提高P系列喷油器总成清洁度的工艺技术

Technology for Improving Cleanliness of P-series Injector Assembly

介绍了国家标准及企业内部标准对喷油器总成清洁度的要求,通过对喷油器总成零部件毛刺产生机理的研究,提出了去毛刺的新方法,采用刷洗内螺纹、高压冲密封端面孔口、高压冲油道等去毛刺手段,能够有效提高喷油器总成清洁度,满足了喷油器总成性能要求,对喷油器总成零部件的清洗技术作了阐述。

Cleanliness requirements of national and internal standards for injector assembly were introduced in the paper. A new de- burring method was put forward through study of mechanism for injector assembly burr. Injector assembly cleanliness can be improved effectively with brushing internal thread, high pressure washing seal surface orifice and pressure flushing fuel channel to meet require- ments of injector assembly performance. Finally cleaning technology for injector assembly parts was elaborated.
