FBDY series mine explosion-proof press-fit counter-rotating axial flow local ventilator fan
FBDY series mine explosion-proof press-fit counter-rotating axial flow local fan is a new type of local fan with a wide range of uses. The machine has the characteristics of compact structure, low noise, high wind pressure, high efficiency, good anti-wind performance, stable operation in a small flow area, and a wide range of efficient applications. According to the different ventilation requirements of the length of the working face and the roadway, it can be used in the whole machine and can be used in stages, so as to reduce energy consumption and save energy.
The max ventilation distance can be at 10KM.
Power from 1.1kw~75kw.
Design advantages
1. The fan adopts a panel-type muffler structure. The entire outside of the flow channel of the fan is made of flexible materials, which greatly reduces the noise radiated outside the body by high-speed airflow. The noise when the fan is running is also relatively soft.
2. The outer diameters from the fan rectifier cap to the muffler core, to the motor base and the rear muffler cone must be consistent to ensure that the flow channel in the fan body is smooth, and also improves the pressure coefficient of the fan and increases the delivery rate. Wind distance.
3. The panel-type muffler structure uses a fixed end and a movable installation form for the muffler cotton, so that the muffler cotton can be replaced after failure, ensuring the muffling effect and extending the service life of the ventilator.
