摘　　要：全静压系统检查仪对飞机上该系统的气密性与仪表指示的准确性有直接影响。针对原检查仪存在的问题 ,研制了无油真空压力泵和以单片机为控制核心基于振动筒式压力传感器的测量显示组件 ,设计了新的检查仪。经实际使用表明 :该检查仪具有检测速度快 ,精度高 ,判读直观 ,操作简单 ,维修性好等特点 。Aero pitot-static pressure system tester has direct effects on the airtightness of the air- borne pitot - static pressure system and the accuracy of meter reading. In view of the problems present in the old tester, a new tester is designed by adopting the developed oilless vacuum pump and test - display unit based on chip computer and vibrating pot pressure sensor. The result of practical use shows that the tester has characteristics of quick testing speed, high precision, visual reading, simple operation and good maintainability, etc., thus solving the problem of oil leakage polluting the air source and some related air-borne equipment.
