Along with the science and technology products will continue to improve, intelligent type valve, can monitor the pressure, flow rate, temperature and vibration; to evaluate the pump shaft, bearing and seal condition; to diagnose the reasons for failure. The technical development of the pump industry will focus on the design of electronic control system, improve the driving device and seek new materials and so on
1) towards the direction of large scale and high speed.
With the development of petrochemical, power station and water conservancy project in the direction of large scale and large scale, the pump as its supporting products is bound to develop in the direction of large scale and high speed
2) to electric, machine, instrument integration direction
Whether the pump pump pump pump, general household building small, flow pump or petrochemical, electric power and other industrial equipment with large, continuous development in the integration to electricity, machine, instrument direction, pump products must be more efficient, energy saving, maintenance more convenient, improve the reliability and prolong the life of.
3) the scientific theory and design method
To strengthen the basic theory of the pump, focusing on cross disciplinary, interdisciplinary, emerging disciplines of mutual penetration. The theoretical research focuses on the measurement of the flow inside the pump, the numerical simulation and performance prediction, the numerical calculation of one dimensional viscous flow, the theory and application of multiphase flow, the optimal design of pump and the diversification of design.
4) toward the development of multi variety and multi purpose
In order to meet the requirements of different working conditions and uses, the pump products are bound to expand the variety of specifications, expand the scope of performance. At present, the domestic pump products in terms of specifications, varieties and uses of the extensive need to be further improved. For high pressure small flow pump, mixed acid pump and corrosive chemical slurry pump, but also need to continue to develop new varieties.
5) CAD, CAM, CIMS technology development and promotion
High technology production and manufacturing of products "is the fundamental guarantee cheap". Through the use of advanced computer aided design and computer aided manufacturing technology, not only to ensure the quality of product design, and shorten the design cycle, greatly improving the ability of product design, to achieve the optimal design scheme, to ensure the reliability of the product. At the same time, the application of computer integrated manufacturing system (CIMS) and virtual technology, greatly shorten the production cycle of pump products, to ensure the performance of the product.
6) product modularization and - Gui Hua
Modular pump technology is an important trend in the development of pump technology. In the modular pump series, only a few parts can constitute the entire pump series, which can reduce production cost, shorten delivery time, reduce spare parts and spare parts inventory, and personalized development requires products tend towards multi variety and small batch direction.
7) material technology
In recent years, the development and application of various new materials is an important factor to promote the development of pump technology. The parts of the pump adopt a variety of new materials, the benefits are mainly to extend the service life and reliability of the pump in corrosive medium, and expand the scope of the use of the pump. At the same time, the surface treatment technology of coating technology and materials becomes more and more important in improving the flow characteristics, corrosion resistance and wear resistance of the pump.
8) no seal pump technology
Non sealed pump mainly includes magnetic drive pump and shield pump. In recent years, the main reason is mainly due to the increasing awareness of environmental protection since the mid 1980s. At present, more and more pump manufacturers recognize the importance of the need to add a non sealed pump in its product range. Obviously, no strong demand will be sustained growth of the pump seal.
