安装注意事项:

     有基础的必须按照安装尺寸,浇注混凝土基础,三个机脚位置须校正水平,并粉光,待干燥96小时后,在三个机脚位置放置5—10mm厚的橡皮垫,使基础达到减震之功用然后放置离心机,并旋紧螺母;无基础的则无须混凝土浇注。

    安装前必须谨慎保管,注意电机、电控装置、液压系统、气控系统的防潮及所有易锈零部件的防锈蚀,并注意对机器外表面的保护。

    电控柜(气控箱)应放置在干燥、通风和无腐蚀气体的地点,而且应在主机附近(可以隔离安装)。

    离心机安装及放置必须水平。

    机器一般为整机安装,不得拆卸,如确有必要,则装配后必须由制造厂技术人员对其进行确认。

    离心机在高速运转时有轻微振动,故与离心机连接的管道(进料管、出液管、洗涤管、排气管、在线清洗管、氮气管、压缩空气管、电缆管等)必须柔性连接,连接处必须有可靠的密封或绝缘装置。

    离心机应有接地装置,确保无渗漏和安全用电。

 

  日常保养:

    离心机运转前应先切断电源并先松开离心机刹车,可以手试转动转鼓,看有无咬煞情况。

    检查其他部位有无松动及不正常情况。

    接通电源依顺时针方向开车启动(通常从静止状态到正常运转约需40-60秒左右)。

    通常每台设备到厂后均须空车运转3小时左右,无异常情况即可工作。

    物料尽可能要放置均匀。

    必须专人操作,容量不得超过额定量。

    严禁机器超速运转,以免影响机器使用寿命。

    机器开动后,若有异常情况必须停车检查,必要时需予以拆洗修理。

    离心机工作时是高速运转,因此切不可用身体触及其转鼓,以防意外。

    滤布的目数应根据所分离物料的固相颗粒的大小而定,否则影响分离效果。另外滤布安装时应将滤布

密封圈嵌入转鼓密封槽内,以防物料跑入。

    为确保离心机正常运转,转动部件请每隔6个月后加油保养一次。同时查看轴承处运转润滑情况,有无磨损现象;制动装置中的部件是否有磨损情况,严重的予以更换;轴承盖有无漏油情况。

    机器使用完毕,应作好清洁工作,保持机器整洁。

     不要将非防腐型离心机与于高腐蚀性物料的分离;另外严格按照设备要求、规定操作,非防爆型离心机切不可用于易燃、易爆场合。
