The invention relates to a flow resistance measurement test system which comprises a measuring system, an oil supply system, an oil return system, a gas supply system and a flow adjusting system. The measuring system comprises a differential pressure transducer. The oil supply system comprises an oil tank, an oil pump and a deflation stop valve. The oil return system comprises an oil box and an oil return stop valve. The gas supply system comprises a nitrogen gas cylinder, a pressure reducing valve, a gas supply stop valve and a pressure meter. The flow adjusting system comprises a flow meter and a flow stop valve. The nitrogen gas cylinder is communicated with the oil tank sequentially through the gas supply stop valve, the pressure reducing valve and the pressure meter. One side of the oil tank is connected with the oil box through a pipe, the other side of the oil tank is connected with a tested product sequentially through the flow stop valve and the flow meter, and the tested product is connected with the differential pressure transducer and the oil box respectively. The flow resistance measurement test system can solve the problems of a flow resistance test of the product on the condition that a test medium is aviation kerosene, simulate a real working medium, meanwhile fully verify the working reliability of the product, and have the advantages of being more real in environmental simulation and better in test result.
Description
technical field [0001] The invention relates to a product test system, in particular to a flow resistance measurement test system. Background technique [0002] More and more aerospace products require that the simulated environmental test can be closer to the environment where the product is in the real working state. The stable working medium test will not be able to effectively assess the accuracy of the flow resistance of the product in the actual working state, even in product development. In the early stage, the simulation test of the real working environment has also become very important. Ordinary flow resistance measurement methods are complex and require error calculations to obtain results, resulting in poor accuracy. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned prior art, and provides a flow resistance measurement test system, which uses the real working medium aviation kerosene to replace the st...
