Common type blower features: 1, casting resin sand casting process, by the Shandong Light Industry Machinery Factory foundry production boiler air blower, sixteen fan casting quality fully guaranteed. 2, in strict accordance with involute impeller design theory and computer simulation on the gas, biogas feed pressure blower, installed before equilibrium experiments done repeatedly rotating blower, fully guaranteed involute meshing characteristics, effective reduce leakage and improve efficiency. Characteristics of Roots Blower: Roots blower is to keep a small gap between the front and back cover and fan impeller end, driven by synchronous transport gear rim from the fan inlet to the discharge side of the housing wall of a machinery and equipment, is mainly used to force gas transportation. Roots blower value is not needed in the course of the lubricating oil washing Roots blower, it is very easy to use; and out of the outlet structure of the inner rotor structure and the use of clover in the form of reasonable housing, so the fan vibration, low noise. For noise pollution is also a good guarantee, fan performance enduring, long-term continuous operation; high efficiency, can improve our results, we work to maximize revenue.
