Vibration-Damping Stirrer Stand for Submersible Motor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stirrer stands for submersible motor stirrers are prone to vibrations due to irregular flows and turbulence, leading to excessive loading and costs associated with high-quality steel constructions and multi-material assemblies that fail to effectively absorb fluctuating loads.
Innovation Solution
A stirrer stand made entirely of a vibration-damping material, such as concrete or cast mineral composite, with a separate guide member for positioning during assembly that is not involved in force absorption during operation, and using elastic plates and vibration-damping bushings to minimize vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a solid steel construction is used for the stirrer stand, then strength and rigidity are improved, but vibrations are amplified and costs increase
Solution Approach 1:
The stirrer stand uses a composite construction combining steel profiles for structural framework with concrete infill for vibration damping. The concrete material absorbs vibrations while the steel provides necessary strength, resolving the contradiction between strength and vibration amplification.
2Object-affected harmful factors
If multiple materials are used for the stirrer stand, then vibration damping is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The steel profile framework and concrete infill are merged into a single integrated stirrer stand structure. The concrete is poured into the steel profile framework, creating a unified composite structure that reduces assembly complexity while maintaining vibration damping benefits.
3Ease of operation
If the guide member is fixedly connected to the stirrer stand, then positioning during assembly is improved, but force absorption capability deteriorates
Solution Approach 1:
The guide member is segmented from the main stirrer stand structure, allowing it to be separately positioned and connected. This segmentation enables the guide member to provide positioning during assembly while the main concrete structure independently absorbs operational forces without interference.
