In this scenario, a 3-inch bore cylinder should provide a robust condition. Calculated out this gives a hydraulic horsepower of 23.34. Example: Calculate hydraulic horsepower when pressure is 2000psi and flow rate is 20GPM: Horsepower (2000 x 20) / 1714. This equates to 14,130 psi of holding force (7.065 square inches X 2000 hyd psi). To find hydraulic horsepower, use the equation: HP (PSI X GPM) / 1714. The friction behaviour of a hydraulic cylinder. Then multiply this number by the 2,000 hydraulic psi being used. Often pressure sensors are used to measure the chamber pressure conditions for calculating the loading force. For thick cylinders such as guns, pipes to hydraulic presses, high pressure hydraulic pipes. If you use a 3-inch bore cylinder, calculate the radius (1.5 x 1.5 x 3.14), which equals 7.065 square inches of surface area. Measure the diameter of the piston of the hydraulic cylinder with the ruler. For example, for 2,000 psi of hydraulic pressure, calculate the surface area of the bore diameter, which is 3.14 X R2. To get the hydraulic cylinder tonnage, divide the pound force by 2,000. Let’s take a stab at determining the required hydraulic cylinder bore size by calculating the surface area of the cylinder bore size and the hydraulic pressure being used on the machine or hydraulic pump cart.
If we multiply 10,000 by 1.5 ratio, we find that we need approximately 15,000 pounds of force to counteract the cavity pressure.
For example, if expected cavity pressure was 10,000 psi and the cavity surface area of the component was 1 square inch, we know that there would be 10,000 pounds of force acting on the component (10,000 pounds per square inch X 1 square inch). Ram cylinders usually have no piston but rather use the cylinder rod as the.
Typically, I will design the bore size so that it exceeds the cavity pressure force by 1.5X to ensure robustness. Basically, the pressure of a hydraulic fluid forces a piston to move in. 3.Determine the bore size of your cylinder.
