Embodiment Construction
[0020] Specific embodiments of the present invention will be described below.
[0021] Such as figure 2 As shown, a plunger pair structure for an ultra-high pressure axial plunger pump includes a cylinder 4, a first plunger hole 401 for installing the first plunger 3 and a first plunger hole 401 for installing the first plunger 3 are opened in the cylinder 4 respectively. The second plunger hole 402 of the second plunger 5, the above-mentioned first plunger hole 401 communicates with the second plunger hole 402 to form a stepped hole, and the first plunger 3 extends into one end of the first plunger hole 401 by pressing The nut 7 cooperates with the end of the second plunger 5 extending into the first plunger hole 401 . On the cylinder body 4, also offer the small hole 6 that communicates with the first plunger hole 401, the central axis of the small hole 6 is perpendicular to the central axis of the first plunger hole 401, and the small hole 6 is not connected with the firs...
