一种液压油分级滤油装置

Abstract

本实用新型涉及液压油滤油设备技术领域，具体的是一种液压油分级滤油装置，本实用新型包括底部设有自锁轮的移动仓，所述移动仓的顶部固定安装有精过滤器和粗过滤器，移动仓的内部固定连接有容纳箱，精过滤器的出油口固定连接有输送管道，输送管道的底部延伸至容纳箱内；移动仓内部设置有排油机构，本实用新型通过设置容纳箱，对液压油滤油后起到临时保存的作用，保证液压油的平稳输出，还能在储液桶装满滤油后的液压油时，关闭油泵，液压油保存在容纳箱内部，待更换储液桶后，再将液压油从容纳箱中输入到储液桶中，使得无需停止滤油，即可对储液桶进行更换，保证液压油滤油的连续性，提升滤油效率。

Claims
