They often directly draw the fluid in the water inlet pipe into the water pump through the pump body and then discharge it. However, there will inevitably be impurities in the fluid in the pipeline. If the impurities directly enter the pump body, it will cause impeller wear, and seriously cause the water pump to be blocked and unusable, which leads to certain deficiencies. For this reason, we propose an improved water pump inlet flow sampling device. Utility Model Content
