某型柴油机调喷器国产化研制

Production Domesticization Research of Certain Adjustable Orifice

调喷器是某型号大功率柴油机保证燃油喷射系统,能够在特定的时间条件下准确、稳定地供油的关键件。前期装配一直采用进口件,周期长,成本高。通过针对产品结构与精度的分析,研究了适宜性工装,优化和改进了工艺方案及试验台的改造研究,并在工艺试验的基础上,突破了加工的关键技术,为某型号柴油机的国产化改进提高提供了可靠的技术保障。

The adjustable orifice is a key part which can make certain large diesel engine ensure fuel injection system to supply oil exactly and stably in specific time. During early assembly, the imported parts are adopted which have long cycle and high cost. The paper analyzes the product structure and precision and researches adaptable technical tools, and optimizes technical program and bench test. On the basis of technical experiment, a key technique for manufacturing is broken through, which supplies reliable insurance for production domesticization.
