SANY Hydraulic Gear Pump 9-Tooth PGP51016AF9R
FUNCTION
1. Efficient Hydraulic Energy Conversion: Precisely converts the mechanical energy output by the engine into hydraulic energy, supplying the hydraulic system with a stable and continuous flow of high-pressure fluid. The output flow rate is directly proportional to the rotational speed, ensuring a consistent supply of hydraulic power across various operating conditions.
2. Actuator Drive: Primarily powers the working implements of a loader-enabling complex, combined operations such as digging, lifting, tilting, retracting, and discharging-while simultaneously supporting the hydraulic requirements of the steering system or auxiliary attachments.
3. Multifunctional System Integration: Supports both single-pump and multi-pump configurations, allowing for either shared or independent fluid intake to flexibly meet the demands of complex hydraulic circuits. Certain configurations feature integrated components-such as priority valves and unloading valves-to further optimize system control.
Working Principle
As the gear teeth disengage, a vacuum forms on the inlet side, drawing hydraulic fluid from the reservoir into the spaces between the teeth. As the gears continue to rotate, the fluid is carried to the outlet side; when the teeth re-engage, the volume between them decreases, expelling the hydraulic fluid to generate a high-pressure output.
