浙玉渔3725船有台61212A-13G喷油泵总成,送本店修理调试。用户反映柴油机冒黑烟,油泵没力气、耗油大、转速不稳定。当时我们分析是柱塞磨损严重,调整器连接部件间隙配合过大、缓冲卡簧有断裂的可能。解体油泵部件检查,证实分析正确。接着清洗零件,更换部件,上试验台调试完毕,上机试车。柴油机发动后,主机油泵转速平稳,未出现异常声音,排气不冒烟。这时用户发现有三只缸高压油管接头处有漏油现象。就用扳手用力扳紧。事后想把空载转速用机械方式控制
Zheyu Jade Fishing 3725 61212A-13G Taiwan has a fuel injection pump assembly, sent to shop repair debugging. Users reflect the diesel black smoke, pump no strength, fuel consumption, speed instability. At that time, our analysis is a serious wear and tear of the plunger, adjust the gap with the connecting member is too large, the buffer retainer may be broken. Disintegration pump parts inspection, confirmed the analysis is correct. Then clean parts, replacement parts, commissioning on the test bed is completed, the machine test. After the diesel engine is started, the main pump speed is stable, no abnormal sound occurs, and the exhaust gas does not smoke. At this time, users found that there are three high-pressure oil tank pipe joints have oil spills. Tighten it with a wrench. After want to no-load speed with mechanical control
