ZZD-55直流钻井电动机和JZK,JZC可控硅电控设备系AT500型电动天井钻机用驱动电机和电控装置。AT 500型井下天井钻机是我国第一台电动天井钻机,它的研制成功,为我国在天井钻机上采用直流电机驱动,可控硅调速迈开了第一步,亦是在天井钻机中使用电动系统初次尝试。成功地解决了矿山凿岩、钻井的生产关键,改善了井下作业的条件。ZZD-55电机和JZK,JZC电控设备经广东南山钨矿使用后证明该机采用直流电机直接驱动,由三相可控硅整流系统供电,实现从零到额定转速下无级调速,能适用于各种岩层的钻进工作,电气
ZZD-55 DC drilling motors and JZK, JZC SCR electronic control equipment AT500-type electric patio rig drive motor and electric control device. AT 500 downhole drilling rig is China’s first electric patio rig, its successful development, for our country in the drilling rig on the use of DC motor drive, SCR speed took the first step is also used in the patio rig Electric system first attempt. Successfully solved the mine rock drilling, drilling the key to improving the conditions for downhole operations. ZZD-55 motor and JZK, JZC electronic control equipment after the use of Guangdong Nanshan tungsten ore proved that the machine is directly driven by a DC motor, controlled by a three-phase thyristor rectifier system to achieve from zero to rated speed stepless speed regulation, energy For a variety of rock drilling work, electrical
