Development trend of submersible pump industry

As the submersible pump itself and the use of submersible pump pump station has many advantages, therefore, the future of China's demand will continue to grow, and the following main trends.
1. Development of large and medium-sized submersible pumps Large and medium-sized submersible pumps with simplified pump structure and saving pump station construction investment outstanding advantages, generally reduce the cost of 40% to 60%, shortening the duration of 1/2 ~ 2/3. Therefore, it will be in the municipal, industrial and mining, environmental protection and industrial and agricultural drainage and other aspects of more and more widely used. Expected future demand will be larger.
2. Development of multi-purpose multi-purpose submersible pump China's submersible pump in the form of foreign famous submersible pump production plant compared to the product is not enough, such as with a cutting device pump, multi-stage pump, pumping corrosive media Submersible pumps and other production is still very small, but its market demand is very large, therefore, has a very good development prospects.
3. Development of high reliability mechanical seal Mechanical seal is a key part of the submersible pump, the use of two single-end mechanical seal, so that the pressure of the medium can be applied to the end, the leakage direction for the flow, these are favorable, but the structure Slightly complicated In the oil chamber with double-ended mechanical seal, both sides of the end surface should be used in different structural types, so that the medium's pressure can be applied to the lower side of the face, or rely on spring force, sealing the end of the anti-thrust easy to open the end. Therefore, further research should be carried out on the structure and materials to improve its reliability and longevity.
4. New materials, new technology and other new technology will gradually use ordinary pump has been used stainless steel, fluorine plastic (F46), lined with plastic, rubber, ceramic, etc., all of these materials should be applied to the submersible pump as soon as possible to expand the submersible pump Application areas. And computer-aided design, auxiliary manufacturing and auxiliary testing and other new technologies, new technology applications are imperative. Facts have proved that new technology, new materials, new technology applications, not only the liberation of labor productivity, but also to ensure product quality is stable and reliable.
5. Attention to the appearance of submersible pump quality and gradually enter the international market China's submersible pump in the international market has a clear price competitive advantage, but must pay attention to improve the reliability and life of the pump, in particular, to improve the submersible pump The appearance of quality, give users a sense of beauty, so that domestic diving pump as soon as possible into the international market.
