8.5.2.1. Example for determining the maximum pressure pmax



The maximum compressor pressure pmax of the pneumatic system must now be determined. Starting from the working pressure of the consumer devices, all components in the pneumatic system must be taken into consideration:


Maximum working pressure in the system
Pneumatic network
Filters
Refrig.compressed air dryer

Minimum pressure in tank

The cut-in pressure pmin must always
be above this pressure.

Cycle differential of screw compressors

The cut-out pressure pmax is at least

Selected maximum compressor pressure
(cut-out pressure of compressor)
6 barop
Pressure loss 0,1 bar
Pressure loss 0,6 bar
Pressure loss 0,2 bar

6,9 barop



1 bar


7,9 barop

8 barop
