目前农村使用水泵为数很多,在运轉过程中蝸輪叶承磨环損耗最大,叶片亦常被損坏至不能使用。如經采用环氧树脂修补及涂复后,即可恢复其使用寿命,效果良好。現将我們的經驗簡介如下,以供参考。一、蝸輪叶表面涂复工艺(1) 环氧树脂涂料配方(重量比): 环氧树脂①100;邻苯二甲酸二丁酯20;乙二胺5;水泥20。(2) 环氧树脂涂料調制法: 按份量在瓷质容器中加入环氧树脂和邻苯二甲酸二丁酯,用玻璃棒充分攪拌均勻,然后徐徐加入乙二胺,再次充分攪勻,最后加入水泥,彻底攪勻备用。(3) 涂复工艺: 1.蝸輪叶表面处理:可用机械法(鋼絲刷、噴砂、
At present, there are many pumps in rural areas. During operation, the wear of worm gear leaves is the largest, and the blades are often damaged and can not be used. If the use of epoxy resin repair and coating, you can restore its service life, the effect is good. Now our experience is as follows for reference. First, the worm gear surface coating process (1) Epoxy resin coating formulations (weight ratio): Epoxy ① 100; dibutyl phthalate 20; ethylene diamine 5; (2) Epoxy resin coating preparation method: according to the weight of the porcelain container by adding epoxy resin and dibutyl phthalate, with a glass rod stir, and then slowly add ethylenediamine, stir again, and finally Add cement and mix thoroughly. (3) coating process: 1 worm wheel surface treatment: available mechanical method (wire brush, sandblasting,
