Do you need help figuring out how to determine the right hydraulic fluid velocity for your hose assemblies? If you aren’t quite sure what to do, give us a call. Our team of hydraulic repair specialists has pretty much seen it all. We offer a full line of hydraulic services, including pump repair, motor repair, final drive repair, and on-site visits. Get in touch with us today for a repair estimate, or P and D on a new or remanufactured pump or motor.
Quick Tips to Determine Hydraulic Fluid Velocity
- When you replace couplings, make sure you use the same size.
- If you replace a hose with one that has a smaller inside diameter, you need to calculate the flow velocity.
- Use the Gates Fluid Flow Pressure Calculator to calculate flow velocity.
Hydraulic Hose Size is Important to Achieving the Correct Fluid Velocity
Suppliers of hydraulic hose assemblies will face this common scenario: An end-user brings in a worn-out hydraulic hose to be replaced, but the couplings needed for this particular size hose are out of stock, backordered or the store doesn’t stock the couplings needed to replicate the original hose assembly. However, you do stock the correct couplings in a smaller hose size inside diameter (ID).
The logical solution might be to rebuild the hose assembly using the smaller size hydraulic hose with a jump-size fitting. Though this may seem like a harmless solution, replacing a hose assembly with a smaller hose size than what was designed for that hydraulic system could cause unintended harm and create inefficiency to the equipment.
This injection molding machine relies on hydraulic hoses.
Flow velocity is determined by both the hydraulic pump’s flow rate and the hydraulic hose size. Changing the flow rate of the hydraulic pump but leaving the hydraulic hose size the same will affect flow velocity. In contrast, keeping the flow rate the same but changing the hose size will affect flow velocity.
Flow velocity is an important consideration when replacing a larger hydraulic hose ID with a smaller hydraulic hose ID. When an existing hydraulic hose is replaced with a new hydraulic hose that has a smaller ID, the same amount of fluid that was flowing through the original, larger hydraulic hose is now forced through the new, smaller hose. This will restrict flow and increase downstream pressure, thus causing flow velocity to increase.
