A power unit must deliver pressure for force and flow for speed while staying within motor, pump, valve, reservoir and thermal limits.<\/p>\n

1. Define Force and Pressure<\/h2>\n

Use cylinder area and machine load to determine working pressure, including linkage and pressure losses.<\/p>\n

2. Convert Speed to Flow<\/h2>\n

Flow equals effective area times piston velocity. Extend and retract can require different flow for equal speeds.<\/p>\n

3. Check Motor Supply and Duty<\/h2>\n

Battery lifts may use short bursts; production machines can cycle for hours. Electrical supply and thermal duty should follow the real cycle.<\/p>\n

4. Define Valve Logic<\/h2>\n

Direction, load holding, controlled lowering, regeneration and proportional motion are circuit functions. Send a schematic or motion sequence.<\/p>\n

5. Package the Reservoir and Service Access<\/h2>\n

Tank orientation, suction conditions, return path, fill\/filter access and hose clearance affect reliability.<\/p>\n

Frequently Asked Questions<\/h2>\n
\n
\nWhich comes first, cylinder or power unit?<\/summary>\n

Define the cylinder operating point and machine motion together.<\/p>\n<\/details>\n

\nHow does bore affect flow?<\/summary>\n

Larger area needs more flow for the same speed.<\/p>\n<\/details>\n

\nWhy does duty matter?<\/summary>\n

Motor and oil temperature depend on time and repetition.<\/p>\n<\/details>\n

\nIs relief a speed control?<\/summary>\n

No; flow\/circuit strategy controls speed.<\/p>\n<\/details>\n

\nWhat should I send?<\/summary>\n

Cylinder data, load, cycle time, electrical supply, valve sequence, duty and package constraints.<\/p>\n<\/details>\n<\/div>\n
