DY—150型采煤机电控部分在运行中一般比较可靠。但由于震动及操作、使用不当等原因,不可避免地要发生一些故障。电气故障可分为二大类。一类为馈电开关方面的故障,另一类为载波机的故障(占电气故障的80％以上)。处理电气故障时,首先要了解使用情况,搞清楚是在停机时还是在运行中发生的故障,从容易发生故障的部位入手,逐步深入进行测试。排除故障的顺序大致是:
DY-150 Shearer electric control part of the operation is generally more reliable. However, due to vibration and operation, improper use and other reasons, some failures will inevitably occur. Electrical faults can be divided into two categories. One for the feed switch failure, and the other for the carrier fault (accounting for more than 80% of electrical faults). When dealing with electrical faults, we must first understand the use of the situation, figure out when the machine is down or in operation in the event of failure, starting from the prone parts, and gradually in-depth testing. The order of troubleshooting is roughly:
