This standard is a revision of 2BJ76011-89 (Technical conditions for non-moisture reciprocating high-pressure oxygen compressors). Compared with ZB16011-89, the main technical contents of this standard have been changed as follows: 1. The original standard for noise assessment was sound pressure level, which is now changed to sound power level. Therefore, the test method and reference standards should be changed accordingly. 1. Cancel the cleanliness index.
1. Reliability requirement index: Change the annual reliability effective seat to the annual average availability. This standard replaces 76011-9 from the date of implementation. This standard is proposed and managed by the Technical Committee for Standardization of Gas Separation and Liquefaction Equipment. The drafting unit of this standard is Hangzhou Gas Making Machinery Group Co., Ltd. The main drafters of this standard are Peng Zhenkang and Yu Yongle. This standard was first issued in February 1989.
