However, we must pay attention to improve the reliability and life of the pump, pay attention to the quality of the submersible pump and gradually enter the international market, China's submersible pump in the international market has obvious price competitive advantage. In particular, to improve the appearance of submersible pump quality, to give users a kind of beauty, so that the domestic submersible pump more and more into the international market.
Therefore, there are many advantages due to the submersible pump itself and the submersible pumping station. In the future, the demand of our country will continue to grow with the following major development trends.
Generally reduce costs 40% 60% Shorten the construction period of 1/22/3
1. The development of large and medium-sized submersible pump Large and medium-sized submersible pump pump structure has been simplified and save pumping station construction investment outstanding advantages. Will be more widely used in municipal, mining, environmental protection and industrial and agricultural drainage and so on. Expected future demand will be greater. Submersible pumps, such as pumps with cutting devices, multistage pumps, and pumping corrosive media, are still rare.
2. The development of multi-purpose multi-purpose submersible pump Submersible pump in China in the form of well-known foreign manufacturers and submersible pump compared to not enough. However, its market demand is very large, therefore, has a good development prospects. Two single-ended mechanical seals are used.
3. Development of high reliability mechanical seal Mechanical seal is a key part of the submersible pump. This medium pressure can be applied to the end face, the direction of leakage for the inflow, which are beneficial but the structure is slightly complicated. Oil chamber with double-sided mechanical seal, the two sides of the end face should be of different types of structure, so that the media pressure can be applied to the lower side of the end surface, otherwise only by spring force, sealing the end of the thrust easy to open the end face. Therefore, further research should be conducted on the structure and information to improve its reliability and life expectancy. All of this information should be applied to the submersible pump as soon as possible.
4. New materials and new technologies and new technology will be gradually applied ordinary pumps have been used stainless steel, fluorine plastic (F46 lined plastic, rubber lining, spraying ceramics, etc. to expand the submersible pump applications. And computer-aided design, manufacturing and testing aids The application of new technologies and new processes is also imperative.It turns out that the application of new technologies, new materials and new processes not only liberate labor productivity and sanitation pumps, but also ensure the product quality is stable and reliable.
- Dandy lift make any job easier. Dandy Lift portable scissor lift carts are essential anywherethat lifting, positioning, assembling, stacking, unstacking, transporting or the need for anadjustable height work surface is part of the job.
- Dandy Lift carts feature ergonomically shaped handles with comfort grip padding. The scissorlift mechanism is actuated by a simple manual foot pump
- Dandy lift greatly reduce the labor intensity of workers and improve work efficiency.
