belt and pulley system
(OP)
Hi! I have 2 pulleys and belt. My belt is damaged and new belt with this size can buy. I have belt which is 4 mm longer. I cant move pulleys to strain the belt. So i must take one pulley a little bit bigger. But i don't known how much bigger i need. Maybe someone can help?

I find it kinda hard to believe that a 1% change in belt length will have any substantial influence on your machine.

L=2C+1.57(D2+D1)+(D2-D1)^2/4C
C center distance between pulleys
D1,D2 pulley diameters
L belt length
For a change of pulley diameter, D1 I get
change in L=(1.57-D1/2C)*change in D1

you'd add a idler wheel about the mid of the belt run, welded to the compressor case, ideally in the plane of the belt run.
adjust the position of the idler with an internal/external thread (or a turnbuckle) to maintain belt tension.
clear as mud ?

Thanks for the math formula

Or ideally as others have suggested make a tensioner system, either provide a pivot for the motor or an idler wheel.

Some v-belt pulleys/sheaves are split and come with an assortment of shims. air cooled VW beetles, early Volvos, undoubtable others. Installing the shims between halves makes the sheave wider and act like a smaller diameter. Moving some shims from between the halves to the outside makes the sheave narrower and act like a larger diameter.
