Definitions

  • the dimensions of the tool will also affect its performance. If the weight of the piston is changed or the length of the stroke of the piston is changed, the impact produced and frequency of piston stroke at a given fluid pressure will be different. Thus, the tool can be designed to operate effectively on various input pressures. The total size and weight of the tool, of course, affects its maneuverability so must be considered in any changes made.
