METHOD FOR CONTROL OF TECHNICAL CONDITION OF SHIPBOARD CENTRIFUGAL PUMPS IN OPERATION Russian patent published in 2020 - IPC G01M15/00 F04B51/00 F04D29/00 F04D29/66 

FIELD: shipbuilding.

SUBSTANCE: invention relates to ship auxiliary equipment system, in particular, to means of measuring vibroacoustic parameters of auxiliary equipment. It can be used for evaluation of technical state of auxiliary mechanisms, as well as for determination of causes and levels of vibration values of shipboard centrifugal pumps in operation. It retrieves the vibration signal in the vertical, axial, transverse directions from sensors installed on the elements of bearing assemblies and feet of marine centrifugal pump. Optimum mode of load and control of technical state of ship centrifugal pump in operation is established based on obtained vibration parameters, namely values, vibration speed, vibro-displacement at corresponding frequencies of operation mode of elements of bearing assemblies and on feet of centrifugal pump.

EFFECT: higher reliability.
