一种新型甲烷传感器调校装置通气嘴的设计

Design of ventilation nozzle of a new methane sensor adjusting device

甲烷传感器作为煤矿井下监测有毒有害气体的主要设备,对于煤矿的安全生产起着举足轻重的作用。所以甲烷传感器的调校也是一项非常重要的工作,本文主要针对目前用于井下现场调校的便携式甲烷传感器调校装置存在的缺点和不足,设计了一种新型的甲烷传感器调校装置通气嘴。

Methane sensor,as the main equipment for monitoring poisonous and harmful gas in coal mine,plays an important role in the safety production of coal mine. Therefore,the calibration of methane sensor is also a very important work. This paper mainly designs a new type of ventilation nozzle of methane sensor calibration device,aiming at the shortcomings and shortcomings of the portable methane sensor calibration device currently used for downhole field calibration.
