Gear pump industry technology development new direction
In 2020, with the continuous progress of technology, gear pump products will definitely develop towards intelligent direction, which can monitor the parameters such as pressure, flow, temperature and vibration.Be able to evaluate the condition of pump shaft, bearing and seal;Be able to diagnose the cause of the fault.The technical development of the pump industry will focus on the design of electronic regulating systems, the improvement of driving devices and the search for new materials.
(1) Develop towards the integration of machine, electricity and instrument
Whether it is a small household pump, gear pump products used in construction such as general pump, or a large petrochemical, electric power industries in the process of pump device, are moving in the machine, electricity, instrument integration in the direction of 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.
(2) To the large-scale and high-speed direction of development
With the development of power station, petrochemical plant and water conservancy project towards large scale and scale, pump as its supporting products will inevitably develop towards large scale and high-speed direction.
(3) To the multi-varieties and multi-purpose direction of development
In order to meet the needs of different working conditions and applications, pump products are bound to expand the specifications, expand the scope of performance development direction.At present, domestic pump products in the specification, variety and wide use of the aspects still need to be further improved.For example, for high pressure low flow pump, mixed acid pump and highly corrosive chemical slurry pump, but also need to develop new varieties.
(4) Scientific theory and design method
Strengthen the basic theory research of pump, pay attention to the interpenetration of cross discipline, edge discipline and emerging discipline.The emphases of theoretical research are: measurement, numerical simulation and performance prediction of pump internal flow;Numerical calculation of one dimensional viscous flow;Theory and application of multiphase flow;Pump optimization design and design diversification.
(5) Development and promotion of CAD, CAM and CIMS technology
The high technology of production and manufacturing is the fundamental guarantee of the product "low price and high quality".Through the use of advanced computer-aided design and computer-aided manufacturing technology, not only to ensure the design quality of the product, but also shorten the design cycle, greatly improve the product design ability, to achieve the optimization of the design scheme, ensure the reliability of the product.At the same time, the application of computer manufacturing integrated system and virtual technology greatly shorten the production cycle of pump products and ensure the performance of products.
(6) No seal pump technology
Non-sealing pump mainly includes magnetic drive pump and shielded pump.In recent years, it has attracted much attention mainly because of the increasing awareness of environmental protection since the mid-1980s.At present, more and more pump manufacturers realize the importance of adding an unsealed pump to their product line.It is clear that the demand for unsealed pumps will continue to grow strongly.
(7) Product modularization and individualization
Modular pump technology is an important trend in the development of pump industry technology.In the modular pump series, only a few parts are needed to constitute the whole pump series, which can reduce the production cost, shorten the delivery time, reduce the inventory of spare parts and spare parts, while the personalized development requires that the products gradually tend to develop towards the direction of multiple varieties, small batch.
(8) Material technology
In recent years, the development and application of various new materials is an important factor to promote the development of pump technology.Gear pump parts using a variety of new materials, the benefits of the main is to extend the service life and reliability of the pump in corrosive medium, and expand the use of the pump range.At the same time, coating technology and material surface treatment technology in improving the flow characteristics, corrosion resistance and wear resistance of the pump has become increasingly important, with broad application prospects.
