“矿山机械”1989年11期刊登了“国产铲运机的问题及改进意见”一文,文中指出了国内某厂生产的0.75m~3电动铲运机,在液压系统回油管路上的一个网式滤油器,因内部损坏后,造成粘合剂破裂脱落,残渣随液压油进入油箱,又通过液压泵送往各液压元件,造成多处堵塞,清除这些残渣费了大量时间。滤油器是滤除污物,保护液压元件及系统正常工作的关键性元件。本文拟就网式滤油器及回油管路滤油器的选用问题进行论述。 “Mining Machinery” 1989 11 published a “domestic scraper problems and suggestions for improvement,” a paper pointed out that a domestic factory production 0.75m ~ 3 electric scraper, the hydraulic system in the oil return pipe network Oil filter, due to internal damage, resulting in broken adhesive off, the residue with hydraulic oil into the tank, but also through the hydraulic pump to the hydraulic components, resulting in multiple blockage, remove these residues spent a lot of time. Oil filter is to filter dirt, protect the hydraulic components and the normal work of the key components. This article intends to network oil filter and oil return pipe filter selection problems are discussed.
