AI Technical Summary
Technical Problem
The assembly of existing plunger pumps is difficult because the sealing structure and the output end of the power structure are not coaxial.
Method used
It adopts a self-correcting sleeve and limiting flange structure, and adjusts the relative position of the plunger seat and the plunger shaft by slight offset, and maintains a stable connection with O-ring.
Benefits of technology
This technology enables convenient assembly of plunger pumps, improves assembly accuracy and stability, and extends service life.

Abstract
本实用新型提供了一种超高压柱塞泵用自校正柱塞装配结构，包括传动结构以及柱塞轴，传动结构用以驱使柱塞轴沿轴向滑动，传动结构的输出端设置有自校正套筒，柱塞轴的下端设置有柱塞座，柱塞座活动设置在自校正套筒中，柱塞座的下端设置有自校正弧面，自校正弧面与传动结构的输出端相抵接，且自校正弧面与传动结构的输出端的接触为点接触。组装时，控制柱塞轴的上端从密封结构中穿过，控制柱塞轴的下端与柱塞座插接固定。若上述过程中，密封衬套的内孔与柱塞座的上端开口因公差原因未能保证同轴，则将控制柱塞轴下端与柱塞座插接固定的过程中，可控制柱塞座于自校正套筒中发生微小偏移，用以与柱塞轴相适配。
