The Impact Of Replacing The Small Impeller On The Water Flow Rate Of A Submersible Pump

Aug 29, 2024

1, The function and precautions of replacing the small impeller
Small impeller is one of the important components of submersible pumps, mainly used for pressurization and conveying water flow. During the use of submersible pumps, if insufficient water flow or excessive noise is found, it is likely that there is a problem with the small impeller. At this point, it is necessary to replace the small impeller of the submersible pump.
When replacing the small impeller, the following points should be noted:
1. Clean the old small impeller and impeller groove, remove dirt and foreign objects;
2. Pay attention to the direction of the small impeller and do not invert it;
3. Ensure that the new small impeller used is identical to the original accessories.
2, Will the replacement affect the water supply
The most obvious change after replacing the impeller is the change in the water volume of the submersible pump. According to actual testing and customer feedback, the change in water volume on the submersible pump after replacing the impeller is not significant, usually only within 10%.
The impact of replacing the small impeller on the water flow may be influenced by the following factors: the model and power of the submersible pump, the degree of failure before replacement, and the quality of the small impeller after replacement.
However, it should be noted that if there is a significant decrease in the water supply after replacement, it is generally due to the following reasons:
1. There are installation problems when replacing the small impeller, such as reverse installation of the small impeller;
2. After replacement, there are problems with the small impeller, such as poor quality, blade deformation, excessive wear, etc.
3, Summary
After replacing the impeller of a submersible pump, the degree of impact on the water flow is affected by multiple factors, but it is usually limited. If problems such as a decrease in water supply still occur after replacement, it is necessary to check the installation method and quality of the small impeller for replacement. Meanwhile, the comparison of water intake before and after replacement can also be verified through actual testing to better understand the effect of replacing the small impeller.
