泵站水力机械抗气蚀耐磨损工艺研究

在多泥沙（黄河水源）抽水站水力机械使用过程中，除正常的泥砂和机械磨损外，其过流断面以及本体受气蚀的危害，严重影响水力机械运行工况，提高了能源单耗。经过多年的实践，在水力机械过流部件上涂耐磨材料，可以大大提高水力机械使用寿命，降低运行成本。

Process Research on Gas-ecthing-proof & Anti-brasion of Hydraulic Machinery for Pump Station

When a pump station is built for sandy water(from Yellow River),during the operation of hydraulic machinery,except the normal abrasion by sand and mechanical wearing,the cross section and the main body are damaged by gas etching,which is heavily impacted the operation capability,increasing unit cost of energy.In the text,the author presents the results through many years' practice and study,i.e.after the cross section of main parts of hydraulic machinery is coated with anti-abrassive material,the operation ...
