A power unit must deliver pressure for force and flow for speed while staying within motor, pump, valve, reservoir and thermal limits.
1. Define Force and Pressure
Use cylinder area and machine load to determine working pressure, including linkage and pressure losses.
2. Convert Speed to Flow
Flow equals effective area times piston velocity. Extend and retract can require different flow for equal speeds.
3. Check Motor Supply and Duty
Battery lifts may use short bursts; production machines can cycle for hours. Electrical supply and thermal duty should follow the real cycle.
4. Define Valve Logic
Direction, load holding, controlled lowering, regeneration and proportional motion are circuit functions. Send a schematic or motion sequence.
5. Package the Reservoir and Service Access
Tank orientation, suction conditions, return path, fill/filter access and hose clearance affect reliability.

Frequently Asked Questions
Which comes first, cylinder or power unit?
Define the cylinder operating point and machine motion together.
How does bore affect flow?
Larger area needs more flow for the same speed.
Why does duty matter?
Motor and oil temperature depend on time and repetition.
Is relief a speed control?
No; flow/circuit strategy controls speed.
What should I send?
Cylinder data, load, cycle time, electrical supply, valve sequence, duty and package constraints.
