摘要
The purpose of the notification is to stabilise the pressure in the bottom de -pressurisation network in underground mining installations and to use a device to do so.The way to stabilise the pressure in the bottom deflection network is to reduce the flow resistance in the pipeline,where the pressure is too high in relation to the pressure at the point of connection to the manifold, by means of a flow machine built into that manifold.A device for the purpose of stabilising the under -pressure in the underground mining network,is an equipped fan on the defrosting line and contains an immediate opening fan in case the fan is switched off (5),and the required pressure at the outlet of the device and its performance are automatically adjusted by changing the engine speed (6) of the fan.
