SECTION 2 - INSTALLATION
General
The installation of the compressor with the associated driver and piping must be done with
care and precision. This section does not attempt to address all of the concerns that can
arise during installation. This section addresses some of the more critical installation consid-
erations and requirements.
Procedure For Setting and Aligning
The following points deserve special attention during the setting and alignment of the com-
pressor:
1. The skid design should:
Transmit compressor and driver reaction forces to the foundation.
Ensure that there is a proper mismatch between the shaking forces and the nat-
ural frequency of the skid.
Have sufficient stiffness and strength so that the compressor can be mounted
flat with no bending or twisting of the compressor frame, crosshead guides or
cylinder. This can be accomplished by shims or careful grouting.
Have enough stiffness and mass to resist vibration induced by the unbalanced
couples as specified in the Ariel Application Data Book.
2. The feet on the crosshead guides must be supported in a fashion that not only
provides vertical support but also prevents horizontal movement perpendicular
to the piston rod.
3. Each crosshead guide will deflect an amount relative to the weight of the cylin-
der mounted on that throw. This amount of deflection, which does not include
the weight of the pulsation bottles or piping, is shown in the Ariel Application
Data Book. Shims equaling the deflection value as listed on the cylinder outline
drawing are to be added to the shim pack under the crosshead guide, elevating
the crosshead guide to a level position. The crosshead guide supports must be
capable of carrying the combined weight of the cylinders, bottles and piping.
4. The compressor frame oil piping system and components are to be free of for-
eign matter including, but not limited to dirt, sand, rust, mill scale, metal chips,
weld spatter, grease and paint. It is recommended that a commercial pipe clean-
ing service be used to clean the oil piping system. If that is not practical, proper
cleaning procedures using cleaners, acids, and/or mechanical cleaning are to
be used to meet the cleanliness requirements. Cleaning by-products are to be
properly disposed; a disposal service is recommended. It is also recommended
that all oil-piping systems be flushed using an electric or pneumatic driven pump
and filtered clean production oil. All compressor frame cavities are thoroughly
