This standard is a revision of ZB172005.487≤Reciprocating piston compressor metal plane radial tangent oil dipstick. The original standard has been edited and the main technical content has not changed. This standard is the fourth part of the JB9102 series of standards for metal plane materials of reciprocating compressors. This series of standards includes the following parts: Part 1: (i.e. JB/T9102.1): Metal plane packing three-angle seal Part 2: (i.e. JB/T9102.2): Metal plane packing three-angle seal Part 3: (i.e. JB/T9102.3) Metal plane packing three-angle seal Part 4: (i.e. JB/T9102.4) Metal plane packing radial notch oil scraper ring Part 5: (i.e. JB/T912.5): Metal plane packing seal ring and oil scraper ring technical specifications Part 6: (i.e. JB/9102.6): Metal plane packing and standard from the date of implementation to replace July 3, 2005.4-87. This standard is proposed and managed by the National Technical Committee for Standardization of Reciprocating Compressors. The main drafting unit of this standard is Zongyang Compressor Factory. The main responsible persons for drafting this standard are Bai Fujing, Feng Quanke and Shen Mingyao. 15 [Scope] Machinery Industry Standards of the People's Republic of China Metal plane packing Reciprocating piston compressor Part 4: Radical cut wiper Reciprocating piston compressarmetal rectaglepackiag-Part4: Radical cut wiper iagsJB/T9102.4—1999 ZB 172 C05.4—87 This standard specifies the classification and size, matching specifications and relevant requirements of metal plane radial cut wipers (hereinafter referred to as radial cut wipers) of reciprocating piston compressors.
