Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Submersible motor pumps face premature wear, reduced lifespan, and increased energy consumption due to sediment and impurity accumulation on their components, leading to operational difficulties and high maintenance costs, especially when handling dirty water with high sediment loads.
Innovation Solution
A cleaning system for submersible motor pumps featuring a series of valves and sensors in three zones (impellers, motor, and suction filter) that allows for continuous maintenance by injecting clean water and cleaning compounds, and expelling dirty water and sediments, enabling effective removal of adhered impurities without disassembly, using external or attached pumps for pressure and flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If submersible motor pumps operate continuously in dirty water with high sediment loads, then productivity is maintained, but sediment and impurity accumulation on components causes premature wear and reduced lifespan
Solution Approach 1:
The cleaning system performs preliminary actions by continuously injecting cleaning compounds and water through valves before sediment accumulation reaches critical levels. The system proactively prevents wear and obstruction by maintaining constant cleaning flow through the pump components, thereby extending pump lifespan while allowing continuous operation in dirty water
Solution Approach 2:
The cleaning system operates continuously alongside the pump, with cleaning compounds and water constantly flowing through the pump components via injection valves and pipes. This continuous cleaning action ensures that sediment removal is an ongoing process rather than a periodic maintenance task, allowing the pump to maintain reliability during continuous productivity operations
2Productivity
If submersible motor pumps handle dirty water with high sediment loads, then productivity is maintained, but energy consumption increases due to operational difficulties
Solution Approach 1:
The cleaning system continuously removes sediment and impurities from the pump components through constant injection of cleaning compounds and water. By maintaining continuous cleaning flow through the impellers and internal passages, the system prevents energy-wasting obstructions and wear, allowing the pump to operate efficiently while handling dirty water at full productivity levels
3Reliability
If traditional cleaning methods are used requiring disassembly, then thorough cleaning is achieved, but loss of time and increased maintenance costs occur
Solution Approach 1:
The pump performs self-cleaning through the integrated cleaning system that continuously injects cleaning compounds and water through valves and pipes directly into the pump components. The system cleans itself during operation without requiring external disassembly or manual intervention, thereby maintaining thorough cleaning effectiveness while eliminating maintenance time loss
Solution Approach 2:
The cleaning system performs preliminary cleaning actions continuously during pump operation, preventing sediment accumulation before it reaches levels requiring disassembly. By proactively maintaining clean components through constant cleaning flow, the system eliminates the need for time-consuming periodic disassembly and manual cleaning
4Adaptability or versatility
If submersible motor pumps operate in dirty water conditions, then adaptability is improved, but maintenance costs increase due to premature wear and obstruction
Solution Approach 1:
The cleaning system continuously injects cleaning compounds and water through valves and pipes to remove sediment and impurities from pump components. This continuous cleaning action prevents wear and obstruction that would otherwise increase maintenance costs, allowing the pump to maintain adaptability to handle various water qualities while keeping maintenance expenses low

AI summary
The invention relates to a cleaning system for submersible motor pumps (3) covered with suction sleeves and disposed horizontally or vertically. The system comprises sensors and a series of ducts for injecting water and cleaning compounds, disposed in the suction sleeve (4) of the pump in three zones, namely: an impeller zone A, a motor zone B and a central suction filter (16) zone C. The system can be applied to two submersible pumps in parallel, each pump driving the injection liquids of the other. The used method comprises five steps: a first step comprising the consecutive washing of zones A, B and C; a second step comprising the injection of cleaning compounds; a third soaking step; a fourth step comprising the consecutive heavy-duty washing of zones A, B and C; and a fifth step corresponding to the end of the method.
