Oblique shaft type piston pump opened earlier, the structure of the old. And swashplate type axial piston pump, inclined shaft type piston pump is generally cylinder block, cylinder plug, oil distribution plate, spindle, variable organization, bearing, shell and other primary parts, and swashplate type axial piston pump is generally composed of plunger, sliding boots, oil distribution plate, cylinder block and some primary composition. Here's the difference between the two:
1. The plunger in the inclined shaft plunger pump is moved by the connecting rod stock, and the radial force is very small, so the Angle between the transmission shaft and the cylinder axis is allowed to reach 25°, and it has reached 40°, so the displacement of the pump is large. The inclination Angle of the swashplate axial piston pump is bound by the radial force, generally not more than 20°.
2. The overturning moment of the cylinder body is very small, the end face of the cylinder body and the oil distribution plate are evenly fitted, the leakage loss is small, and the volume power is high; The resistance is small and the mechanical power is high.
3, the structure is quiet, good impact resistance function.
4. Because the transmission shaft of the inclined shaft pump needs to accept considerable axial and radial forces, it is necessary to select the thrust bearing to adjust the load.
5, the total power of the inclined shaft pump is slightly higher than the swashplate pump. But the volume of the inclined shaft pump, the flow scheduling by shaking the cylinder axis and the transmission axis of the cylinder axis Angle changes to complete, the inertia of moving parts, dynamic care is slow.
6, because the hinge can be better anchored, is conducive to the return of the plunger, the inclined shaft piston pump is allowed to operate under the condition of self-priming or lower inlet pressure, its self-priming function is better than the swashplate axial piston pump.
