我厂使用的6НП砂泵的密封很不合理,多年来漏水跑煤现象严重(有时每小时跑煤一吨以上)。为了解决上述问题,工人们打破洋框框,在反复试验的基础上,将原设计采用的离合器密封改为三层油封密封(见图)。改进后的密封有以下优点: 1、解决了砂泵的漏水跑煤问题。过去用橡皮套,新换一次,不到一个星期就
The sealing of 6НP sand pump used by our factory is unreasonable. There is a serious leakage of running coal for many years (sometimes more than one ton of coal per hour). In order to solve the above problems, the workers broke the box and changed the clutch seal used in the original design to a three-layer oil seal seal on the basis of trial and error (see figure). Improved seal has the following advantages: 1, to solve the sand pump leakage running coal problems. In the past with a rubber case, the new change, less than a week on
