Ｈ １ 泵是本公司黄河取水的关键设备，为解决黄河水泥沙对Ｈ １ 泵碳钢叶轮气蚀磨损严重的问题，我们采用了等离子热喷涂技术和钨钴硬质合金粉末，在叶轮表面喷涂耐蚀耐磨涂层。经试用，可延长叶轮使用寿命４ 倍以上，节约了备件和检修费用。
H 1 pump is the key equipment for the Yellow River water intake of the Company. In order to solve the serious problem of cavitation erosion of the H 1 pump carbon steel impeller due to the Yellow River cement sand, we adopted the plasma thermal spraying technology and the tungsten-cobalt cemented carbide powder. Coating corrosion and wear-resistant coating. After trial, can extend the service life of impeller 4 times, saving spare parts and maintenance costs.
