What are characteristic values for a piston pump?

Engineering Asked by John H. K. on April 20, 2021

For a piston pump you can calculate/measure things like,

  • Average Volume flow rate (m³/s)
  • Geometric Values (Surface)
  • Pressure over time
  • closing times of the valves
  • energy conversion efficiency $eta$

besides those, what charateristic values are there?

One Answer

Here are some other criteria:

  • Cycle time
  • Piston speed
  • Piston friction
  • Device lifespan (most likely a function of the number of cycles completed)
  • Number of suction/discharge ports
  • Type of valves used

Hope that helps!
