Muito bom. Eu sou projetista da Fero/PARKER. E no momento estou desenvolvendo uma bancada de enchimento de acumuladores Hydac. Esse video me ajudou demais. Obrigado
Hi Joyce, Yes, we do :) Our Accumulators course has a major “Hands-on” component, where bladder accumulators are disassembled, inspected, assembled and pre-charged. Diaphragm and piston accumulators are also demonstrated. You can find more information and enrol online here: www.hydac.com.au/hydac-training/accumulators/ Thank you !
Um gás inerte é aquele que não sofre alterações quando submetido a determinadas condições. ... Argônio e nitrogênio purificados são os gases mais comumente usados como gases inertes devido à sua grande abundância na natureza (78% N2, 1% Ar no ar) e seu custo relativamente baixo. Resumindo: Se juntarmos o oxigênio, fluido hidráulico faltara somente somente uma fonte de calor para uma possível explosão e com o nitrogênio não tem esse problema.

1. How about removal of residual air prior to Nitrogen filling? And also after replacing the bladder in other video ( "How to Assemble a Hydraulic Bladder Accumulator")? After all, as you know, Nitrogen must have at least cleanliness class 4.0 and 99.99 vol.% 2. First, "remove the charge head from the adaptor" and only then "close down the Nitrogen bottle" - are you serious? Why not the other way around?
Thanks for your question! Point 1: We remove the air by rolling up the bladder, squeezing the air out before assembling it into the shell. Then the bladder is inflated with Nitrogen. A small amount of residual oxygen in an inert Nitrogen rich environment is not a problem. Point 2: The order of operation for this part of the task is not important once the system has been de-pressurised.
@@HydacAu Thank you for your prompt response! Sorry for question 2, because I missed the phrase about closing the control valve, and this step was not shown in the video.

what is the standard for refilling nitrogen in a 6 liter 330 bar accumulator bladder
A very informative video
Sir it is compulsory to use pressure regulator which is on the nitrogen cylinder ??
Good
How can i buy the charging unit in video
Thank you so much
Please explain us the working principle of a VACCUM DEGASSER
Do you have local contact in Indonesia? I need to buy recharging equipment for my hudraulic accumolator

You have branch here in the philippines?

Hello Mrs
I have 4 kg accumulater for transfer lathe how many bar neutrogen should be in an accumulater
The hydraulic pressure is 80 bar
70 bar
why we use only nitrogen to charged the bladder and we dont use other air is it the weight of nitrogen or what ?
nitrogen is an inert gas and cannot combust unlike air (oxygen) . because an accumulator is a pressurised vessel using air you can risk an explosion
because nitrogen is incompressible fluid

Is 35 litter accumulator maximum pre charge pressure 35 bar ?
how can buy the charing unit
