Submersible pump selection common sense

Companies specializing in the production wells with submersible pumps products, with advanced quality assurance system, scientific management and testing methods. The company has strong technical force and rich experience in production, advanced production equipment, sophisticated, measurement, laboratory, complete with detection equipment. Technical quality of the company summary wells with submersible pump procurement of small knowledge selection, hoping to help pump pump users to choose the majority of elections.

 

Well with the submersible pump selection, look at the wells of the water, selected wells withsubmersible pump flow, each well has an economically best water, wells with submersible pump flow should be equal to or less than the bottom of the water level When the water volume is less than half of the well depth, the selected pumping volume is larger than that of the well. When the well is pumped, the well wall will collapse and affect the service life of the well. If the pumping capacity is too small, the efficiency of the well will not be fully exerted. Therefore, the best method is to conduct a pumping test wells, underground water may provide the greatest amount of water, this is done in order to select wells with submersible pump flow. Manufacturers will flow, lift, motor power, speed and so hit the pump, pump casing on the nameplate or the number marked on the specification as the standard.

 

Downhole water level descending depth and pipeline water loss pipeline to determine the actual needs of the submersible pump wells, wells with submersible pump head, is equal to the water level to the water storage tank vertical distance plus the loss of the lift. Loss of head is usually a net head of 6-9%, generally 1-2m. Well with the bottom of the submersible pump impeller into the water depth of 1-1.5m best. The total length of the downhole portion of the submersible pump tubing shall not exceed the maximum length of the well defined in the instructions of the submersible pump.

 

Underground water contains sand, more than one ten thousandth of the wells can not be installed well with submersible pumps. Because the underground water contains too much sand, such as more than 0.1% of the time, will accelerate the progress of the wear of rubber bearings, causing pump vibration, but also affect the life of the pump. Above is the submersible pump selection must consider several key factors.
