摘要
EVA-625电梯/扶梯振动和噪音分析仪是由美国PMT公司研制的一种计算机辅助检测系统。该仪器可以对电梯和扶梯的多项特性参数进行测量,如:噪音、运行距离、速度、加(减)速度、加加速度、振动等特性,以及扶梯的梯级速度与扶手带速度差、梯级与裙板的安全间隙和摩擦系数等,而且测得的数据可以保存并由计算机处理以曲线图显示,对测量得到的数据进行分析,可以发现电梯和扶梯存在的潜在问题。
EVA-625 is an elevator and escalator vibration and noise analysis system designed by American company PMT, which constituted by a set of software and some auxiliary hardware. EVA-625 can inspect a lot of elevator's and escalator's parameters, such as: noise, distance, speed, acceleration, deceleration, jerk, vibration, the distance and coefficient of sliding friction between the edge of the step and skirt, etc. All data detected by EVA-625 can be recorded and displayed in diagram of curves. We can also find some potential problems by analyze the detected data.
