一、电阻制动器采用打砂清扫方法带有电阻制动装置的东风型内燃机车,在长期运行中,由于电阻制动元件受到机车油烟以及灰尘影响使电阻制动装置绝缘受到破坏,有时甚至没有绝缘,造成电阻制动不能使用。成为我段机车质量关键之一。电阻制动元件绝缘下降的原因主要是瓷管、瓷帽上固着一层油泥,且油泥渗透至瓷管、瓷帽表面的微孔中。过去我段电气组工人同志采用了许多清洗方法,如用汽油清洗,化学清洗(三氯乙烯),火碱煮洗,砂布打磨,电炉烘干都未能解决电阻制动元件的绝缘问题。电气小组工人师傅遵循伟大领袖 First, the resistance brake using sand blasting method With a resistor braking device Dongfeng diesel locomotive, in the long run, due to resistance brake components affected by locomotive fumes and dust so that the resistance braking device insulation is damaged, and sometimes not even insulated , Resulting in resistance braking can not be used. Become one of the key quality of locomotives. Resistance braking element insulation is mainly due to declining porcelain, porcelain cap fixed a layer of sludge, and oil sludge permeate porcelain, porcelain surface of the micro-holes. In the past, my colleagues in the electrical group used many cleaning methods, such as gasoline cleaning, chemical cleaning (trichlorethylene), caustic soda cleaning, emery cloth grinding, and electric furnace drying. All failed to solve the insulation resistance of the braking element. Electrical team workers follow the great leaders of the great master
