的间隙主要有三个： There are three main clearances for roots fans :
The first is the gap between the blades, which is mainly controlled by the synchronous gear and the blade bearings.
The second is the gap between the wind blade and the box
The third is the gap between the wind blade and the side plate
The second and third are adjusting the clearance between the lining and the side plate in the casing. The majority of the said blades are caused by the bearing gap becoming larger. If it is not possible to replace the synchronous gear, it is recommended to use a better quality bearing. At least, the high-speed bearing of the tile shaft or the Luo shaft must be used without import. The gear wear can be judged according to the gear occlusion gap. If the gear wear exceeds the limit, the two synchronous gears can be turned over so that the gear can be doubled Service life, when adjusting the gap between the two blades, you must use a feeler gauge to measure more than 4 points along the length of the blade to ensure that the gap is uniform and consistent over the entire length.
