一、起动困难１、柴油机机件磨损超限或电动机的输入电压过低。排除方法是检修柴油机 ,更换损坏件。由电压过低引起的要认真检修线路 ,将小线号换成较大规格线号。２、起动前未加预润水或加水不足 ,橡胶轴承和轴间隙小 ,泵轴弯曲轴和轴承相互摩擦或卡住。此时应拆泵逐级检修 , First, the starting difficulty 1, wear and tear of diesel engine parts or motor input voltage is too low. Exclusion method is to repair the diesel engine, replace the damaged parts.
