液压油滤芯用于各种油系统中滤除外部混入或系统运转中内部产生的固体杂质,主要安装在系统中的吸油路上、压力油路上、回油管路上、旁路上,单独的过滤系统上。工业用液压油在使用过程中由于种种原因会混进去一些杂质,主要的杂质有机械杂质,水和空气等,这些杂志会造成腐蚀加快,增加机械磨损降低工作效率,使油品变坏降低设备使用寿命,严重时会产生油路堵塞造成生产事故。混凝土输送泵的液压油过滤,工程机械的液压油过滤,液压站液压油的过滤。
回油过滤器直接安装在油箱盖板上,过滤器滤头露在油箱外,回油筒体浸入油箱内,进油口设有管式与法兰式连接,从而简化了系统管路。使系统布置较为紧凑,安装连接更方便。
2.设置滤芯污染发讯器,油路旁通阀,提高液压系统的可靠性;
当滤芯被污染物堵塞或系统液温过低,流量脉动等因素造成进油压力为0.35mpa时,发讯装置便发出讯号指示。应及时更换滤芯或提高油液温度。如此时不能马上停机处理这些故障时,设在滤芯下部的旁通阀自动开启工作(旁通阀开启压力为0.4mpa),以保护过滤器及液压系统正常工作。
3.设计采用直回滤油,使更换滤芯或向油箱加油非常方便;
只需旋开过滤器滤盖(清洗盖)即可更换滤芯或向油箱加油,并在滤头设有2只m18×1.5油口,可在任何一方安装发讯器或系统中少量油液流回油箱过滤之用。
4.具有液流扩散器rfa-250×10f-c/y矿山回油过滤器滤芯
扩散器设置在回油筒体底部,能使回油的介质平稳地流入油箱内,不易产生气泡,从而减少空气重新进入,并减弱已沉积的污染物骚动。
5.滤芯采用玻璃纤维过滤材质;
具有过滤精度高,通油能力大,原始压力损失小,纳污量大等优点。其过滤精度以绝对过滤精度标定,过滤比β3,β5,β10,β20≥200,过滤效率η≥99.5%
