What are the advantages and disadvantages of submersible pumps?

The main structure of the submersible pump is composed of three parts: motor, water pump and water pipe. The motor and pump are connected together and completely submerged in the water. Submersible pumps according to their use is divided into water pumps and sewage pump models. Submersible sewage pump according to the form of its impeller is divided into centrifugal, axial and Francis. Submersible pumps in recent years, industrial and mining and urban water supply and drainage in the process of more and more widely used. As the use of submersible pumps continues to grow, so is the study of the advantages and disadvantages of submersible pumps. Submersible pump submersible pump advantages: 1, the motor and pump together, do not have a long drive shaft, light weight. 2, motors and pumps are dive into the water, without the need to build ground pump room. 3, because the motor is generally used for water lubrication and cooling, so maintenance costs small. Submersible pump shortcomings: 1, submersible pump structure is limited, smaller than the chemical pump lift range, so the selection of the range is greatly affected. 2, the submersible pump working part immersed in the medium, installation and maintenance difficult than the ground pump, at the same time, the fragile parts lead to the life of the machine is far lower than the chemical pump. 3, cable and seal easy to aging, leading to leakage. Submersible pumps have special requirements than ordinary pumps, submersible pumps are usually dry, semi-dry, wet, oil-filled and air-sealed motor and several other types. With the increasing use of its range, more people are concerned about the submersible pump advantages and disadvantages of concern. A product needs long-term development, must always maintain its competitiveness, the product of the advantages and disadvantages of research and exploration has been a subject.
