The main application of a suction blower, the blower impeller cycloid impeller, high volumetric efficiency, internal leakage stingy conveying blower, low energy consumption. 2, casing, impeller, wallboard, siding, gear box made of high strength gray cast iron (HT250) manufactured, imported resin sand production line aeration blower, imported CNC machining. 3, transmission gear material used 20CrMo alloy steel, carburizing, quenching, grinding, precision rating of level GB10095-88 5, tooth surface hardness HRC56 ~ 62. Roots blower installation because it is the high-speed operation of the machine, it will vibrate, but also because of its pulsating internal air around, but also increased the blower vibration, so needs to be fixed on the ground Roots blowers installed. According to the fan on the model, according to the fan size on the ground in a position corresponding to 150 * 150mm square and 300mm digging deep square pit and buried bolt, then dust blower through bolts and nuts to connect the fans, finally in square pit fills with concrete, concrete and other fixed later, and then forced to tighten the nut, the fan base and concrete blower firmly connected together, so that you can reduce the vibration displacement blower in operation, improve equipment operational safety, and due to reduced vibration, thus greatly extending the life of the fan.
