Description
Technical Field
[0001] The utility model relates to the technical field of aircraft engine testing, in particular to a sand swallowing tester. Background Art
[0002] The aircraft engine sand swallowing test is one of the common experiments to test the performance and reliability of aircraft engines. This test is usually carried out on the ground to simulate various conditions that the engine may encounter in actual operation.
[0003] In a sand ingestion test, an engine is injected with a defined amount of fine particles (usually sand or dust) and then run at normal operating speed for a period of time. By observing and analyzing the engine's performance, its resistance to particle ingress and its susceptibility to particle damage or clogging can be assessed.
[0004] This test can help engineers better understand the durability and reliability of the engine, optimize the design and improve the performance of related systems and filters to ensure that the engine works effectively in the real operating environment. This is critical to aircraft safety and performance. At present, there is no dedicated sand blasting device when conducting sand swallowing tests, and it is not easy to control the humidity of the sand during sand blasting, so the test results are not ideal. Utility Model Content
[0005] The utility model provides a sand swallowing tester, which solves the above-mentioned technical problems.
[0006] The utility model solves the above-mentioned technical problems as follows:
[0007] A sand swallowing tester comprises a lower hopper, a culvert, a bracket and a retaining frame, wherein one end of the culvert is provided with an air nozzle through the retaining frame, the bottom end of the culvert is provided with a bracket, the culvert is erected on a plane through the bracket, the upper surface of the culvert is provided with a sand inlet, the opening of the sand inlet is provided with a funnel-shaped guide groove, the culvert is provided with a lower hopper through the sand inlet, and the lower surface of the culvert is provided with a liquid inlet.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.
[0009] Furthermore, the interior of the culvert is connected to a water pump and a water source through a liquid inlet.
[0010] The beneficial effects of adopting the above further scheme are:
[0011] By connecting to the water pump and water source, water can be easily introduced into the culvert. This ensures that there is enough water supply during the test, and there is no need to frequently stop the test to add water. This improves the efficiency of the test and is particularly important in large-scale tests where the supply of large amounts of water may be difficult. Water is an important component of the mixed flow of sand and water. By connecting to the water pump and water source, the water supply can be flexibly controlled during the test to simulate the mixed flow of water and sand in actual engineering. This helps to more accurately study and analyze the behavior of the mixed flow of water and sand, and provide a reference for engineering design and practical applications. The flow rate and pressure of the water can be adjusted by controlling the water pump. This allows the water input to be flexibly adjusted as needed during the test to adapt to different test conditions and research needs. Adjustable water flow and pressure are very important for simulating different flow patterns, exploring water flow characteristics, and evaluating engineering performance.
[0012] Furthermore, the lower hopper is filled with sand, and the sand in the lower hopper enters the culvert through the sand inlet and is blown out by the compressed air ejected from the air nozzle.
[0013] The beneficial effects of adopting the above further scheme are:
[0014] The lower hopper can be used to fill sand to ensure that there is enough sand supply during the test. This ensures the continuity and consistency of the test, and there is no need to stop the test frequently to add sand, which improves the efficiency of the test. The sand is introduced into the culvert through the sand inlet, and the flow of sand can be accurately controlled. In this way, the input amount of sand can be adjusted as needed during the test to adapt to different test conditions and research needs, which improves the flexibility and controllability of the test. The compressed air ejected by the air nozzle can blow the sand out of the culvert to achieve the movement and flow of sand in the test. The existence of the air nozzle can simulate the air flow in the actual project, which is closer to the water-sand mixed flow in the real environment. The role of the air nozzle can also achieve uniform distribution of sand. The compressed air is ejected upward from the bottom of the culvert through the air nozzle, which can make the sand fully suspended in the air, thereby achieving uniform distribution of sand. This helps to simulate the water-sand mixed flow in the actual project and improve the reliability and authenticity of the test.
[0015] Furthermore, the air nozzle is connected to a compressed air source through an air pipe.
