hydraulic pneumatic connection in automation studio

hydraulic pneumatic connection in automation studio

hydraulic pneumatic connection in automation studio

(OP)
in automation studio hydraulic and pneumatic modeling are two seprate parts. is there any way to model a tank which has one input at the top and one output at the bottom. gas enters from the top and oil goes out from the bottom. I mean converting pneumatic pressure to hydraulic pressure and flow.
any help is appreciated.

Use the accumulator function.

what do you mean by function?
how can i define a function?

RE: hydraulic pneumatic connection in automation studio

There are built in tools within the software.

Pumps, cylinders, motors... Etc...

What you have described is an accumulator. Use the built in tools that already defined.

I am using automation studio 5.2 and it does'nt have any accumulator tool with two connections in its libraries. only there are accumlators with one connection.
Is there any shuch accumulators in automation studio? if yes how can I add that to the library?

What are you trying to simulate?

Setting the nitrogen precharge pressure to simulate an air supply pressure will give the same performance, up to a point. If you don't need to consider dynamic response and you're not concerned with polytropic values of the gas/air.

If you do need to consider a dynamic response, then you'll have to create a model with a pneumatic input.

I have a hydraulic circuit and a pnematic circuit. In one point I want to link these two circuits together and transfer the pressure at that point in the hydraulic circuit to the pneumatic circuit.
I know that there exists two-connection accumulators and also hydropneumatic transfer actuators that convert hydraulic pressure into pneumatic pressure and vice versa. But I cant find thses tools in AS 5.2 library. If you help me on how to get these tools and add them to AS library that would be a great help.
thanks

Do you want a 1:1 conversion? Can you use a pressure gauge or transducer function to feed the actual pressure into the next calculation?
Is there an intensifier function, that can be set at 1:1 ratio?

RE: hydraulic pneumatic connection in automation studio

(OP)
yes I want a 1:1 conversion. then how can I do it?

You can use a pressure transducer to measure the pressure of the pneumatic side and then put a hydraulic supply unit linked to the reading it gives to provide you with the correct pressure.
