Hydraulic accumulators are considered to be the muscles of a hydraulic system. They are storehouses of energy and help ensure that everything goes smoothly. But also like muscles, they have to be the right size to work properly. This is where the sizing of the hydraulic accumulator comes in.
The importance of getting the hydraulic accumulator sizing right so your hydraulic system runs without a hiccup. If the accumulator is too small it will not have the capacity to store enough energy. But if it is, it can be a space suck and a cash suck. That's why it's so important to size them just right.
There are several key considerations needed for calculating these sizing factors including the size and pressure of the system, how frequently it is utilized, and how much power it needs to store. It’s like deciding how much food you should eat to have enough energy to play all day. If you do not eat enough, you will run out of energy. But if you eat too many, you might have a tummy ache.

Get your system running better with precise hydraulic accumulator sizing and improve system performance. It’s like the right amount of fuel in a car — not too much, not too little. When things are all set, the system may work best.

Hydraulic accumulator sizing challenges can either be related to availability of space for a large accumulator or the cost constraint to afford an expensive one. But there are strategies to surmount these obstacles. Perhaps you might experiment by using a smaller cumulation or by adding more if necessary, or by looking for less expensive sources that do the job.

It’s true that investing in the right size hydraulic accumulators for your system is worth the effort. It can also keep your system running efficiently and save you dollars on the life of your energy bills and save even more by avoiding damage due to fluctuations of pressure. It’s like having the right size shoes — they enable you to walk without pain, without developing blisters.
