Screw Compressor Liquid Supply Mechanism with Intersecting Branch Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional liquid supply mechanism for screw compressors increases manufacturing costs and risks of lubricant leakage due to the large number of blind holes and sealing members required, especially when multiple liquid supply sections are present.
Innovation Solution
A liquid supply mechanism with multiple liquid supply sections featuring branch paths whose central axes intersect, directly connected to a common supply path, reducing the number of processing steps and sealing members, and optimizing flow resistance to ensure uniform lubricant distribution and atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple liquid supply sections are added to the compressor, then the lubricant supply coverage is improved, but the number of blind holes and sealing members increases, leading to higher manufacturing costs and increased leakage risk
Solution Approach 1:
Multiple liquid supply sections are merged into a single integrated structure where multiple branch paths diverge from one common supply path. This combines what would traditionally be separate supply sections into a unified system, reducing the number of blind holes and sealing members while maintaining multiple supply points for improved lubricant coverage
Solution Approach 2:
The single supply path is segmented into multiple branch paths that diverge to different locations. This segmentation allows the lubricant to be distributed to multiple areas through a unified structure, achieving wide supply coverage without requiring multiple independent supply sections
2Reliability
If multiple blind holes are created for liquid supply, then the lubricant distribution is improved, but the number of processing steps increases, leading to higher manufacturing costs
Solution Approach 1:
Multiple blind holes are merged into a single supply path structure with branch paths. Instead of creating multiple separate blind holes that require individual processing, the invention uses one integrated supply path that can be formed in fewer processing steps while still providing multiple outlet points for lubricant distribution
3Reliability
If multiple sealing members are added to seal the liquid supply paths, then the leakage prevention is improved, but the number of joints and sealing members increases, creating more potential leakage points
Solution Approach 1:
Multiple sealing locations are merged into a reduced number of sealing points by consolidating the supply paths. The single supply path with branch paths requires fewer joints and sealing members compared to multiple independent supply sections, thereby reducing the number of potential leakage points while maintaining effective sealing
