矿井自动排水与变频调速

Automatic Drainage and Conversion Speed Governing in Colliery

根据煤矿井下水泵的工作特点,从水泵特性、井下水泵出水口压力、井下水泵设备容量、井下水泵起动特性和排水可靠性等几个角度阐述了把变频调速技术应用于井下自动化排水系统的局限性,总结了在矿井自动化排水设计中应用变频调速时的条件,为合理确定矿井自动化排水的设计方案提供了理论依据。

Automatic drainage is one of the important parts of the crating characteristics of the underground water pump, sets forth sion speed governing used in the automatic automation of collieries. According to the opsome limitations of the technology of converdrainage system underground the feature, the pressure of the delivery port, the capacity, the starting the underground water pump. It summarizes the conditions when using , from several points of view, such as feature and the drainage reliability of conversion speed governing in the designing of the automatic drainage system, providing some theoretical basis on the proper design of the automatic drainage system of collieries.
