Description

Technical Field

[0001] This invention belongs to the field of erosion wear, specifically relating to an intelligent solid-liquid two-phase flow erosion wear test device and method. Background Technology

[0002] Erosion wear refers to the phenomenon where solid particles carried by a fluid impact the surface of a material, causing damage. Erosion wear is prevalent in industries such as petroleum and chemical engineering, and is a significant cause of failure in critical components and equipment. In oil extraction using submersible electric pump units (SPMP), severe erosion wear at the gas-liquid separator inlet often leads to breakage, causing the pump unit to fall into the well and resulting in substantial economic losses. To further investigate the relationship between materials and erosion wear, and to explore materials with better erosion resistance, it is necessary to develop an intelligent erosion testing device capable of operating under multiple conditions.

[0003] Most current erosion wear testing equipment only provides a single erosion test and lacks the ability to actively collect data. Data such as flow rate and sample weight before and after erosion must be obtained manually. Furthermore, when facing multi-condition erosion tests, the experimenter needs to reinstall the sample and adjust the flow rate and impact angle. The manual operations required by the experimenter are cumbersome and prone to significant errors. To address these issues, this invention proposes an improvement. Summary of the Invention

[0004] This invention proposes an intelligent solid-liquid two-phase flow erosion and wear testing device and method. The device combines a PLC with traditional mechanical testing equipment, using the PLC to achieve electronic signal transmission between the testing devices. This intelligently completes the entire erosion test process, significantly reducing manual operations required by the experimenter under various conditions and improving testing efficiency and accuracy. The device actively collects test data through a flow meter, weighing device, temperature control device, and control console. At the end of the test, it actively outputs the erosion rate of the sample under different conditions. This device can accurately simulate the erosion and wear failure of materials under multiple conditions and has advantages such as easy and precise control of impact angle and erosion rate. It solves the aforementioned problems existing in the use of prior art.

[0007] Preferably, the sample fixture of the present invention includes a fixture base, an L-shaped metal clamping plate, a cover, a clamping element, an electromagnet, a fixture body, a transmission gear, a transmission motor, a hydraulic rod, a motor, a pressure sensor, and a control unit; the fixture base is connected to the fixture body via the cover and bolts; the L-shaped metal clamping plate is connected to the motor via a threaded rod; the upper part of the clamping element is fixed in a groove in the fixture body, and the clamping element is connected to the electromagnet via a spring, with an embedded magnet at the end of the clamping element near the electromagnet; the electromagnet is fixed to the left end of the upper groove of the fixture body; the transmission gear is connected to the transmission motor via a transmission shaft. The motor is connected, and the transmission gears are located at the left and right ends of the fixture body and mesh with the gears at the left and right ends of the fixture base; the transmission motor 34 is fixed to the fixture body by bolts; the hydraulic rod has bolt holes at both the upper and lower ends, the lower end of the hydraulic rod is connected to the lower end of the fixture body by bolts, and the upper end of the hydraulic rod is connected to the lower end of the fixture base by bolts; the motor 36 is fixed to the upper end of the fixture base by bolts; the pressure sensor is located at the center of the fixture base where the sample is clamped; the control unit is located on the side wall of the fixture body, connected to the control console through a PLC control system, and the control unit is connected to all motors on the fixture.

[0008] Preferably, the fixture base of the present invention is provided with a push rod inside; the push rod has gear racks on the left and right sides that mesh with transmission gears; the transmission gears are connected to a motor through a transmission shaft; the motor is fixed to the bottom of the fixture base by bolts; the gear on the right side of the fixture base has a protruding small gear, the small gear is coaxial with the gear, the small gear is half the size of the gear, and the small gear can cooperate with the gear groove on the left side of the clamping element.

[0009] Preferably, the sample transportation and data acquisition module of the present invention includes a drying and cleaning device, a weighing device, a control unit, a lifting and storage device, a transportation device, a lifting platform, and a control console; the weighing device is divided into two parts, one for weighing the sample before the erosion test and connected to the transportation device and the lifting platform, and the other for weighing the sample after the erosion test and connected to the drying and cleaning device and the lifting and storage device; the control console is connected to a flow meter, a throttle valve, a motor, a temperature regulator, a robotic arm, the weighing device, and a clamp via electronic signals.

