| description | The utility model discloses an access door for a centrifugal fan, which belongs to the technical field of access doors and comprises a pressing block, a pressing handle, an access door plate and a volute plate. The pressing block is welded to the volute plate, and the pressing handle is arranged on the overhaul door plate through a rotating shaft. The pressing handle is rotationally embedded into a groove of the pressing block and buckles the maintenance door plate and the volute plate. The situation of leakage caused by the fact that holes are formed in the machine shell is avoided, the sealing performance is greatly improved, and the fan shell can be suitable for fans under complex working conditions.
本实用新型公开一种用于离心风机的检修门，属于检修门技术领域，包括压紧块、压紧把手、检修门板、蜗壳板；所述压紧块焊接于所述蜗壳板上，所述压紧把手通过转轴设置于所述检修门板上；所述压紧把手旋转嵌入所述压紧块的槽内并将检修门板与蜗壳板扣合；规避了在机壳上开孔，造成泄漏的情况，极大提高了密封性，可以适用于复杂工况的风机。 |
