气密性检查

环境温度对固体火箭发动机气密性检查影响分析

Influence of ambient temperature on solid rocket motor airtight test

为此，采样人员在采样前必须进行误差分析，定期校准采样器，对采样系统进行气密性检查，按时校准流量，掌握程序的设置方法。

Therefore , sampling workers must make error analysis before sampling , adjust the sampling equipment regularly , check the airtight of sampling system , adjust flow regularly and grasp the setting of programme .

该系统的设计实现可以完成全静压系统的仪表和设备的工作性能、状态及系统气密性的检查，具有自动化程度高、检测速度快和高精度、易操作的特点。

The design and implementation of the system can complete the test of the instrumentation and equipment performance , status and air tightness of the pitot-static pressure system with a high degree of automation , testing speed and high-precision , easy-to-operate features .
