Explosion proof centrifugal ventilator are widely used in petroleum, chemical, electric power, military, medicine and other industries. It is to send and exhaust dangerous places and factories, mines, buildings and other ventilation
1. The impeller consists of a plurality of forward arc-shaped aluminum alloy blades, front discs and rear discs, all of which are made of mechanized molds. They are statically and dynamically balanced and verified to operate smoothly and reliably with good aerodynamic performance.
2. The casing is made of galvanized steel sheet, which is formed by spot welding after mechanized mold processing. The structure is firm and reasonable.
3. The motor support is formed by galvanized steel sheet through mechanized mold.
4. The motor uses a single-support outer rotor type motor. The impeller is fixed on the motor casing. The motor support end is fixed on the motor support. The motor support is fixed on the top plate of the casing, and the impeller is directly driven by the rotation of the motor casing.
a. The altitude does not exceed 2000m;
b. Ambient atmospheric pressure 80~110kPa;
c. Ambient temperature -20~40 °C;
d. The relative humidity of the surrounding air is not more than 95% (at 25 ° C);
e. There are flammable gases in Groups IIA to IIC and T1 to T4, and explosive gas mixture formed by steam and air in Zone 1 and Zone 2 ;
f. where there is no significant vibration;
g. In an environment where there is no damage to metal-insulated gases and vapors.
h. Impurities in the gas: no viscous substances in the gas, the dust and hard particles contained in the gas are not more than 12mg/m3;
i. Gas temperature range: -20 ° C ~ 8O ° C;
j. This series of fans is only suitable for indoor installation, with the motor power cable as the top. It must not be installed upside down or installed sideways, otherwise it will affect the service life of the motor. If it is to be installed outdoors, the rain protection measures of the motor must be considered.
