煤矿

This paper mainly studies effect and influence factor that typical corrosive medium (muriatic acid, vitriol, nitric acid, sodium hydroxide, sodium chloride etc.), consistence and condition temperature acts on the material coated on castiron centrifugal interface (PFEP, PPS, CPE, remodeled epoxy). It is studied that powder electrostatic spray, suspend fluid spray, suspend fluid electrophoresis underside coat etc. technics influences on coat quality coated with above four anticorrosive material. The property analysis is done that above four anticorrosive material and three coat technics adapt to centrifugal pump frame and running dynamic condition. In addition, the effect is introduced that castiron centrifugal coated anticorrosive material is used in coal water with alum.

本文侧重研究了典型腐蚀工作介质盐酸、硫酸、硝酸、氢氧化钠碱、氯化钠盐等品种、浓度、环境温度，对铸铁离心泵过流面的聚全氟乙丙烯、改性聚苯硫醚、改性氯化聚醚、改性环氧四种防腐涂层材料的试验使用效果和影响因素分析；研究了四种涂层材料粉末静电喷涂、悬浮液喷涂、悬浮液电泳底涂等涂装方法工艺对涂层质量的影响；四种涂层材料和三种涂装方法对离心泵结构和运行动态环境的适应性分析；介绍了铸铁离心泵防腐涂层在煤矿矾水中的应用效果。

The drainage system is one of the most power expenditure systems in the produce of the coal mine. If the drainage system is controlled effectively, and it becomes a high-performance, low-power dissipation, oecumenical, reliable system, it will economize the cost of the produce of the coal mine effectively.

排水系统是煤矿生产的耗电大户，如果有效地控制排水系统，使其高效低耗、经济可靠地运行，也是降低煤炭生产成本的有效途径。