[0010] A method for conducting erosion wear tests using the above-described apparatus includes the following steps: Step (1): According to the test requirements, set the impact angle, erosion speed and temperature through the control console, and place the surface polished block sample with a size of 30mm*30mm*5mm on the lifting platform. Push the sample to the weighing device through the control unit. After the sample stays at the weighing device for 5 seconds, the weight measurement before the erosion test is completed. Step (2): The weighing device pushes the sample onto the moving slider of the transport device via the push rod. The moving slider transports the sample to the other end of the transport device. Then the push rod pushes the sample onto the fixture base. The pressure sensor on the fixture base senses the pressure, and the motor drives the L-shaped metal clamp to clamp the sample, thus completing the clamping of the sample. The fixture begins to adjust the angle according to the impact angle preset on the control panel. Step (3): The control console transmits the preset test temperature to the temperature regulator via an electronic signal. The heating unit heats the storage tank. The temperature sensor stops heating after detecting that the temperature of the erosion medium has reached the test temperature. When the temperature of the erosion medium is lower than the test temperature, the heating unit reheats the storage tank to maintain the temperature of the erosion medium. The stirring motor is started to drive the blades to stir the erosion medium, keeping the erosion medium uniform and avoiding sand deposition. Step (4): Start the motor through the control console. The motor provides kinetic energy to the mud pump. The mud pump extracts the erosion medium from the storage tank. The erosion medium flows through the pipeline, passing through the T-shaped tee, the throttle valve, and the flow meter, and finally flows out through the nozzle. The flow meter feeds back the flow rate in the pipeline to the control console in the form of an electronic signal. The control console sets the test flow rate according to the test requirements and transmits the electronic signal to the throttle valve. The throttle valve adjusts the opening and closing of the valve, thus completing the control of the flow rate in the pipeline. Step (5): Wait 10 minutes. When the flow rate in the pipeline is stable, the robotic arm 1 rotates itself to move the clamp for holding the sample to the direct below the nozzle. At the same time, the timing module of the control console starts to start timing automatically. After the erosion medium impacts the block sample, it will flow into the pipeline along the wall of the spray chamber and finally flow back into the storage tank, thus completing one cycle of the erosion medium. Step (6): When the erosion wear test time reaches the preset time, the motor, stirring motor and heating unit stop working, and the throttle valve is completely closed, and the nozzle no longer sprays erosion medium; at this time, the robotic arm will rotate itself again, align the clamp with the air-drying and cleaning device, and the push rod on the clamp will push the block sample onto the loading tray of the air-drying and cleaning device. The loading tray is recycled, and after the air-drying and cleaning device cleans the erosion medium remaining on the surface of the block sample, it is sent to the weighing device by the push rod. After waiting for 5 seconds to complete the weighing, the push rod of the weighing device will send the block sample to the vertical lifting storage device for storage, thus completing a complete solid-liquid two-phase erosion wear test. The erosion rate is equal to the weight before erosion minus the weight after erosion and then divided by the erosion time. Step (7): After completing one erosion test, the control panel will display the erosion rate of the output sample at the preset impact angle, erosion speed and temperature. If multiple samples need to be tested, a cycle can be set on the control panel. In the cycle state, the solid-liquid two-phase flow erosion wear test device will repeat the work according to steps 1-6 until the last cycle ends and the power is completely turned off.

[0011] In summary, the beneficial effects of the present invention are as follows: (1) The intelligent solid-liquid two-phase flow erosion and wear test device of the present invention uses the erosion medium formed by the mixture of water and sand to conduct erosion and wear tests on the sample. The erosion medium is recycled in the test device, which can effectively reduce resource waste. For samples of different thicknesses, the device does not need to change the clamp according to the thickness of the sample. It only needs to modify the thickness of the sample in the PLC control system of the control console to enable the clamp to clamp samples of different thicknesses. The thickness range of the sample is 5mm to 30mm. The device realizes the automatic transportation and storage function of the sample by controlling the lifting platform, the transportation device and the lifting storage device through PLC.

