Resistance to flow causes pressure

Here’s another Flint Hydraulics Tech Tip: What causes pressure in a hydraulic system? This is one of the least understood facts about hydraulics. The answer to the question is simple – resistance to flow causes pressure in a hydraulic system. Hydraulic pumps do not “pump” pressure; they create flow. When the flow from the pump encounters resistance, pressure results. Need help troubleshooting? Call our team of experienced troubleshooters today at 901-794-4884 or email sales@flinthyd.com.   

Load resistance & pressure in a hydraulic system

Here’s another Flint Hydraulics Tech Tip: Load resistance is one of the main sources of pressure in a hydraulic system. How high will the pressure rise? Just as a horse will not pull any harder than required to move a load, similarly, hydraulic pressure will rise no higher than is necessary to move a load. Need help troubleshooting your system?

Force and Speed in Hydraulic System

Here's another Flint Hydraulics Tech Tip: The relationship between force and speed applies to all motion, no matter the means of transmitting power. When power is transmitted through a hydraulic system, speed is measured as flow rate - usually gallons per minute - and force is measured as pressure - usually pounds per square inch. An increase in speed or force means the power requirement goes up. If the flow rate (speed) of a hydraulic system doubles, the power from the system doubles. If the pressure (force) doubles, the power output of the system doubles. If both flow rate and pressure double, the output power of the system quadruples. Want to maximize your system's efficiency?

Force = Pressure x Area

Here’s another Flint Hydraulics Tech Tip: Pascal’s Law is the physical basis upon which the entire fluid power discipline is based. Mathematically, it is stated as Force = Pressure x Area, where force is measured in pounds, pressure is measured in pounds per square inch, and area is measured in square inches. It’s important to note that pressure is NOT the same as force; pressure is a measure of force per unit area – for example, pounds per square inch.
