Common type blower features: 1, sealing structure is reasonable, oil and gas can not enter the chassis, so that the output air is clean and free of grease. 2, bearings, belt imported. Bearings are manufactured in Japan, the US manufacturing belt. 3, fan gear used by carburizing 20CrMnTi Roots blower, grinding, precision up to five sewage treatment blower tooth surface more resistant, can significantly reduce gear noise. Roots blowers are of volumetric rotary blowers, using two-lobed rotor relative motion within the cylinder to compress and transport gas rotary compressor. This blower is simple structure, easy to manufacture large-scale direct-attached blower for low pressure gas delivery and pressurized situations, also be used as a vacuum pump. Before starting to prepare: (1) Check the bolts and nuts of connection tightness. (2) Check the gearbox lubrication, so that the oil in the oil standard center position. (3) Check the belt tension and pulleys prejudiced. Voltage and frequency (4) Check the power supply; (5) check whether the meter normal Direct Connect Roots blower, if abnormal promptly notify maintenance personnel replacement. (6) the main valve on the pipe, fans need to run to open the outlet valve, the other fan outlet valve is not running in the "off" state, to avoid fan overload, damage to the machine.
