Abstract

本实用新型是一种热泵热水机的不锈钢水箱内胆,包括不锈钢内胆基体(1),其特征在于所述不锈钢内胆基体(1)的内表面覆盖有酸洗钝化层(2)。本实用新型由于采用在不锈钢内胆基体的内表面覆盖有酸洗钝化层的结构,因此,大大提高了不锈钢内胆的耐腐蚀性能,避免不锈钢水箱内胆因腐蚀穿孔破裂。

Description

一种热泵热水机的不锈钢水箱内胆
技术领域
本实用新型涉及一种热泵热水机的不锈钢水箱内胆,属于热泵热水机的不锈钢水箱内胆的改进技术。
背景技术
现有的热泵热水机,由于其不锈钢水箱内胆的内表面长时间与60~70℃热水接触,因此容易形成点蚀、孔蚀;而且不锈钢水箱内胆在加工过程,如切削、成形、组装、焊接等都会影响不锈钢内胆的表面质量,破坏表面的钝化膜,降低不锈钢内胆的耐腐蚀性能,甚至会导致不锈钢内胆因腐蚀穿孔破裂。
发明内容
本实用新型的目的在于考虑上述问题而提供一种耐腐蚀的热泵热水机的不锈钢水箱内胆。
本实用新型的技术方案是:一种热泵热水机的不锈钢内胆,包括不锈钢内胆基体,其特征在于所述不锈钢内胆基体的内表面覆盖有酸洗钝化层。
本实用新型由于采用在不锈钢内胆基体的内表面覆盖有酸洗钝化层的结构,因此,大大提高了不锈钢内胆的耐腐蚀性能,避免不锈钢水箱内胆因腐蚀穿孔破裂。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示,本实用新型热泵热水机的不锈钢内胆,包括不锈钢内胆基体1,所述不锈钢内胆基体1的内表面覆盖有酸洗钝化层2。
本实施例中,不锈钢水箱内胆焊接成型后,采用浸泡方式对内壁进行酸洗钝化处理,工艺流程为:脱脂-酸洗-钝化-清洗-水分干燥,通过上述工艺流程,使不锈钢内胆基体1的内表面覆盖一层有酸洗钝化层2。
