Hydraulic tank volume
The main rule for hydraulic tank sizing is: “bigger is better”, but because there is not always exist a possibility to find a lot of space for the tank (mostly in mobile applications) we need to know and follow min requirements for system calculation.
Just wanted to summarize all info I have for estimation of hydraulic tank volume:
| Min. value | Recommendation |
|---|---|
| Industrial application – Mineral Oil | |
| 2.5 times of all pumps flow + 10% for air cushion | 3..5 times of all pumps flow + 10% for air cushion |
| Industrial application – HFC/HFD | |
| 5 times of all pumps flow + 10% for air cushion | 8 times of all pumps flow + 10% for air cushion |
| Mobile application – Open loop pumps | |
| 1.5..2 times of all pumps flow + 10% for air cushion | 2.5 times of all pumps flow + 10% for air cushion |
| Mobile application – Close loop pumps | |
| 1..2 times of all CHARGE pumps flow + 10% for air cushion | 1.5..2 times of all pumps flow + 10% for air cushion |
Please correct me if I’m wrong.
