新安装电动机的试运与维护

New installation motors commission and maintenance

工程机电设备安装施工完成之后,通常要对电动机及其所带的机械作单机启动调试。调试运行的目的是考验设备设计、制造和安装调试的质量,验证设备连续工作的可靠性。在实际工作中往往会碰到意想不到的异常现象,使电机跳闸。为了便于事后分析,在电动机启动之前,我们就应做好事前准备工作,对一次、二次回路接线、保护回路、电动机及机械装置等进行检查,并对检查的结果加以分析。本文着重介绍电动机试运时的检查项目,并分析其常见的故障和日常维护。

Engineering mechanical and electrical equipment installation and construction is complete, usually brought on the motor and its mechanical as stand - alone start debugging. The purpose of commissioning is to test equipment design, manufacture and installation of quality, reliability of authentication devices continuously. In practice often encounter unexpected anomalies, the motor trip. In order to facilitate later analysis, motor starting, we should make advance preparations for the primary and secondary circuit wiring, circuit protection, mo- tors and mechanical devices to check, and check the results to be analyzed. This article focuses on the motor when the trial run the checks, and to analyze the common faults and routine maintenance.
