In the process of industrial water treatment, in order to accelerate the aeration rate, usually as a booster fan facilities, strong power, low noise fan, is undoubtedly the best choice.Blower fan volume, delivery and transfer is proportional to the number of air flow, blade impeller rotating once every two to three times the impeller suction, exhaust, compare two leaf type, decrease of pulse gas, the load change is small, high mechanical strength, low noise, small vibration, simple structure, stable running, has been widely used in many fields, including water treatment.First of all, you see in the blower and the development process, find a few fan water treatment product performance is good.Roots blower constant torque load, the savings rate and speed down to N % = the proportion of delta N %, though different from the ordinary fan, water pump energy saving rate is high, but its power is larger, not bad, as long as the furnace wall is a continuous 24 hours work, and began a long time.Therefore, the energy saving potential and high cost savings.Of the technical renovation of the roots blower in the change of the past to adjust export (import) refers to the production adjustment valve opening pressure or air, reduce labor intensity, adjust good timeliness, improve the product percent of pass, single - consumption decreased significantly.After the application of variable frequency energy saving technology in cement plant, will not only can save (save up to 30% - 30%) of electricity costs, improve product quality, but also increased the use of flexibility, adaptability, different technological requirements.Characteristics determine the wind not to close the hard disk of export or import way to adjust the air flow, and after the main process areas, to optimize the above measures, a large number of surplus air volume control blower can be bypass, cause a lot of fan energy consumption, due to wear and corrosion problems, by-pass valve requires constant maintenance.Mainly by the blower cabinet, clapboard and two impeller rotor components.Through role is a pair of synchronous gears in the opposite direction, make the rotor two constant speed rotation, rely on the impeller and the impeller, the gap between impeller and casing, is basically isolated between the exhaust and suction cavity, the means of rotating impeller, in order to promote gas quantity, the purpose of the explosion.
