Submersible pumps in the domestic market development

According to the analysis, since the submersible pump itself and the submersible pumping station have many advantages, the demand of our country will continue to grow in the future with the following major development trends. The development of large and medium-sized submersible pump Large and medium-sized submersible pump with simplified pump structure and save pump construction investment outstanding advantages, generally can reduce the cost of 40% to 60%, shorten the construction period 1/2 to 2/3. Therefore, it will be more and more widely used in municipal, mining, environmental protection and industrial and agricultural drainage. Expected future demand will be greater. Development of multi-purpose multi-purpose submersible pump Submersible pump in China in the form and well-known submersible pump manufacturing plant compared to the product is not enough, such as with a cutting device pump, multi-stage pump, pumping corrosive diving media Electric pumps and other production is still small, but its market demand is very large, therefore, has a good development. Developing High-Reliability Mechanical Seals Mechanical seals are a key part of submersible pumps and employ two single-ended mechanical seals so that the media pressure can act on the end face and the leak direction to inflow, which is beneficial but slightly more complicated . In the oil chamber with double-ended mechanical seal, the two sides of the end face should be of different types of structure, so that the medium pressure can be applied to the lower end of the surface, otherwise only by spring force, seal the end face of the thrust easy to open the end. Therefore, further research should be conducted on the structure and materials to improve their reliability and longevity. New materials, new technologies and new processes will be gradually applied ordinary pumps have been used stainless steel, Fluoroplastics (F46), plastic lining, rubber lining, spraying ceramics, all of these materials should be applied to the submersible pump as soon as possible to expand the submersible pump applications . The application of new technologies such as computer-aided design, auxiliary manufacturing and auxiliary testing is also imperative. Facts have proved that the application of new technologies, new materials and new technologies not only liberates labor productivity, but also ensures that product quality is stable and reliable. Submersible pump to pay attention to the appearance of quality and gradually enter the international market China's submersible pump in the international market has obvious price competitive advantage, but must pay attention to improve pump reliability and life expectancy, in particular, to improve the appearance of submersible pumps Quality, to give users a kind of beauty, so that the domestic submersible pump more and more into the international market.
