1. Select standardized water pump

Standardized water pumps are the latest models of pumps that are formulated and implemented in accordance with the requirements of ISO. Its main features are small size, light weight, excellent performance, easy operation, long life, low energy consumption. It represents the latest trend of the current pump industry.

When users choose the pump, it is best to go to the sales point recognized by the agricultural machinery department. We must recognize the manufacturer. It is recommended to give priority to buying a water -filled diving pump, and see the card number and product quality qualification certificate. Do not buy "three -no" (that is, no manufacturer, no production date, no production permit) products, otherwise there will be problems, and users will be helpless.

2. Determine a single -phase pump or three -phase pump according to the local power supply.

3. Select the pump.

The so -called raising refers to the need to raise the journey, not the height of the water lifting. This is particularly important to choose the pump. The pump is about 1.15 to 1.20 times at the height of the water lifting. For example, the vertical height of a water source to the water is 20, and the required journey is about 23 to 24.

When choosing a pump, the raising of the pump nameplate is best to get close to the need to raise the journey. In this case, the pump is the highest efficiency and it will be more economical. However, it is not necessary to be absolutely equal. Generally, as long as the deviation does not exceed 20 % of the meter, the pump can work without energy saving.

4. How much is the name of the nameplate?

Choosing a pump that is far less than the required raising is often not able to meet the user's wishes. Even if it can pump the water, the amount of water will be pitiful, and it will even become a "idle pump" that is useless. Essence

Is the higher the pump you buy, the higher the better? actually not. The pump of the high -row is used to low, and the traffic will occur too much, resulting in overloading of the motor. If it runs for a long time, the temperature of the motor rises, and the winding layer of the winding will gradually age and even burn the motor.
