Problems solved by technology

[0005] 1. The automation degree of the existing test technology scheme is low, and each test step needs to be manually operated, which is prone to misoperation and lead to test failure
[0006] 2. There are many performance points in the test of oil mist separator. Once the test fails, the test of this performance point needs to be repeated. Manual operation can easily increase the number of repeated tests.
[0007] 3. The existing test technical scheme has a single function, and the test equipment needs to be modified and re-adjusted for other performance tests. The test cycle is long, and the existing test technical scheme can only test the separation rate under normal temperature air, and cannot detect Precise temperature control, the viscosity of lubricating oil is high at room temperature, the lubricating oil is directly passed into the pipeline, the atomization efficiency is low, resulting in the lubricating oil being blown into the oil mist separator by the air in the form of oil droplets, and the oil mist cannot be guaranteed 3 %-4% lubricating oil content, resulting in a high separation rate in the test, unable to ensure whether the product is qualified
[0008] 4. The existing test technical scheme does not process the separated exhaust gas, which causes the lubricating oil in the exhaust gas to enter the atmosphere and pollute the surrounding environment
Operators are vulnerable to injury from high-speed rotating machinery while performing manual operations during the test

Description

technical field [0001] The invention relates to the technical field of fully automatic product performance testing, in particular to an oil mist separation and transfer test bench; in addition, the invention also relates to a testing method for an aviation oil mist separator. Background technique [0002] The oil mist separator is an important component of the aircraft. It recovers the lubricating oil atomized in the exhaust gas during the flight of the aircraft, reducing the consumption of lubricating oil and exhaust pollution. The separation rate of the oil mist separator when working at a specific temperature, flow rate, and rotational speed is an important indicator for evaluating whether the product performance is qualified. Indicators, the separation rate of the oil mist separator can only be installed and used if it reaches a qualified level. [0003] The current method of testing the performance of the oil mist separator is manual testing. Install the oil mist separ...
