How to select a well submersible pump?
- Apr 10, 2018 -

Wells with submersible pump with the high-speed development of science and technology in our country, the competition also received a lot of ascension, such products using site is more special, customers need to pay attention to when product choice place has a lot of, such as head, flow, etc. The product is not only the product itself, but also the product needs to meet his bole. Only in this way, can the product develop its maximum value. So what should be the submersible pump selection?

Next, we will detail the selection of the well submersible pump:

1. Pump type according to well diameter and water quality. Different types of pumps have a certain requirement on the diameter of borehole diameter, and the pump body cannot be close to the inner wall of the well, so as to prevent the pump vibration from damaging the well.

2. The well water is more than one part of the machine well, which is not suitable for the installation of deep well pump. Because the well water content is too large, cause the pump vibration, shorten the pump life.

3. Select the flow of the well pump according to the water output of the well. Each well has an economically optimal amount of water, and the flow of the pump should be equal to or less than the amount of water that falls to the depth of the well. The well may provide the maximum amount of water for the selected well pump flow. The water pump flow rate shall be subject to the number marked on the label model or manual.

4, according to the drawdown of depth and the water pipe head loss, determine the head of well pump actual need, the well pump lift, it is equal to the water level to the vertical distance out of the pool water net (lift) and head loss. The loss head is usually 6-9% of the net lift, usually 1-2m. The total length of the underground part of the water pump should not exceed the maximum length specified in the pump specification.

The quality of a class of products focuses on the characteristics of the product, but it is also important in product selection. With the increasing use of submersible pump in China, more research on its selection can not only improve product competitiveness but also improve product promotion rate. There is a lot more work to be done in order to have better development prospects.
