Hydraulic Oil Tank – Frequently Asked Questions

1. What is the main function of a hydraulic oil tank in a hydraulic system?

A hydraulic oil tank stores the hydraulic fluid and performs other critical tasks: cooling the oil, separating air, supporting filtration (e.g., via integrated return line filters), compensating for volume fluctuations (e.g., during cylinder extension/retraction), as well as integrating monitoring elements such as level indicators and sensors.

2. Which materials are typically used for hydraulic oil tanks and what advantages do they offer?

  • Steel: High stability and durability; often painted or galvanized; ideal for large, stationary systems.
  • Stainless steel: For increased corrosion protection requirements.
  • Aluminum: Lightweight, good heat dissipation; suitable for compact or mobile systems.
  • Plastic: Low cost, corrosion-resistant, and lightweight; limited service life under mechanical stress.
  • Special materials (e.g., carbon): For extreme lightweight applications, such as in aerospace.

3. In which applications are hydraulic oil tanks used?

Used in stationary machinery (machine tools, presses, production equipment) as well as in mobile machinery (construction machinery, agricultural equipment, forklifts). Also in special-purpose machine building, vehicle hydraulics, and industrial automation.

4. What advantages result from using a well-selected hydraulic oil tank?

  • Safe, regulated oil supply
  • Longer component lifespan through filtration and cooling
  • Optimized space utilization through modular designs
  • Ease of maintenance through drain plugs, oil level indicators, and sensor integration

5. How important is maintenance for the service life of a hydraulic oil tank?

Regular maintenance is crucial: check oil level, replace filters, inspect for leaks. Drain valves and good accessibility simplify servicing. Metal tanks can last for decades with proper care; lighter plastic tanks age faster (brittleness) – maintenance is especially important here.

6. Which factors should be considered when selecting a hydraulic oil tank?

  • System requirements: oil volume, temperature, pressure
  • Installation situation: available space at the installation site
  • Material requirements: weight, corrosion protection
  • Additional equipment: filters, sensors, breathers
  • Ease of maintenance & installation effort

Careful selection is essential for long-lasting, efficient operation.

7. What sizes and designs are available for hydraulic oil tanks?

Capacities from a few liters (small power units/mobile hydraulics) to several hundred liters (construction machinery/industrial use). Designs: flat, round, or custom tanks – adapted to installation conditions and space requirements.

8. Which specific components can be integrated into a hydraulic oil tank?

Possible integrated components enhance functionality and ease of maintenance:

  • Return line filters (e.g., 10 µm, defined connection size, max. return flow)
  • Drain cocks/valves for easy emptying
  • Integrated level indicators and sensors for oil level monitoring

These components increase efficiency, cleanliness, and serviceability of the hydraulic system.
