At present, domestic thermal oil pump products in terms of specifications, varieties and versatility still need to be further improved.
With the continuous progress of technology, 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. 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 recent years, it has attracted attention mainly because of the increasing awareness of human environmental protection since the mid-1980s. 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. 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. The key points of theoretical research are: measurement, numerical simulation and performance prediction of internal flow of high viscosity oil pump; Numerical calculation of unitary viscous flow; Theory and application of multiphase flow; Optimization and diversification of pump design. It is obvious that the demand for non-sealed pumps will continue to grow strongly. 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.
(1) Product modularization and individual-sui modularization pump technology is an important trend in the development of pump industry technology.
(2) scientific theory and design methods to strengthen the basic theory of pump research, pay attention to cross disciplines, edge disciplines, emerging disciplines of mutual penetration. 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.
(3) non sealed pump technology non sealed pump mainly includes magnetic drive pump and shield pump.
(4) to develop in the direction of machine, electricity, instrument integration of both small household pump, pump products used in construction such as general pump, or large petrochemical, electric power industries in the process of pump, are moving in the machine, electricity, instrument integration in the direction of development, make the pump more efficient, energy saving products, more convenient in operation and maintenance, improve reliability, prolong life, Bring more revenue to users.
(5) Developing towards large-scale and high-speed development.
(6) The development of CAD, CAM, CIMS technology and promotion of production and manufacturing of high technology is the fundamental guarantee of products "cheap and good quality". The components of the pump are made of a variety of new materials, and the benefits are mainly to prolong the service life and reliability of the pump in corrosive media, and expand the range of use of the pump. 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. At present, more and more pump manufacturers have realized the importance of adding a non-sealed pump in their product series.
(7) to a variety of varieties and multi-purpose direction to meet the needs of different working conditions and uses, pump products are bound to expand variety specifications, expand the direction of performance range. The technological development of the pump industry will focus on the design of electronic control systems, improving driving devices and seeking new materials. Article prepared by
