Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centrifugation system is used for continuous gas-liquid separation, then continuous processing capability is improved, but gas-liquid separation performance becomes insufficient when powerful vacuum devices are installed
Solution Approach 1:
The impeller is divided into two distinct functional parts: a separation impeller part with centrifugal force generation capability for gas-liquid separation, and a discharge impeller part for providing discharge force. This segmentation allows each part to optimize its specific function, with the separation part handling gas removal and the discharge part maintaining continuous liquid flow, thereby resolving the contradiction between continuous processing and separation performance.
Solution Approach 2:
Different regions of the impeller are given different functional properties. The separation impeller part is designed to generate centrifugal force for separating gas from liquid, while the discharge impeller part is designed to provide discharge force for continuous liquid flow. This local differentiation of quality allows the system to achieve both continuous processing and high separation performance simultaneously.
2Ease of operation
If the impeller structure is made simple for easy cleaning, then ease of operation is improved, but durability against eccentric loads decreases
Solution Approach 1:
The impeller adopts an asymmetric structure with the suction inlet positioned closer to the bearing part than the discharge outlet. This asymmetric design allows the suction side to be simpler for easy cleaning while the discharge side can incorporate more complex features for durability. The asymmetric configuration also helps balance eccentric loads by strategically positioning the suction and discharge outlets at different locations relative to the bearing.
3Device complexity
If the suction inlet is positioned closer to the discharge outlet for compact design, then device complexity is reduced, but vulnerability to eccentric loads increases
Solution Approach 1:
The impeller employs asymmetric positioning where the suction inlet is placed closer to the bearing part rather than being symmetrically positioned relative to the discharge outlet. This asymmetric arrangement creates a more balanced structural distribution that reduces eccentric loads on the rotating shaft, thereby improving durability while maintaining compact overall dimensions.
Solution Approach 2:
Instead of positioning components along a single radial dimension for compactness, the invention utilizes the axial dimension by placing the suction inlet closer to the bearing part in the axial direction. This dimensional redistribution allows for compact radial dimensions while maintaining adequate axial spacing to reduce eccentric loads, effectively resolving the contradiction through spatial reconfiguration.
