How to choose pump head

Select the method of water pump meeting the head requirements

1 pump head selection

The so-called head refers to the required head, not the water lifting height, which is particularly important for the selection of water pumps. Water pump

The lift is about 115 ~ 120 times of the lifting height. If the vertical height from a certain water source to the water consuming place is 20m, it needs

The lift is about 23 ~ 24 meters. When selecting the water pump, it is better to make the head on the nameplate of the water pump close to the required head

In this case, the efficiency of the water pump is the highest and the use will be more economical. However, it is not necessarily required to be absolutely equal. As long as the general deviation is no more than 20%, the water pump can work under the condition of energy saving.

2. How big is the nameplate lift? Choose a pump with a far smaller lift on the nameplate. If the required lift is dry, it will often not be full

Meet the user's wishes, even if you can pump water, the water volume will be pitifully small, and even become a useless machine

"Idle pump". Is the higher the pump head, the better? It's not. The pump with high head is dry and low head is convenient

There will be excessive flow, resulting in motor overload. If the motor runs for a long time, the motor temperature will rise, and the winding insulation will gradually age, or even burn the motor.

3、 Select the pump with appropriate flow. Generally, the flow of the pump, i.e. the water output, should not be too large, otherwise, it will increase

The cost of purchasing water pumps. Specific problems should be analyzed. For example, the flow of self-priming water pump for users' own draught should be reduced

Try to choose smaller ones: for example, the submersible pump used by users for irrigation, you can appropriately choose the one with larger flow.
