Description

Technical Field

[0001] This invention belongs to the technical field of wear testing devices, specifically relating to an erosion wear testing device. Background Technology

[0002] Pneumatic conveying of granules can be used to collect and process dust generated during industrial production, as well as to transport granular raw materials and finished products. Because conveying systems operate under high pressure, high temperature, and high concentrations of particles for extended periods, pipeline erosion and wear are severe problems. This is particularly true in industrial sectors such as wastewater and sewage treatment, where large amounts of sludge or sediment require pipeline systems for transport or treatment. During sludge treatment, the substances within the pipeline form a three-phase flow (gas, liquid, and solid), and the entrained solid particles can cause severe erosion and wear damage to the pipeline system. Therefore, the erosion rate of pipelines and equipment caused by solid particles entrained in multiphase flow has always been a focus of attention.

[0003] Existing erosion and wear testing devices are relatively simple, generally single-phase flow (solid, gas, liquid) or multi-phase flow (gas, solid, liquid). Among them, multi-phase flow devices have complex structures to ensure the stability of the test and to prevent the medium in the pipeline from flowing back into other pipelines. Moreover, existing multi-phase flow devices cannot achieve erosion and wear tests with different solids in parallel or selectively combined with liquids and / or gases. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a multiphase flow erosion and wear testing device that is stable in performance, simple in structure, capable of performing single-phase or multiphase flow erosion and wear tests, and capable of performing erosion and wear tests on different solids in parallel or selectively in combination with liquids and / or gases.

[0005] The objective of this invention can be achieved through the following technical solution: an erosion wear testing device, comprising:

[0006] The storage module includes a first single-phase storage component, a two-phase storage component, and a second single-phase storage component;

[0007] The erosion module is connected to the first single-phase storage component, the two-phase storage component and the second single-phase storage component respectively through connecting pipes. A first pipeline is formed between the erosion module, the connecting pipe and the first single-phase storage component, a second pipeline is formed between the erosion module, the connecting pipe and the two-phase storage component, and a third pipeline is formed between the erosion module, the connecting pipe and the second single-phase storage component.

[0008] A shut-off valve, disposed on a connecting pipe, is used to open or close the connecting pipe. It includes a first shut-off valve disposed on a first pipe and a second shut-off valve disposed on a second pipe.

[0009] When any one or more of the first shut-off valve and the second shut-off valve are opened or closed, the first single-phase storage component and the two-phase storage component corresponding to the first and the second shut-off valves are connected or disconnected from the erosion module, so that the medium in the first single-phase storage component, the two-phase storage component and the second single-phase storage component flows to the erosion module individually or simultaneously through the corresponding first pipeline, the second pipeline or the third pipeline, so as to realize the single-phase flow or multi-phase flow erosion wear test.

[0010] In the aforementioned erosion and wear testing device, the first shut-off valve is located on the side of the first pipeline near the erosion module, and the second shut-off valve is located on the side of the second pipeline near the erosion module. When the first shut-off valve is closed, it forms a barrier on both sides of the pipeline to prevent the medium from flowing out of or into the first single-phase storage component. When the second shut-off valve is closed, it forms a barrier on both sides of the pipeline to prevent the medium from flowing out of or into the two-phase storage component.

[0011] In the aforementioned erosion and wear testing device, the erosion module includes an inlet and an outlet. The inlet is connected to one end of a first single-phase storage component, a two-phase storage component, and a second single-phase storage component via connecting pipes. The outlet is connected to the other end of a two-phase storage component and a second single-phase storage component via connecting pipes, so that the second pipeline and the third pipeline respectively form circulation pipelines.

[0012] In the aforementioned erosion and wear testing device, the first single-phase storage component is a gas storage component, the two-phase storage component is a solid-liquid storage component, and the second single-phase storage component is a solid storage component. By opening or closing the shut-off valve, single-phase erosion and wear testing of solid or gas, or multi-phase erosion and wear testing of gas-solid, solid-liquid, gas-solid-liquid, or gas-solid-solid-liquid can be achieved.

