How to determine the quality of DC water pump

To measure the performance of the brushless DC water pump, the power is relatively one of the important factors.

The technical parameters of water pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc. When evaluating the performance of a brushless DC water pump, it should first be considered whether it is suitable for the application occasion, and secondly, whether it can smoothly transport the required transmission Finally, look at the power in combination with the maximum head, maximum flow, rated head, and rated flow. Under the same conditions, the performance of the smaller power is better. The micro DC water pump has the marking measurement method of the highest head, the largest flow and the rated head. At present, the water pumps on the market are marked with the highest lift and maximum flow.

Like conventional water pumps, miniature direct current consumption is a mechanical device that transports liquid media or pressurizes liquids. It transfers the mechanical energy or other external capabilities of the pump to the conveying medium, increasing the capacity of the medium and achieving the effect of pressurized conveying. Common conveying media include water, oil, acid and alkali, emulsified liquid, suspoemulsion, liquid metal, etc. Some micro DC water pumps can also transport liquid mixtures and liquids containing suspended solids.

Micro pumps are divided into positive displacement pumps, vane pumps and other types according to different working principles. Positive displacement pumps use the change of their working volume to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps.
