本文通过对WJ-6、WP-5、WP-8三机组的排温多点测试及401机组排气管进口3～4个测点和排气管出口10个测点测试,求出了置信区间;对401机按实测空气、燃油流量等参数算得的燃气初温精确度作出了估计,并分析了机组主要部件效率变化和输出功率变化时燃气初温和排温的变化范围。通过这些分析得出如下结论:401机排气温度计算值496℃,相应的控制值定为550℃是恰当的。
In this paper, WJ-6, WP-5, WP-8 three units of the temperature multi-point test and the 401 unit exhaust pipe imports 3 to 4 measuring points and exhaust pipe outlet 10 test points, obtained confidence Interval. The accuracy of the initial temperature of the gas measured by the measured air and fuel flow parameters of the 401 engine was estimated. The range of variation of the initial temperature and the temperature of the gas when the main components of the unit changed in efficiency and output power were analyzed. The following conclusions are drawn from these analyzes: It is appropriate for the 401 engine exhaust temperature to calculate 496 ° C and the corresponding control value to be 550 ° C.
