What is the relationship between flow rate and hydraulic cylinder speed?

• A. Flow rate is the volume of fluid per unit time.
• B. Higher flow increases cylinder speed; lower flow slows it.
• C. Flow rate does not affect cylinder speed.
• D. Flow rate is the temperature of the hydraulic oil.

Answer: (B)

In hydraulics, the cylinder’s speed is driven by how much fluid is being delivered into the cylinder per second. More flow means more fluid is pushed into the chamber each second, so the piston displaces volume faster and the cylinder moves sooner, assuming the system can supply the needed pressure and the load lets it move. Less flow means less fluid per second, so the piston moves more slowly. Temperature or other unrelated terms don’t define flow rate. Keep in mind that actual speed can also be affected by load and pressure, but the direct link is that increasing flow rate increases speed.
