Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vortex-eliminating devices for pump stations are costly, inflexible, and inefficient, leading to uneven flow distribution, cavitation, and noise/vibration issues in water pumps due to unstable vortexes, with maintenance costs and labor consumption being high.
Innovation Solution
A floating counter-rotating vortex-eliminating device comprising a floating driving disc, counter-rotating gear box, reverse-rotating disc, plane bearing, and balance weight, which moves to counteract vortexes by rotating in the same direction as the vortex, using a counter-rotating mechanism to stabilize the flow and prevent vortex development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floating net vortex-eliminating method is used, then vortexes can be eliminated in a targeted manner, but hydraulic loss increases and vortexes smaller than the meshes may be generated
Solution Approach 1:
The invention extracts and eliminates only the harmful vortex component from the water flow while allowing the main flow to pass through the intake bay freely. The vortex elimination device specifically targets and removes the rotational flow component without creating significant resistance to the primary water flow, thus eliminating vortices while minimizing hydraulic loss.
Solution Approach 2:
The vortex elimination device is positioned specifically at the vortex generation location in the intake bay, creating a localized solution rather than a universal barrier. The device structure and mesh configuration are optimized for the specific vortex conditions at that location, effectively eliminating vortices while maintaining open flow paths elsewhere that minimize hydraulic loss.
2Reliability
If a floating net vortex-eliminating method is used, then vortexes can be eliminated, but when water level changes the floating net requires remounting which consumes time and labor
Solution Approach 1:
The vortex elimination device is designed as a floating structure that dynamically adapts to changing water levels. The device follows the water level fluctuations automatically, maintaining its functional position without requiring manual intervention. This dynamic design eliminates the need for remounting when water levels change, saving time and labor while continuously providing vortex elimination effectiveness.
3Reliability
If a floating vortex-eliminating device with contact with water surface is used, then vortex formation is prevented, but construction and maintenance costs increase and flexibility decreases
Solution Approach 1:
The floating vortex elimination device is divided into multiple modular segments or components that can be independently manufactured, assembled, and maintained. This segmentation reduces construction complexity and costs while improving maintainability, as individual modules can be replaced or repaired without affecting the entire system. The modular design also provides flexibility in deployment and adaptation to different water level conditions.
