Sealing Performance Test Equipment with Radial Fixed Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing testing process for sealing rings is complex and inefficient, requiring multiple pieces of equipment to assess sealing performance across various pressure and temperature conditions, which is not adequately addressed by current technologies.
Innovation Solution
An equipment for sealing-performance testing that includes a housing with a fixed mechanism and detection part, where a central rod and fixed blocks are used to form test and detection cavities around the sealing ring, allowing for the detection of test fluid parameters to determine sealing performance, accommodating different ring sizes and compression levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple pieces of test equipment are used to test sealing performance under various pressure and temperature conditions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple test equipment functions into a single integrated testing device. The housing contains both the test cavity for pressure/temperature testing and the detection cavity for fluid detection, eliminating the need for separate equipment and simplifying the overall testing system while maintaining comprehensive sealing performance evaluation capabilities
Solution Approach 2:
The testing device is designed with multi-functionality to perform various sealing performance tests under different pressure and temperature conditions within a single device. The fixed mechanism can accommodate different sealing ring sizes and the integrated design allows both pressure application and fluid detection functions to coexist in one system
2Measurement precision
If multiple pieces of test equipment are used to test sealing performance, then measurement precision is improved, but productivity decreases
Solution Approach 1:
By merging multiple testing functions into one integrated device, the patent enables simultaneous or sequential testing operations without the need to move samples between different equipment, thereby improving testing efficiency and productivity while maintaining comprehensive measurement precision
Solution Approach 2:
The device is pre-configured with both test and detection cavities along with the fixed mechanism, allowing testing to begin immediately after sample installation without requiring setup or transfer between equipment, thus improving productivity
3Adaptability or versatility
If a fixed mechanism with movable fixed blocks is used to form test and detection cavities, then adaptability is improved, but device complexity increases
Solution Approach 1:
The fixed blocks are designed to be movable rather than fixed, allowing them to adjust their positions to accommodate different sealing ring sizes and compression requirements. This dynamic adjustment capability provides versatility while maintaining a relatively simple overall structure compared to having multiple fixed configurations
