磨煤机除各种检查门、检修门与本体之间及各结合面法兰之间的泄漏外,其主要泄漏发生在运动部件与静止部件之间,即:拉杆与中架体,磨盘支座与下架体密封环及磨辊密封处,其主要原因是磨机处于正压运行,磨机内部压力高于外部大气压力。在各结合面间加装石棉绳,使之受压缩变形是有效防止静止件间隙漏粉的方法。但是如前所述的动静件之间不可能靠上述结构密封。
In addition to various coal grinding machine inspection door, between the maintenance door and the body and between the joints of the flange leakage, the main leakage occurred between the moving parts and stationary parts, namely: the lever and the frame, the disc support The main reason for the seat and lower frame body sealing ring and grinding roller seal is that the mill is in positive pressure operation and the internal pressure of the mill is higher than the external atmospheric pressure. Asbestos rope installed in the combination of the surface, so that the compression deformation is effective to prevent static gap leakage method. However, as described above, it is impossible to seal between the static and dynamic components by the above structure.
