丰收—35、37拖拉机液压油泵阀体上的顶塞用卡簧(即弹性挡圈)固定于孔内,如安装时卡入槽内过浅、卡簧变形或操作使用不当等原因,会使卡簧从槽中脱出,顶塞则被油压冲出,破坏了液压系统的工作,甚至造成事故。为此,上海—50拖拉机上的顶塞改成螺塞的形式。许多使用维修单位也采取了一些预防措施。现将广东番禺农机修造厂等单位采用的一种方案介绍给大家参考。如图示,仿照卡簧安装后的内径形状和大小做一块铁板(可用外径19毫
Good harvest -35,37 tractor hydraulic pump valve body top plug with spring (ie, retaining ring) is fixed in the hole, such as installation card slot too shallow, the spring deformation or improper operation and other reasons, will So that the card spring from the tank projectile, the top plug is hydraulic out, undermining the hydraulic system work, and even cause an accident. To this end, Shanghai -50 tractor top plug into the form of plug. Many service providers have also taken some precautions. Now Guangdong Panyu Agricultural Machinery Factory and other units used to introduce a program for your reference. As shown in the picture, follow the shape and size of the inner diameter of the retainer to make an iron plate