[0013] The aforementioned erosion and wear testing device includes a first separator and a second separator. The first separator is disposed on the second single-phase storage component on the third pipeline near the outlet to separate the gas in the medium flowing through the first separator. The second separator is disposed on the second pipeline near the outlet to separate the gas in the medium flowing through the second separator, thereby realizing the recycling of the corresponding solid and / or solid-liquid mixture.

[0014] In the aforementioned erosion and wear testing device, the shut-off valve further includes a third shut-off valve disposed on the side of the first separator near the discharge port, and a fourth shut-off valve disposed on the side of the second separator near the discharge port. When the third shut-off valve is closed, it forms a barrier on both sides of the pipeline to prevent the medium from flowing into the first separator. When the fourth shut-off valve is closed, it forms a barrier on both sides of the pipeline to prevent the medium from flowing into the second separator.

[0015] In the aforementioned erosion and wear testing device, the first single-phase storage component includes an air compressor, a first flow valve, a first pressure gauge, and a first rotor flow meter arranged sequentially. The first pressure gauge and the first rotor flow meter are used to monitor the pressure and flow rate of the gas in the first pipeline, and control the opening of the first flow valve according to the monitored values ​​so that the medium in the air compressor flows to the erosion module. The first pressure gauge and the first rotor flow meter are also connected to the second single-phase storage component via a signal connection.

[0016] In the aforementioned erosion and wear testing device, the two-phase storage component includes a mixing tank, a water pump, a second flow valve, a second pressure gauge, and a second rotor flow meter arranged sequentially. The second pressure gauge and the second rotor flow meter monitor the pressure and flow rate of the gas in the second pipeline, and control the opening and closing of the mixing tank and the water pump, as well as the opening degree of the second flow valve, based on the monitoring data, so that the medium in the mixing tank flows to the erosion module. The second pressure gauge and the second rotor flow meter are also connected to the second single-phase storage component via a signal connection.

[0017] In the aforementioned erosion and wear testing device, the second single-phase storage component includes a receiver and a feeder. The receiver has an opening for receiving the medium and an outlet for outputting the medium. The feeder is connected to the receiver on the side opposite to the outlet so that the medium in the receiver flows to the erosion module. The feeder is also connected to the first single-phase storage component and the dual-phase storage component via signal connections.

[0018] The aforementioned erosion and wear testing device also includes a transparent tube and a monitoring system. The transparent tube is located near the feed inlet of the erosion module in the connecting pipe. The monitoring system includes a generator, a camera, and a computer acquisition system. The generator is located below the transparent tube and emits a laser onto the transparent tube. The camera is located on the opposite side of the transparent tube, takes pictures of the transparent tube, and feeds the information back to the computer acquisition system.

[0019] Compared with existing technologies, the advantages of this invention are as follows: By setting up a first single-phase storage component, a two-phase storage component, and a second single-phase storage component, and connecting these three components to the erosion module via connecting pipes, and further by setting shut-off valves at the corresponding connecting pipes, single-phase or multi-phase flow erosion wear testing can be achieved through the opening and closing of the shut-off valves. This effectively enriches the diversity of erosion wear testing, allowing users to selectively perform single-phase or multi-phase flow erosion wear tests as needed. Furthermore, the design of the shut-off valves prevents backflow of the medium from the first, second, or third pipeline to other pipelines, thereby effectively improving the stability of the test. It also simplifies the structure of the entire erosion wear testing device. In addition, the two-phase storage component contains a solid-liquid mixture. When used with the first single-phase storage component, it can achieve a gas-solid-liquid three-phase erosion wear test. When used with the first and second single-phase storage components, it can test a gas-solid-solid-liquid four-phase erosion wear test involving various solids, greatly satisfying the personalized testing needs of users.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figures 1 to 3 As shown, an erosion and wear testing device includes a first single-phase storage component 100, a two-phase storage component 200, a second single-phase storage component 300, an erosion module 400, a connecting pipe 500, a shut-off valve 600, a first separator 700, a second separator 710, and a monitoring system 800.

