Desulfurization fan | Desulfurization Roots blower | Zhangqiu fan manufacturer

Desulfurization fan, desulfurization Roots blower is what we usually call two-blade Roots blower and three-blade Roots blower. Desulfurization fan The main features of the desulfurization Roots blower are the involute shape of the impeller, which is advanced and reasonable, with high efficiency of the whole machine, excellent material and long service life. Low noise. The desulfurization fan adopts forced lubrication, has high pressure boost, high rotor balance, small vibration, and long-term operation is safe and reliable. The casing of the desulfurization Roots blower adopts a split structure, which is convenient for maintenance. The desulfurization Roots blower has a compact structure, small size, light weight, and is easy to use and maintain. East China Fan Co., Ltd. specializes in the production of various types of desulfurization Roots blowers. The characteristic spiral shape is the above fixed spiral method. The air inlet and exhaust shielding lines of the casing are cut into the spiral, and the triangular air inlet and exhaust openings formed by the smooth line on the top of the rotor are gradually opened by the rotation of the rotor. The air outlet near the exhaust fan of this fan does not open or close instantly like the old Roots blower, so the operation sound is small and the exhaust pulsation is low. The rotor is a three-bladed linear rotor, so it does not collide with each other due to slight axial displacement like a spiral rotor. Therefore, it is enough to ensure the gap between the rotors in the cross-section. There is no need to add axial positioning like the rotor spiral type, so that the gap becomes larger. The efficiency of this type of fan is better than that of rotor spiral fans of the same size. Precision CNC machine tools are used to mass-produce rotors, and perfect measures are taken for precision management. Therefore, there is no performance error between each fan. In addition, the rotor has been balanced during the manufacturing process. Therefore, the rotor does not retain the slight imbalance that it did in the past. The unit is almost completely vibration-free. Use advanced synchronous drive gears to extend service life and reduce noise.
