压力开关低气压试验方法研究

Low Pressure Test Method of Pressure Switch

目的提高压力开关进行低气压试验时的合格率。方法针对系留气球上使用的压力开关的低气压试验方法进行研究,分析传统低气压试验方法的缺点,提出一种新型低气压试验方法。针对两种试验方法,开展对比试验。结果按传统低气压试验方法进行试验时压力开关的合格率为40%,新型低气压试验方法可以将压力开关的试验合格率大幅提高。结论新型低气压试验方法可以提高压力开关的试验合格率,新型低气压试验方法可以更客观地反映压力开关的实际工况。

Objective To improve the qualified rate of pressure switch in low pressure test. Methods Low pressure test methods of pressure switches to be used to tethered balloons were researched. Defects of traditional low pressure test methods were analyzed and a new low pressure test method was proposed. Contrast test on two test methods were carried out. Results The pass rate of pressure switches was 40% when the test was carried according to the traditional method. The new low pressure test method could improve the pass rate of pressure switches significantly. Conclusion The new low pressure test method can improve the pass rate of pressure switches and reflect actual conditions of pressure switches more objectively.
