摘要
分析了VTC-90立式涡轮分级机的工作原理和结构特点。主轴采用两端两点支承且其组件采用整体吊装方式安装和拆卸;采用了独特的下支承定位固定方式;通过密封叶轮提供的气密封,防止气流“短路”,影响分级效率;独特的叶片组件结构提高了叶片和转笼的刚度。该机具有分级效率高,安装、维护简便的特点,将为国内超细粉碎行业提供分级效率高、产品性能稳定且安装、维护简便的新型分级设备。
The working principle and structure characteristics of VTC- 90 vertical turbine classifier were analyzed. The chief shaft was supported by two fulcrum bearings at both the two ends, and its component was entirely assembled and dismounted, A unique method was devised to allocate and fix the lower fulcrum bearing, With airproof impeller, ＂short circuit＂ of airflow was avoided. Furthermore, a unique impeller component increased the rigidity of impellers and tumbler. VTC - 90 vertical turbine classifier would bring in a new type equipment featured classification efficiency, stable capability, as well as simple installation and maintenance.
