高压供油液体静压支承的典型应用是柱塞泵滑履的润滑(如图1所示)。高压柱塞泵的工作可靠性和耐久性,在很大程度上决定于滑履静压支承的工作情况,即滑履是否处于稳定的液体摩擦状态。过去,在分析柱塞泵滑履的静压润滑时,一般都不考虑高压油膜作用范围内的支承表面的“压力——弹件变形”。而实 High-pressure fuel supply Hydrostatic support is a typical application of plunger pump lubrication (Figure 1). The reliability and durability of the high-pressure piston pump depends largely on the working condition of the hydrostatic support, that is, whether the shoe is in a stable liquid friction condition. In the past, when analyzing the hydrostatic lubrication of piston pump shoes, the “pressure-elastic deformation” of the bearing surface in the area of ​​high-pressure oil film was not considered. And real
