水冶过程需要输送和控制腐蚀性化学试剂和磨蚀性物质,它们通常呈泥浆状存在于溶液之中。如果使用得当,泵的选型在这种情况下是关键因素。转速高的泵,其合金部分会受到冲击性腐蚀,如果液料中含固体颗粒,这种腐蚀作用更加严重。因此,在水冶过程中泵的设计、选型和材质的选择是同等重要的。由于腐蚀和转速的联合作用而使泵体金属和合金急速损坏的现象被称为磨蚀-腐蚀
The hydrometallurgical process entails transporting and controlling corrosive chemicals and abrasive substances, which are usually slurried in solution. If used properly, the selection of the pump is the key factor in this case. High speed pumps, the alloy part of the impact corrosion will be affected, if the liquid material containing solid particles, the corrosion is more serious. Therefore, in the process of watermelon pump design, selection and material selection is equally important. The rapid destruction of pump body metals and alloys due to the combination of corrosion and speed is known as erosion-corrosion
