变温润滑油涡轮流量计修正技术研究
|
摘要
为研究以变温航空润滑油为工作介质的涡轮流量计仪表系数修正方法,利用变温航空润滑油流量标准装置对4支涡轮流量计在多个温度点下进行了校准试验,通过双指数衰减函数对校准结果进行拟合修正。结果表明,各温度点和流量点涡轮流量计仪表系数与校准结果误差小于1%,修正方法具有较好的通用性。
In order to study the correction method of instrument coefficient of turbine flowmeter that works in aviation lubricating oil with variable temperature,in the study,four turbine flowmeters are calibrated at different temperature points with the flow standard facility which works with aviation lubricating oil and the temperature can be regulated. The double exponential decay function is used to fit the calibration result,and the error of the meter coefficient after corrected at each temperature and flowrate is less than 1% by the fitting correction,and it's sure that the correction method is universal.
