The reliability increase of the electric drives for pumping units

Abstract

Improving the quality and reliability of electrical machines is one of the most urgent problems of modern electrical engineering. Practical data show that the increase of service life and reliability of machines gives better results than the improvement of other technical and economic indicators: efficiency, power factor, utilization factor. The quantitative indicators of reliability can be best determined by the results of statistical processing of the information obtained when using the products.
 An algorithm of the load balancing based on the actual performance of pumping equipment and temporary changes in the connected load via the emergency shutdown of the pumps has been developed to improve the reliability operation and reduce inefficient energy losses. The main advantage of the proposed method is the analytical design models of optimization, which does not require numerical methods and iterative procedures. 
 Such principles as active-preventative service and increasing personal responsibility for its quality and timeliness should be the basis for the organization of workposts service. 
 Progressive forms of service are the technical re-equipment, modernization of equipment and improvement of production organization, as well as complex methods of the electric drive maintenance and application of the system of standardized tasks.
