摘要
系统地研究了紫外荧光法各参数对航天煤油硫含量测试结果的影响,分析了硫信号积分值随进样速率、进样量、负高压、裂解氧流量、氩气流量、进口氧流量和裂解温度的变化规律,得到了最佳测试条件。结果表明:进样速率、裂解氧流量、氩气流量、负高压是紫外荧光法精确测定硫含量的主要影响因素;最佳进样速率和最佳氩气流量会受航天煤油热裂解反应的影响,最佳裂解氧流量与进样速率有关,负高压范围由基线噪声情况确定,最佳进样量可根据负高压对最小进样量的影响来确定。本研究为紫外荧光法准确、高效地测定航天煤油硫含量提供了测试参数参考,也给探究最佳测试条件提供了试验方法。
The influences of various parameters of UV-fluorescence method on the test results of sulfur content of space kerosene were systematically studied.The laws of the change of sulfur signal integral value of space kerosene with injection speed,injection volume,negative high voltage,cracking oxygen flow rate,argon flow rate,imported oxygen flow rate and cracking temperature were analyzed.The optimal test conditions were obtained.The experimental results showed the main factors affecting the accurate determination of sulfur content by UV fluorescence method were injection rate,oxygen flow rate,argon flow rate and negative high voltage.The optimal injection rate and argon flow rate were affected by the thermal cracking of space kerosene,the optimal cracking oxygen flow rate was related to the injection rate,the negative high voltage range was determined by the baseline noise condition,the optimal injection volume was determined by the influence of negative high pressure on the minimum injection volume.This study provides a reference to measure accurately the sulfur content of aerospace kerosene by ultraviolet fluorescence method,and also provides an experimental method to explore the best test conditions.