[0027] like Figures 1 to 3 As shown, an erosion wear testing apparatus includes:

[0028] The storage module includes a first single-phase storage component 100, a two-phase storage component 200, and a second single-phase storage component 300;

[0029] The erosion module 400 is connected to the first single-phase storage component 100, the two-phase storage component 200 and the second single-phase storage component 300 respectively via connecting pipes 500. A first pipeline 510 is formed between the erosion module 400, the connecting pipe 500 and the first single-phase storage component 100, a second pipeline 520 is formed between the erosion module 400, the connecting pipe 500 and the two-phase storage component 200, and a third pipeline 530 is formed between the erosion module 400, the connecting pipe 500 and the second single-phase storage component 300.

[0030] A shut-off valve 600 is disposed on a connecting pipe 500 for connecting or disconnecting the connecting pipe 500. It includes a first shut-off valve 610 disposed on a first pipe 510 and a second shut-off valve 620 disposed on a second pipe 520.

[0031] When any one or more of the first shut-off valve 610 and the second shut-off valve 620 are opened or closed, the corresponding first single-phase storage component 100 and two-phase storage component 200 are connected to or disconnected from the erosion module 400, respectively. This allows the medium in the first single-phase storage component 100, two-phase storage component 200, and second single-phase storage component 300 to flow to the erosion module 400 individually or simultaneously through the corresponding first pipeline 510, second pipeline 520, or third pipeline 530, thereby achieving single-phase or multi-phase flow erosion wear testing. This effectively enriches the diversity of erosion wear testing, allowing users to selectively perform single-phase or multi-phase flow erosion wear tests as needed. Furthermore, the design of the shut-off valve 600 prevents the medium on the first pipeline 510, second pipeline 520, or third pipeline 530 from flowing back to other pipelines, thus effectively improving the stability of the test. It also simplifies the structure of the entire erosion wear testing device.

[0032] Specifically, such as Figures 1 to 2 As shown, in this embodiment, the storage module includes a first single-phase storage component 100, a two-phase storage component 200, and a second single-phase storage component 300, which are respectively connected to the erosion module 400 via connecting pipes 500. The first single-phase storage component 100 is a gas storage component for storing gas, the two-phase storage component 200 is a solid-liquid storage component for storing solids and liquids, and the second single-phase storage component 300 is a solid storage component for storing solids. These components are used to store media such as gas, solids and liquids, and solids to meet the user's needs for testing erosion and wear of solids, gases, gas-solids, solids and liquids, gas-solids and liquids, and gas-solids and solids and liquids. Compared with the prior art, this greatly enriches the types of erosion and wear tests.

[0033] In this embodiment, the first single-phase storage component 100, the second single-phase storage component 300, and the two-phase storage component 200 are all disposed on the left side of the erosion module 400 and connected to the erosion module 400 via a connecting pipe 500. A first pipeline 510 is formed between the first single-phase storage component 100, the connecting pipe 500, and the erosion module 400; a second pipeline 520 is formed between the two-phase storage component 200, the connecting pipe 500, and the erosion module 400; and a third pipeline 530 is formed between the second single-phase storage component 300, the connecting pipe 500, and the erosion module 400. This allows the media in the first single-phase storage component 100, the second single-phase storage component 300, and the two-phase storage component 200 to flow into the erosion module 400.

[0034] To achieve the recycling and circulation of solids and solid-liquid mixtures, in this embodiment, one end of the second single-phase storage component 300 and the two-phase storage component 200 are connected to the inlet 410 of the erosion module 400 via a connecting pipe 500, and the other end is connected to the storage port of the erosion module 400 via a connecting pipe 500. This allows the solid or solid-liquid medium entering the erosion module 400 to flow back to the second single-phase storage component 300 or the two-phase storage component 200 through the outlet 420 of the erosion module 400. On the one hand, this saves the storage structure required for medium discharge, effectively simplifying the overall structure of the device. On the other hand, it achieves the recycling and circulation of the medium, thereby effectively improving the economy and continuity of the experiment and avoiding the waste of the medium.

