颚式破碎机轴承端盖密封改进及应用

Improvement and Application of Bearing Ends Cover Seal of Jaw Crusher

针对颚式破碎机采用迷宫密封,在恶劣工况下极易造成轴承端盖密封失效、杂质侵入造成轴承早期异常磨损、整体使用寿命短的问题,进行了密封性能改造优化,装机后颚式破碎机使用寿命由3个月提升到12个月以上,单台颚式破碎机维护成本降低了约9万元/a。

Labyrinth seal is used by jaw crusher,it is easy to cause failure of cover seal of bearing end,impurities intrusion cause early abnormal abrasion of bearings,the overall life is short,inorder to solve the above mentioned problems,the optimization transformation of seal performance was carried out,then the life time of jaw crusher was increased from 3 months to over 12 months,the maintenance costs of single jaw crusher was decreased about￥90 thousand Yuan per year.
