《煤矿安全规程》123条第六项规定:“新安装矿井主要扇风机投产前,必须进行扇风机性能的测定……,以后每五年至少进行一次性能测定.”这就是说主扇风机性能测定应成为经常性的工作.生产矿井的主扇风机测定方式大体分为两种:停产测定和不停产测定.由于煤矿生产的连续性,停产测定的机会很少.不停产测定,对于轴流式主扇风机已有规可循,但对离心式主扇风机尚无报导.我矿一坑东大井、三坑中央风井均安装了离心式主扇风机.自安装以来从未进行过性能测定,其主要原因是由于该风峒直线长度短,不能满足风流稳定的要求,并且,要停风停产困难很大.鉴于这种情况,我们参
Article 6 of the “Coal Mine Safety Regulations” states: “The main fan of the newly installed mine must be tested for fan performance before it is put into production ... at least once every five years thereafter.” This means that the performance of the main fan Determination should be a regular work .Minery fan production method can be divided into two main ways: stop production and non-stop production determination .Because of the continuity of coal production, cut-off determination of seldom .Continuous production determination, for axial flow Main fan has been regulated, but there is no report on the centrifugal main fan.I have a centrifugal main fan installed in Dongdajing mine and Sankeng central well of mine, and have never performed any performance since installation The main reason is that due to the short straight line length of the wind, it can not meet the requirements of stable wind flow, and it is very difficult to stop the wind for stopping. In view of this situation,
