This standard is a revision of the recommended chemical industry standard HG/T2098—1991 "Mechanical seal series and operation parameters for process tanks". This standard will replace HG/T2098—1991 from the date of implementation. This standard was proposed by the Policy and Regulations Department of the former State Administration of Petroleum and Chemical Industry. This standard is under the jurisdiction of the Chemical Industry Special Seal Standardization Technical Committee. The drafting units of this standard are: Beijing University of Chemical Technology, Kunshan Kettle Mechanical Seal Factory, Shazhou Institute of Technology Mechanical Seal General Factory, Zhejiang Changcheng Reducer Co., Ltd., Wenzhou Jiangnan Mechanical Seal Factory. The main drafters of this standard are: Li Jihe, Wu Jianming, Wang Liming, Sheng Jianhua, Yu Peiqing. Chemical Industry Standard of the People's Republic of China
Mechanical seal series and operation parameters for process tanks
Mechanical seal series and operation parameters for process tanks1Scope
This standard specifies the series and main parameters of mechanical seals for process tanks. HG/T2098—2001
Replaces HG/T2098—1991
This standard applies to mechanical seals for steel reaction tank stirring shafts and similar vertical rotating shafts. Its working parameters are: the pressure of the medium in the reactor is 1.33×10-5 (absolute pressure) ~ 6.3MPa, the temperature of the medium is not more than 350℃ (when the temperature of the medium in the reactor is high, refer to HG/T2122 to add auxiliary measures); the outer diameter of the stirring shaft (or sleeve) is 30~220mm; the speed is not more than 2m/s: the medium is a variety of fluids except strong oxidizing acids and high-concentration alkalis.
