中文摘要:
      为了保证航空发动机燃油柱塞泵性能试验台测试结果的稳健性,以便准确测试燃油柱塞泵的性能状态,基于燃油柱塞 泵液压原理,建立了其数学模型,并结合其性能试验台的液压原理,确定了影响测试结果稳健性的5种主要因素分别为柱塞泵入 口压力、控制油压力、出口压力、排油压力及燃油温度。基于燃油柱塞泵的主要测试性能,研究了5种因素对燃油柱塞泵性能测试 结果的影响。结果表明:在进行燃油柱塞泵性能测试时,泵出口调压阀的压力控制稳定性、排油压力以及燃油温度都会对测试结 果产生较大的影响;在性能测试给定的公差范围内,柱塞泵入口压力和控制油压力的波动对性能测试结果影响极小。在进行燃油 柱塞泵性能测试时应重点关注出口压力、排油压力及燃油温度,以提高测试结果的稳健性。
英文摘要:
      In order to ensure the robustness of the test results of the aeroengine fuel plunger pump performance test-bed and accurate? ly test the performance of the fuel plunger pump, mathematical model of the fuel plunger pump was established based on the hydraulic prin? ciple of the fuel plunger pump. Combined with the hydraulic principle of the performance testbed, five main factors affecting the robustness of the test results were determined,namely the inlet pressure of the plunger pump,the control oil pressure,the outlet pressure,the dis? charge pressure and the fuel temperature. Based on the main test performance of the fuel plunger pump,influences of the five factors on the performance test results of the fuel plunger pump were studied. The results show that during the fuel plunger pump performance test, the pressure control stability,discharge pressure and fuel temperature of the pump outlet regulator exhibit significant impact on the test re? sults. The fluctuations of inlet pressure and control oil pressure of the plunger pump have negligible influence on the performance test re? sults within the given tolerance limit of the performance test. During the performance test,the focus should be on the fuel plunger pump,the outlet pressure,discharge pressure and fuel temperature to improve the robustness of the test results.
