Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a two-stage vacuum degassing process is used, then degassing efficiency is improved, but media consumption increases and pump service life decreases
Solution Approach 1:
The degassing vessel is divided into two spatially separated chambers (first and second chambers), each capable of independent operation. This segmentation allows the system to perform single-stage or two-stage degassing by activating only the necessary chamber(s), thereby improving degassing efficiency when needed while avoiding unnecessary media consumption and pump wear during single-stage operations.
Solution Approach 2:
The system employs a controllable pump that can be selectively activated or deactivated based on process requirements. The control device dynamically adjusts pump operation to transfer liquid between chambers only when two-stage degassing is required, thereby extending pump service life by reducing unnecessary operational cycles while maintaining the capability for efficient two-stage degassing when needed.
2Manufacturing precision
If a two-stage vacuum degassing process is used, then degassing efficiency is improved, but pump service life decreases
Solution Approach 1:
The controllable pump is integrated with a control device that dynamically determines pump operation based on process requirements. The pump operates only when transferring liquid between chambers for two-stage degassing, reducing overall operational hours and extending service life, while still enabling efficient two-stage degassing when high precision is required.
Solution Approach 2:
The system design allows the same pump to serve multiple functions: transferring liquid between chambers for two-stage degassing, and potentially draining chambers. This multi-functionality reduces the need for additional pumping components and optimizes pump utilization, extending service life while maintaining degassing efficiency.
3Adaptability or versatility
If spatial separation of chambers is implemented, then process flexibility is improved, but device complexity increases
Solution Approach 1:
The degassing vessel is segmented into two spatially separated chambers that can operate independently or in combination. This segmentation provides process flexibility to select single-stage or two-stage degassing modes while using a unified vessel structure, avoiding the complexity of completely separate systems.
Solution Approach 2:
The control device merges the control logic for both chambers and the controllable pump into a single integrated system. This unified control approach manages the complexity of spatial separation by providing centralized coordination, simplifying operation while maintaining the flexibility of the two-chamber configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces media consumption and increases the service life of the circulation pump by enabling efficient degassing processes, achieving lower residual gas content and adaptable operation based on liquid requirements.
Implementation Method 1
Vacuum degassing relies on a vacuum atmosphere in the degassing tank. The water to be degassed is sprayed into the tank through nozzles, and the resulting vacuum forces the oxygen and nitrogen out of the water
Implementation Method 2
The principle of pressure degassing is based on removing the oxygen and nitrogen from the water by adding CO2

AI summary
The invention relates to a degassing system (1, 23) with a control device (17, 36), a degassing vessel (2, 24) with a first chamber (3, 25) into which liquid can be introduced, and a second chamber (4, 26) into which the liquid from the first chamber can be introduced. The first and second chambers are partially separated from each other by a partition (5, 27). A controllable pump (15, 34) is provided, which, when the pump is operated for a two-stage vacuum degassing process, pumps liquid from the first chamber to the second chamber. The control device controls the pump such that the pump is not operated for a single-stage vacuum degassing process and is operated for a two-stage vacuum degassing process.