[0012] (2) The motors on the fixture of the present invention are all connected to the PLC control system of the console. By presetting the impact angle of the test on the console, the electronic signal is emitted to drive the motor to drive the gear to rotate a certain angle, thereby completing the precise adjustment of the impact angle. When dealing with the impact angle requirements of multiple sets of different samples, it is only necessary to set the corresponding angles one by one on the console. After the erosion test at the corresponding angle is completed, the fixture will automatically adjust in sequence according to the set angle. The PLC control system can help the angle adjustment of the fixture to be more convenient and accurate.

[0013] (3) The control console of the present invention is connected to the flow meter, throttle valve, temperature regulator and weighing device through the PLC control system. The flow meter will provide real-time feedback of the flow information in the pipeline. The weighing device will provide feedback of the sample weight information before and after the test. After a test, the control console will automatically calculate the erosion rate of the sample under the working condition based on the flow rate of the erosion medium, the change in the weight of the sample, the impact angle of the sample, the test time and temperature and save the test parameters. The function of automatically collecting test data greatly improves the efficiency of the entire erosion test.

[0014] (4) The flow regulation of the present invention is achieved by a flow meter, a throttle valve and a control console. The flow meter feeds back the real-time flow in the pipeline to the control console in the form of an electronic signal. The control program of the control console compares the flow with the preset test flow and sends a corresponding signal to the throttle valve according to the comparison result. The throttle valve’s built-in motor drives the valve to open and close, thereby achieving precise flow regulation. The intelligent flow regulation avoids errors caused by human operation and improves the accuracy of flow regulation. Attached Figure Description

Step (2): The weighing device (20) pushes the sample (3) onto the transport device (23), the transport device (23) transports the sample (3) onto the fixture base (27), the pressure sensor (37) senses the pressure, the motor (36) drives the L-shaped metal clamp (28) to clamp the sample (3), and the fixture (2) adjusts the angle according to the impact angle preset on the control panel (26). Step (3): The control console (26) transmits the preset test temperature to the temperature regulator (15), the heating unit (17) heats the storage tank, the temperature sensor (14) detects the temperature of the erosion medium, and stops heating after the test temperature is reached. The stirring motor (12) is started to drive the blades (18) to stir the erosion medium. Step (4): Start the motor (11) via the control console (26). The motor (11) drives the mud pump (9) to extract the erosion medium from the storage tank (13). The erosion medium flows through the T-shaped tee (8), the throttle valve (6) and the flow meter (7), and finally flows out through the nozzle (4). The flow meter (7) feeds back the flow signal to the control console (26), and the control console (26) controls the throttle valve (6) to adjust the flow. Step (5): After the flow rate in the pipeline stabilizes, the robotic arm (1) moves the clamp (2) directly below the nozzle (4), and the control console (26) starts timing; the erosion medium impacts the block sample (3) and then flows back to the storage tank (13) along the spray chamber (5). Step (6): When the erosion and wear test time reaches the preset time, the motor (11), stirring motor (12) and heating unit (17) stop working and the throttle valve (6) is closed; the robotic arm (1) aligns the clamp (2) with the air-drying and cleaning device (19), the push rod (39) pushes the block sample (3) to the air-drying and cleaning device (19) for cleaning, and then sends it to the weighing device (20) for erosion and weighing, and finally sends the sample to the lifting storage device (21) for storage. Step (7): The console (26) displays the erosion rate of the output sample under the preset working conditions; if there are multiple samples, set the cycle and repeat steps 1-6.

5. The method according to claim 4, characterized in that, The size of the block sample (3) is 30mm×30mm×5mm, and the surface is polished; the erosion rate is equal to the weight before erosion minus the weight after erosion and then divided by the erosion time.
