Essential Considerations for Hydraulic Power Unit Sizing

When it comes to designing and installing hydraulic systems, understanding the sizing of your hydraulic power unit is fundamental. A correctly sized power unit is crucial for efficient operation and longevity of the system. Here we delve into the critical aspects you should consider during the sizing process.

Understanding Your System Requirements

Before jumping into calculations, it's essential to have a comprehensive understanding of your system's requirements. This includes the operating pressure, flow rate, and power needs, which are pivotal in determining the right unit size. Every component of your system, from actuators to valves, contributes to the overall requirement of your hydraulic power pack.

Flow Rate and Pressure Considerations

The flow rate and operating pressure are the primary drivers behind the size of your hydraulic power unit. Higher flow rates and pressures require more robust and capable systems. Consequently, these factors will guide your calculations in choosing a unit that meets these demands without overburdening the system.

Calculating Power Unit Size

Performing precise calculations is the key to selecting a power unit that matches your needs. Use the following formula to calculate the required power: Power (kW) = (Flow rate (l/min) * Pressure (bar)) / 600. This equation helps determine the necessary horsepower to drive your system effectively.

Choosing the Right Power Unit Components

Once you have a clear idea of the required power and capacity, it's time to focus on the components of the power unit. This includes selecting the right pump, motor, reservoir, and ancillary components like filters, coolers, and controls, which all play a part in the efficient operation of your power pack.

Margins for Future Expansion

Consider the potential for future system upgrades or expansions when sizing your hydraulic power unit. It's prudent to allow a margin in your calculations for additional capacity, to accommodate any anticipated increases in demand without necessitating a complete overhaul of your existing unit.

Energy Efficiency and Cost Savings

Implementing an appropriately sized power unit not only optimises the performance but can also lead to significant energy savings. An oversized unit can result in unnecessary energy consumption, while an undersized one may work harder, consume more power, and reduce the lifespan of the system.
