l 引言 在电机及其配套机组的实际生产与维修中,为了检查与评定机组安装配合的水平,往往需要实际测定电机运行断电后的滑行时间,以此来衡量机组及所带负载的整体动态装配及自身机械磨损的程度,从而来评定其是否能达到标准所规定的要求。在潜入式电泵机组测量中滑行时间测量是一项重要内容。以往对于滑行时间的测量采用断电以后,手计秒表的方式,它所产生的时间误差往往会很大,并且它所产生的人为误差常常不可确定。
l Introduction In actual production and maintenance of motors and their associated units, in order to check and assess the level of installation and assembly of units, it is often necessary to actually measure the taxi time after the motor is powered off to measure the overall dynamics of the unit and the load it carries Assembly and the extent of their own mechanical wear, in order to assess whether it can meet the standards set by the requirements. Sliding time measurement in submersible pump unit measurement is an important part. In the past, the measurement of taxi time adopted the method of hand stopwatch after the power was cut off, the time error generated by it would tend to be very large, and the human errors it produced were often uncertain.
