Adding pressure gauge to floor jack.
Wearing latex gloves and getting hydraulic fluid everywhere is a good reason not to touch the.
The 20 ton heavy duty h frame shop press utilizes an air hydraulic power system that delivers up to 20 tons of pressing force.
Fyi it is a 35 tonne press with a hand operated jack.
By tapping the casting you are adding stress risers to something that may not be well engineered in the first place knocked off and not analyzed or tested or operating on the outer window of safety factor already.
40 000 divided by 6 6 666 pounds.
For instance with a 3000 psi gauge and a one inch area piston then it reads up to 1 5.
If you make the piston ten times bigger then the gauge reads in lbs times ten.
One thing i would do is derate the jack somewhat for example a 20 ton jack limit to the pressure equivalent to 12 tons.
Gauging hydraulic pressure from 0 to 50 000 psi.
Adding a pressure gauge to a hydraulic jack.
When components need to be removed or assembled this press delivers the controlled power to get the job done.
I want to add a pressure guage to a hydraulic press.
Idea copied off one of my pyro mentor s website.
The reason i want the guage is so that i can test the breaking strengths of various welds.
Enerpac hydraulic gauges and accessories supply a visual reference for system pressure and force.
We need a pressure gage that reads something over 6 700 pounds.
If you make the area of the piston exactly one square inch then the gauge reads in pounds directly.
Having a gauge on this jack lets me know how much weight it is lifting or when in the press how much force it is apply.
Remember to calculate the size of your piston.
The author points out that a jack with a 1 1 8 inch ram will be within six pounds per thousand of having the pressure gauge read directly in weight this means the 3000 psi gauge shown in the project should not be coupled to anything beyond a 1 5 ton 3000 pound jack.
You could also use it to calculate the weight of something very large like lifting a house.
Using the math discussed above we can calibrate the gage in tons adding marks on the face with a paint marker or other method.
Picked a 12 ton press off craigslist first thing i had to do was add a pressure gauge.
We may have to settle for a 10 000 psi gage realizing that the top 1 3 of the range is out of bounds for this jack.
