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 of high pressure blower directly connected with 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 large high-pressure air blower speed and pressure, and thus will have a greater aerodynamic noise. Furthermore Roots blower, the gap between the rotor and the rotor and the cylinder will cause gas leaks between directly connected 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. Roots blower advantages: (1) between the blower rotor and the rotor, the rotor and the housing to retain a gap between 0.2-0.5mm, there is no friction phenomenon, allowing a gas stream containing some dust; (2) Roots Compared with the water jet blower and water ring vacuum pump, "exhaust with water," the problem does not exist; (3) Roots blower reliable operation, easy maintenance and durability.
