Description

用于防止涡轮机的叶轮-轴组件的腐蚀的方法
技术领域
本发明涉及用于防止涡轮机的叶轮-轴组件的腐蚀的方法。本发明的方法可以有利地用于防止海底或岸上或离岸涡轮机的构件中的腐蚀。在以下公开中，将特别地参照离心压缩机，以仅用于容易说明，然而不意图对本发明适用性的任何限制。
背景技术
如碳钢、低合金钢和不锈钢的材料通常当构建在海底或岸上或离岸环境中操作的构件时使用。如果此种环境包括湿的二氧化碳(CO2)和/或湿的氢化硫，则碳钢和低合金钢将受到腐蚀损伤的影响。而且，如果此种环境包括氯，则不锈钢将受到点蚀腐蚀损伤的影响。
用于防止涡轮机的叶轮-轴组件的腐蚀的方法在本领域中是已知的。实际上，涡轮机的叶轮-轴组件可由防腐蚀合金(例如不锈钢或镍合金)制成。这当涡轮机计划在腐蚀性环境中操作时进行。
发明内容
上述现有技术的缺点是其招致较大的成本，因为防腐蚀合金与低合金钢相比显著更昂贵。
本发明的第一方面因而涉及用于防止涡轮机的叶轮-轴组件的腐蚀的方法，该方法包括将叶轮组装在轴上，以便限定叶轮-轴组件的步骤。涂布叶轮上的第一预定表面和轴上的第二预定表面。在涂布步骤之后通过将组件插入镀浴中来镀敷该组件。有利地，这允许容易地喷涂或电镀当叶轮组装在轴上时难以到达的表面。
此种方法还具有允许构建用于在腐蚀性环境中使用的叶轮-轴组件而不依赖昂贵合金的优点。实际上，通过将零件插入镀浴中来涂布它们。该成分还被涂布到当组装后在间隙内侧或浴内的镀敷溶液难以到达的其他地方的表面上。因此在涂布和镀敷之间，相对于腐蚀保护整个组件，且整个组件因而可由低合金钢或碳钢制成。
在本发明的另一方面中，镀敷步骤是通过无电镀镍来执行的。有利地，如果在整个组件上执行镀敷，则当在上述方法的情况下时，在组装期间防止镀敷的弱化。如果在叶轮上和在轴上分开地执行镀敷，则将发生此种弱化，因为叶轮和轴中的一者需要被加热以用于组装步骤。
附图说明
更多细节和具体实施例将参照附图，在附图中：
- 图1是根据本发明实施例的叶轮-轴组件的示意截面侧视图；且
- 图2a、2b和2c是根据本发明实施例的用于防止叶轮-轴组件的腐蚀的方法的相应步骤的示意图。
具体实施方式
示范实施例的下列描述参照附图。不同附图中的相同参考标号标识相同或相似的元件。下列详细描述不限制本发明。相反，本发明的范围由所附权利要求限定。
贯穿说明书对“一个实施例”、或“实施例”的引用指的是与实施例结合地描述的具体特征、结构、或特性包括在所公开主题的至少一个实施例中。因此，短语“在一个实施例中”或“在实施例中”的在贯穿说明书的各种位置中的出现不一定指相同的实施例。而且，具体特征、结构、或特性可以以任何适当的方式组合在一个或更多个实施例中。
因此，将通过参照附图来描述用于防止涡轮机的叶轮-轴组件的腐蚀的方法，其中，将用数字1来参照该叶轮-轴组件。
叶轮-轴组件1包括轴3。轴基本上是圆柱形的，且具有侧表面3a。
叶轮-轴组件1还包括安装在轴3上的叶轮2。具体而言，叶轮2相对于轴3同轴。因此，叶轮-轴组件1具有中央轴线“A”，该中央轴线限定轴3和叶轮2的旋转轴线。此外，叶轮2具有内表面2a，该内表面2a在使用时面对轴3。实际上，叶轮2的内表面2a的最大部分与轴3实际上接触。叶轮2还具有相对于轴3面朝外的外表面2b。
内表面2a和外表面2b二者在化学侵蚀性环境中操作的情况下可被处理，以防止对叶轮2自身的损伤。将在本公开的以下部分中给出更多细节。
