Lobe Roots Blower characteristics and uses the characteristics and uses of the blower housing ⒈ intake vent cover wall spiral straight lines form a triangle at the top of the structure and the composition of the impeller inlet and exhaust ports with the rotation of the impeller and the progressive opening Closed, low operating noise and no exhaust pulsation phenomenon. ⒉ clover between the blower wheel straight, just make sure the impeller side of the gap can be compared with the same size of the traditional two leaves Roots blowers with high efficiency. ⒊ take special shape of the rotor, the rotor is easy to keep a gap between each other, sealing performance greatly improved, so that efficiency is further improved. ⒋ using precision CNC machine tool production and quality control measures taken to improve on the rotor strict verification, to ensure that the operation of this machine is very stable. The gears are made of special steel ⒌ properly hardened, in strict accordance with the manufacturing precision gear grinding. Thus from gear harmful interference to the product completely ruled out. ⒍ fans are widely applied in light industry, chemical industry, textile, metallurgy, electric power, mining, fertilizer, petroleum, gas stations, ports, aquaculture, waste water treatment, fuel oil, jet fuel, pneumatic conveying and other economic sectors.
