With the popularization of the well submersible pump and the expansion of the application field, the well submersible pump must meet the requirements of more different environments. With the feedback of market data, using CAD and CFD computer aided design and manufacturing and auxiliary test software, and fluorine plastic, plastic lining, lining material, glue spraying ceramics and new technology application, the submersible pump is gradually to the high efficiency, energy saving and environment protection is the direction of development. The following is as follows:
(1) technological innovation will bring new technology and new material to use in the production of well submersible pump. For example, the traditional casting process has developed to a more advanced stainless steel stamping and welding process. The core components of multistage pump stainless steel stamping and welding of stainless steel plate by stamping, has high reliability, good sealing performance, higher precision, and the hydraulic performance of pump efficiency is better than casting production wells with submersible pumps, stainless steel stamping and welding process is well used in the future development trend of submersible pump.
(two) the design will develop in the direction of more efficient, energy saving and environmental protection. For example, the oil filled motor design is designed for the more environmentally friendly water filled motor. The medium filled with oil filled submersible motor is mechanical oil, and the medium filled with water filled submersible motor is water. One of its advantages is zero pollution of water body and more environmental protection. In addition, as the application of frequency conversion technology in the design of motor is gradually popularized, the future well submersible pump will be more efficient and energy saving.
(three) integrated design is developing towards the direction of removable modularization design, that is, modular combination of components such as motor and pump body, which is convenient for dismantling and replacing damaged parts, so as to extend the service life and reduce the cost of water pumps.
