Common type blower features: 1, Roots blower sealing structure is reasonable, oil and gas can not be transported into the cabinet blower powder, therefore, the output of the air blower to clean dust, grease-free. 2, bearings, belt imported. Bearings are manufactured in Japan, the US manufacturing belt. 3, fan gear used 20CrMnTi carburizing treatment, grinding, precision up to five, the tooth surface more resistant, can significantly reduce gear noise. Roots blower works: the enclosure has two special shape in turn, often Samsung-shaped or kidney-shaped, between the two rotors, a very small gap between the rotor and the casing, so that in turn can freely rotate and No excessive leakage. Two revolutions in the opposite direction of rotation, and allow gas to the suction side of the casing, while the other side is discharged. Such as changing the rotation in the direction of rotation, the suction port and discharge port are interchangeable. Roots blower and wind speed is proportional to, and almost free from pressure changes affect exports. Roots blower must turn when transporting particles Roots blower, air volume can be roughly unchanged, so called volume blower. This type blowers gas transmission capacity range is 2 ~ 500m3 / min, the pressure in the export table within 80 × lO3Pa, but the pressure is higher in the table about 40 × lO3Pa time efficiency. Roots blower outlet gas surge tank should be installed and configured valve. Dust blower, blower, Zhucheng East Han Machinery Co., Ltd. is provided by Zhucheng East Han Machinery Co.