[0035] To expel the gas entering the pipeline during multiphase flow testing and separate it from the solid or solid-liquid mixture, ensuring the purity of the solid or solid-liquid medium, this embodiment also includes a first separator 700 and a second separator 710. The first separator 700 is a cyclone separator, located on the third pipeline 530 near the outlet 420 of the second single-phase storage component 300, to separate the gas flowing through the first separator 700, so that the medium returning to the second single-phase storage component 300 is solid. The second separator 710 is a gas-liquid separator, located on the second pipeline 520 near the outlet 420 of the two-phase storage component 200, to separate the gas flowing through the second separator 710, so that the medium returning to the two-phase storage component 200 is solid-liquid, thereby achieving the recycling and flow of the corresponding solid and / or solid-liquid mixtures.

[0036] In this embodiment, the first single-phase storage component 100 includes an air compressor 110, a first flow valve 120, a first pressure gauge 130, and a first rotor flow meter 140, arranged sequentially from left to right and connected by a connecting pipe 500. The first rotor flow meter 140 is connected to a first shut-off valve 610 on the side opposite to the first pressure gauge 130 via the connecting pipe 500. The air compressor 110 is used to provide gas, and the first pressure gauge 130 and the first rotor flow meter 140 are used to monitor the pressure and flow rate of the gas in the first pipeline 510. Based on the monitored values, the opening degree of the first flow valve 120 is controlled, thereby realizing real-time adjustment of the flow rate of the medium flowing from the air compressor 110 to the erosion module 400, and realizing intelligent control of the erosion wear test.

[0037] In this embodiment, the dual-phase storage component 200 includes, from left to right, a mixing tank 210, a water pump 220, a second flow valve 230, a second pressure gauge 240, and a second rotor flow meter 250, which are connected by a connecting pipe 500. The side of the second rotor flow meter 250 facing away from the second pressure gauge 240 is connected to the second shut-off valve 620 through the connecting pipe 500. The mixing tank 210 has a stirring function and contains solids and liquids. The water pump 220 provides output power for the medium in the mixing tank. The second pressure gauge 240 and the second rotor flow meter 250 monitor the pressure and flow rate of the gas in the second pipeline 520, and control the opening and closing of the mixing tank 210 and the water pump 220, as well as the opening degree of the second flow valve 230, based on the monitoring data. This achieves stirring of the medium in the mixing tank 210 and real-time adjustment of the flow rate of the medium flowing from the water pump 220 to the erosion module 400, realizing intelligent control of the erosion wear test.

[0038] In this embodiment, the mixing tank 210 is connected to the second separator 710 on the side away from the water pump 220 to receive the solid-liquid mixture after the gas phase is discharged from the second separator 710, so as to realize the recycling and flow of the solid-liquid mixture.

[0039] In this embodiment, the solid is sand and the liquid is water.

[0040] In this embodiment, the second single-phase storage component 300 includes a receiver 310 and a feeder 320 arranged from top to bottom and connected by a connecting pipe 500. The feeder 320 is connected to the inlet 410 of the erosion module 400 via the connecting pipe 500. The receiver 310 is hopper-shaped and has an opening 311 for receiving the medium and an outlet 312 for outputting the medium. The opening 311 of the receiver 310 is connected to the first separator 700 to receive the solid after the gas phase is discharged from the first separator 700, so as to realize the recycling and flow of the solid. One side of the feeder 320 is connected to the side of the receiver 310 opposite to the outlet 311, and the other side is connected to the inlet 410 of the erosion module 400 via the connecting pipe 500, so that the medium in the receiver 310 flows to the erosion module 400 for solid phase erosion test.

[0041] It is worth noting that, due to the structure of the opening 311 of the receiving machine, the flow rate of sand entering the feeder 320 can be manually controlled in real time, thereby realizing intelligent control of the erosion and wear test.

[0042] In this embodiment, the receiving medium is solid sand particles.