[0016] The beneficial effects of adopting the above further scheme are:
[0017] By connecting the air pipe to the compressed air source, the air supply can be obtained stably. This ensures that the air nozzle can continuously provide compressed air during the test, without worrying about insufficient or interrupted air supply, thereby improving the continuity and stability of the test. After connecting the compressed air source, the pressure and flow of the compressed air ejected from the air nozzle can be flexibly controlled by adjusting the air pressure at the air source end. This allows the air pressure to be adjusted as needed during the test to adapt to different test conditions and research needs, improving the flexibility and controllability of the test. Using a compressed air source as the air source supply for the air nozzle may be more energy-saving than other air source methods. Compressed air sources usually have a high compression efficiency and can provide sufficient compressed air without wasting energy, which helps to reduce test costs and is environmentally friendly. Connecting the air pipe to the compressed air source is easy to install and relatively simple during daily use and maintenance. This makes the operation of the air nozzle more convenient and reliable.
[0018] Furthermore, a gap is left between the retaining frame and the culvert to facilitate the replenishment of external air into the culvert, thereby increasing the gas flow in the culvert.
[0019] The beneficial effects of adopting the above further scheme are:
[0020] The gap between the holder and the culvert allows the outside air to flow freely into the culvert. This can increase the gas flow in the culvert and improve the flow performance. By increasing the gas flow, the flow conditions in the actual project can be better simulated, making the test results more accurate and reliable. After the outside air flows into the culvert, it can mix with the gas in the culvert. This helps to improve the uniform distribution and mixing of the gas, thereby improving the gas balance and stability during the test. The gap between the holder and the culvert can promote ventilation. The supplement of external air can effectively eliminate or reduce the accumulation and accumulation of gas in the culvert, maintain good air quality and environmental conditions, and provide a gas environment more suitable for the test needs. Through the gap between the holder and the culvert, the supplement of external air can reduce or avoid deviations and errors caused by the restricted gas flow in the culvert. This helps to improve the accuracy and repeatability of the test results.
[0021] The beneficial effects of the utility model are:
[0022] The tester consists of a lower hopper, a culvert, a bracket and a retaining frame, and has a relatively simple structure and is easy to manufacture and install, which makes the maintenance and operation of the tester more convenient.
[0023] The compressed air flow rate can be controlled by connecting the air nozzle and the air pipe to the compressed air source. This can adjust the gas flow rate and pressure in the culvert to control the swallowed sand. The external air is added into the culvert to increase the gas flow rate, thereby improving the reliability and accuracy of the test.
[0024] The sand is loaded into the culvert through the lower hopper and sand inlet, which can achieve a stable supply of sand. The funnel-shaped guide groove can guide the sand to the air nozzle, ensuring that the sand enters the culvert and is blown out by the air nozzle. This ensures that the sand is evenly distributed and consistent during the test.
[0025] The culvert is connected to the water pump and water source through the liquid inlet, which can easily provide water. In this way, water can be added during the test to simulate the water-sand mixed flow in actual conditions, which is closer to the actual engineering environment.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] See also Figures 1 to 5 As shown, the embodiments provided by the utility model:
[0038] Embodiment 1
[0039] A sand swallowing tester includes a lower hopper 1, a culvert 2, a bracket 4 and a retaining frame 6. An air nozzle 5 is installed at one end of the culvert 2 through the retaining frame 6. The air nozzle 5 is connected to a compressed air source through an air pipe. The air source supply can be stably obtained through the air pipe. This ensures that the air nozzle 5 can continuously provide compressed air during the test, and there is no need to worry about insufficient or interrupted air source, thereby improving the continuity and stability of the test. After connecting the compressed air source, the pressure and flow of the compressed air ejected by the air nozzle 5 can be flexibly controlled by adjusting the air pressure at the air source end. This allows the air pressure to be adjusted as needed during the test to adapt to different test conditions and research needs, thereby improving the flexibility and controllability of the test. Using a compressed air source as the air source supply for the air nozzle 5 may save more energy than other air source methods. A compressed air source usually has a high compression efficiency and can provide sufficient compressed air without wasting energy, which helps to reduce the cost of the test and is environmentally friendly. Connecting the air pipe to the compressed air source is easy to install and is relatively simple during daily use and maintenance. This makes the operation of the air nozzle 5 more convenient and reliable. There is a gap between the retainer 6 and the culvert 2, which is convenient for external air to be supplemented into the culvert 2, thereby increasing the gas flow in the culvert 2. The gap between the retainer 6 and the culvert 2 allows external air to flow freely into the culvert 2. In this way, the gas flow in the culvert 2 can be increased and the flow performance can be improved. By increasing the gas flow, the flow conditions in the actual project can be better simulated, making the test results more accurate and reliable. After the external air flows into the culvert 2, it can be mixed with the gas in the culvert 2. This helps to improve the uniform distribution and mixing degree of the gas, thereby improving the gas balance and stability during the test. The gap between the retainer 6 and the culvert 2 can promote the ventilation effect. The supplement of external air can effectively eliminate or reduce the accumulation and accumulation of gas in the culvert 2, maintain good air quality and environmental conditions, and provide a gas environment more suitable for the test requirements. Through the gap between the retainer 6 and the culvert 2, the supplement of external air can reduce or avoid the deviation and error caused by the restricted gas flow in the culvert 2. This helps to improve the accuracy and repeatability of the test results. A bracket 4 is provided at the bottom end of the culvert 2 , and the culvert 2 is erected on a plane through the bracket 4 .
