摘要
电动风门的功能是利用QC83-80N可逆磁力起动器的可逆性,来控制风门起闭绞车电机的正反转,从而,使绞车缠绳或放绳,再通过传动滑轮组来打开或关闭风门;其结构简单、操作方便、开关灵活、开闭安全、省时省力、生产效率高。
The electrically operated air throttle function is uses the QC83 - 80N reversible magnetic starter the invertibility, controls the air throttle to get up shuts the winch electrical machinery the reverse, thus,causes the winch to entangle the rope or to put the rope, again turns on or closes the air throttle through the transmission slipping group;Its structure simple, the ease of operation, the switch nimble, the make and break safe, time - saving reduces effort, the production efficiency is high.
