Motor Pump Cooling Circuit Using Irrigation Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor pumps for agricultural irrigation face high energy consumption due to the need for energy-intensive cooling systems like radiators and fans to cool the combustion engine.
Innovation Solution
The motor pump incorporates a cooling circuit that uses the irrigation water, which is at a relatively low temperature, to cool the engine, eliminating the need for fans or other energy-intensive cooling systems, and includes a self-priming mechanism with a one-way valve and return channel to facilitate efficient water circulation and pump operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a radiator and fan are used to cool the combustion engine, then the engine cooling function is achieved, but the energy consumption increases
Solution Approach 1:
The patent combines the engine cooling function with the irrigation water delivery function by routing the irrigation water through the engine cooling jacket. The water serves dual purposes: irrigating the fields and cooling the engine, thereby eliminating the need for separate radiators and fans while reducing energy consumption.
Solution Approach 2:
The irrigation water is given multiple functions: it serves as both the irrigation medium for crop watering and as the cooling medium for the combustion engine. This multi-functionality approach eliminates redundant systems and reduces overall energy requirements of the motor pump.
2Temperature
If a cooling circuit with radiator and fan is implemented, then the engine can be cooled effectively, but the device complexity increases
Solution Approach 1:
The patent extracts and eliminates the radiator and fan components from the cooling system, relying instead on the natural flow of irrigation water through the engine cooling jacket to provide adequate cooling without mechanical辅助设备.
Solution Approach 2:
The cooling circuit is merged with the irrigation water delivery system, using the same water flow path for both irrigation and cooling purposes, thereby simplifying the overall device structure.
3Device complexity
If the pump operates without self-priming capability, then the structure is simpler, but the ease of operation deteriorates
Solution Approach 1:
The patent incorporates a self-priming mechanism that automatically performs the priming action before the pump begins normal operation. The one-way valve and return channel work together to fill the pump housing with water automatically, eliminating the need for manual priming operations.
Solution Approach 2:
The pump is designed to prime itself automatically using its own operational cycles. The one-way valve prevents water from escaping during the priming process, while the return channel directs water back into the pump housing, creating a self-sustaining priming mechanism that requires no external intervention.

Function Achieved in This Case
This solution reduces energy consumption by leveraging low-temperature irrigation water for engine cooling and ensures effective priming and operation of the pump, enhancing efficiency and reducing operational costs.
Implementation Method 1
