Mine Shaft Fan Technology: Monitoring of Fans
2015-12-23 10:11:17

Mine shaft ventilator technology: In order to prevent the fan from running in the surge zone, an anti-surge alarm device is installed on the fan. The device consists of a Bitman tube and a differential pressure switch installed in front of the moving blades of the impeller. The Bitman tube is used to sense strong pulse pressure. The differential pressure switch converts this pressure into an electrical signal and outputs an alarm.
