Roots blower principle blower rotated in opposite directions two impellers, since the gap between the impeller and the impeller, the impeller and the casing, the impeller and the wall between the minimum, so that the air inlet is formed a vacuum blower production, air under the atmospheric pressure into the air intake chamber, and then purchasing Roots blower, wherein two blades of each impeller and wall panels, cabinet constitutes a sealed chamber, the air in the intake chamber during the rotation of the impeller, by two The continuous strip forming the blade seal chamber to the exhaust chamber, and because the exhaust cavity of the impeller are engaged with each other, so that the air is squeezed out between the two blades Roots blower price, such a continuous non-stop operation, the air it continuously transported from the air inlet to the outlet, which is the entire work process Roots blower. Performance parameters are mainly a Roots blower, blower pressure, also known as pressure means increased gas pressure within the fan values ??are static, dynamic pressure and total pressure points. Fan pressure units kpa Mpa 2, also known as air volume flow blower to flow through the fan, said the volume of gas per unit of time. Fan flow unit m3 / min m3 / h 3, Roots blower fan input power is the power that the shaft power. And effective power turbine shaft power ratio is called the efficiency. Fan total pressure efficiency of up to 90. Roots blower power unit for KW. 4, fan speed, noise and vibration size is also an important indicator blower design parameters. Roots blower applications, blower, Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd.
