Hydraulic Press actual Press Force (tons)

Click For Summary
SUMMARY

The discussion focuses on calculating the actual press force of a hydraulic press, specifically the Enerpac RC1510 with a maximum gauge pressure of 10,000 psi and an actual gauge reading of 2,500 psi. The calculation confirms that the actual pressure in tons is 3.75 tons, derived from the formula (2500/10000) X 15 tons. Additionally, using the effective area of 3.15 in², the force is calculated as 7,875 lb (or 3.9375 tons) at 2,500 psi. However, the contributor advises caution regarding the precision of these calculations.

Hi all. I am new to this site and I would like to verify the following calculation. Is it correct to do it this way? Please advise. Thanks.

Hydraulic Press: 15 tons (Enerpac RC1510)
Gauge Max Pressure: 10000 psi
Actual Gauge Reading: 2500 psi

Actual pressure (tons) = (2500/10000) X 15 tons = 3.75 tons
 
Engineering news on Phys.org
Yes. From the datasheet, the effective area is 20.3 cm², which is 3.15 in². Multiply this area by the pressure (in psi) to get the force in lb.

10 000 psi X 3.15 in² = 31 500 lb (or 15.75 ton)
2 500 psi X 3.15 in² = 7 875 lb (or 3.9375 ton)

But I wouldn't rely on these numbers if precision is important.
