Development of Linguistic Rules Diagnosis of Failure in Centrifugal Pump for Use in Expert System
Operational failures in centrifuge pumps could be hydraulic or mechanical. However, most of these mechanical and hydraulic failures are connected cause of their operational nature and finding the right cause is due to considering numerous mechanical and hydraulic signs and parameters in pumps. On the other hand, due to non-linear and fluctuant behavior of pumps in the matter of time and not pre...

متن کاملExperimental Study on Centrifugal Pump to Determine the Effect of Radial Clearance on Pressure Pulsations, Vibrations and Noise
This article represents experimental study work carried out on a single stage diffuser type centrifugal pump. The flow-induced pressure pulsations, mechanical vibrations and noise has been monitored during the experimentations for five different flow rates by varying the radial clearance. For each case of radial clearance and flow conditions, overall levels and frequency spectra, in a wide freq...
متن کاملPressure pulsations in reciprocating pump piping systems Part 1: modelling
A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...
متن کاملExperimental Investigation of Performance Modification of Centrifugal Pump
Major industrial sector are using, most pumps are of centrifugal type. Centrifugal pumps are widely used because of their design simplicity, high efficiency & low maintenance. Modern centrifugal pumps are not complex machines. Despite the simplicity of design and production, centrifugal pumps are still capable of posing complex puzzles during their operation. The performance of a pump must be m...
