一、前言随着能源工业的发展,矿藏开采深度逐渐增加,矿井排水所需的潜水电泵功率不断增大。我厂在借鉴国内外先进技术的基础上设计生产了大型潜水电泵机组。已有三台机组用于郑州市新中煤矿复矿排水,仅一个多月时间,完成340万米~3排水任务,为该矿恢复生产创造了条件,深受该矿好评。 I. Introduction With the development of the energy industry, the depth of mineral exploration is gradually increasing, and the power of submersible pumps required for mine drainage is continuously increasing. I plant in the advanced technology at home and abroad based on the design and production of large submersible pump unit. Three units have been used for reclaimed water drainage at Xinzhong Coal Mine in Zhengzhou City. In just over a month, 3.4 million to 3 drainage tasks were completed, creating the conditions for the mine to resume production and received favorable comments from the mine.
