Pump Assembly with Automatic Temperature-Dependent Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumps used in bodies of water subject to biological influences require manual speed adjustment based on temperature changes, leading to inefficient energy consumption as they often operate at full load year-round due to lack of automatic temperature-dependent control.
Innovation Solution
A pump arrangement with integrated temperature control electronics, data memory, and software that automatically adjusts pump speed based on specified temperature limits, ensuring optimal operation and energy savings by increasing speed with rising temperatures and maintaining higher speeds at low temperatures for enhanced gas exchange and freezing protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual speed adjustment is used, then the pump can be operated at full load for convenience, but energy consumption increases unnecessarily
Solution Approach 1:
The pump system performs self-service through automatic temperature-dependent speed control. The controller continuously monitors water temperature and autonomously adjusts pump speed without manual intervention, eliminating the need for constant observation and manual adjustment while optimizing energy consumption based on actual biological activity requirements
Solution Approach 2:
The system implements feedback control by continuously measuring water temperature and using this information to automatically adjust pump speed. The controller receives temperature feedback and modulates the pump motor speed accordingly, creating a closed-loop control system that optimizes energy consumption while maintaining adequate circulation
2Use of energy by moving object
If pump speed is reduced at low temperatures, then energy is saved, but gas exchange and oxygenation are compromised
Solution Approach 1:
The system dynamically changes the pump operating parameters (speed) based on temperature conditions. At low temperatures where biological oxygen consumption is reduced, the controller maintains adequate but lower pump speeds, optimizing the balance between energy consumption and sufficient gas exchange requirements
3Use of energy by moving object
If automatic temperature-dependent control is implemented, then energy is saved through optimized speed regulation, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical speed adjustment with electronic control. The controller uses electronic components to sense temperature and automatically regulate motor speed, substituting complex manual monitoring and adjustment mechanisms with a simpler automated electronic control system
