Hydraulic Power Pack Unit

08/07/2009 4:23 AM

dear all mechanical engineers

we are the manufacturers of induction furnace up to 30 ton. to take out metal from the furnace we use to tilt the furnace with the help of hydraulic cylinder(powered by hpu).

can you please tell me the exact procedure for selecting

1. power pack.

2. hydraulic pump

3. valves.

or you can just tell me the website.

thanks in advance

Depending on which country and region you are in, get hold of an hydraulic power pack supplier (use the google with the request)

In case you don't have an hydraulic designer with you, tie-up with one of them, use his expertise, ask him to design the hydraulic system for you.

There are many good one of them.

Best is to try one who makes the power macks for the machines.

Of course it is a simple circuit and if you have the necessary designs, it is easy to buy the parts.

Based on the loads and the stroke design the cylinders.

Based on the pressure and the speed, the pumping unit. That selects the pump (possibly gear pump for you)

Then the necessary valves relief, check, etc.

Look in the "Formula" Section of this Ebook on page 14-15 to see the standard process for sizing a Hydraulic Circuit. Page 16-17 covers Pneumatic circuit sizing.

http://www.hydraulicspneumatics.com/200/eBooks/

These are items required in general terms and will not make an experienced Circuit Designer out of anyone. So many things on a given circuit can change parts of any writeup on how to size a circuit that only someone with a lot of experience should actually attempt circuit design. Someone who knows the right questions to ask to make the circuit design process give the correct setup.

However the lack of training in all things dealing with Fluid Power leads a lot of mistakes until the College of Hard Knocks" training is complete.

Most holding or melting, tilting furnaces come with their own pre-specified hydraulic units.

I would align your self with an application engineer specific to fluid power applications.
