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 pass rate of the pressure switch during low pressure test. Methods Aiming at the low pressure test method of pressure switch used on tethered balloons, the disadvantages of traditional low pressure test methods were analyzed and a new low pressure test method was proposed. For the two test methods, carry out comparative tests. Results According to the traditional low pressure test method when the pressure switch pass rate of 40%, the new low pressure test method pressure switch test pass rate increased significantly. Conclusion The new low pressure test method can improve the test pass rate of the pressure switch. The new low pressure test method can more objectively reflect the actual operating conditions of the pressure switch.
