AI Technical Summary
Spherical pumps experience unbalanced forces due to pressure differences between working chambers, leading to increased friction, energy consumption, and abrasion, primarily because of the fixed angle between the piston axis and the main shaft, which causes the piston and rotating disc to deflect, narrowing the gap and increasing friction forces.
A hydrostatic pressure support system is integrated into the spherical pump, featuring first and second liquid flow channels and pressure-bearing grooves on the slipper, which utilize hydraulic pressure to balance unbalanced forces, maintaining uniform gaps and reducing friction.
The hydrostatic pressure support system effectively balances unbalanced forces, reducing friction, power consumption, and extending the service life of the spherical pump by maintaining uniform gaps between moving parts, thus improving operational efficiency.
