失速性能的现场检测

液力传动工程机械的整机出力不足时,要判明其原因是发动机输出功率不足,还是传动系有故障,这是现场经常遇到的一个问题。本文介绍的本机现场失速性能测定法,使用一只光电转速表即可评定原机稳定工况下的发动机功率,是一种判断机械出力不足故障原因的有效方法.

Measurement of Runaway Performance in Operational Field

It is a question often met in operational field to judge the reasons of tractive power lack in a construction machinery with hydrodynamic transmission system,which way be caused by the unsufficient power output of engine or by the trouble in transmission.This paper has introduced a measurement method of runaway performance in operational field by using an optoelectionic speed meter to evaluate the engine power in stable condition.It is an ef- ficient method to judge the reasons of power lack.
