The inclined shaft plunger pump opens quickly and its structure is aging. Compared with swashplate axial piston pump, swashplate axial piston pump is generally composed of main parts such as cylinder block, cylinder plug, oil distribution plate, main shaft, variable organization, bearing, housing, etc. Swashplate axial piston pump is generally composed of main parts such as plunger, boots, oil distribution plate, cylinder block, etc. Let's see the difference between the two
1. The plunger in the inclined shaft plunger pump is driven by the connecting rod, the radial force is small, and the included angle between the transmission shaft and the cylinder shaft is allowed to reach 25 °, which now reaches 40 °, Cycloidal motor bm The discharge capacity of the pump is large. The inclined angle of the swashplate of the swashplate axial piston pump is bound by the radial force and generally does not exceed 20 °.
2. The pressure torque of the cylinder block is small, the cylinder end face and the oil distribution plate are even, and the leakage is small, Cycloidal motor rotor High volume power has small resistance loss and high mechanical power.
3. The structure is quiet and has good impact resistance.
4. The drive shaft of the inclined shaft pump must accept considerable axial and radial forces, so Plane flow distribution cycloid motor Thrust bearing with expanded load must be selected.
5. The total power rate of the inclined shaft pump is slightly higher than that of the inclined shaft pump. However, the inclined shaft pump has a large volume, and the flow scheduling is to complete the change of the included angle between the cylinder axis and the transmission axis by shaking the cylinder body. The inertia of the moving parts is large, and the dynamic care is slow.
6. Since the hinge can be well anchored, which is conducive to the return of the plunger, the inclined shaft plunger pump is allowed to work under the self-priming condition and low inlet pressure, and its self-priming function is better than the swashplate axial plunger pump.
The above is the difference between two different plunger pumps.
