新型矿用水-乙二醇型难燃液压液在煤矿中的应用

Application of new mineral water-ethyleneglycol fire-resistant hydraulic fluid in coal mine

研制出的新型矿用水-乙二醇难燃液压液产品具有较高的粘度指数及润滑性能,主要性能指标与46号液压油相当,达到国外同类产品水平,并在煤矿井下液压锚杆钻机上进行了应用。使用过程中,设备运转正常,工况平稳,无锈蚀、泄露、堵塞情况。使用前后的检测数据表明:新型矿用水-乙二醇难燃液性能稳定。应用结果表明:新型矿用水-乙二醇型难燃液压液能够满足煤矿液压锚杆钻机设备的要求,可以替代46号液压油用于煤矿井下。

Introduce the excellent viscosity index（VI） and lubricity of one kind of new mineral water-ethyleneglycol fire-resistant hydraulic fluid.Its main performance indexs are the same as those of No.46 hydraulic oil,and are fully comparable with foreign similar products.Analyze the application of this hydraulic fluid in roof bolter in the pit.The detection datas show that the equipment has been running smoothly,meanwhile,no leakage,corrosion and blockage conditions.These evidence indicates that this hydraulic fluid meets the requirements of roof bolter and would replace No.46 hydraulic oil.
