Drawings (8-11).pdf

These are technical engineering drawings for a rotor assembly and condensate pipe system, created by Ingersoll-Rand for what appears to be a turbomachinery component. The first drawing (7X3194) details a rotor assembly and balancing specifications, showing intricate mechanical components like a gear pinion, nose impeller, thrust washer, and bolt assemblies. Specific notes indicate requirements for balancing procedures, impeller assembly guidelines, and cautionary instructions about grinding surfaces.

The subsequent drawings (7X3361 and 7X3665) provide detailed schematic views of a shell bearing thrust component and an assembly-condensate pipe (C-150), including cross-sectional views, dimensional tolerances, and geometric positioning. The drawings include technical specifications such as casting tolerances, geometric symbols, and precise measurements for various stages of the mechanical assembly, with annotations about air coolers, discharge points, and stage-specific configurations. The technical drawings are part of a detailed engineering specification set, likely for a complex mechanical system or turbine component.
