DIAGNOSING SYSTEM FOR FLUID MACHINERY

Title:

DIAGNOSING SYSTEM FOR FLUID MACHINERY

Document Type and Number:

WIPO Patent Application WO/1999/051883

Kind Code:

A1

Abstract:

A diagnosing system for fluid machinery capable of finding wasteful energy consumed around the fluid machinery, comprising a first identifying means for identifying the characteristics of the fluid machinery represented by a flow rate-lift characteristic by receiving specified information on the fluid machinery to be diagnosed, a second identifying means for identifying the operating flow rate or operating pressure of the fluid machinery according to the relationship between the identified characteristics and a measured operating pressure or operating flow rate of the fluid machinery by operating the fluid machinery to be diagnosed and receiving the measured results of the operating pressure (lift), operating flow rate, power consumption, or operating electric current of the fluid machinery in operation, and a processing means for computing variations in an operating flow rate, operating pressure, or power consumption when the revolution speed of the fluid machinery to be diagnosed is changed and displaying the computed results.
