ABSTRACT:
An apparatus and method for enhancing the efficiency of the centrifugal separator automatically adjusts in accordance with operator input for varying amounts of solids in contaminated fluid being passed through the separator. A load sensing circuit monitors the load on the drive motor of the centrifuge bowl and a second load sensing circuit monitors the load on the drive motor of the scraper vane. The apparatus further includes a variable speed motor designed to vary the gravitational force with which the centrifuge operates in response to a variety of factors regarding particle size and specific gravity. The load sensing circuits optimize cleaning cycle frequency and reduce failure due to mechanical stress. The load sensing circuits taken in combination with the variable speed drive provide the ability to efficiently and variably monitor the cleansing intervals to provide predetermined levels of cleansing and prevent the overloading of the scraper and scraper mechanics.
