Submersible pump industry development trend

Because submersible pump itself and the pump station that chooses submersible pump have a lot of advantages, accordingly, the demand of our country in the future will continue to grow, and have the following main development trend.

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

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 mechanical seal mechanical seal is a key part of submersible pump, the use of two single end face mechanical seal, so that the pressure of the media can act on the end face, the direction of leakage for internal flow, these are advantageous, but the structure is slightly complex. Install double end face mechanical seal in oil room, the end face of both sides should adopt different structure type, make the pressure of medium can act on the end face of the lower side, otherwise only rely on spring force, the reverse thrust of the sealing end face is easy to make the end face open. Therefore, the structure and material should be further studied to improve its reliability and life.

4. New materials, new technologies and new processes will be gradually applied to ordinary pumps, which have used stainless steel, fluoroplastic (F46), plastic lining, plastic lining, ceramic spraying, etc., all these materials should be applied to submersible pumps as soon as possible, to expand the application field of submersible pumps. And computer aided design, aided manufacturing and aided testing and other new technologies, the application of new technology is imperative. Facts have proved that the application of new technology, new material and new technology not only liberates labor productivity, but also guarantees 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.
