水力旋流器沉砂嘴大小,是其工作好坏的主要参数之一。我厂使用的φ200毫米水力旋流器的沉砂嘴,如用白口铁的,使用寿命仅7天左右;后来,采用衬胶的办法,也只使用20多天。由于沉砂嘴磨损快,降低了分级效率,更换频繁,造成不必要的停车和金属损失。在抓纲治国,深揭猛批“四人帮”,掀起工业学大庆运动的高潮中,针对这个问题,我厂采用一、 Hydrocyclone grit nozzle size, is one of the main parameters of its work is good or bad. I plant φ200 mm hydrocyclone Shenzui mouth, such as using white iron, the service life of only about 7 days; Later, the use of rubber lining approach, only use more than 20 days. As the grit nozzle wear fast, reducing the classification efficiency, frequent replacement, resulting in unnecessary parking and metal loss. In the climax of tackling the Gangchuk rule, deeply exposing and criticizing the Gang of Four and setting off a Daqing movement in industrial science, in response to this issue,
