How to Choose the Best Hydraulic Tanks & Reservoirs
Tank Capacity
Determine the required capacity by considering the total system fluid volume and accounting for expansion and contraction due to temperature changes. A general rule of thumb is to have a tank capacity that is two to three times the system's fixed operating volume.
Material and Construction
- Steel Tanks: Offer excellent durability and high-pressure resistance, suitable for heavy-duty applications. They are often powder-coated for corrosion resistance.
- Aluminum Tanks: Lighter than steel and naturally corrosion-resistant, making them ideal for mobile or corrosive environments.
- Plastic/Polyethylene Tanks: Cost-effective and lightweight, often used in less demanding applications. Ensure the plastic is compatible with hydraulic fluids.
Filtration and Venting
Look for tanks with adequate ports for filtration systems to maintain fluid cleanliness. Proper venting is crucial to prevent pressure buildup and allow for fluid expansion. Consider breathers with filtration to keep contaminants out.
Frequently Asked Questions
What is the primary function of a hydraulic reservoir?
A hydraulic reservoir stores hydraulic fluid for the system. It also helps dissipate heat generated during operation and allows contaminants to settle out of the fluid.
How do I determine the correct tank size?
Sizing depends on the system's total fluid volume, the pump's flow rate, and expected temperature fluctuations. A common guideline is a tank capacity of 2-3 times the system's fixed operating volume.
What are the differences between steel and aluminum tanks?
Steel tanks are generally more robust and suitable for high-pressure, heavy-duty use, while aluminum tanks are lighter and naturally resistant to corrosion, making them good for mobile or marine applications.
Why is proper venting important for a hydraulic tank?
Venting allows air to enter and exit the tank as fluid levels change, preventing vacuum or pressure buildup. It also helps prevent moisture and contaminants from entering the system.
