　　普惠风机的基本结构与工作原理

　　普惠风机（通用型工业风机）通常由叶轮、机壳、电机和传动系统四大部分组成，采用离心式或轴流式设计。离心风机通过叶轮旋转产生离心力增压，适合10-3000Pa的中高压场景；轴流风机则依靠螺旋桨式叶轮推动空气轴向流动，适用于大流量需求。标准型号电机功率覆盖0.75-315kW，采用直接驱动或皮带传动方式。某污水处理厂案例显示，选用普惠离心风机替代老旧设备后，气量提升25%而能耗降低18%，投资回收期仅1.8年。

　　Jiuzhou Pratt & Whitney fan Co., Ltd. was founded in 1996, with its headquarter in Nanhai District, Foshan City. It is an enterprise focusing on environmental protection ventilation equipment and integrating R & D, production, sales and service. Now it has become a domestic fan product manufacturer. The factory covers an area of 115000 square meters, and the standard workshop area is 100000 square meters. It has laser, plasma, machining center, die casting, dynamic balance and other general and CNC equipment as well as precise measuring tools and testing instruments. It has built multiple production lines, used the auxiliary design system, applied the MGS, cat automatic testing system, and built the fan pneumatic performance testing center and motor performance testing center 。 The company cooperates with a number of colleges and universities in technology research and development and talent cultivation projects, which has brought up a number of professional and technical talents. It pays special attention to quality, brand and technological innovation, adopts international standards for construction, and is recognized as a national 4A level standardized good behavior enterprise, which lays a solid foundation for product research and development and quality control. It has a perfect marketing network and continues to meet customer needs In order to pay attention, we should actively implement the strategy of scale and constantly explore the international and domestic markets.
