Help Identifying a pump and reservoir unit!

[Soulsolutions2020]

Good morning forum, I am new here and new to hydraulics in general. Although I Understand the principles of hydraulics and am learning about all the buzzwords like Volume, MFR, MAX PSI etc. etc. I am still just a noob and need some guidance. I was given a unit from a friend that I thought I could use for a project. As a knife maker, I want to build a hydraulic press for making damascus and san mai steel for use in forging knives. For the record I am extremely mechanical, somewhat knowledgeable with electrical and love building stuff.

So I have posted some images of the unit I have straight up! It was hooked up to a CJX2-12 Coil Volt 3 Phase One NO Motor Controller AC Contactor 660V 25A as you can see in the image. I need some help making sense of all this equipment and some direction on first steps to take. I have no idea the maker of this unit as there are no labels on the mtor or reservoir or even the pump. I did a quick search via ebay and came across a unit that appears to look exactly like my reservoir and it came up empty although the reservoir was a match, I did not see a maker on the motor or pump. My friend seems to think this came off of a forklift.

I am looking to build the following unit with the following capabilities.

1- A forging press, table top model
2- Run hydraulic ram that allows for a minimum of 20 tons of pressure double action.
3- Use a left handed or foot actuated controller for the unit.

I appreciate anyone's help and guidance in my journey!

First question is how you gonna come up wid 3Ø to make de motor turn.

Der no way dat pump came off forklift.

Should be connection diagram inside wiring cover.

When you try running pump install hose from outlet to inlet to minimize work load attempting to start.

Relief valve shows in picture so it possible to build constant run setup. Rest of your plan is valving and cylinder diameter situation. No point to getting into dat till you got pump running.

I can't tell you anything about it other than the fact that the text on the label is Korean. That may help you home in on the source. Maybe try google or something to translate

Looks like that unit has a single acting valve, so you would need something to retract the ram, like a set of springs.

I wouldn't be surprised if this unit came from a two post lift. Those usually use the lever to lift and lower, instead of a electric over hydraulic setup like a dump trailer.

Just be aware that it might be on the slow side for a 20 ton hydraulic press.

^^^^^
Yep, looks like an automotive lift, if thats the case it will most likely only operate a single acting ram as they are power up and gravity down.

Hi (removed), thanks for the reply, as for the turning of the motor, that is a good question. Like I said I dont know the first thing about these things. I was hoping to be able to run an on off switch to 220 volts. I dont have three phase so I may be SOL yeah? In your opinion is it even worth trying to make this work? It appears it can be wored for 120 or 220 volts as well.

You can get a 220v 2-phase to 220v 3-phase converter. I've got one on my Bridgeport mill. But I doubt if that motor is 3-phase with those capacitor boxes hanging off the side. And there'd be more than two wires sticking out. You'll have to open it up and see how it's wired. I agree with the others that say that looks like an auto-lift unit--No dual action out of that.

Dang, oh well at least it was free!

I opened the end and there was a board with some wires and a thin horseshoe piece of steel, like a connection or ground perhaps, I could use it as a single phase no problem, I dont need super fast action and the movement will only be 4" to 6" at a time. I could put some heavy springs for teh up i guess right?

You are right it is not three phase, it was wired for 220, or at least that is the where the wires were connected on the circuit box. Appeared they had a key switch attached in between for on off or locking it.

Since there appears to be only one work port I suspect running the motor would supply oil to the lift & with motor off the handle would lower the load. If this is correct then you could plumb that port to a 4 way 3 position valve to control a double acting cylinder. You will need a way to connect the tank line to the reservoir below oil level though for this to work. You would not use the manual valve on the power unit.

 

[Soulsolutions2020]

I am going to disassemble the unit so you can see hte pump. I see a few ports, one is closed off but appears to be a through port, maybe they just used it for one action??

 

[user.69169]

You disassemble, BE REAL CAREFUL. Most likely springs and balls dat fly real good in dem holes.

Still guessing game dis point, Open box where wires connect and got better chance.
Nameplate confusing. Maybe dey use single nameplate for different units wid different motors.

If 3Ø gonna have 3 wires connected to motor windings. Single Ø gonna be either 2 or 4.
Nameplate not reliable.

Like said, gotta prove motor first.

 

[Soulsolutions2020]

Om this is the motor rear removed with all wiring exposed.

 

[user.69169]

Starting switch all de evidence you need say it Single Phase motor.

Next gotta determine voltage set up for to run.

Make sure you get all shimming washers back in when reassembling.

Sure looks to be a standard car lift hydraulic pump.*
Power up and gravity down. For down U opened the valve to let oil return to tank.

The valve/lever can be replaced by a solenoid type be it 12,24 but will be hard to find.

*we used 4 post lifts to make into freight elevators and added remote controls and all kinds of safety features hence need for solenoid valves.
(lifts also required air for safety features)

Many similar units were made for 12 VDC and used on, example, lifting tail gates.
And, yes they also made 2 way units. (power in, power out)

If you want return you could always use HD springs to accomplish that function but it will never be rapid nor would an actual double action hydraulic cylinder.
I am assuming you really are wanting some sort of hammer mill machine.

 

[user.69169]

Pretty much standard lift pump/snow plow pump wid internal valve. Just need to run return line back to fill port and rest of machine is external valves to perform function needed.
I'd set it up like portable Enerpac pump wid 2 hoses. Dat way 1 pump can run several machines instead of one pump per machine.

Problem is how much flow pump is going to develope wid single phase motor. Nameplate looks like it derates FAST on single phase.
Possibilitys are endless, as long as flow is sufficient.
