Submersible Pump Reversible Plate for Solid Particle Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing submersible pumps are either dedicated to evacuating liquids laden with solid particles or clear liquids, but not both effectively, and previous solutions for convertibility, such as the bayonet system, are prone to deterioration and operational issues.
Innovation Solution
A submersible pump with a reversible design featuring a plate that can be mounted in two configurations, one for evacuating liquids with solid particles and another for clear liquids, utilizing a paddle wheel and adjustable cavities to accommodate different liquid sizes, allowing for efficient evacuation of both types without the need for multiple pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pump inlet port is positioned higher to evacuate solid particles, then particle evacuation capability is improved, but residual liquid height increases
Solution Approach 1:
The inlet structure is segmented into multiple openings at different heights, allowing the pump to handle both large particles (through higher openings) and minimize residual liquid (through lower openings), thus resolving the contradiction between particle evacuation capability and residual liquid height
Solution Approach 2:
The pump inlet structure incorporates adjustable elements that can be dynamically repositioned to optimize the balance between particle evacuation and residual liquid minimization based on operational requirements
2Length of stationary object
If the pump is designed for clear liquid evacuation with lower inlet, then residual liquid height is reduced, but solid particle evacuation capability is lost
Solution Approach 1:
The pump inlet is designed with multiple openings and adjustable components that enable the same pump structure to function effectively for both clear liquid evacuation (using lower openings) and solid particle evacuation (using higher openings), achieving universality across different operational scenarios
3Adaptability or versatility
If a bayonet system is used for pump configuration conversion, then convertibility between configurations is achieved, but reliability deteriorates due to loosening and deterioration
Solution Approach 1:
The bayonet connection system is extracted and replaced with a more reliable connection mechanism that maintains configuration convertibility while eliminating the loosening and deterioration problems inherent in bayonet systems
Solution Approach 2:
The new connection system incorporates pre-designed anti-loosening features and protective elements that prevent connection deterioration before it occurs, ensuring long-term reliability while maintaining convertibility
