How it works: positive displacement blower fan, air volume delivered is proportional to the number of revolutions, clover type impeller rotates once every two impellers by three times the suction and discharge, compared with two leaf blower-type pneumatic conveying gas pulsation is reduced, small changes in load, high mechanical strength, low noise, vibration small. In the two-phase line shaft flat has two clover-type impeller, and always maintain a slight gap between the wheel and the oval hole in the chassis side and all three impellers, due to uniform rotation of the impeller opposite directions, so that the box and the impeller is surrounded by a certain amount of gas delivered to the suction side of the discharge side. Each branch has always maintained by the synchronization gear wheel correct phase blower, will not touch each other and, therefore, can be high-speed, no internal lubrication blower particle transport, and simple structure, stable operation, stable performance, adapt more such use has been applied to a wide range of fields. Characteristics of a Roots blower, due out in the form of clover with a rotor structure and reasonable housing outlet structure, so the fan vibration, low noise. 2, the overall structure of the impeller and shaft and impeller wear, fan performance enduring, long-term continuous operation. 3, complete models of large direct-attached blower, which can meet the needs of different users for different purposes. Roots blower is widely used throughout the petrochemical, building materials, electricity, metallurgy, fertilizer, mining, ports, textile, food, paper, aquaculture and wastewater treatment, environmental protection industry and many other areas, mostly for conveying air, can also be used conveying gas, hydrogen, acetylene, carbon dioxide and other flammable, explosive and corrosive gases.
