交流拖动多绳摩擦轮提升机的起动电阻计算中,无论用静阻力作为上限切换力,还是用矿机专业提供的防滑极限加速度作依据求取上限切换力,都不需要再考虑安全系数。这样既能满足防滑要求,又能提高经济效益,充分发挥电动机的能力。本文着重探讨这个问题,叙述于下。多绳提升中,钢绳与摩擦衬垫之间除产生正常蠕动外,还可能产生非正常滑动。因此,其电控系统除满足一般提升机的要求外,还应满足:①深度指示器的功能除指示深度、限速和发送信号外,还应能自动调
In the calculation of the starting resistance of AC drag multi-rope friction wheel hoist, the safety factor need not be considered no matter whether the static resistance is used as the upper limit switching force or the non-slip limit acceleration provided by the mine professional as the basis for obtaining the upper limit switching force. This will not only meet the requirements of non-slip, but also improve economic efficiency, give full play to the ability of the motor. This article focuses on this issue, described in the next. In multi-rope hoisting, besides the normal peristalsis between the steel cord and the friction lining, abnormal sliding may also occur. Therefore, in addition to its electronic control system to meet the general requirements of the hoist, but also meet: ① depth indicator in addition to indicating the depth, speed and signal transmission, but also should be able to automatically adjust
