The submersible pump itself and the pump station of submersible pump have many advantages. Therefore, the demand of our country will continue to grow in the future, and there are the following main trends.
Development of large and medium submersible electric pumps
The large and medium submersible electric pump has the outstanding advantages of simplifying the pump structure and saving the investment of the pump station construction. Generally, it can reduce the cost by 40% to 60% and shorten the time limit of 1/2 to 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. It is expected that the demand will be larger in the future.
Development of multi-function multi-purpose submersible pump
Submersible pump in the form of Chinese and foreign famous electric submersible pump production plant products than enough, such as the cutting device with the pump, multistage pump, pumping corrosive medium submersible pump production is little, but the market demand is very big, therefore, has a good development prospect.
Development of high reliability mechanical seal
Mechanical seal is the key part of submersible pump. It adopts two single end mechanical seals, so that the pressure of medium can act on the end surface. The leakage direction is internal flow pattern, which are all favorable, but the structure is slightly complicated. Two ends mechanical seal is installed in the oil chamber. The two sides should adopt different structural styles, so that the pressure of the medium can act on the lower side faces. Otherwise, only by spring force, the reverse thrust of the sealing face can easily open the ends. Therefore, it should be further studied in terms of structure and material to improve its reliability and life.
New materials, new technologies and new technologies will be gradually applied. Ordinary pumps have been made of stainless steel, fluoroplastics (F46), lining plastics, lining rubber and ceramic sprayed. All these materials should be applied to submersible pumps as soon as possible, and expand the application fields of submersible pumps. And the application of new technology and new technology, such as computer aided design, auxiliary manufacturing and auxiliary testing, is also imperative. It has been proved that the application of new technology, new material and new technology not only liberates the productivity of labor, but also ensures the stability and reliability of the product.
Pay attention to the appearance quality of submersible pump submersible pump and gradually enter the international market, our price has a significant competitive advantage in the international market, but must pay attention to improve pump reliability and life, especially to improve the appearance quality of the submersible pump, to give users a feeling of beauty, in order to make diving the domestic electric pump more into the international market as soon as possible.
