initial No-load Rotational Test Run
Perform a low speed, no-load rotational test run, in the shop and in the field,
to mechanically check the driver and compressor at a minimum operating
speed. Refer to the No-Load Operational Checklist for the specific items to check
during the test run. The package control panel safety shutdown devices can be
functionally tested and adjusted.
During a no-load run, there is no “gas load” damping effect
on the reciprocating components and connecting rods.
Complies with ANSI Z535, ISO 3864, OSHA 1910.145 (f) (9)
During a no-load run, operating above 900
RPM
is not
recommended as excessive inertia loads may occur. For
special cases, get prior approval from the Packager.
Complies with ANSI Z535, ISO 3864, OSHA 1910.145 (f) (9)
In order to reduce the inertia forces of constant speed electric motor driven
compressors to acceptable operating levels, the inlet and discharge pressures
must be controlled immediately upon startup.
The duration of a normal no-load test run is 30 minutes.
