这台快速检漏台用于夜视器件的检漏.与 ZLS—23型氦质谱检漏仪配套使用.它的特点是:(1)采用全金属系统,在满足生产要求的前提下尽量简化设备结构.各联接件均采用按国际标准的快速联接结构.(2)所有阀门均采用电磁阀,仅用四个按钮即可完成整个控制过程,操作简便,动作迅速可靠.(3)利用电阻真空计信号控制电磁阀的动作,可自动转换投入检漏状态.(4)通过设置活性氧化铝吸附挡油阱来克服粗抽机械泵的油蒸气污染,加上在氦质谱检漏仪的冷阱中灌注液氮的措施可以较好地解决对被检件的油蒸汽污染。
This quick leak detection stage is used for leak detection of night vision devices and is used in conjunction with the ZLS-23 Helium Mass Spectrometer Leak Detector. It features: (1) All-metal system simplifies to meet production requirements Equipment structure. Each coupling adopts international standard quick coupling structure. (2) All valves are solenoid valves, only four buttons to complete the entire control process, easy to operate, action quickly and reliably. (3) the use of resistance Vacuum gauge signal control the action of the solenoid valve, can automatically switch into the leak detection state. (4) Set active alumina adsorption oil trap to overcome the rough pumping mechanical oil vapor pollution, coupled with helium mass spectrometer leak detector cold The method of filling the well with liquid nitrogen can better solve the oil vapor of the test piece.
