The invention discloses a texturing design method based on plunger pair surface pressure partition, which comprises the following steps: (1) determining working conditions of a plunger pump, including working pressure and plunger surface linear velocity, and (2) solving design pressure Ps1. (3) solving a local design pressure Ps2; and (4) dividing an oil film pressure zone to obtain an oil film pressure zone model. (5) determining a low oil pressure area, a middle transition area and a high oil pressure area based on the oil film pressure partition model, and (6) determining the maximum oil film pressure corner and the area range. And (7) determining a micro-texture design region range. And (8) optimal microstructure parameters are designed. According to the invention, the oil film pressure on the surface of the plunger is partitioned, and micro-texture antifriction design is carried out on high oil pressure on the surface of the plunger, so that the wear of the plunger can be reduced in ...