[0043] To achieve linkage with the first single-phase storage component 100, the dual-phase storage component 200, and the second single-phase storage component 300, in this embodiment, the feeder 320 forms signal connections with the first pressure gauge 130 and the first rotor flowmeter 140 of the first single-phase storage component 100, and the second pressure gauge 240 and the second rotor flowmeter 250 of the dual-phase storage component 200. When the first pressure gauge 130 and the first rotor flowmeter 140 or the second pressure gauge 240 and the second rotor flowmeter 250 reach a preset value, the feeder 320 starts, thereby achieving linkage with the first single-phase storage component 100 and the dual-phase storage component 200.

[0044] like Figure 2 , Figure 3 As shown, in this embodiment, the erosion module 400 is rectangular and has a 90° bent tube-shaped mounting part 430 inside. The mounting part 430 is coated with glue so that the erosion material 440 is tightly attached to the mounting part 430. The two ends of the erosion material 440 are fixedly connected by bolts and nuts (not shown in the figure), so that the medium flowing into the erosion module 400 flows along the length of the erosion material 440, thereby realizing the erosion and wear test of the erosion material 440.

[0045] In this embodiment, the erosion module 400 includes an inlet 410 and an outlet 420. The inlet 410 is connected via a connecting pipe 500 to a first shut-off valve 610 connected to the first single-phase storage component 100, a second shut-off valve 620 connected to the two-phase storage component 200, and a feeder 320 connected to the two-phase storage component 200. The outlet 420 is connected via a connecting pipe 500 to a third shut-off valve 630 connected to the second single-phase storage component 300, and a fourth shut-off valve 640 connected to the two-phase storage component 200, so that the second pipe 520 and the third pipe 530 form circulation pipes respectively, realizing the closed-loop circulation flow and use.

[0046] To prevent backflow of the medium due to air, in this embodiment, the connecting pipe 500 includes a tee connector 540 for connecting the various pipes. The tee connector 540 is an R-type tee connector, which is respectively located below the feeder 320, on the side of the first shut-off valve 610 and the second shut-off valve 620 near the inlet 410 of the erosion module 400, and on the side of the third shut-off valve 630 and the fourth shut-off valve 640 near the outlet 420 of the erosion module 400, so as to guide the medium in the connecting pipe 500, effectively prevent backflow of the medium, and improve the stability of the erosion test.

[0047] To further improve the stability of the erosion test, the coordination of single-phase or multi-phase flow erosion tests, and the ease of operation, a shut-off valve 600 is also provided in this embodiment. This shut-off valve 600 is installed on the connecting pipe 500 to open or close the connecting pipe 500. It includes a first shut-off valve 610 installed on the first pipeline 510 near the inlet 410 of the first storage component, a second shut-off valve 620 installed on the second pipeline 520 near the inlet 410 of the two-phase storage component, a third shut-off valve 630 installed on the third pipeline 530 near the outlet 420 of the first separator 700, and a fourth shut-off valve 640 installed on the second pipeline 520 near the outlet 420 of the second separator 710.

[0048] Specifically, when the first shut-off valve 610 is closed, it forms a barrier on both sides of the first shut-off valve 610 to prevent the medium from flowing out of or into the first single-phase storage component 100; when the second shut-off valve 620 is closed, it forms a barrier on both sides of the second shut-off valve 620 to prevent the medium from flowing out of or into the dual-phase storage component 200; when the third shut-off valve 630 is closed, it forms a barrier on both sides of the third shut-off valve 630 to prevent the medium from flowing into the first separator 700; and when the fourth shut-off valve 640 is closed, it forms a barrier on both sides of the fourth shut-off valve 640 to prevent the medium from flowing into the second separator 710.

