柴油发电机组在使用过程中常见错误操作

作者:康明斯发电机厂家 发布日期:2016-08-17 来源:www.0755fdjz.com 点击:

 柴油发电机组在使用过程中的错误操作,错误操作一:

柴油机在机油不足时运转此时会因机油供给不足而造成各摩擦副表面供油不足,导致异常磨损或烧伤。为此,柴油发电机起步前和柴油机运转过程中要保证机油充足,防止由于缺油而引起拉缸、烧瓦故障。
错误操作二:
带负荷急停机或突然卸除负荷后立刻停机柴油机发电机熄火后冷却系水的循环停止,散热能力急剧降低,受热件失去冷却,易造成气缸盖、气缸套、气缸体等机件过热,产生裂纹,或使活塞过度膨胀卡死在缸套内。另一方面,柴油发电机停机时未经怠速降温,会使摩擦面含油不足,当柴油机再次启动时会因润滑不良而加剧磨损。因此,柴油发电机熄火前应卸除负荷,并逐渐降低转速、空载运转几分钟。
错误操作三
冷启动后未暖机就带负荷运转柴油发电机冷机启动时,由于机油黏度大、流动性差,是机油泵供油不足,机器摩擦面因缺油润滑不良,造成急剧磨损,甚至发生拉缸、烧瓦等故障。因此,柴油机冷却启动后应怠速运转升温,待机油温度达到40℃以上时再带负荷运转;机器起步应挂低速挡,并循序在每一挡位行驶一段里程,直到油温正常、供油充分后,方可转为正常行驶。
错误操作四
柴油机冷启动后猛轰油门若猛轰油门,则柴油发电机组转速急剧升高,会造成机上的有些摩擦面因产生干摩擦而剧烈磨损。另外,轰油门时活塞、连杆和曲轴受理力变化大,引起剧烈撞击,易损坏机件。
