ANALYSIS OF A FUNCTIONING SYSTEM FOR RELIABLE OPERATION OF CENTRIFUGAL PUMPS

Abstract

The article analyzes both traditional and modern approaches to ensuring reliable operation of centrifugal pumping units used in the oil refining industry. Special attention is paid to the system of scheduled preventive maintenance: its strengths and disadvantages are revealed. The principles of maintenance based on the actual condition based on vibration diagnostics are also considered. The importance of an integrated approach, including forecasting the life of parts, is emphasized, which makes it possible to increase the efficiency and reliability of pumping equipment operation.

It should be borne in mind that the elements and assemblies of pumping units of oil refineries operate in difficult conditions, being simultaneously subjected to mechanical loads, high temperatures and corrosive processes. This leads to a change in the physico-chemical characteristics of materials, a violation of the geometry and dimensions of parts, and an increase in the gaps between the mating elements. As a result, there are extraneous noises, vibrations and premature breakdowns. Wear can occur naturally during proper operation, or it can be of an emergency nature – it can occur suddenly due to violations of the rules of technical operation. That is why competent maintenance and timely repair work are key conditions for reliable and safe operation of pumping equipment, as well as long-term maintenance of its operability.
