The main features of the Roots blower Roots blower biggest feature is the use when the pressure within the allowable range to regulate the flow of little change, the pressure to select a wide range, with a forced gas transmission characteristics. When the transmission medium is not oil. Simple structure, easy maintenance, long life, low vibration machine. Vacuum pumps. Because of the periodic suction, exhaust and compression caused by fluctuating instantaneous isometric flow velocity and pressure, and thus will have a greater aerodynamic noise. In addition, the gap between the rotor and the rotor and the cylinder will cause gas leaks between clover roots blower, so that the efficiency is reduced. Roots blower displacement is 0.15 to 150 m3 / min, the rotational speed of 150 to 3000 r / min. Single-stage pressure ratio is typically less than 1.7 up to 2.1, you can use multi-level series. Lobe Roots Blower Features: 1, the amount of wind output is proportional to the rotational speed blower, clover-type impeller each rotation of the impeller is engaged by two for two, second suction and discharge compared with two leaf type, gas pulsation small, too small vibration, low noise, long distance and high pressure seal blower 3, gears 20CrMnTi material, the accuracy of GB / T10095 five precision (both higher than the national standard seven precision accuracy class), the tooth surface, the cone hole carburizing, quenching, hardness HRC56-62 4, the use of advanced composite impeller line purchase Roots blower, made by precision CNC machining gap even after impeller blower assembly model, volumetric efficiency can be greatly increased by 5 Lord, fuel tanks are made of splash lubrication, gears, bearing lubrication more secure and reliable purchase Roots blowers, blower, Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd.
