Oil separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing oil separators with curved portions in inflow pipes require increased space for installation, necessitating a reduction in size while maintaining effective oil separation efficiency.
Innovation Solution
The oil separator design integrates the curved portion of the inflow pipe with the separator body, forming a common peripheral wall, and includes an oil draining hole to discharge separated oil, allowing for a compact integral structure that reduces the overall size of the separator and compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the inflow pipe includes a curved portion for centrifugal separation, then oil separation efficiency is improved, but the installation space and overall size of the oil separator increase
Solution Approach 1:
The curved portion of the inflow pipe is merged with the separator body by making their peripheral walls common to each other. This integration eliminates the need for separate curved portion structures, achieving effective oil separation through centrifugal force while reducing the overall installation space and size of the oil separator.
2Ease of operation
If the separator body and inflow pipe are made as separate components, then assembly and maintenance are easier, but the overall size and complexity of the oil separator increases
Solution Approach 1:
The separator body and inflow pipe are designed with common peripheral walls, integrating what could be separate components into a unified structure. This reduces structural complexity and the number of parts, while the design maintains ease of assembly and maintenance through straightforward integration.
3Manufacturing precision
If the curved portion has a larger radius for better centrifugal separation, then oil separation performance is improved, but the device size increases
Solution Approach 1:
The curved portion is integrated with the separator body through common peripheral walls, allowing the centrifugal separation function to be achieved within the existing separator geometry. This eliminates the need for additional space that would be required if the curved portion were a separate, larger-radius component, thus maintaining separation performance while reducing device size.
