factor k in a bath spring system

[matteomb]

Good morning to all,

I ask for help for a calculation of a missing value for a study I am doing, I explain better:
I am using a homogenizer (piston pump) for some tests with a customer, who wants to "matemate" the system.
the missing data is that related to the value k of a group of a cup springs (10 + 10) encapsulated with this form: < < < < > > > > > > > > > > > > > > > > > > > > > > > > > > >
the dimensions of the single spring are: d 10 d 5.2 h 0.5, stainless steel material for springs.

Can you please help me?

an early thanks,

Matteo.

first take a catalog of springs a cup. identify the spring and you will get the elastic constant value. follow the catalog pages or look for the forum that we have talked about and determine the total elastic constant and the total deflection.
the developed force will not precisely linear will be given by k equivalent multiplied x racing.
then tie this to your pump regulation system.

I confirm what is said by mechanicalmg.
try looking for the schnorr catalogue because it definitely has the right references. I remember how long ago I used it for your own reason.

from the schnorr site we see that the spring in question is 001500a
being that you have two opposite packages where each package consists of 10 springs you calculate the equivalent constant and therefore the behavior is approximately that attached ± 5%.However on the serious catalogues of mug springs are the formulas for calculating the constant and running.