[0049] On the one hand, the first shut-off valve 610 can be used as a valve switch to control the outflow of medium from the first single-phase storage component 100, and the second shut-off valve 600 can be used as a valve switch to control the outflow of medium from the two-phase storage component 200. Through the cooperation between the shut-off valves 600, different types of erosion wear tests can be achieved, effectively enriching the types of erosion wear tests. On the other hand, when the first shut-off valve 610 is closed, it can also prevent the medium from flowing back into the first single-phase storage component 100 from other pipelines. When the second shut-off valve 620 is closed, it can also prevent the medium from flowing back into the two-phase storage component 200 from other pipelines. When the third shut-off valve 630 is closed, it can prevent the medium circulating in other pipelines from flowing back into the first separator 700 from other pipelines. When the fourth shut-off valve 640 is closed, it can prevent the medium circulating in other pipelines from flowing back into the second separator 710 from other pipelines. This effectively ensures the independence between each pipeline and improves the stability of the erosion wear test operation.

[0050] Furthermore, compared with existing technologies, the installation of the shut-off valve 600 makes the entire erosion and wear test device more compact and simple, greatly reducing manufacturing costs.

[0051] To achieve real-time monitoring and data recording of the erosion and wear test, this embodiment also includes a transparent tube 550 and a monitoring system 800. The transparent tube 550 is located near the feed inlet 410 of the connecting tube 500 close to the erosion module 400, so that the user can directly observe the erosion state and use the monitoring system 800 to input and analyze data. The monitoring system 800 includes a generator 810, a camera 820, and a computer acquisition system 830. The generator 810 is a high-frequency laser generator, located below the transparent tube 550, and emits a laser beam onto the transparent tube 550 to allow the camera 820 to capture a clear image. The camera 820 is a CCD camera, located on the opposite side of the transparent tube 550, to take pictures of the transparent tube 550, and feeds the information after taking the pictures back to the computer acquisition system 830 through a synchronizer 840 for the user to observe and analyze the data.

[0052] The erosion wear testing apparatus provided in this embodiment can perform erosion wear tests of the following types: single-phase flow erosion wear test and multiphase flow erosion wear test. The single-phase flow erosion wear test includes solid phase erosion wear test and gas phase erosion wear test; the multiphase flow erosion wear test includes gas-solid two-phase erosion wear test, solid-liquid two-phase erosion wear test, gas-solid-liquid three-phase erosion wear test, and gas-solid-solid-liquid four-phase erosion wear test. The test operation method is as follows.

[0053] In this embodiment, during the solid-phase erosion wear test, the first shut-off valve 610, the second shut-off valve 620, and the fourth shut-off valve 640 are closed, while the third shut-off valve 630 is open. The user manually places sand particles in the receiving device 310 and manually starts the feeder 320, allowing the sand particles to flow through the transparent tube 550 into the erosion module 400 and circulate along the third pipeline 530. Simultaneously, the monitoring system 800 records and analyzes data through the transparent tube 550 to achieve the solid-phase erosion wear test. When the sand particles flow out of the erosion module 400, they flow back into the feeder 320 sequentially through the third shut-off valve 630, the first separator 700, and the receiving device 310, allowing the feeder 320 to continue operating for the user to conduct cyclic tests.

[0054] In this embodiment, during the vapor phase erosion wear test, the first shut-off valve 610 and the third shut-off valve 630 are open, while the second shut-off valve 620 and the fourth shut-off valve 640 are closed. The first pressure gauge 130 and the first flow meter monitor the pressure and flow rate of the gas in the first pipeline 510. When the gas pressure in the first pipeline 510 reaches a predetermined value, the first flow valve 120 is opened, and its opening is adjusted in real time according to the monitoring data. The gas in the air compressor 110 flows through the transparent tube 550 to the erosion module 400 via the first shut-off valve 610. Simultaneously, the monitoring system 800 records and analyzes data through the transparent tube 550 to realize the vapor phase erosion wear test. When the gas flows out of the erosion module 400, it passes through the third shut-off valve 630 and the first separator 700 in sequence. Since the air compressor 110 can directly convert air, it does not need to set up a separate circulation loop. The air compressor 110 can achieve continuous gas output for users to conduct circulation tests.

