在BTS60-13-90型拖式混凝土泵使用过程中,其电控系统会出现一些故障。本文结合该型拖式混凝土泵电控系统原理图,对5起电控系统故障进行分析和排查。该型拖式混凝土泵电控原理如附图所示。1.泵送工作突然停止(1)故障现象主电动机M能够正常运转,但是当操纵混凝土泵进行自动泵送作业时,泵送液压缸突然停止泵送,使用遥控盒和控制柜均不能重新启动泵送液压缸。(2)原因分析经分析,造成该故障的原因有以下6点:
In the use of BTS60-13-90 type towed concrete pump, the electrical control system will be some failure. In this paper, the type of trailing concrete pump schematic diagram of electronic control system, five electronic control system failure analysis and troubleshooting. This type of trailing concrete pump electric control principle as shown in the figure. 1. Sudden stop of pumping (1) Symptom Main motor M can operate normally. However, when the concrete pump is operated for automatic pumping, the pumping cylinder suddenly stops pumping, and neither the remote control box nor the control cabinet can be restarted Pump hydraulic cylinder. (2) Analysis of the causes of the analysis, the cause of the failure has the following 6 points:
