鹤岗矿务局兴安煤矿的新井提人双层3t普通罐笼的提升设备,系采用洛阳矿山机器厂制造的JKM—2.25×4B型多绳摩擦轮提升机,该提升机原来的JKMK/J系统的电气制动是动力制动装置,为磁放大器——电机放大机——直流发电机系统。该系统经我矿改造为低频制动装置,这一装置为磁放大器——变频机——低频发电机系统。此外还加装了用功率方向继电器作测量元件、用步进选择器作执行元件的负荷测量装置,使该控制系统更趋于完善。这套改造了的JKMK/J电控系统自1978年投入运行以来已有6年,情况基本良好。在这几年中这一控制系统又进行了几项改进,现将
Xingang Mine, Xingang Mine, Hohhot Mining Company raised the double catenary 3t cage ordinary lifting equipment, the Department of Luoyang Mining Machinery Factory JKM-2.25 × 4B-type multi-rope friction wheel elevator, the hoist original JKMK / J system The electrical brake is a dynamic brake device for the magnetic amplifier - motor amplifier - DC generator system. The system was transformed by mine into a low-frequency brake device, this device is a magnetic amplifier - inverter - low-frequency generator system. In addition, the installation of power direction relays for measuring components, stepper selector for the implementation of load measurement devices, so that the control system tends to improve. The modified JKMK / J electronic control system has been in operation for six years since it was put into operation in 1978, and the situation is basically good. Several improvements have been made to this control system in the past few years, and will now be implemented
