This standard is a revision of 2BJ72005.3-87 Reciprocating piston compressor metal flat packing, six-way sealing ring size, and the original standard has been edited and revised. The main technical content has not changed. This standard is the third part of the JBT9102 series of standards for metal flat packing for reciprocating piston compressors. The series of standards includes the following parts:
Part 1: (JB/T91021): Zhou Pingying material - oblique mouth travel seal Part 2: (JR9102.2): Huiping flat material oblique mouth oil scraper ring Part 3: (ie JRT 9102.3): Metallic surface packing - six-piece seal Part 4: (ie JB/T9102.4): Metallic flat bevel radial notch oil scraper Part 5: (ie JB/T9102.5: Rectangular piston compressor radial notch oil scraper Part 6: (ie JB/T9102.6) Technical conditions for flat packing seals and oil scrapers This standard replaces 2B372005.3-87 from the date of implementation. This standard is proposed and approved by the National Technical Committee for Compressor Standardization. The main drafting unit of this standard: Chengyang Compressor Factory The main responsible drafters of this standard: Bai Zhoujing, Feng Quanke, Shen Mingyao.
