LAP 3 - Principles of Hydraulic Pressure and Flow

Introduction:

It is important to understand the principles that allow power to be transmitted by a pressurized liquid. A good understanding of this LAP will help develop skills that are used in analyzing, specifying, and troubleshooting hydraulic components.

This LAP will provide foundation for understanding the theory of fluid power with the principles of pressure and flow. It will explain Pascal's Law and how it is used to multiply and transmit forces, how to determine cylinder forces, and how fluid flows.

Objective:

- Describe how to calculate the force output of an extending cylinder.
- Describe how to calculate the force output of a hydraulic cylinder in retraction (PULL).
- State Pascal's Law and explain its significance in hydraulics.
- Explain how force is multiplied using Pascal's Law.
- Describe two types of resistance in a hydraulic system
- Explain how Delta P describes hydraulic resistance.
- Explain how pressure is distributed in a hydraulic system
- Describe two methods of representing hydraulic pressure
- Describe how oil flows on the suction side of pump.
