for the turbine cylinder inspection and providing a good foundation for comprehensive inspection of different parts of the cylinder.

[0040] In a preferred embodiment of this utility model, the buffer assembly 20 includes a first telescopic rod 27, a second telescopic rod 28, and a buffer spring 29. One end of the first telescopic rod 27 is fixedly connected to the side end of the mounting plate 19, and one end of the second telescopic rod 28 is fixedly connected to the side end of the clamping plate 21. The other end of the first telescopic rod 27 is sleeved with the other end of the second telescopic rod 28. The outer diameter of the second telescopic rod 28 is equal to the inner diameter of the first telescopic rod 27. The buffer spring 29 is located inside the second telescopic rod 28, and both ends of the buffer spring 29 are fixedly connected to the sides of the mounting plate 19 and the clamping plate 21, respectively. The design of the buffer assembly 20 effectively avoids scratches, indentations, and other damage to the surface of the turbine cylinder body caused by excessive clamping force during clamping, protecting the integrity of the cylinder body. This is particularly important for the inspection of turbine cylinder bodies with high precision and high surface quality requirements.

[0041] As a preferred embodiment of this utility model, the wear resistance testing component 14 includes a first hydraulic telescopic rod 30, a mounting block 31, a wear resistance testing head 32, and a pressure sensor 33. The first hydraulic telescopic rod 30 is fixedly installed on the inner side wall of the testing box 13. The mounting block 31 is fixedly installed on the telescopic end of the first hydraulic telescopic rod 30. The wear resistance testing head 32 is fixedly installed on the end of the mounting block 31 away from the first hydraulic telescopic rod 30. The pressure sensor 33 is fixedly installed on the side end of the mounting block 31 through an L-shaped bracket 34. The L-shaped bracket 34 is fixedly connected to the upper end of the mounting block 31, and the pressure sensor 33 is fixedly installed on the side end of the L-shaped bracket 34.

[0042] The wear resistance testing component 14 mainly includes a wear resistance test head 32 and a pressure sensor 33, which are tightly connected and work together to test the wear resistance of the turbine cylinder surface. The wear resistance test head 32 is made of a special alloy material with high strength and high wear resistance. Its shape is designed to be a suitable circular or flat shape according to the common surface structure of the turbine cylinder and the testing requirements, so as to ensure full contact with the cylinder surface and conduct effective friction testing.

[0043] The pressure sensor 33 is a high-precision strain gauge pressure sensor, which features high sensitivity and a wide measurement range, and can accurately detect the pressure when the wear-resistant test head 32 contacts the surface of the turbine cylinder. The pressure sensor 33 is fixedly mounted on the L-shaped bracket 34, and is connected to an external data processing system via a data cable, enabling it to transmit the detected pressure data to the data processing system in real time.

[0044] During wear resistance testing, the wear-resistant test head 32 moves along a preset path on the surface of the turbine cylinder block. During this friction process, the pressure sensor 33 monitors the pressure between the wear-resistant test head 32 and the cylinder block surface in real time and feeds the pressure data back to the data processing system. Simultaneously, by observing the wear condition of the wear-resistant test head 32 itself and combining this data with the data from the pressure sensor 33, the data processing system performs calculations and analysis to accurately assess the wear resistance of the turbine cylinder block surface.

[0045] As a preferred embodiment of this utility model, the corrosion-resistant testing component 15 includes a storage tank 35, a delivery pipeline 36, an atomizing nozzle 37, a flow control valve 38, a second hydraulic telescopic rod 39, and a testing probe 40. The second hydraulic telescopic rod 39 is fixedly installed on the inner side wall of the testing box 13, and the testing probe 40 is fixedly installed on the telescopic end of the second hydraulic telescopic rod 39. The storage tank 35 is fixedly installed on the upper end of the testing box 13. One end of the delivery pipeline 36 is connected to the bottom of the storage tank 35. The atomizing nozzle 37 is fixedly installed inside the testing box 13, and the upper end of the atomizing nozzle 37 is sealed to the lower end of the delivery pipeline 36. The flow control valve 38 is installed on the side of the delivery pipeline 36.

