我单位1台原装进口W1000F型路面冷铣刨机(以下简称铣创机)于10年前购置,经过多年使用后,其液压系统故障频发,返厂维修费用较高,维修周期长。为此,我们自行排查了一些故障,本文介绍一例行走异常缓慢故障的排查过程。1.故障现象故障表现为启动发动机后,铣刨机空载行走速度正常;扳动铣刨鼓转动开关,铣刨鼓空载运转
My unit 1 imported W1000F pavement cold milling machine (hereinafter referred to as milling machine) was purchased 10 years ago, after years of use, the hydraulic system failure frequently, the cost of repairing the plant is higher, the maintenance cycle is long. To this end, we have to troubleshoot some of the problems, this article describes a case of walking exceptionally slow troubleshooting process. 1. Symptom Fault performance is to start the engine, the milling machine no-load speed of normal walking; turn the milling drum rotation switch, milling drum no-load operation
