ANTI-FRICTIONAL MATERIALS IN SEALING ELEMENTS OF OIL FIELD COMPRESSORS
The article considers usage of 7V-2A, F4-K20 and F4-G40 (7B-2A, Ф4-К20 и Ф4-Г40) graphite-plastic materials in friction joints of 2SG-50 (2СГ-50) oil field compressors. Correlation dependences of wear-out process of sealing elements on operational regime are determined. The results allow to recommend the above-mentioned materials for usage in piston and gland joints of oil and gas compressors
