注:由于泵用途较多,故密封材质(摩擦副)也有不同,为保证密封的使用可靠性
厂家推荐如下:
1.清水(不含颗粒物工况)--动环摩擦副选用(合金),静环摩擦副选用(石墨)
2.强腐蚀(含有颗粒物工况)--动环摩擦副选用(碳化硅),静环摩擦副选用(碳化硅)
3.含有颗粒且振动较大工况--动环摩擦副选用(合金),静环摩擦副选用(合金)
4.也可以根据客户要求定做。如没有要求则默认为(清水)
安装使用要求:
1、设备转轴的径向跳动应不大于0.04毫米,轴向窜动量不允许大于0.1毫米;
2、设备的密封腔部位在安装时应保持清洁,密封零件应进行清洗,密封端面完好无损,防止杂质和灰尘带入密封部位;
3、在安装过程中严禁碰击、敲打,以免使机械密封磨擦会破损而密封失效;
4、安装时在与密封相接触的表面应涂一层清洁的机械油,以便能顺利安装;
5、安装静环压盖时,拧紧螺丝必须受力均匀,保证静环端面与轴心线的垂直要求;
6、安装后用手推动动环,能使动环在轴上灵活移动,并有一定弹性;
7、安装后用手盘动转轴,转轴应无轻重感觉;
8、设备在运转前必须充满介质,以防止干磨擦而使密封失效;