更详细地说，叶轮-轴组件1包括多个叶轮2。在两个连续的叶轮2之间，组件1包括套筒4，套筒4附接于轴3。根据图1中示出的实施例，轴3的中央轴线“A”可认为是套筒4的对称轴线。
本发明的实施例因此涉及用于防止叶轮-轴组件1腐蚀的方法。此种方法包括至少涂布所述叶轮2上的第一预定表面5的步骤。此种第一预定表面优选为内表面2a的面对轴的部分。更具体而言，叶轮2包括键槽6，键槽6用于将叶轮2自身可逆地附接于轴3。第一预定表面5因此为叶轮2内表面2a的限定键槽6的部分。
还以与第一预定表面6相同的方式涂布第二预定表面7。优选地，第二预定表面为轴3的侧表面3a的一部分。更具体而言，第二预定表面7为构造成接收键的键座8的表面，该键也插入叶轮2的键槽6中，以便将叶轮2附接于轴3。
根据本发明的所描述的实施例，涂布第一5和第二预定表面7的步骤是通过喷涂或电镀它们来执行的。在本发明的优选实施例中，利用冷喷涂来喷涂第一5和第二预定表面7。此种冷喷涂例如可包括由镍基合金、钴基合金或不锈钢制成的固体粉末。
冷喷涂通过动力学效应来作用，这意味着构成喷雾的颗粒可借助于它们的动能而将它们自身埋入预定表面5、7的层中。有利地，这避免预定表面5、7的任何不必要的热处理。
备选地，涂布预定表面5、7的步骤可通过利用热喷涂对它们进行喷涂来执行。以此方式，喷雾自身的温度也处理预定表面5、7。
备选地，涂布预定表面5、7的步骤可通过电镀来执行。电镀可例如利用电解铬或镍来执行。
如果套筒4将包括在组件1中，则涂布步骤还可包括涂布叶轮2上的第三预定表面9。此种第三预定表面9为叶轮2表面的在操作时面对套筒4的部分。
涂布步骤还可包括第四预定表面10的涂布。此种第四预定表面10也向着轴3。具体而言，第四预定表面10为轴3侧表面3a的与叶轮2和套筒4重叠的部分。
涂布步骤还可包括涂布第五预定表面11的步骤。此种第五预定表面位于套筒4上，具体而言在套筒4的面对叶轮2的表面上。换而言之，第三9和第五预定表面11面对彼此。第四预定表面10横跨在第三9和第五预定表面11之间的间隙。
第三9、第四10和第五预定表面11的涂布是以与第一5和第二预定表面7相同的方式执行的。关于上述涂布方法(冷喷涂、热喷涂或电镀)，它们可以以适用于特定目的的任何组合的形式来应用。换言之，第一5、第二7、第三9、第四10、和第五预定表面11的涂布可以都利用相同的特定涂布方法或利用它们的任何组合执行。
在涂布步骤之后，将叶轮2组装在轴3上。具体而言，通过将键(图中未示出)插入叶轮2的键槽6中来将叶轮2锁定到轴3上。该键还被置于轴3的键座8中。如果使用套筒4，则还通过将其锁定在两个叶轮2之间来在该步骤中安装其。对必须安装到轴3上的各叶轮2和套筒4重复以上操作。
根据本发明的优选实施例，然后对组件1进行镀敷。优选地，这通过将组件1插入镀浴中且通过在预定时间之后将其拔出来执行。
优选地，镀敷的步骤是通过无电镀镍来执行的。实际上，镀敷步骤包括第一沉积子步骤，其中，通过电镀将第一金属层沉积在组件1基底上。然后，执行第二沉积步骤，其中，通过无电镀敷至少将为镍合金的第二层镀敷在第一层上。然后可在沉积步骤之后执行热处理步骤。热处理的温度和持续时间取决于层的总厚度且取决于要获得的最终特性。
可选地，镀敷步骤可包括第三沉积步骤，其中，通过电镀将第三金属层沉积在第二层上。还可以可选地执行通过无电镀敷在第三层上沉积为镍合金的第四层的第四沉积步骤。
