HYY02/2T双级叶片泵的网式滤油器,原由18片金属网和两组永久磁铁构成(图1),这种滤油器使用两年就得更换一次,拆装比较麻烦。为此,我们采用120目铜网自制了一种直筒式滤油器(图2)。改进后的滤器取消了永久磁铁,结构又简单易制,成本低廉,过滤精度可在5微米以内,满足叶片泵的滤油要求。经使用5年,未发现任何异常现象,值得推广。 HYY02 / 2T two-stage vane pump mesh filter, originally composed of 18 metal mesh and two sets of permanent magnets (Figure 1), this filter has to be replaced after two years, disassembly is too much trouble. To this end, we use a 120 mesh copper net made of a straight-type filter (Figure 2). The improved filter cancels the permanent magnet, the structure is simple and easy to manufacture, the cost is low, the filtration precision can be less than 5 microns, and the vane pump oil filter requirements can be met. After five years of use, no abnormalities were found and it deserved promotion.
