Hydraulic Systems Calculations Approach Flashcards
1
Q
For Pressure Control Valves, how is the minimum area approximated in Q = CdAo*SQRT(2delP/rho)?
A
Approximate the area as a strip, with the length of the circumference and the width of the opening (may need to be calculated from trigonometry)
2
Q
For Regenerative Circuits, how are flow rates dealt with?
A
For the extending stroke, the flow rate into Port A = flow from pump + flow from Port B, and vice versa for the retracting stroke.
3
Q
For calculating Pump Displacement, when to use Pitch Circle Diameter?
A
Used in calculating the piston displacement using trigonometry.
