高压乳化液泄漏是支架液压系统的主要故障,具有多发性、不确定性和隐蔽性的特点。乳化液泄漏时将产生连续的超声波信号,在此基础上研制成功了支架液压系统泄漏故障检测仪,并确定了相应的判据。现场应用实践表明,该仪器能迅速准确的判断支架液压系统的泄漏部位及程度,有效提高支护质量,保障工作面的安全生产。 High pressure emulsion leakage is the main fault hydraulic system stent, with multiple, uncertainty and hidden characteristics. When the emulsion leakage will produce a continuous ultrasonic signal, based on the successful development of the stent hydraulic system leakage fault detector, and determine the corresponding criteria. The field application shows that the instrument can quickly and accurately determine the leakage location and extent of the stent hydraulic system, effectively improve the support quality, and ensure the safe production of the working face.
