What is an accumulator?

We decided to start with the basics:
What is an accumulator?
How can I use an accumulator?
What are the different technologies that we have on an accumulator?

Thank you for the explanation. I was having trouble with a press at work, machine repair took the accumulator tank off said that we did not need it, the press has not ran right sense. One of the main things that it is doing is pulsating violently

Sir wonderful explanation... Easy to understand.. thank you so much

[KennedyTendayi]

This is awesome, such a clear explanation

Thanks sir.. all respect you will get more followers and like

Where will we install the accumulator on the system?

Greeting Sir,
What will be the pressure in nitrogen bladder as compared to hydraulic side? For example if hydraulic pressure is 30 psi then what will be the nitrogen bladder pressure to work perfectly

[a.m.]

I though this was for extra sensory perception. This was interesting anyways. Thanks. Does Nitrogen bladder or diaphragm accumulators operate well in cold temperatures?

I was thinking of using an accumulator for a press that I am designing because of the low loading rate required. Is it a valid application for accumulators?

I love how the “it’s a pressure accumulator! Why don’t you get it?!” are wrong and not getting how a pressure accumulator works. One, that’s not what the video is claiming. Two, pressure accumulators are for pressure surges. Three, the air in the bottle needs to be a comparable pressure to the system pressure. Four, pressure accumulators are for hydraulics and hydraulics are closed, not flowing fluids, systems. Five, say the system is closed (water off) and there is water hammer, the pressure surge would go into the bottle and continue through the pipe (I’m a firefighter and deal with this. One hose causes the water hammer and all the other hoses feel it). Bernoullis principle is have a fun time with your “pressure accumulator.”
