煤矿支架液压液的选择和使用

Selection and Application of Coalmine Support Hydraulic Fluids

液压支架是井下采煤作业的重要机械设备。支架液压液包括乳化油、浓缩液及其高含水液压液,是液压支架的"血液",起着能量传递和转换的作用。支架液压液规格多,每一种规格的支架液压液对水质有严格的要求。同时,为确保安全,支架液压液还必须取得安全认证。介绍了支架液压液的规格,命名和选用原则,分析和解答了支架液压液在使用过程中的常见问题。

The hydraulic supports are an important mechanical equipment of underground coal mining opera- tions. Support hydraulic liquids including emulsified oils, concentrates and their high water content hydraulic flu- ids are the ＂blood＂ of hydraulic supports which play the roles of energy transfer and conversion. Support hydraulic fluids have specifications, every specification of the support hydraulic fluid has strict requirements on water quali- ty. Support hydraulic fluids must be obtained security certification to ensure safety in addition. The specifications, naming and selecting principles of support hydraulic fluids were introduced, and the common problems in the course of application of support hydraulic fluids were analyzed and answered.
