The main fan impeller, housing, air inlet, adjust the door and transmission parts. 1. Impeller: from 12 miter type blade airfoil backward arc welding in the middle of the cone and plate-shaped front plate after plate. As a result of the wing-shaped leaves, ensuring fans of high efficiency, low noise, high strength. Impeller static and dynamic balance correction M5-29 pulverized coal boiler fan, it is smooth. The same number of aircraft through the same draft fan impeller. In use, excessive or insufficient flow often occurs. The reason for this phenomenon more Y5-47 boiler fan, if occurred in the course of this phenomenon is due to the large, sometimes small pipe network resistance. If it is in use, a long-time gradually decreased, mainly due to network congestion. Zibo boiler fan manufacturer _ Blower (certified) _ boiler fan provided by Zibo Blower Factory Co., Ltd.
