Flow rate determines speed

Here's another Flint Hydraulics Tech Tip: A flow control valve changes the flow rate of a cylinder. Flow rate determines cylinder speed of extension and retraction and therefore, the speed of blade movement. Flow control valves increase or decrease flow rate by means of an adjustable internal orifice; the smaller the orifice through which the oil is forced to flow, the lower the flow rate to the cylinder.

Resistance to flow

Here's another Flint Hydraulics Tech Tip: If a faucet is partially closed, it resists flow by forcing all the flow to pass through a smaller opening. A gauge upstream of the faucet inlet will show an increase of pressure. Closing the faucet a bit will not necessarily reduce the flow rate out of the faucet. If there is no other flow path, the pressure will rise to the level required to push the full flow rate through the smaller opening. Need help troubleshooting?

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?

Flow rate vs. flow velocity

Here's another Flint Hydraulics Tech Tip: Most hydraulic system users are familiar with the term "flow rate," but "flow velocity" is just as important. Flow rate is the volume per unit of time, whereas flow velocity is the distance per unit of time. Excessive flow velocity can cause oil aeration, power loss, system overheating and other problems. As a rule, undersized hydraulic plumbing causes excessive velocity. Need help troubleshooting? Call our team of Certified Fluid Power Specialists today at 901-794-4884 or email sales@flinthyd.com.
