矿 井提升机其可靠性直接关系到正常生产、职工的人身安全。对线路电压突发波动现象而造成提升机危害应有所防范 ,本文以GKT2×2×1.25-12.5提升机为例 ,探讨电压波动危害和防范措施。1制动原理制动系统由液压站、盘式制动器和油路组成。液压站主要含电动机、叶片泵、电磁换向
Mine hoist its reliability is directly related to normal production, personal safety of workers. On the sudden fluctuations of line voltage caused by the hoist damage should be prevented, this article to GKT2 × 2 × 1.25-12.5 hoist as an example to explore the hazards of voltage fluctuations and preventive measures. 1 brake principle Braking system consists of hydraulic station, disc brakes and oil composition. Hydraulic station contains the main motor, vane pump, electromagnetic commutation
