Recently, the spare parts for the four imported air centrifugal compressors were successfully replaced by localized ones in Tianjin Petrochemical. This solved the problem that the filter cores of centrifugal air compressors were easy to clog and the replacement of spare parts was expensive, which effectively reduced costs.
With the expansion of the expansion of the plant, the Refining Department has successively introduced four centrifugal air compressors made in the United States. After the imported equipment was put into production and operation, they started to replace the spare parts with localization. After intensive research, they boldly adopted domestically produced postcooler cores instead of expensive imported spare parts. The technical staff of the department improved the original design of the aftercooler and replaced the material of the cooler partition with the same copper material of the tube bundle. After a period of running tests, the cooling effect was not only the same as that of similar foreign products, but also Extended use cycle. With domestic spare parts, only a one-time replacement of the postcooler core can save 240,000 yuan. At the same time, the Ministry also replaced the coolers between the primary and secondary cylinders of imported centrifugal air compressors, making it possible to save 120,000 yuan in funds by replacing the coolers of a centrifugal air compressor.
