Roots blower is one of the more popular operating ventilation equipments. The original two-blade Roots blower has been replaced by the current energy-saving, low-noise and environmentally friendly three-blade type. In recent years, professional blower manufacturers have been Conventional air-cooled, single-tank Roots blowers, and new products such as low-noise, double-tank, water-cooled, and oil-cooled Roots blowers have been gradually developed and put on the market. The structure of a Roots blower is simple which consists of a casing, a wall panel and two three-lobed impellers. Through the action of a pair of synchronizing gears, the two impellers are rotated in opposite directions at the same speed, and the suction chamber and the exhaust chamber are basically isolated by the small gap between the impellers. In that way, Roots blowers can achieve the purpose of blasting. Because the Roots blower adopts frequency conversion control, the air volume can be accurately controlled, and compared with valve control, it is more intuitive and convenient to adjust the air volume of the blower to meet the production needs; due to the use of frequency conversion technology, the motor realizes soft start, and there is no starting current impact. Now the frequency converter is used for soft start, and the starting current is not higher than the rated current 46A, which reduces the impact of the instantaneous increase of the blower outlet pressure on the blower, thereby prolonging the service life of the blower and other equipment; because the blower speed is reduced to 60% of the original, It reduces the vibration frequency of the blower and blower pipeline, reduces the original basic noise of the blower greatly , and prolongs the mechanical life of the blower, motor and bearing, and reduces the maintenance of the equipment.
