How to use impeller to change pump lift?
Once the water pump factory, it is not easy to change, but also can if you change it, you said, just don't know what kind of what kind of impeller pumps, self-priming pump, like home, lift can reach 10 meters above, if you want to change it to the impeller pump head and seal a change, change, if the pack is a big wheel, the power can not keep up, the motor will be hot, burn out the motor. If it is a household head pump, it is more difficult to change the impeller.
In addition, the theoretical head increases with the width and diameter of the blade, but it is not proportional to the width of the blade. This can be derived from the theoretical head equation, the specific equation, relevant data should be here, it is too difficult to fight, I hope to help you
The impeller blade is divided into pre curved blade radial blade and blade, can obtain the maximum theoretical head with curved blade, but the project is generally used after the curved blade, although its theoretical lift is smallest, but after the curved blade, the static head of the share of the largest, the most favorable economic indicators.
The general pumps are centrifugal pumpsAccording to the theoretical relationship of the centrifugal pump head, we can see that the lift is related to the speed of the impeller and the shape of the blade. Of course, there are other factors.
