Deep well submersible pumps on the market type is very much, only from the manual to see very good distinction between product characteristics. Then the customer how to choose products in the product selection? The next will be summarized by the predecessors of some of the deep-well pump selection experience to share product selection should pay attention to.
How to choose stainless steel deep well submersible pump
1, suggesting that well water sediment content of more than one ten thousandth of the motor shaft:
Should not be installed using the deep well pump. Because the well water sediment concentration is too large, such as more than 0.1%, will accelerate the wear of rubber bearings, causing pump vibration, shorten the pump life.
2, according to the decline in well water level and water pipeline head loss:
Determine the actual needs of the pump shaft, that is, the pump head, which is equal to the water level to the pond water surface of the vertical distance (net head) plus the loss of head. Loss of head is usually a net head of 6 - 9%, generally 1--2m. The bottom of the pump impeller into the water depth of 1 - 1.5m is appropriate. The total length of the downhole portion of the pump pipe shall not exceed the maximum length of the well entered in the pump instructions.

3, according to the well of the water:
Select the pump flow rate. Each well has an economically optimal amount of effluent, and the pump flow rate should be equal to or less than the well water level drops to half the well water depth. When the pumping volume is greater than the amount of water from the well, it will cause the collapse of the shaft wall, affecting the service life of the well; if the pumping capacity is too small, the benefits of the well will not be brought into full play. Therefore, the best way is to carry out pumping tests on wells to wells may provide the largest amount of water for the selected well pump flow basis. The pump flow rate shall be based on the number marked on the type or specification of the manufacturer.
4, according to well diameter, water quality of the initial pump:
Different types of pump diameter of the well have certain requirements, the maximum pump size is less than the diameter 25 - 50mm. If the wellbore is skewed, the maximum dimensions of the pump should be smaller. In short, the pump part of the well can not be close to the wall to prevent damage to the pump vibration.
Stainless steel deep well submersible pump is suitable for deep water wells, hot water wells and marine extraction, but also can be used for irrigation and plateau mountain areas of human and livestock water, factories, railways, mines for water supply and drainage. In China, stainless steel deep well submersible pump after years of development, its more suitable for people's production and life. Further research on it is needed by the times. Only the relevant work done more detailed, its future development can be more smooth.
