THE RESEARCH OF INCREASING THE RELIABILITY OF THE SEALING UNIT OF CENTRIFUGAL PUMPS

The article examines the causes of failures that occur in the sealing units of a centrifugal pump during operation. Centrifugal pumps are one of the most widely used devices in the oil and gas industry and manufacturing. Ease of repair and high performance compared to other pumps is one of the main factors for using these pumps. In the course of experiments carried out in practice, it was found that one of the most loaded parts of pumps are sealing joints. The pump sealing parts are checked every three months in accordance with the current maintenance schedule. The goal of the work is to improve the reliability of pump sealing elements. It is proposed to increase the reliability of pump parts by using various materials (graphite, rubber, polymer, etc.) in pump sealing units. The mechanical properties of the materials used in the knot were analyzed and evaluated in detail.
