Совершенствование системы обслуживания и ремонта машинных агрегатов с электрическим приводом

Abstract

The share of electrically driven machine units at oil and gas enterprises is about 35% of all equipment used for technological processes, and the share of electrical energy consumed by them reaches 80% of the electricity consumed by these enterprises. This indicates the exceptional importance of the task of maintaining the required level and constantly increasing their operational reliability to ensure the continuity of technological processes, fire and industrial safety of enterprises, and the efficient use of energy resources. To solve this problem, on de enterprises of the industry began to introduce automated control systems for the maintenance and repair of dynamic equipment, containing in their composition automatic diagnostics systems, based mainly on the use of the vibration method.In this article, it is proposed to use the electromagnetic spectral diagnostic method based on the analysis of the parameters of the higher harmonic components of currents and voltages generated by the motor of an electric drive as an alternative to the vibration method in the systems of automatic diagnostics of machine units.
