the inner wall of the movable ring seat 2 is provided with a groove, and the sealing ring 3 is arranged in the groove.
Preferably, the end face of the shaft sleeve 1 is matched with the end face of the step hole through a groove and a boss structure.
Preferably, the grooves and the bosses are semi-circular in cross section.
Preferably, the depth of the groove is 0.5-0.8mm, and the height of the boss is 0.4-0.7 mm.
Preferably, the mating grooves and bosses are paired.
Preferably, the sealing movable ring is sleeved on a shaft, the shaft drives the shaft sleeve 1 to rotate, and the shaft sleeve drives the movable ring seat 2 to rotate.
Preferably, the movable ring seat 2 is made of copper material.
Preferably, the cross section of the groove processed on the inner wall of the movable ring seat 2 is rectangular.
The invention has the advantages that: the improved sealing movable ring for the axial plunger pump is provided, so that the service life and the sealing performance of the sealing movable ring are improved, and the service life and the reliability of the plunger pump are further prolonged.

Detailed Description
A sealing movable ring for an axial plunger pump comprises a shaft sleeve 1, a movable ring seat 2 and a sealing ring 3, wherein a step hole is formed in the movable ring seat 2, the shaft sleeve 1 is sleeved in the step hole, and the end face of the shaft sleeve 1 is matched with the end face of the step hole through a molded surface;
the inner wall of the movable ring seat 2 is provided with a groove 5, and the sealing ring 3 is arranged in the groove.
Preferably, the end face of the shaft sleeve 1 and the end face of the stepped hole are structurally matched with the boss 4 through the groove 6.
Preferably, the grooves and the bosses are semi-circular in cross section.
Preferably, the depth of the groove is 0.5-0.8mm, and the height of the boss is 0.4-0.7 mm.
Preferably, the mating grooves and bosses are paired.
Preferably, the sealing movable ring is sleeved on a shaft, the shaft drives the shaft sleeve 1 to rotate, and the shaft sleeve drives the movable ring seat 2 to rotate.
Preferably, the movable ring seat 2 is made of copper material.
Preferably, the cross section of the groove processed on the inner wall of the movable ring seat 2 is rectangular.
The shaft sleeve is connected with the movable ring seat through the semicircular lug boss, the shaft sleeve is in interference fit with the transmission shaft, when the transmission shaft rotates, the shaft sleeve is driven to rotate the movable ring seat, the movable ring seat does not directly contact with the transmission shaft along with the rotation, and therefore abrasion is avoided, and the sealing ring well seals overflowing oil at the transmission shaft. The invention can improve the service life and the sealing performance of the sealing movable ring, thereby improving the service life and the reliability of the plunger pump.
