浅析列车自动清洗机端洗仿形刷洗

Analysis of the end of automatic cleaning machine

仿形刷洗是列车自动清洗机的核心部分,关系到电客车端面的清洗效果。文章介绍了成都地铁两种不同的列车自动清洗机仿形刷洗的原理。一种是通过刷毛与车体端面接触的压力传感器反馈的电流信号时时调整电机运行速度,从而形成端洗仿形曲线。另外一种是通过预先计算出电客车端面仿形曲线,设定好变频器参数。从而控制电机运行速度从而形成仿形曲线。通过对比两种仿形原理,及雨刷器的防护措施,可以使以后地铁的洗车工作更加安全快捷。

Imitation brush washing is the core part of automatic train washer,which is related to the cleaning effect of electric bus.This paper introduces the principle of two different automatic cleaning machines in Chengdu Metro.One is that the current signal feedback by the pressure sensor in contact with the end surface of the car body adjusts the motor operation speed from time to time to form the end washing imitation curve.The other is to calculate the imitation curve of the electric bus and set the converter parameters.Thus control the motor operation speed to form a imitation curve.By comparing the two imitation principles,and the protective measures of the wiper,you can make the future subway car washing work more safe and faster.
