Probing into dynamic braking method for mine hoist 矿用提升机动力制动方法探讨
Starting from the development of the chinese railway transportation and its requirement for the locomotive traction performance , the paper analyzed the main parameters of the locomotive such as locomotive horsepower , speed , traction effort , braking force . the traction and dynamic brake calculation of the locomotive has been made here 论文从中国铁路运输的发展对机车的牵引要求入手,对机车功率、速度、牵引力、制动力等主要参数进行了分析论证,进行了机车牵引及制动计算,并分析了机车的起动及加速性能。
Automatic control : the machine is programmable to run subject to the technique requirements and controlled by a set of equipment like plc , touch - screen monitor , frequency converter , dynamic braking , air - powered or hydraulic system programs are modifiable with individualized interface 自动化人机界面控制:通过plc ,触摸屏、变频器控制、能耗制动、气动或液动系统,机器可按工艺要求设计相应的工作程序,并按所设定的程序自动运行,采用先进的应用程序,可以更方便的修改程序。
Dynamic braking is the use of the electric traction motors of a vehicle as generators when slowing. It is termed rheostatic if the generated electrical power is dissipated as heat in brake grid resistors, and regenerative if the power is returned to the supply line.
