一台农用水泵的骨架油封内小弹簧锈蚀折断,由于手头无配件,又急着抽水,我便自制了一小胶圈套在油封弹簧槽内,装复后抽水正常。此法又在其它地方试用几次,效果良好。一些农用水泵的密封采用骨架式油封,在使用后因内部积水没排净,停放一段时间后,易造成小弹簧锈蚀折断,此时可采用以上应急修理方法。自制小橡胶圈的材料可选用平板橡胶(如畜力车、机动车的废内胎),依油封唇部小弹簧槽的横断面尺寸,用剪刀剪成一个形如垫圈的小橡胶圈。制作中选用的平板橡胶厚度最好接近弹簧槽宽度。由于橡胶的材质和弹性等难以确定。胶圈
A farm pump oil seal rust within the small spring broken, because no accessories on hand, but also hurry pumping, I then made a small rubber cover set in the spring seal tank, installed complex pumping normal. Try this method a few times in other places, the effect is good. Some agricultural pump seal with a skeleton oil seal, after use due to internal water is not clean, parked for a period of time, easy to cause small spring rust fracture, this time can be used above emergency repair methods. Self-made small rubber ring material can choose flat rubber (such as animal vehicles, motor vehicles, waste inner tube), according to the oil seal lip small spring groove cross-sectional size, scissors cut into a small rubber ring shaped like a washer. The thickness of the flat rubber used in the production is preferably close to the spring groove width. Due to the rubber material and flexibility is difficult to determine. Apron
