Standard specifications
Project judgments and procurement conclusions
The intermediate air duct of a bi-track thermal pump is suitable for air pressure testing; the squeeze pump and the non-ventilating node are commonly used in vacuum boxes or other project-approved methods; the detachment and cutting are destructive samples used to assess the strength and degradation patterns of the pump. No single method can replace the full CQA, and the frequency, pressure, pressure, time and determination values of the pump must be performed in accordance with the contract specification.
Standard specifications
Key parameters and quick judgement tables
| The method | Applied Objects | The main findings |
|---|---|---|
| Air pressure testing | Two-track rail | Continuity and channel leaks |
| The empty box | Pressure pumps/supplements | Local air leakage points |
| The Exploitation | Hot welding sample | Interface separation and intensity |
| Cutting experiments | Hot welding sample | The whole load of the pump |
Standard specifications
Acceptance points and common risks
- Only record the passThe original pressure, time, sample size and disruption patterns should also be preserved.
- Not reviewed after repairThe process itself may produce new marginal defects.
- Frequency of samplingThe project should be in compliance with the CQA plan and cannot be arbitrarily reduced due to compression over time.