[0040] The upper surface of the culvert 2 is provided with a sand inlet 7, and a funnel-shaped guide groove 8 is provided at the opening of the sand inlet 7. The culvert 2 is provided with a lower hopper 1 through the sand inlet 7. The lower hopper 1 is filled with sand, and the sand in the lower hopper 1 enters the interior of the culvert 2 through the sand inlet 7 and is blown out by the compressed air ejected by the air nozzle 5. The lower hopper 1 can be used to fill sand to ensure that there is enough sand supply during the test. In this way, the continuity and consistency of the test can be guaranteed, and there is no need to frequently stop the test to add sand, which improves the efficiency of the test. Sand is introduced into the interior of the culvert 2 through the sand inlet 7, and the flow rate of sand can be accurately controlled. In this way, the input amount of sand can be adjusted as needed during the test to adapt to different test conditions and research needs, which improves the flexibility and controllability of the test. The compressed air ejected by the air nozzle 5 can blow the sand out of the culvert 2 to achieve the movement and flow of sand in the test. The existence of the air nozzle 5 can simulate the air flow in the actual project, which is closer to the mixed flow of water and sand in the real environment. The function of the air nozzle 5 can also achieve uniform distribution of sand. By ejecting compressed air upward from the bottom of the culvert 2 through the air jet 5, the sand can be fully suspended in the air, thereby achieving uniform distribution of the sand. This helps to simulate the water-sand mixed flow in actual engineering and improve the reliability and authenticity of the test. The lower surface of the culvert 2 is provided with a liquid inlet 3, and the interior of the culvert 2 is connected to the water pump and the water source through the liquid inlet 3. Through the connection with the water pump and the water source, water can be easily introduced into the interior of the culvert 2. In this way, it can be ensured that there is sufficient water supply during the test, and there is no need to frequently stop the test to add water. This improves the efficiency of the test and is particularly important in large-scale tests because the supply of a large amount of water may be difficult. Water is an important component of the mixed flow of sand and water. By connecting with the water pump and the water source, the water supply can be flexibly controlled during the test to simulate the water-sand mixed flow in actual engineering. This helps to more accurately study and analyze the behavior of the water-sand mixed flow and provide a reference for engineering design and practical application. Through the control of the water pump, the flow rate and pressure of the water can be adjusted. This makes it possible to flexibly adjust the water input amount as needed during the test to adapt to different test conditions and research needs. Adjustable water flow and pressure are very important for simulating different flow patterns, exploring water flow characteristics and evaluating engineering performance.
[0041] A sand swallowing tester based on Example 1 is used as follows:
[0042] The tester is composed of a lower hopper 1, a culvert 2, a bracket 4 and a retaining frame 6, and has a relatively simple structure and is easy to manufacture and install, which makes the maintenance and operation of the tester more convenient.
[0043] The compressed air flow rate can be controlled by connecting the air nozzle 5 and the air pipe to the compressed air source. In this way, the gas flow rate and pressure in the culvert 2 can be adjusted to control the swallowed sand. External air is added into the culvert 2 to increase the gas flow rate, thereby improving the reliability and accuracy of the test.
[0044] The sand is loaded into the culvert 2 through the lower hopper 1 and the sand inlet 7, so that a stable supply of sand can be achieved. The funnel-shaped guide groove 8 can guide the sand to flow toward the air nozzle 5, ensuring that the sand enters the culvert 2 and is blown out by the air nozzle 5. This can ensure the uniform distribution and consistency of the sand during the test.
[0045] The culvert 2 is connected to a water pump and a water source through a liquid inlet 3, so that water can be easily provided. In this way, water can be added during the test to simulate the mixed flow of water and sand in actual conditions, which is closer to the actual engineering environment.
