Introduction
Professional interpretation of GB/T 33896—2017 Separation membrane shell cyclic pressure test method
1. Standard Overview
GB/T 33896—2017 "Separation membrane shell cyclic pressure test method" specifies the test method of separation membrane shell under cyclic pressure conditions, which is applicable to separation membrane shells with fiber as reinforcement and polymer as matrix. This standard provides detailed specifications from test principles, sample requirements, equipment configuration to result judgment.
2. Technical points of the standard
- Test medium:Tap water, ensure that the water quality meets the test requirements.
- Test temperature:Not lower than the design temperature or 65°C, whichever is higher.
- Test pressure range:Rise from the minimum pressure (20% of the design pressure or 0.27 MPa) to the design pressure and circulate.
- Monitoring instrument requirements: The relative error of the pressure sensor is ±0.3%, and the accuracy of the pressure gauge used for calibration is not less than level 0.25.
3. Standard framework comparison table
| Standard dimension | GB/T 33896—2017 | International reference standard |
|---|---|---|
| Test medium | Tap water | Deionized water/distilled water |
| Temperature range | ≥65°C or design temperature | Room temperature to 90°C |
| Pressure control | Cycling pressure frequency±3% | Cycling pressure±5% |
4. Implementation suggestions and application cases
Implementation steps:
- Equipment debugging: Ensure the normal operation of the pressure system, monitoring instruments and temperature control system.
- Sample preparation: Select samples in accordance with GB/T 30300-2013 to ensure that no liner is added.
- Cyclic test: Set the cyclic pressure frequency, start the test program, and record the results of each test.
- Data processing: Analyze leakage and damage points to evaluate product reliability.
Actual application case:
A seawater desalination equipment manufacturer used this standard to conduct a cyclic pressure test on the reverse osmosis membrane shell. The results showed that after 500 cycles under the design pressure, the sample had no leakage or damage, which met the expected indicators.
