Description

Technical Field

[0002] The gas bearing levitation test device is a specialized device used to test the "levitation" characteristics of gas bearings during startup. Its core function is to simulate actual operating conditions and detect various parameters such as air pressure, speed, suspension gap, and power consumption throughout the entire process from a static state to the formation of a stable gas film and the levitation of the rotor. This verifies the rationality, stability, and reliability of the bearing design. The gas bearing levitation test device typically consists of a gas source system, a bearing test platform, a measurement system, and auxiliary equipment.

[0003] In experimental setups, the gas storage tank is a crucial component of the gas supply system. Compared to conventional industrial gas storage tanks, those used for buoyancy tests have much stricter requirements. Surface cleanliness must be checked daily to prevent contaminants from entering the precision gas path. The surface also needs daily cleaning, using anti-static nylon or microfiber brushes and avoiding the use of hard brushes like metal ones that could scratch the surface. Currently, cleaning the surface of the gas storage tank is usually done manually by staff, which is time-consuming and labor-intensive, increasing the workload and fatigue of the workers.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Please see Figure 1-4 This utility model provides a new technical solution: a gas bearing testing device, including a gas storage tank 1, four support legs 2 fixedly connected to the lower side of the gas storage tank 1, the four support legs 2 being arranged in a circular array, an air inlet pipe 3 fixedly connected to the upper side of the gas storage tank 1, the air inlet pipe 3 communicating with the interior of the gas storage tank 1, an air outlet pipe 4 fixedly connected to the lower side of the gas storage tank 1, the air outlet pipe 4 also communicating with the interior of the gas storage tank 1, both the air inlet pipe 3 and the air outlet pipe 4 being equipped with switch valves, and a cleaning mechanism being provided on the gas storage tank 1, which can automatically clean the outer surface of the gas storage tank 1, the cleaning mechanism including two connecting rods 5, two limiting slide grooves 6, two first connecting blocks 7, two second connecting blocks 8, a lifting ring 9, two motor assemblies 10, two threaded rods 12, two connecting ring blocks 13, and two cleaning brushes 14.

[0034] Furthermore, two connecting rods 5 are respectively installed on the left and right sides of the outer surface of the gas storage tank 1. Limiting grooves 6 are provided on the opposite sides of the two connecting rods 5. Two first connecting blocks 7 are fixedly connected to the upper side of the gas storage tank 1. Both first connecting blocks 7 are L-shaped blocks and are symmetrically arranged. The sides of the two first connecting blocks 7 that are far apart from each other are fixedly connected to the two connecting rods 5. Two second connecting blocks 8 are fixedly connected to the opposite surfaces of the two connecting rods 5. Both second connecting blocks 8 are located on the lower side of the gas storage tank 1. The opposite surfaces of the two second connecting blocks 8 are fixedly connected to the left and right support legs 2. A lifting ring 9 is slidably installed on the outer surface of the gas storage tank 1. The lifting ring 9 is slidably connected inside the two limiting grooves 6. Two motor assemblies 10 are fixedly connected to the upper sides of the two connecting rods 5. Synchronous control is achieved through a synchronous controller. The output ends of the two motor assemblies 10 are fixedly connected to drive shafts 11. The lower ends of the two drive shafts 11 extend into the interior of the connecting rods 5 and the two limiting slide grooves 6. Two threaded rods 12 are fixedly connected to the lower ends of the two drive shafts 11. The lower ends of the two threaded rods 12 are threaded through the lifting ring 9. The lower ends of the two threaded rods 12 are rotatably connected to the bottom wall of the two limiting slide grooves 6. Two connecting ring blocks 13 are Velcro-attached to the inner surface of the lifting ring 9. Both connecting ring blocks 13 are semi-circular ring blocks. The two connecting ring blocks 13 are combined to form a circular ring. Two cleaning brushes 14 are fixedly connected to the inner surfaces of the two connecting ring blocks 13. Both cleaning brushes 14 can contact the outer surface of the gas storage tank 1.

[0035] Furthermore, at the start of operation, the lifting ring 9 is positioned above the gas storage tank 1. The operator then attaches the two connecting ring blocks 13 and the two cleaning brushes 14 to the inner surface of the lifting ring 9 using Velcro. The synchronous controller controls the two motor assemblies 10 to start synchronously. The two motor assemblies 10 then transmit power from their output ends, driving the two drive shafts 11 to rotate synchronously. The two drive shafts 11 drive the two threaded rods 12 to rotate synchronously. The two threaded rods 12 then move the threaded lifting ring 9 downwards. This, in turn, causes the two connecting ring blocks 13 and the two cleaning brushes 14 to move downwards synchronously. While moving downwards, the outer surface of the gas tank 1 is cleaned. After the lifting ring 9 moves to the position below the gas tank 1, the two motor assemblies 10 stop. Then, the synchronous controller controls the two motor assemblies 10 to rotate in opposite directions. As mentioned above, the lifting ring 9 will drive the two connecting ring blocks 13 and the two cleaning brushes 14 to move upwards. After the lifting ring 9 moves to the position above the gas tank 1, it stops. Then, the staff can easily disassemble the two connecting ring blocks 13 and the two cleaning brushes 14 for cleaning, ensuring that the dirt on the two cleaning brushes 14 can be cleaned in time, thus ensuring the cleanliness of the outer surface of the gas tank 1.

[0036] Furthermore, this method enables automatic cleaning of the outer surface of the gas storage tank 1 as needed, thereby reducing the area that staff need to clean manually and thus reducing their workload.
