Spray Fan Flow Adjustment for Lower Water Pump Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spray fans using dynamic water sources can shorten the lifetime of the water pump due to high water pressure, as existing technologies do not effectively manage the flowrate and pressure of the liquid effectively.
Innovation Solution
Incorporating an adjustment device with a channel and adjustment holes that change cross-section, allowing the flowrate and pressure of the liquid to decrease and then increase, which reduces the pressure on the water pump and extends its service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If dynamic water source with high water pressure is used, then cooling effect is improved, but water pump lifetime is reduced
Solution Approach 1:
The adjustment device is installed upstream of the water pump to pre-regulate the water flow and pressure before they reach the pump. This preliminary action ensures that the pump only handles reduced flow rates and pressures, protecting it from high-pressure damage while still allowing the system to achieve effective cooling through the spray head assembly.
Solution Approach 2:
The adjustment device acts as an intermediary component between the dynamic water source and the water pump. It includes a flow control valve and pressure regulation mechanism that mediate the high-pressure water flow, transforming it into a suitable flow rate and pressure level for the pump while maintaining the cooling functionality.
2Productivity
If high flowrate of liquid is delivered to spray head, then cooling effect is improved, but pressure on water pump increases
Solution Approach 1:
The adjustment device pre-regulates the water flow characteristics before the water enters the pump. By installing the flow control valve and pressure regulation mechanism upstream, the system can deliver adequate flow rates to the spray head for effective cooling while the pump operates under reduced pressure conditions.
Solution Approach 2:
The adjustment device utilizes hydraulic principles to regulate water flow. The flow control valve and pressure regulation mechanism use hydraulic resistance and pressure differential to reduce the water pressure and flow rate before they reach the pump, while still maintaining sufficient flow for cooling at the spray head assembly.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustment device effectively reduces the pressure and flowrate of the liquid, minimizing the impact on the water pump and extending its service life while maintaining the cooling and humidifying functionality of the spray fan.
Implementation Method 1
the channel is provided with an adjustment hole whose cross-section changes such that the flowrate of the liquid flowing through the channel decreases and then increases
