Submersible Pressure Pump Adapter for Switching Suction Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional submersible pressure pumps face challenges in stable operation on their side for floating extraction and complex changes between suction situations, requiring partial disassembly and inadequate buoyancy in float switches.
Innovation Solution
A submersible pressure pump design with an adapter for tool-free switching between suction situations and an improved external float switch with increased buoyancy, allowing for stable operation in both upright and floating positions without disassembly, using a pump housing with a large-area inlet and a single bottom inlet, and a liquid pump with a level-dependent on/off switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the submersible pressure pump is laid on its side for floating extraction, then liquid can be sucked in close to the surface through a hose, but the pump rolls back and forth and does not lie securely
Solution Approach 1:
The patent introduces a stabilizing element (counterweight) that compensates for the pump's instability when laid on its side. This counterweight creates a stabilizing moment that prevents the pump from rolling back and forth, enabling secure floating extraction operation while maintaining the desired adaptability
2Adaptability or versatility
If the submersible pressure pump is partially disassembled to install a hose for floating extraction, then switching between suction situations becomes possible, but the switching process becomes complex
Solution Approach 1:
The patent introduces an adapter as an intermediary component that simplifies the switching process. Instead of partially disassembling the pump to install a hose, the adapter provides a simple interface that enables floating extraction mode while maintaining ease of operation and reducing switching complexity
3Volume of moving object
If the float switch has low buoyancy, then the pump housing can be compact, but the float switch cannot reliably detect sufficient liquid level
Solution Approach 1:
The patent applies the counterweight principle to the float switch by providing it with sufficient buoyancy (counteracting its weight). This ensures the float switch can reliably rise to detect the liquid level and trigger the on/off switch, maintaining detection reliability while keeping the overall pump design compact
