Development trend of submersible electric pump industry.

Due to the advantages of the submersible pump itself and the pump station of the submersible pump, the demand in our country will continue to increase in the future, and the following major development trends will be developed.

1. The development of large and medium-sized submersible electric pumps with large and medium-sized submersible pumps has the advantages of simplifying pump structure and saving pump station construction investment. Generally, it can reduce the cost by 40% ~ 60% and shorten the construction period by 1/2 ~ 2/3. Therefore, it will be widely used in municipal, industrial and mining, environmental protection and industrial and agricultural water supply and drainage. The future demand is expected to be large.

2. The development of multi-functional multi-purpose submersible pumps submersible electric pump in China and foreign famous submersible electric pump factory, in the form of product not enough, compared with cutting equipment such as pumps, multi-stage pump, pumping corrosive medium of submersible pumps and other production is very few, but its market demand is very big, therefore, has the very good development prospects.

3. The development of high reliability is a key part of submersible electric pump mechanical seal mechanical seal, use two single mechanical seal, this effect to the end, medium pressure can leak direction for the flow pattern, these are beneficial, but the structure is a bit complicated. Double mechanical seal in the oil chamber, on both sides of the face should use different structure, can make the medium pressure effect on the side of the face under, or just by spring force, the seals of reverse thrust is easy to make end play. Therefore, further research on structure and materials should be carried out to improve their reliability and longevity.

4. The new materials, new technology and new technology will gradually applications such as ordinary pump has been used, fluorine plastic material (F46), stainless steel lining plastic, rubber lining, spraying ceramic, etc., all these materials should be applied to the submersible electric pump as soon as possible, expand the application field of submersible pump. And the computer aided design, the auxiliary manufacturing and the auxiliary test new technology, the new technology application also is imperative. It has been proved that the application of new technology, new materials and new technology not only emancipates the labor productivity, but also ensures the stable and reliable product quality.

5. Pay attention to the appearance quality of submersible pump submersible electric pump in China and gradually enter the international market price has obvious competitive advantage in the international market, but must pay attention to improve the reliability of electric pump and life, especially to improve the quality of the appearance of the submersible electric pump, to give the user a feeling of beauty, in order to make domestic submersible pumps more to enter the international market as soon as possible.
