Introduction
1. Standard Overview
GB/T 13929-2024 "Test Methods for Water Ring Vacuum Pumps and Water Ring Compressors" is an important national standard used to regulate the test process and measurement methods of water ring vacuum pumps and water ring compressors. Compared with the 2010 version, this standard has been revised in many aspects such as term definitions, test device requirements and uncertainty assessment.
2. Comparison of standard frameworks
| Chapter Contents | Requirements of the 2010 Edition | Revised in the 2024 Edition |
|---|---|---|
| Terms and Definitions | Not clearly specified | Definitions of test instrument accuracy and random uncertainty were added |
| Test Device | Connection method shown in Figure 1 is adopted | Requirements for measuring points of two-stage pumps and provisions for vibration and noise measurement points are added |
| Uncertainty Assessment | Random uncertainty is not involved | Detailed assessment methods for random and systematic uncertainties are added |
3. Background of Standard Formulation and Analysis of Technology Evolution
With the widespread application of vacuum technology in the industrial field, the performance requirements for water ring vacuum pumps and compressors are increasing. The original standard GB/T 13929-2010 can no longer fully meet the development needs of modern measurement technology. This revision fully considers industry feedback and technological progress, aiming to improve the scientificity and operability of the test method.
4. Implementation Suggestions
Case Study: Application in a Certain Enterprise Laboratory
In actual application, it is recommended that enterprises pay attention to the following points when implementing this standard:
- Selection and calibration of instruments: Ensure that the flowmeters, pressure gauges and other equipment used meet the measurement uncertainty requirements specified in Table 1.
- Control of test conditions: Strictly control the ambient temperature and humidity to ensure the accuracy of the test data.
- Measurement data recording and analysis: Record at least two repeated results according to the standard requirements, and make necessary conversions to meet the performance indicators under the specified conditions.
