综采液压支架片阀及管路泄漏、串液是造成支架初撑力不足，综采工作面生产能力不能充分发挥的主要原因之一，准确判定和诊断液压支架本身泄漏故障及乳化液泵站效率，是提高综采面开机率，实现高产、高效的必要条件之一。针对目前液压支架泄漏主要原因进行探索，确立反映液压支架片阀及管路泄漏特征参量，经实验加以确认，并研制ＫＢＦ２型液压泄漏检测仪，配合ＫＪＨ４型矿压监测装置及ＢＧＣ型乳化液泵站故障测定仪，对综采液压系统进行工况监测，以提高对综采液压系统故障的确诊率
It is one of the main reasons that the fully mechanized coal mining production line can not give full play to the initial support force of the support, and the leakage and stringing of fully mechanized hydraulic support valve can accurately determine and diagnose the leakage of the hydraulic support itself and the failure of the emulsion pump station Efficiency is one of the necessary conditions to increase the turn-on rate of fully mechanized mining face and achieve high productivity and high efficiency. Aiming at the main reason of hydraulic support leakage at present, the characteristic parameters reflecting the valve and pipeline leakage of hydraulic support were established and verified by experiments. The KBF2 hydraulic leakage detector was developed and cooperated with KJH4 pressure monitoring device and BGC emulsion pump Station fault detector, the comprehensive mining hydraulic system for condition monitoring to improve the diagnosis of hydraulic system fault rate
