FBDCZ (original BDK) series (d I)
Explosion proof axial flow fan
An instruction manual
Characteristic
The machine adopts rotary structure, namely two same types of fan docking, two impeller rotating in the opposite direction, can save the guide vane guide vane and reduce loss, improve efficiency. The motor and the impeller in the form of direct connection, due to the simple structure, in addition to the regular motor oil refueling, generally do not need maintenance, long-term continuous operation.
This series fan motor power is less than 200KW, supporting YB series of derived YBF series flameproof motor, the motor is installed in the main air duct of the sealed cover, the sealed cover with a certain pressure, and it can make the gas gas motor and fan flow in isolation, airtight cover is provided with two rows streamline the wind pipe through the main duct and the ground atmosphere, so that fresh air into the sealed cover, but also can make the cover of air to maintain positive pressure in the fan operation. The motor is always under the condition that the gas concentration is less than 1%, which meets the requirements of safety and explosion protection.
The highest unit fan static efficiency is 86%, efficient region is broad, the main air duct is a stabilizing ring, fan performance curve without hump, no surge, operation can be stable under the condition of no resistance. Low noise, you can reverse the wind, the machine is stable, the machine vibration is small, the fan and diffuser are installed on the wheel with a flat car, you can run for a long time.
6, this series fan blade all can be adjusted, is divided into 45o, 40o, 35o, 30o and 25o before and after the five working angle, angle can be consistent, can also be different, and can be adjusted to any angle under 45o operation. Can run one of the typhoon machine, therefore, adjustable range is extremely broad. In the initial stage of mine production, only one fan can be run.
