Information
Fu Yuwu, chairman of the Chinese Society of Automotive Engineers, said not long ago that with the need for energy conservation and emission reduction and intelligent development, the automotive industry is destined to undergo disruptive changes. Lightweight and modularization is the future development trend of the automotive industry. Advanced lightweight materials such as aluminum, composite materials, and carbon fiber materials will be widely used in the automotive field. "Before 2050, electric drives will still not be able to completely replace internal combustion engine drives. During this period, water pumps and oil pumps will also face the challenges of lightweight and modular development."
To lead the trend of the water pump and oil pump industry in the internal combustion engine industry, it is the basic skill to accurately grasp the development trend of pump technology. The development of pump technology, like the development of other industries, is driven by market demand. Nowadays, under the background of the huge demand generated by the high-tech development of environmental protection, electronics and other fields and the world's sustainable development, many industries or fields including the pump industry have brought rapid technological changes and developments. .
Energy saving and emission reduction require technological innovation
With the continuous advancement of technology, pump products will inevitably develop in the direction of intelligence, capable of monitoring parameters such as pressure, flow, temperature and vibration; able to evaluate the condition of the pump shaft, bearing and seal; able to determine the cause of the failure Make a diagnosis, etc. The technological development of the magnetic pump and diaphragm pump industry will be concentrated in the design of electronic adjustment systems, improvement of drive devices, and the search for new materials.
It is necessary to make the theory and design method scientific. Therefore, it is necessary to strengthen the basic theoretical research of pumps and pay attention to the mutual penetration of interdisciplinary, fringe and emerging disciplines. The focus of theoretical research is: measurement, numerical simulation and performance prediction of pump internal flow; numerical calculation of univariate viscous flow; theory and application of multiphase flow; optimal design and diversification of pump design.
High-tech production and manufacturing are the fundamental guarantee for low-cost and high-quality products. By using advanced computer-aided design and computer-aided manufacturing technology, it not only guarantees the design quality of the product, but also shortens the design cycle, greatly improves the product design ability, realizes the optimization of the design scheme, and ensures the reliability of the product. 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 product performance.
Modular pump technology is an important trend in the technological development of the pump industry. In the modular pump series, only a few parts are needed to form the entire pump series, which can reduce production costs, shorten delivery time, reduce parts and stocks, and the development of individualization requires products to gradually trend Yu is developing in the direction of multiple varieties and small batches.
In recent years, the development and application of various new materials is an important factor in promoting the development of pump technology. The parts of the pump adopt a variety of new materials, and the main benefits are to extend the service life and reliability of the pump in corrosive media, and expand the scope of use of the pump. At the same time, coating technology and material surface treatment technology have become increasingly important in improving the flow characteristics and corrosion resistance of pumps, and have broad application prospects.
Combination of traditional manufacturing and information technology
Today in the information age, pump designers have already used computer technology for product development and design (such as the use of CAD), greatly improving the speed of the design itself and shortening the product design cycle. In the production-oriented manufacturing, the manufacturing technology represented by the numerical control technology CAM has penetrated into the production of pumps. However, judging from the domestic situation a few days ago, the numerical control technology CAM is mainly used in the production of mass products. For single-piece or small-batch production, CAM technology has not yet been widely implemented in the pump industry, and single-piece and small-batch production is still dominated by traditional production equipment.
As the market requires manufacturers to shorten the delivery period as much as possible, especially for special products (products produced according to user requirements), the supply cycle will inevitably require pump manufacturers to accelerate the use of CAM technology and even computer integrated manufacturing systems (CIMS) and flexibility. Manufacturing (FMC and FMS) coordinately handle all links from design to manufacturing molds, parts processing, etc., to ensure that once the design is completed, the processing of product parts tends to be completed at the same time to ensure that the product production cycle is shortened.
