In this article, we consider the possibility of using an integrated bearing beam and seal system in the place of classic separate bearing assemblies and mechanical seals for main pumps. The classification of possible states of main pumps is given taking into account the most characteristic types of incidents, failures, and accidents. As a result of the analysis (which was realized in this article), it was established that the most vulnerable components to failure are the bearing assemblies and mechanical seals, the specific number of failures of which is about 50% of the total number of main pumps failures. The main directions of the use of an integrated bearing beam and sealing system in the form of bearing and seal block (BSB) are indicated, the practical and scientific novelty of which consists in replacing the classical power unit of the pump equipped with rolling bearings on the bearing unit consisting of two single mechanical seals and a pair of plain bearings (radial and axis). This modernization allows increasing the life of main pump equipment, as well as its inter-repair interval. At the same time, it is ensured not only an increase in the reliability of the abovementioned bearing beam and seal system of the main pump but also an improvement in the quantitative indicators of reliability of the main pump remaining elements, in connection with the reduction of the overall vibrational and temperature background.
