СпутникиРНSpaceXРоскосмосNASATo meet the demands of a 10 MW-class diesel engine, a comprehensive structural design and analysis are conducted on the critical components of the high-pressure fuel pump. In the structural design of the oil outlet valve seat, two distinct layout schemes are proposed: Scheme 1 positions the oil outlet valve at the center of the valve seat with an opening, while the pressure relief valve is placed adjacent to it. In contrast, Scheme 2 symmetrically arranges both the oil outlet valve and the pressure relief valve on either side of the central axis of the oil outlet port. A multi-dimensional evaluation approach is employed to compare the two schemes, focusing on structural strength, deformation, sealing performance, and fatigue life. The results indicate that Scheme 2 outperforms Scheme 1 in all aspects and meets the operational requirements. Consequently, the final product adopts the structure of Scheme 2, while also providing valuable insights into the design of large-stroke diesel fuel pumps.
