Efficient Explosion-proof Ventilation Fan
Efficient explosion-proof ventilation fan driven explosion-proof axial flow fan consists of a water turbine, a frame, a casing, a rotating body, and an impeller. The water turbine is made of corrosion-resistant copper alloy precision casting. The casing is welded with austenitic stainless steel, and the impeller is cast with high-strength aluminum alloy. The sealing of the water turbine and rotating body adopts two layers of mechanical seal and packing seal. There is a safety ring made of brass between the casing and impeller, which is a spark free structure as a whole.
Overview
Advantages:
1.The impeller of the high-efficiency explosion-proof axial flow ventilation fan is placed at the lower part of the casing, and there is a turbine in the upper part of the casing. The turbine is connected to the impeller below the turbine through a transmission shaft.
2.Advantages of the utility model: It adopts a hydraulic driven fan to avoid generating electric sparks and igniting flammable substances, truly achieving the purpose of explosion prevention.
3.Using fluid mechanics theory, the impeller is designed as a surface undulating surface, so that the airflow generated by the impeller rotation has a three-dimensional effect.
4.The use of enclosed bearings reduces maintenance workload. Widely applicable, it can transport flammable, explosive gases, vapors, and toxic and harmful hazardous gases.
5.Two layers of mechanical seal and packing are used for sealing. The safety integral made of brass between the casing and impeller is a spark free structure.
