Hydrocyclone With Wear Detector

摘要

A wear detector comprising, a pressure vessel, a hydrocyclone, within the pressure vessel, a vibration or strain sensor, coupled to the hydrocyclone, for producing a data signal representative of a physical parameter of the hydrocyclone, means for transmitting the data signal out of the pressure vessel, and data analysing means, for collecting and analysing the data signal.

主权项

1. A wear detector arranged to detect wear in a hydrocyclone in a pressure vessel, comprising
a strain gauge mounted to the hydrocyclone and arranged to sense vibration of the hydrocyclone in use, and a signal processor coupled to the strain gauge and arranged to sample the strain gauge output to provide strain gauge data representative of the vibration experienced by the strain gauge as fluid flows through the hydrocyclone, the signal processor being further arranged to generate a current frequency signature for the hydrocyclone by analysing the strain gauge data to determine the energy density in a plurality of vibrational frequency bands, to provide an indication of the degree of wear on the internal surfaces of the hydrocyclone.
