(1) Developing towards large-scale and high-speed development.
(2) To the direction of integration of machine, electricity and instrument with the continuous progress of technology, gear oil pump products will develop to the direction of intelligence, can monitor the pressure, flow, temperature and vibration parameters; Be able to evaluate the condition of pump shaft, bearing and seal; To diagnose the cause of the failure. In recent years, it has attracted attention mainly because of the increasing awareness of human environmental protection since the mid-1980s.
(3) Material technology
Modular pump technology is an important trend in the development of pump technology.
(4) To the direction of multi-variety and multi-use development
With the large-scale and large-scale development of power stations, petrochemical installations and water conservancy projects, pumps as supporting products are bound to develop in the direction of large-scale and high-speed development. .
(5) no sealing pump technology
The high technology of production and manufacturing is the fundamental guarantee of "low price and good quality". At the same time, the application of computer manufacturing integrated system (CIMS) and virtual technology has greatly shortened the production cycle of pump products and ensured the performance of the products.
Product whether it is a small household pump, gear pump used in construction such as general pump, or a large petrochemical, electric power industries in the process of pump device, to the direction of the machine, electricity, instrument integration development, make the pump products more efficient, energy saving, more convenient in operation and maintenance, improve reliability, prolong life, bring greater benefits for the user. The emphases of theoretical research are: measurement, numerical simulation and performance prediction of pump internal flow; Numerical calculation of unitary viscous flow; Theory and application of multiphase flow; Optimization and diversification of pump design. The technological development of the pump industry will focus on the design of electronic control systems, improving driving devices and seeking new materials.
(6) Scientific theory and design method
In order to meet the needs of different working conditions and uses, pump products are bound to expand varieties and specifications, expand the direction of performance range. Gear oil pump parts using a variety of new materials, the main benefits are to prolong the service life and reliability of the pump in corrosive media, and expand the scope of use of the pump.
(7) Product modularization and individualization
Non - sealed gear oil pump mainly includes magnetic drive pump and shield pump. At present, domestic pump products in terms of specifications, varieties and versatility still need to be further improved. At present, more and more pump manufacturers have realized the importance of adding a non-sealed pump in their product series. In recent years, the development and application of various new materials is an important factor to promote the development of pump technology. For example, for high pressure small flow pumps, mixed acid pumps and highly corrosive chemical slurry pumps, etc., still need to constantly develop new varieties. Through the use of advanced computer-aided design and computer-aided manufacturing technology, not only ensure the design quality of the product, but also shorten the design cycle, greatly improve the product design ability, realize the optimization of the design scheme, to ensure the reliability of the product. In the modular pump series, only a few parts can constitute the whole pump series, which can reduce the production cost, shorten the delivery time, reduce the inventory of parts and spare parts, and the development of personalized products is required to gradually tend to more varieties, small batch direction development. At the same time, coating technology and material surface treatment technology in improving pump flow characteristics, corrosion resistance and wear resistance has become increasingly important, with broad application prospects. It is obvious that the demand for non-sealed pumps will continue to grow strongly.
(8)CAD, CAM, CIMS technology development and promotion
Strengthen the basic theory of pump research, pay attention to cross disciplines, edge disciplines, emerging disciplines of mutual penetration.
