水泵外部涂层的喷涂工艺
本专利技术涉及水泵防护领域,具体涉及水泵外部涂层的喷涂工艺。
技术介绍
双吸泵作为离心泵的一种重要形式,因其具有扬程高、流量大等特点,在工程中得到广泛应用。这种泵型的叶轮实际上包括泵壳和叶轮等部件,泵壳和叶轮通常因为所需功能的不同而喷涂不同的防护涂层,由于泵壳部件经常与各种液体物质接触,特别是在输送黄河水的流域,泥砂含量及成份、形态等情况复杂多变,泵壳部件损坏率很高,因此,泵壳部件的防腐蚀处理尤其重要。
技术实现思路
针对现有技术的不足,本专利技术提供了水泵外部涂层的喷涂工艺,包括如下步骤:S1.喷砂处理:对待喷涂的泵壳部件表面进行喷砂粗化;S2.表面清洗:浸入金属清洗剂、去离子水和无水乙醇中进行超声清洗处理;S3.烘干除尘:将泵壳部件在烘干室内进行烘干,所述烘干室的温度为85-90℃,所述烘干的时间为10-15min;将泵壳部件以1~3℃/min的降温速度进行冷却降温至温度区间20-30℃,冷却后在真空环境对泵壳部件表面进行静电除尘;S4.防腐底漆:对所述干燥的泵壳部件表面进行等离子喷涂防腐底漆,所述防腐底漆厚度为0.05-0.15mm;S5 ...
