E512发动机上的机油粗清器芯为纸质,这种滤芯过滤效果差,而且使用寿命也短.为使其达到良好的过滤效果,我们改用东方红——75拖拉机上的粗滤芯.其改制方法是:将粗滤芯的内波纹筒下方的孔加大,修出一个平面,使之能和粗滤器应(E512)上的定位管能紧密配合,并加一个毡垫,以保证其密封性.在外波纹简的上方也把孔加大,修出一个平面,以保证和原粗滤器(E512)上的限压阀贴合好,然后再在内、外波纹筒的顶部加一道密封毡圈,待这些工序做
E512 engine oil rough cleaner core paper, the filter effect is poor, and the service life is short. In order to achieve good filtration, we use the East Red - 75 tractor coarse filter. The restructuring method is: the coarse filter within the corrugated tube under the hole to increase, repair a plane, so that the strainer should be (E512) on the positioning tube can be closely matched, and add a felt pad to ensure that the seal In the top of the outer corrugation is also the hole to enlarge, repair a plane, and to ensure that the original strainer (E512) on the pressure-limiting valve fitted, and then again, the top of the outer corrugated tube plus a sealing felt Circle, to be done by these processes
