Very nice i want to ask you something about making hydraulic test to have certificat because it's a pression équipement, i thing there are a tools to make it, if you have a data sheet for that or drawing please give it to me i work for a company in ammonia storage and we have a vertical pumps with mechanical seal and acumulator Thanks for help
Interesting, So the 'Fluid port assembly' is held in place by the rubber 'Anti extrusion ring' even at 100's of bar ? I would have thought it would have pushed it's way through ...
The anti-extrusion ring has a steel split ring sub-component which is not clearly seen in this video. If you can pause the video at one minute 31 seconds, you may be able to spot it. In the model accumulator as shown, it is in fact rated to 400 bar!
Hello Margi, To answer your question, our HYDAC bladder accumulators can be installed vertically, horizontally and at a slant. Note that when installing vertically or at a slant, the oil valve must be at the bottom. There are some specifications: on certain applications listed below, particular positions are preferable: - Energy storage: vertical, - Pulsation damping: any position from horizontal to vertical, - Maintaining constant pressure: any position from horizontal to vertical, - Volume compensation: vertical. If the installation position is horizontal or at a slant, the effective volume and the maximum permitted flow rate of the operating fluid are reduced. I hope that this will be helpful. Please, don't hesitate to ask more questions in comments if needed.
We have older bladder of 29L but now we have 35L, all dimensions are same as older. Please guide does it make any change or it will be OK in operation? Please guide
should inflate the nitrogen first, then install the seals. Also, it doesn't show the charging gauge, this is weird or may be for video demo purpose only...
Highly compressed oxygen is very reactive, and can explode by burning any oil present or even the bladder itself. Air at high pressure is also reactive. If you are interested search for bomb calorimeter to see how reactive high pressure oxygen can be.
what is the standard for refilling nitrogen in a 6 liter 330 bar accumulator bladder?
Boa tarde.
vocês disponibilizam cursos sobre manutenção de acumuladores.
Ola Diego. Nos temos o curso de Accumulators aqui na Australia. Veja mais informacoes no nosso site: www.hydac.com.au/hydac-training/ Obrigado!
Thanks for giving useful information.

Hello Mohammed. See more information about hydro-pneumatic accumulators on our website: www.hydac.com.au/products/accumulators/ Thank you
Your tools are great

Badass video rebuilding one now
thanx for video .
very nice, thanks for this video
Hi. If the accumulator blows and the nitrogen gets mixed with oil. Oil should be replaced?
Only if you need it to function
What are the methods of mounting these accumulators horizontally?

Thanks Sir 👍
Thanks Australia for clean technology@😊
Fantastic ✌️
Thanks a lot for sharing this video

Hello Ammad, thanks for your question. What we could suggest is to use genuine parts and follow the instruction guide of the manufacturer.
Thankyou🤲👍
Great! Thank you..

Great video..very informative.
Very clearly stated,thanks for sharing.
Why nitrogen gas is used in accumulator ; oxigen is why not?
Highly compressed oxygen is very reactive, and can explode by burning any oil present or even the bladder itself. Air at high pressure is also reactive. If you are interested search for bomb calorimeter to see how reactive high pressure oxygen can be.
Vikash Rawat because there is no oxygen; A flammable gas is a burning gas that can not be used to react with mineral oil and to ignite again.
