Pumps, Motors and Integral Transmissions

Describes and systematically defines the principal technical characteristics, and allots letter symbols to these characteristics, and indicates how they can be more clearly defined by suffixes corresponding to particulate cases. Lists also an analysis of parameter dimensions. Gives examples for the use of symbols with suffix, and includes definition of terms without symbols.

Establishes the geometric displacements of pumps and motors having rotating or oscillating drives, and is also applicable to variable displacement units; in such cases, the values refer to the maximum displacement. The displacements specified may be used to derive other basic design criteria and normal ratings. Tabulates nominal values for diplacements from 0,1 up to and including 9000 millilitres per revolution.

ISO 13373-7:2017 gives guidelines for specific procedures to be considered when carrying out vibration diagnostics of various types of machine sets in hydraulic power generating and pump-storage plants (hydropower units). It is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical step-by-step vibration-based approach to fault diagnosis. In addition, it includes a number of examples for a range of machine and component types and their associated fault symptoms.