[0046] The corrosion resistance testing unit mainly consists of a spray device and a testing probe 40. The spray device includes a storage tank 35, a delivery pipeline 36, an atomizing nozzle 37, and a flow control valve 38. The storage tank 35 is used to store corrosive liquids of specific concentrations, such as common acid and alkali solutions. It is made of high-strength, corrosion-resistant engineering plastic and has good sealing properties to prevent the corrosive liquid from evaporating and leaking. The delivery pipeline 36 is made of corrosion-resistant PVC. One end is connected to the outlet of the storage tank 35, and the other end is connected to the atomizing nozzle 37, used to deliver the corrosive liquid in the storage tank 35 to the atomizing nozzle 37. The atomizing nozzle 37 is installed inside the testing chamber 13 to ensure that the corrosive liquid can be sprayed evenly on the surface of the chamber. The flow control valve 38 is installed on the delivery pipeline 36. By adjusting the valve opening, the flow rate and spraying speed of the corrosive liquid can be precisely controlled to simulate corrosive environments of different intensities.

[0047] The detection probe 40 is a high-precision electrochemical corrosion detection probe. Its working principle is based on electrochemical corrosion, enabling real-time detection of the corrosion potential and corrosion current on the turbine cylinder surface after exposure to corrosive liquids. The detection probe 40 makes direct contact with the cylinder surface via a probe made of high-purity platinum, which possesses excellent conductivity and corrosion resistance. The detection probe 40 connects to an external data acquisition and analysis system via a data cable, transmitting the detected corrosion potential and corrosion current data to the system in real time. The data acquisition and analysis system incorporates professional corrosion analysis software, which processes and analyzes the transmitted data in real time. By calculating and comparing standard data, it determines corrosion resistance performance indicators such as corrosion rate and corrosion depth on the turbine cylinder surface.

[0048] During corrosion resistance testing, the spraying parameters of the spray device are first adjusted via the flow control valve 38, causing the atomizing nozzle 37 to uniformly spray corrosive liquid onto the surface of the turbine cylinder block, simulating an actual corrosive environment. During spraying, the detection probe 40 monitors the corrosion status of the cylinder block surface in real time and transmits the data to the data acquisition and analysis system. The data acquisition and analysis system processes and analyzes the data in real time, plotting a corrosion change curve of the cylinder block surface. This visually demonstrates the performance changes of the cylinder block during corrosion, thereby accurately assessing the corrosion resistance of the turbine cylinder block surface.

[0049] Working principle and usage process of this utility model:

[0050] When using the wear-resistant and corrosion-resistant turbine cylinder block testing device of the present invention, the turbine cylinder block is first placed on the placement plate 9. The third drive motor 16 is started, which drives the second threaded rod 17 to rotate, causing the two second moving blocks 18 to move towards each other. The buffer assembly 20 drives the clamping plate 21 to stably clamp the turbine cylinder block. Then, the first drive motor 4 is started, which drives the first threaded rod 3 to rotate, causing the first moving block 5 to move along the testing table 1, and sending the clamped turbine cylinder block into the testing box 13.

[0051] After the turbine cylinder body enters the testing chamber 13, its wear resistance is tested first. The first hydraulic telescopic rod 30 is activated, which pushes the mounting block 31 and the wear resistance test head 32 into contact with the surface of the turbine cylinder body. The pressure sensor 33 monitors the contact pressure in real time and feeds it back to the control system. The control system adjusts the extension and retraction of the first hydraulic telescopic rod 30 according to the set pressure value, so that the wear resistance test head 32 performs a friction test with the cylinder body surface at an appropriate pressure, thereby testing the wear resistance of the cylinder body.

[0052] After the wear resistance test is completed, the first moving block 5 continues to move, bringing the turbine cylinder into the corrosion resistance test area. The flow control valve 38 is opened, and the corrosive liquid in the storage tank 35 is atomized through the delivery pipe 36 and sprayed onto the surface of the turbine cylinder by the atomizing nozzle 37. Simultaneously, the second hydraulic telescopic rod 39 is activated, driving the detection probe 40 to detect the corrosion on the cylinder surface. The corrosion resistance of the cylinder is determined based on the test results.

[0053] During the entire inspection process, if different parts of the turbine cylinder block need to be inspected, the second drive motor 7 can be started. The second drive motor 7 drives the placement plate 9 to rotate through the meshing of the drive gear 8 and the driven gear 11, adjusting the inspection angle of the cylinder block, and then the inspection continues. After the inspection is completed, the first moving block 5 moves the turbine cylinder block out of the inspection box 13, closes all drive motors and valves, removes the inspected cylinder block, and completes one inspection operation.
