The submersible pump is a kind of water-lifting machine in which the motor and the pump body are integrated and submerged underwater. It is widely used in farmland irrigation, sewage removal and drinking water delivery. Facing a large number of products with different brands and appearances, prices and performances on the market, how should we choose a submersible pump?
1. Pay attention to product information
It is necessary to choose a submersible pump with complete information such as nameplate, random accessories, and instruction manual. Check the appearance of the product before purchasing, there should be no obvious damage.
2. Use performance matching
The main performance indicators of submersible pumps are flow, head and power. For most submersible pumps of the same type, if the submersible pump products with the same power motor have the same flow rate, the head should be similar; or if the head is the same, the flow rate should be similar. The higher the flow and head parameters are, the greater the power will be. The purchaser should clearly use the flow and head, and then choose the matching power. If the selection does not match, it will not only waste resources and increase operating costs, but also cause The submersible pump has been running at super power, which affects the service life.
In addition, for different usage occasions, the corresponding submersible pump type should be selected.
3. Pay attention to energy efficiency indicators and certification marks
The national standards GB 32029-2015, GB 32030-2015, and GB 32031-2015 divide the energy efficiency of submersible pumps into grades 1, 2, and 3, respectively. The standard requires that the efficiency of the submersible pump must reach level 3, otherwise it is considered not up to standard. In the case of the same power consumption, the high-efficiency level can extract more water, that is to say, the higher the energy efficiency level, the more electricity costs can be saved. Submersible pumps are usually used continuously for a long time. The higher the energy efficiency level, the more energy-saving and the lower the cost of use.
