Description

Technical Field

[0001] This utility model relates to the field of gear oil performance testing technology, and in particular to a gear oil anti-foaming performance testing device. Background Technology

[0002] In wind farms, testing the anti-foaming properties of oils is a crucial step in ensuring the normal operation of equipment, primarily targeting transformer oils, gearbox oils, hydraulic oils, and turbine gear oils. Commonly used testing methods include ASTM D892, ISO 12152, and IEC 61125. These methods assess the oil's foaming tendency and stability by introducing dry air at different temperatures and recording the volume of foam formation and dissipation. During testing, careful attention must be paid to temperature control, maintaining a constant airflow rate, and ensuring sample cleanliness to avoid errors. The quality of anti-foaming performance directly affects the lubrication, cooling, and insulation effects of the equipment; therefore, regular testing is necessary before new oils are put into use and during operation to ensure efficient equipment operation and extend equipment lifespan.

[0003] In the existing technology, some gear oil anti-foaming performance testing devices can only test one type of gear oil at a time during operation, thus failing to provide a direct comparison of the anti-foaming performance of two gear oils, which is very inconvenient. Some of the tools used in the gear oil anti-foaming performance testing device are detachable, but these tools are not easy to store after use, requiring the testing personnel to search for the testing tools before starting the test, wasting a certain amount of experimental time. Utility Model Content

[0004] The purpose of this invention is to provide a gear oil anti-foaming performance testing device that can simultaneously test two types of gear oil, and can intuitively compare the test results of both, and can conveniently store the experimental tools.

[0010] According to the gear oil anti-foaming performance testing device, the left side of the second housing is rotatably connected to a second door, and the left and right sides inside the second housing are fixedly connected to grippers.

[0011] According to the gear oil anti-foaming performance testing device, the measuring cylinder is located above the stabilizing claw, and the measuring cylinder is engaged with the stabilizing claw.

[0016] 2. Compared with existing technologies, this new method incorporates a first housing with a first door rotatably connected to its lower part. This allows the testing personnel to easily store the hoses used during the experiment by placing them inside the first housing and closing the first door after the experiment. Furthermore, the inclusion of a second housing with a second door rotatably connected to its left side allows the testing personnel to easily store the measuring cylinders after cleaning them, by inserting them into the clamps on either side of the second housing and closing the second door.

Flexible hoses 17 are provided on the upper and lower sides of the lower part of the first box 15. Timers 18 are provided on the upper and lower sides of the upper part of the first box 15.

[0027] The above structure, by providing an opening 4, allows the testing personnel to inject water into the testing tank 2 through the opening 4 before testing.

[0028] By incorporating a lamp body 6, which is electrically connected to a controller 23, the inspector can turn on the lamp body 6 via the controller 23. Under the illumination of the lamp bodies 6 on both sides, the inspector can observe the scale more clearly, thus enabling better inspection.

[0029] By installing a heater 7, which is electrically connected to the controller 23, the testing personnel can control the switch of the heater 7 through the controller 23. Under the action of the heater 7, the water inside the testing tank 2 reaches the specified temperature.

[0030] By providing a stabilizing claw 9, with the bottom inner diameter of the stabilizing claw 9 being slightly smaller than the outer diameter of the measuring cylinder 10, and the claw body of the stabilizing claw 9 being a metal claw with a certain degree of elasticity, when the testing personnel place the measuring cylinder 10 into the testing barrel 2, the stabilizing claw 9 can stably lock the measuring cylinder 10 to the bottom of the testing barrel 2, preventing the measuring cylinder 10 from floating up.

[0031] A first pump body 19 is fixedly connected to the upper surface of the first housing 15. A second housing 20 is fixedly connected to the left side of the workbench 1.

[0032] The above structure includes a controller 23, which is electrically connected to the first pump body 19 and the second pump body 24. Both the first pump body 19 and the second pump body 24 are air pumps, allowing the testing personnel to control the gas flow rate of the first pump body 19 and the second pump body 24 through the controller 23, so that the two can be adapted to the air flow rate required for the experiment.

[0033] Working principle: In this gear oil anti-foaming performance testing device, water is first added to the test tank 2 through opening 4. Then, the lamp body 6 and heater 7 are turned on via controller 23, allowing the lamp body 6 to irradiate the test tank 2 and the heater 7 to heat the water inside the test tank 2, preheating the water temperature to 24±0.5℃. Next, the gear oil to be tested is added to the measuring cylinder 10. The measuring cylinder 10 containing the gear oil is then placed inside the test tank 2. The hose 17 is then removed from below the first housing 15, with one end inserted into the output end of the first pump body 19 and the other end inserted into the air inlet of the air inlet pipe 12. The stopper 11 is inserted above the measuring cylinder 10, allowing the gear oil to soak in the gas diffuser head 13 for five minutes. After soaking, the first pump body 19 is turned on by the controller 23, and the air flow rate of the first pump body 19 is adjusted to 94±5 ml / min. At this time, a timer 18 is used to start timing from the appearance of the first bubble in the gas diffuser head 13. The air is ventilated for 5 min±3 s, and the timing is 5 min±3 s. After the air is ventilated, the first pump body 19 is turned off, and the volume of the foam is recorded. The volume of the foam is recorded again 10 minutes after the air is ventilated. Finally, the results obtained from the two tests are evaluated to complete the test of the anti-foaming performance of the gear oil.