[0055] In this embodiment, during the gas-solid two-phase erosion wear test, the first shut-off valve 610 and the third shut-off valve 630 are open, while the second shut-off valve 620 and the fourth shut-off valve 640 are closed. The first pressure gauge 130 and the first flow meter monitor the pressure and flow rate of the gas in the first pipeline 510. When the gas pressure in the first pipeline 510 reaches a predetermined value, the first flow valve 120 is opened, and a signal is sent to the feeder 320 to open it, allowing the gas and solid to flow simultaneously through the transparent tube 550 to the erosion module 40. Within the erosion module 400, the solids circulate along the third pipeline 530, while the monitoring system 800 records and analyzes data through the transparent pipe 550 to achieve a gas-solid two-phase erosion wear test. When the gas flows out of the erosion module 400, it flows through the third shut-off valve 630 to the first separator 700 and is discharged. When the solids flow out of the erosion module 400, they flow through the third shut-off valve 630 to the first separator 700, and then flow through the first separator 700 to the receiving device 310 and the feeder 320 in sequence, realizing the circulation and recycling of the solids.

[0056] In this embodiment, during the solid-liquid two-phase erosion wear test, the second shut-off valve 620 and the fourth shut-off valve 640 are opened, while the first shut-off valve 610 and the third shut-off valve 630 are closed. The second pressure gauge 240 and the second flow meter monitor the pressure and flow rate of the gas in the second pipeline 520. When the gas pressure in the second pipeline 520 reaches a predetermined value, the mixing tank 210 is started, thereby mixing and stirring the liquid and solid within it. Then, the water pump 220 and the second flow valve 230 are switched on and off, thereby mixing... The solid and liquid phases flow through the second shut-off valve 620 and the transparent tube 550 into the erosion module 400, and circulate along the second pipeline 520. At the same time, the monitoring system 800 records and analyzes data through the transparent tube 550 to realize the solid-liquid two-phase erosion wear test. When the liquid and solid phases flow out of the erosion module 400, they flow through the fourth shut-off valve 640 to the second separator 710, and then flow through the second separator 710 to the mixing tank 210 and the water pump 220 in sequence, realizing the circulation and recycling of the solid and liquid phases.

[0057] In this embodiment, during the gas-solid-liquid three-phase erosion wear test, the first shut-off valve 610, the second shut-off valve 620, and the fourth shut-off valve 640 are opened, the third shut-off valve 630 is closed, and the feeder 320 is manually closed. The first pressure gauge 130 and the first flow meter monitor the pressure and flow rate of the gas in the first pipeline 510. When the gas pressure in the first pipeline 510 reaches a predetermined value, the first flow valve 120 is opened, and the opening of the first flow valve 120 is adjusted in real time according to the monitoring data. The gas in the air compressor 110 flows through the transparent pipe 550 to the erosion module 400 via the first shut-off valve 610. Simultaneously, the second... Pressure gauge 240 and second flow meter monitor the pressure and flow rate of the gas in the second pipeline 520. When the gas pressure in the second pipeline 520 reaches a predetermined value, the mixing tank 210 is started to mix and stir the liquid and solid inside. Then, the water pump 220 and the second flow valve 230 are switched on and off, so that the mixed solid and liquid flow through the second shut-off valve 620, through the transparent tube 550 into the erosion module 400, and circulate along the second pipeline 520. At the same time, the monitoring system 800 records and analyzes data through the transparent tube 550 to realize the gas-solid-liquid three-phase erosion wear test. The circulation of solid and liquid has been disclosed above and will not be repeated here.

[0058] In this embodiment, during the four-phase erosion wear test of gas-solid-solid-liquid, the first shut-off valve 610, the second shut-off valve 620, and the fourth shut-off valve 640 are opened, while the third shut-off valve 630 is closed. The feeder 320 is manually opened first, and after the first round of solids flows out, it is manually closed again, so that there can be two kinds of solids in the erosion module 400, and both kinds of solids circulate along the second pipeline 520, thereby realizing the four-phase erosion wear test of gas-solid-solid-liquid. The circulation principle of gas and solid-liquid is the same as described above, and will not be repeated here.
