Explosion-proof Axial Flow Fan

When installing a newly purchased ventilation fan, it is necessary to handle the installation site well, clean the roadway, hang the various components of the ventilation fan in sequence onto the laid steel rails, connect and tighten the components, and connect the power and instrument wires according to the motor user manual. The ventilation fan must be installed on the surface of the outlet of the branch air duct, with explosion-proof doors installed according to regulations, and ensure that the air exchange port of the partition chamber is connected to the atmosphere. Before installing a new ventilation fan, the following aspects should be checked: 1. Check whether the voltage of the motor and control cabinet match, and whether the insulation is qualified. 2. Before powering on, use a megohmmeter to check the cold insulation resistance value of the motor, which should be greater than 50 M Ω. 3. Is the gap between the blades and the casing (or protective ring) even?…
