Product Description
YBT series mine flameproof axial flow local ventilators are mainly used for press-in local ventilation in coal mines with explosive risks of gas or coal dust. The fans are also suitable for metal mines, chemical mines, tunnels and other uses. For fan factories and mines, the temperature of the conveying medium shall not exceed 40°C, the temperature shall not exceed 95±3% (25°C) and it shall be non-corrosive.
Design and manufacture
1. The structure of the fan is mine flameproof axial flow type: the fan consists of seven parts: collector, impeller, motor, explosion-proof junction box, body, air outlet, and muffler (YBT-X). The body and structural parts are all welded by steel plates; the motor and impeller are directly connected, and the transmission is reliable; the whole machine has a simple and compact structure, is strong and durable, safe to use and easy to maintain.
2. The motor is a YB series mining explosion-proof two-pole three-phase asynchronous motor with a voltage of 380/660V. The motor base and the body are welded together, and the motor is directly cooled by the air flow delivered by the impeller.
3. The junction box of the motor is placed outside the body for easy wiring. There are six wiring terminals and one grounding terminal in the junction box. The user selects the wiring method according to the power supply voltage requirements; when the power supply voltage is 380V, the △ connection method is used. When the power supply voltage is 660V, the Y connection method is used. The motor of the fan is shipped from the factory. All are connected according to △.
4. The flange of the fan body is welded with grounding bolts for direct use on site.
5. On the flange flange of the muffler, there are evenly distributed small holes drilled for connecting the reducing nipple or directly connecting the plastic air duct. When a variable diameter nipple is used to connect the fan and the plastic air duct, the type of the variable diameter nipple can be made into a convergent type or a divergent type.
