When mine pit tunneling tunnel, breathes the fresh air for the supplies staff, the noxious gas which the dilution tunneling working surface's gas and produces, the mine dust, the creation good working condition, must carry on to the tunneling working surface ventilates. At present carries on the well ventilated major installation to the tunneling working surface is the JBT series axial flow type ventilator.
This design's content is to the JBT62 axial fans flow type ventilator overall concept and the ventilator gross structure design, mechanical drive part design, to axial-flow fan principle of work, main operating mode parameter significance grasping. The actual content includes: Ventilates the way the choice, the gross structure plan determination, the axis design and the examination computation, impeller's design examines and examines the computation, guide vane's design calculation, sparse class cover, diffuser and current collector design and choice, shell's design, ventilator muffler design, electrical machinery's choice and fixed way design, components and so on shaft coupling, key and flange shaping examinations.
