防爆液压提升绞车在煤矿有广泛应用,但由于井下工作环境恶劣、工况复杂多变,绞车液压系统工作可靠性和稳定性成为制约液压提升绞车正常工作的瓶颈问题,且液压系统故障隐蔽性强,极难直观判断。本文在详细分析液压提升绞车各种工况的基础上,研究开发了防爆液压绞车状态监测系统,并对其关键技术问题作了详细分析。
Explosion-proof hydraulic winch has been widely used in coal mines. However, due to the poor working environment and complicated conditions, the reliability and stability of the winch hydraulic system become the bottleneck restricting the normal operation of hydraulic winch. Very difficult to judge intuitively. Based on the detailed analysis of various working conditions of hydraulic lifting winch, this paper researched and developed the condition monitoring system of explosion-proof hydraulic winch and analyzed its key technical problems in detail.
