Introduction
1. Standard Overview
GB/T 32354-2015 Technical Specification for Screw Expanders (Groups) is a national standard of the People's Republic of China, mainly applicable to screw expanders (groups) with a working fluid temperature range of 120℃~300℃ and a pressure of no more than 3.0MPa, steam-water mixture, saturated steam or superheated steam. The standard specifies term definitions, guaranteed values, adjustment, operation and maintenance requirements.
2. Standard Framework Comparison
| Chapter | Content | Keywords |
|---|---|---|
| Screw ExpanderTerms and Definitions | Specify types such as back pressure type and condensing type and their application scenarios. | Terms, definitions, classifications |
| Guaranteed values | Specify the guaranteed requirements for performance indicators such as steam consumption rate and rated power. | Performance, guarantee, indicators |
| Regulation and operation | Cover speed regulation, overspeed protection and abnormal operating condition processing. | Regulation, operation, protection |
3. Background of standard formulation and analysis of technological evolution
With the increase in the demand for efficient energy utilization, screw expanders are increasingly used in waste heat recovery systems. This standard combines industry practical experience and refers to international advanced standards to clarify the technical requirements and test methods of the equipment, aiming to regulate the market and promote technological progress.
4. Implementation Suggestions
