电子限速器在电梯中的应用初探
|
摘要
针对目前电梯用离心式限速器棘爪不动作、可靠性差和动作响应滞后等缺点,提出了电子限速器的设想。将触发装置由离心式改为电气式,限速器轮的动作速度由离散型改为给定动作型,保证电梯运行时的稳定。设计限速器的电气控制装置,将实际速度与设定速度进行实时对比,当实际速度达到设定速度时,立即向限速器轮和电梯控制系统发送信号,及时可靠制停轿厢。
The assumption of electronic speed limiter was put forward aiming at the shortcomings of the current centrifugal speed limiter's pawl non-movement, poor reliability and action response lag. The trigger device has changed from centrifugal type to electrical type, and the speed of action of the speed limiter wheel has changed from discrete type to a given action type to ensure the stability of the elevator operation. The electrical control device of the speed limiter is designed. The actual speed will compare with the set speed in real time. When the actual speed reaches the set speed, the signal will be sent to the speed limiter wheel and elevator control system immediately, and the car will stop in a timely and reliable way.