At the same time, in addition to the use of computer graphics, product strength analysis, reliability prediction and three-dimensional design will be realized on the computer carrier, which will eliminate the process problems, local structural problems and assembly problems that originally needed to be discovered and resolved in production. Issues and other aspects are raised to take precautions before production to shorten the trial production period of the product.
While the products are diversified, as a general-purpose product, the total amount of pumps is still huge. In the market, besides the emergence of technical competition, the price competition of products, especially the price competition of generalized products, is an inevitable trend. Under the trend of product diversification, it is necessary to realize the competitive advantage of product prices, improve the standardization of product parts, and realize the modularization of product parts. After many parts have been modularized, the diversification of products can be realized by combining different modules or changing the characteristics of individual parts. At the same time, only when the degree of standardization of parts and components is improved, it is possible to produce parts on a real scale based on the diversification of products, which can be used to reduce the production cost of products and form a price competitive advantage of products. On the basis of further shortening the product delivery cycle.
The so-called inherent characteristics of the pump refer to the inherent characteristics of the product including product performance, quality of parts, assembly quality, appearance quality, etc., or simply called quality. At this point, it is currently the focus of many pump manufacturers, and it is also an aspect that strives to improve and improve. In fact, we can find that many products are tested in the factory and sent to the user unit for operation, but they often fail to achieve the results of the factory inspection, such as overload, increased noise, unsatisfactory use, and reduced life expectancy. Aspects of the problem; and the operating point or operating characteristics of the pump in practice, we call it the external characteristics or system characteristics of the pump.
When designing a product, technicians often spend a lot of effort to improve the efficiency of a product by one percent; and if the pump operation deviates from the high efficiency point of the design, the actual operation efficiency is far more than one percent reduction. Now, pump manufacturers also provide users with control equipment and complete sets of equipment including frequency conversion, which has actually been involved in the pursuit of the external characteristics of the pump. On this basis, paying attention to the centralized control system of the pump and improving the operation efficiency of the entire pump and pumping station is a higher level in the pursuit of the external characteristics of the pump.
From a sales perspective, promoting products is to promote the internal characteristics of pumps; while focusing on the external characteristics of pumps, manufacturers are not only promoting products, but also promoting pumping stations (packaged projects). From the perspective of use, a good product must be a product suitable for the operating environment rather than a product determined by factory inspection.
Just like the development of science and technology, at this stage, the interdisciplinary and marginal disciplines in the field of science and technology are becoming more and more abundant, and interdisciplinary joint research is very common, as is the technological development of pump products. Taking the canned motor pump as an example, the cancellation of the shaft seal problem of the pump must start from the motor structure. It is impossible to solve the problem of pump noise. In addition to solving the flow pattern and vibration of the pump, it needs to be solved at the same time. The noise of the fan blades of the motor and the noise of the electromagnetic field; to improve the reliability of the submersible pump, measures such as leakage protection and overload protection must be added to the submersible motor; to improve the operating efficiency of the pump, it is necessary to rely on the application of control technology and so on. All these indicate that in order to develop the pump technology level, it is necessary to start at the same time from the supporting motors, control technology and other aspects, comprehensively consider, and maximize the comprehensive level of mechatronics.
In the past ten years or so, the application of new materials and new processes has been a major factor driving the development of pump technology. Pump materials ranging from cast iron to special metal alloys, from typical non-metallic materials such as rubber products and ceramics to engineering plastics, play a prominent role in solving the corrosion resistance, wear resistance, and high temperature resistance of the pump. At the same time, the application of new technology makes it better to apply new materials to pump parts and even the entire pump. For example, some foreign manufacturers have designed and launched pumps all made of engineering plastics. It is not inferior in strength to pumps made of general metal materials, and is better in corrosion resistance and wear resistance. Another example is the use of new surface coating technology and surface treatment technology, which can also solve the anti-corrosion and anti-wear problems of the pump. With the further development of new materials and the in-depth application of new processes, the application in the field of pumps will be more extensive.
