YBT, FBY series flameproof axial flow fan, mainly used in underground coal containing gas or coal dust explosion danger for forcing type ventilation, this product is also suitable for metal mines, chemical mines, tunnels and other wind machine factories, transmission medium temperature does not exceed 40 degrees. The temperature is not greater than 95 + 3% (25 C) and non corrosive.
Structure and characteristics
1, YBT, FBY series flameproof axial flow fan in the structure in the form of mine explosion-proof axial flow fan is composed of: the collector, impeller, motor, explosion-proof junction box, a machine body and a hairdryer, muffler (YBT-X) composed of seven parts. The body and the structural parts are welded by steel plates; the utility model adopts the direct mode of the motor and the impeller, and the transmission is reliable; the whole machine is simple and compact in structure, firm and durable, safe in use and convenient in maintenance.
2, the motor for the YB series flameproof three-phase diode asynchronous motor, the voltage is 380/660V, the motor frame and the body into a whole body, the motor is directly cooled by the air flow impeller.
3, motor wiring box placed outside the body, easy wiring. The terminal box has six terminals and a grounding terminal, the user according to the power supply voltage required to select connection mode; when the power supply voltage of 380V, using the delta connection method, when the supply voltage is 660V, using Y method, the blower motor according to the delta connection.
4. The flange of the fan body is welded with ground bolt, which can be used directly.
5. In the flange flange of the muffler, evenly distributed small holes are used to connect the short or direct connection of the plastic duct. When the reducer is connected with the fan and the fan, the type of the variable diameter joint can be made into a convergent type or a diffusion type.
