3三对磨擦副检查与修复
3.1柱塞杆与缸体孔表1为柱塞泵零件的更换标准(参见图1),当表中所列的各种间隙超差时,可按下述方法修复:(1)缸体镶装铜套的,可以采用更换铜套的方法修复。把一组柱塞杆处径修整到统一尺寸,再用1000#以上的砂纸抛光外径。缸体安装铜套的三种方法:
(a)缸体加温热装或铜套低温冷冻挤压,过盈装配。(b)采有乐泰胶粘着装配,这咱方法要求铜外套外径表面有沟槽。(c)缸孔攻丝,铜套外径加工螺纹,涂乐泰胶后,旋入装配。(2)熔烧结合方式的缸体与铜套,修复方法如下。(a)采用研磨棒,手工或机械方法研磨修复缸孔。(b)采用座标镗床,重新镗缸体孔。(c)采用铰刀修复缸体孔。(3)采用“表面工程技术”,方法如下:(a)电镀技术:在柱塞表面镀一层硬铬。(b)电刷镀技术:在柱塞表面刷镀耐磨材料。(c)热喷涂或电弧喷涂或电喷涂:喷涂高碳马氏体耐磨材料。(d)激光熔敷:在柱塞表面熔敷高硬度耐磨合金粉末。
