1, FBDCZ series of explosion-proof explosion-proof axial flow fan 4- NO.44, 24 machine number. In order to meet the needs of the various parameters of the ventilation network of large and medium-sized mines, fans of the series were 6, 8, 10. 12, a three-phase asynchronous motor, and adopts two different forms: leaf number grading (BDK62) FBDCZ (A) leaves for the total number of Z=32, FBDCZ (formerly BDK62) (B) the total leaf Z=24 tablets. After the above combination, so that FBDCZ (original BDK62) series fans a total of 90 specifications. It solves the problem that the model of mine main fan is less and the selection is difficult.
Static efficiency 2, FBDCZ series of draw out type of explosion-proof axial flow fan in more than 70% of the working range of Q=10.1 ~ 462.1m3/S (Q=606 ~ 2772m3/min), Pst=57.0 705.7mmH2O (i.e. Pst=559 static ~ ~ 6921Pa), covering a variety of different types of mine ventilation network parameters of large and medium-sized mines, the operation efficiency can be found in the static pressure more than 75%.
Explosion proof type of fan: flameproof type for coal mine
FBDCZ series of explosion-proof explosion-proof axial flow fan factory, divided into a fan, fan II, diffuser and diffuser four pieces of the whole factory. Before the factory has been made by the manufacturer in accordance with the technical standards, the pressure test of the airtight cover, therefore, under normal circumstances should not be removed. If the transmission is difficult, must be broken down, can be guided by the manufacturer on-site installation.
When installed, the collector must be placed in fresh air so that the air in the closed hood is free of gas.
The place of installation of the fan should be smooth, and according to the schematic diagram of the sample, auxiliary rail, the use of 24-38Kg/M light rail can be embedded in the cement on the ground, but also can be fixed on the sleeper.
