自激动力制动调速的起重机,其起升机构在运行中可能会出现各种各样的故障,如何着手检查故障进而排除呢?下面以《电世界》1994年第8期“起重机自激动力制动调速的实际电路”一文中的图1、图2典型线路为例,来介绍起重机自激动力制动调速电路的故障检查及排除方法。 1.电路的检查为了方便电路的检查,简捷的方法是在熟悉电路原理的基础上,根据电路图列出
Self-excited dynamic braking speed crane, the lifting mechanism in the operation may be a variety of failures, how to proceed with the inspection and then exclude it? In the following “Electric World” No. 8 1994 “Crane Actuator braking speed actual circuit ”a text in Figure 1, Figure 2 typical lines, for example, to introduce the crane self-excited dynamic brake speed control circuit troubleshooting and troubleshooting methods. 1. Circuit Check In order to facilitate the inspection of the circuit, a simple and easy method is based on the familiar circuit principle, according to the circuit diagram
