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 direction of rotation of shaft rotation in the oxygen supplying blower, 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 switch constant air volume can be roughly unchanged, so called volume blower. This type blowers gas transmission capacity range is 2 ~ 500m3 / min, the export table in less than 80 × lO3Pa pressure ventilation duct blower, 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. Roots blower is to keep a small gap between the front and back cover and fan impeller end, driven by synchronous transport gear rim from the fan inlet to the discharge side of the housing wall of a machine equipment, mainly used to force gas delivery. The reason blower usage growth, because many industries have been involved in some of the Roots blower use, so began to put into use. Roots blowers started up in wastewater treatment equipment for washing Roots blower, and now the industry has a lot of water to deal with. Put into use after the winery is the oldest, blower into the use of which the effect is very obvious Roots blower, not only to improve the quality of wastewater, but also in the odor has also been improved, and constantly put into use winery sewage treatment are slowly resolved.
