Analysis of Mechanical Seals for High-Speed Centrifugal Gas Compressors

Parallel abstracts


A study aimed at seal selection efficiency for centrifugal pumps in the oil and gas industry is presented. A detailed analysis of mechanical seals in use in exploration and production activities of the oil and gas sector was undertaken. The approach of analysis was using seal design equations as mathematical models for simulating the performance of the mechanical seal. The results showed a mechanical seal with balance value of 0.5, an increased surface area between mating surfaces; provided with a flush system to enhance cooling and with seal face gap of 50 mm or less between the mating surfaces for minimal or zero leakage. The obtained results can aid the industries in seal selection and seal manufacturers in seal specifications.
