[0015] Beneficial effects of the present invention:
[0016] (1) The plunger structure of the swash plate type plunger pump described in the present invention has a structure that, when the handle is manually turned, drives the first connecting rod to move downward near the second sphere. The downward movement of the first connecting rod near the second sphere drives the swash plate to increase its inclination angle.
[0017] (2) The plunger structure of the swash plate type plunger pump described in the present invention adopts a structure that is set so that when the inclination angle of the swash plate increases, the second arc block at the bottom will contact the arc plate when it rotates to the lower end. When the second arc block is squeezed and slides toward one end of the second sleeve, it will drive the connecting plate to slide toward one end. The sliding of the connecting plate toward one end will drive the ring to slide toward one end. The sliding of the ring toward one end will increase the contact area between the oil in the high-pressure oil storage chamber and the swash plate, which can reduce friction. By adjusting the swash plate angle, the pump can operate under the best working conditions, reduce energy loss and heat generation, and improve the working efficiency of the pump. The swash plate angle directly affects the stroke length of the plunger. When the swash plate angle increases, the stroke of the plunger increases, thereby increasing the amount of fluid pumped in each cycle, and increasing the displacement and flow rate of the pump. Conversely, reducing the swash plate angle reduces the displacement and flow rate of the pump.
[0018] (3) The plunger structure of the inclined plate type plunger pump described in the present invention adopts a structure that drives the cylinder to rotate while the connecting plate slides to one end. The rotation of the cylinder drives the scraper to rotate. The rotation of the scraper evenly spreads the oil on the contact surface of the sliding shoe to promote lubrication. By reasonably adjusting the angle of the inclined plate, the wear of the moving parts in the pump can be reduced, the failure rate can be reduced, and the service life of the pump can be extended.

When the second arc block 504 at the bottom rotates to the lower end, it will contact the arc plate 503. When the second arc block 504 is squeezed and slides toward one end of the second sleeve 506, it will drive the connecting plate 514 to slide toward one end. The sliding of the connecting plate 514 toward one end will drive the ring 515 to slide toward one end.

By adjusting the swash plate angle, the pump can operate under the best working conditions, reduce energy loss and heat generation, and improve the working efficiency of the pump. The swash plate angle directly affects the stroke length of the plunger. When the swash plate angle increases, the stroke of the plunger increases, thereby increasing the amount of fluid pumped in each cycle, and increasing the displacement and flow of the pump. Conversely, reducing the swash plate angle reduces the displacement and flow of the pump.
[0041] When the connecting plate 514 slides toward one end, it will also drive the fifth connecting rod 606 to move toward one end. The movement of the fifth connecting rod 606 toward one end will drive the rotating pin 605 to move toward one end. The movement of the rotating pin 605 toward one end in the guide groove 6041 will drive the cylinder 604 to rotate. The rotation of the cylinder 604 will drive the scraper 603 to rotate. The rotation of the scraper 603 will evenly spread the oil on the contact surface of the sliding shoe to promote lubrication. The structure is set up so that when the connecting plate 514 slides toward one end, it will also drive the cylinder 604 to rotate. The rotation of the cylinder 604 will drive the scraper 603 to rotate. The rotation of the scraper 603 will evenly spread the oil on the contact surface of the sliding shoe to promote lubrication. By reasonably adjusting the angle of the inclined plate, the wear of the moving parts in the pump can be reduced, the failure rate can be reduced, and the service life of the pump can be extended.
