Hydraulic Calculations: Pressure, Pumps & Pistons

Click For Summary

Discussion Overview

The discussion focuses on hydraulic calculations related to pressure, pumps, and pistons, particularly in the context of a machine designed to hold a metal sheet coil. Participants seek to understand the relationship between hydraulic pump pressure and piston pressure, as well as the relevant formulas and principles involved in these calculations.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • Eng. Luqman inquires about the formulas needed to calculate the relationship between hydraulic pump pressure and piston pressure, specifically for a machine that holds an 8-ton metal sheet coil.
  • One participant suggests considering factors such as whether a single acting or double acting cylinder is required, the frequency of the machine's cycles, and space constraints when selecting pumps and pistons.
  • This participant also emphasizes the importance of knowing the required flow rate and pressure to specify a suitable power pack.
  • Another participant shares links to websites that provide useful hydraulic formulas, indicating these resources may assist in the calculations needed.
  • A later reply notes that one of the shared posts is four years old, which may imply a need for updated information.

Areas of Agreement / Disagreement

Participants appear to agree on the importance of understanding the application requirements for selecting hydraulic components, but there is no consensus on specific formulas or methods to calculate the pressures involved.

Contextual Notes

Participants have not provided detailed assumptions or specific definitions related to the hydraulic calculations, and there are unresolved aspects regarding the exact requirements for the machine in question.

Hi ...

Want to know about " How I can calculating ... Or ... Using which Formula " that is making me able to finde the relationship between the Haudraulic Pump Pressure and the Piston Pressure .?

on what i should depend when i want a piston and a hydraulic pump

For Example : I have a machine Decoiler for holding a metal sheet coil weighting ( 8 Tons ) from the side pressing the coil's holes .

I need help for this matter and need also hydraulic formulas ... please ... the principals ...

Eng. Luqman

With my best wishes

When making pump and piston selections, you need to consider a number of things. Firstly, consider your task. Do you require a single acting or double acting cylinder? How frequently will the machine perform its cycle? Do you have any space issues to consider? Select your cylinder based on your application, and then find a power pack to suit it. Your power pack basically has to provide the correct flow rate, and the correct pressure. When you know what these are, a power pack is relatively easy to specify.

Perhaps you could give us some more information about your requirements! I know English isn't your first language but if you give us as much information as you can then we should be able to help you out.
