矿山排水设备选型设计及主要零部件的结构设计
摘要:本课题的主要内容是矿山排水设备的选型设计及压水室形状对水泵性能的影响。在此课题的设计过程中,主要运用分析、比较等方法,根据矿井安全生产的政策,法规,应用历史设计经验,结合煤炭行业发展现状,以安全可靠为根本,以投入少、运行费用低为原则的设计指导思想来进行综合设计的。
本课题来源与工程实际,因此在设计的过程中,通过多种渠道掌握给排水行业最新信息,初步选择排水方案并对设备选型,进行相关计算,确定设备工况,然后通过校验水泵的吸水高度、排水时间,以及对各方案水泵装置效率的比较,排除不合理的方案,最后再对方案进行经济核算以确定方案的合理性。
有关压水室的专题方面的讨论,进一步优化了水泵的整体结构设计。

Mine Drainage Equipment Selection and Design
of The Main Parts of The Structure Design
Abstract: The issue is the major content of the mine drainage equipment selection and design of the pressurized water Room shape on the performance of pumps.
In this issue of the design process, the main use of analysis, comparison, According to the mine production safety policies, regulations, application design experience history, the coal industry with the current state of development Safe and reliable as the fundamental, less investment and operating costs low for the design principles guiding ideology for the integrated design.
The issue with the engineering source, So in the design process, through various channels to grasp the latest information and drainage industry, Initial drainage programs to choose equipment selection, calculations to determine the status of equipment, Then check the suction pumps height, drainage, and the right of the programs the pump device efficiency, exclude unreasonable proposal, the program further economic accounting to determine the reasonableness of the program.
The pressurized water Room of the topics discussed, and further optimize the overall structure of the pump design.
Keywords:Drainage System;Pumps; Working conditions; PWR Room
