目前很多摊铺机工作装置熨平板采用电加热方式,其所用电能由发电机提供。发电机在工作过程中需保持转速平稳,方可保证其安全、可靠运行。本文介绍某摊铺机熨平板电加热发电机超速原因及改进措施。1.故障现象某型摊铺机在厂内调试过程中,其发电机在启动及停止瞬间经常发生超速运转现象,最高转速超过4000r/min。该发电机平稳运转时的额定转速应为3000±120 r/min,最高转速不能超过3600r/min,发电机超速会对其安全运
At present, many paver working device screed using electric heating, the power used by the generator. Generator in the work process need to maintain a stable speed, to ensure its safe and reliable operation. This article describes the reasons for the over-speeding of a paver screed electric heating generator and the improvement measures. 1. Symptom In the process of commissioning a certain type of paver, its generator often runs at an overspeed during starting and stopping, and its maximum speed exceeds 4000r / min. The rated speed of the generator should be 3000 ± 120 r / min during steady running and the maximum speed can not exceed 3600 r / min.
