农用水泵的零件表面磨损或穿孔,以前常用更换零件或机械加工法解决,成本高,也不方便。采用粘结法修理,成本低,加工工艺简单,质量可靠,深受排灌机械司机手欢迎。粘结方法如下: 1.粘结零件的表面处理:方法有手工打磨或气体喷沙。对于不便打磨和喷沙的内部工位可用毛刷蘸浓度为25—35％的硫酸液进行除锈。除锈后用清水洗,并用丙酮擦洗,使水全部挥发。处理标准应无锈斑、油水和污物,保持金属本色的粗糙状态。
Parts of agricultural pump surface wear or perforated, previously used to replace the parts or mechanical processing solution, the high cost, it is not convenient. The use of bonding repair, low cost, simple processing technology, reliable quality, welcomed by the drivers of irrigation and drainage machinery. Bonding methods are as follows: 1. Bonded parts of the surface treatment: the method of manual grinding or gas sandblasting. For inconvenient grinding and sandblasting internal working station brush dipped in a concentration of 25-35% sulfuric acid for rust. Rust wash with water and scrub with acetone to make the water completely volatile. Processing standards should be no rust, oil and dirt, to maintain the true state of the metal rough.
