Fu yuwu, President of the China association of automobile engineers, said recently that electric drive will not replace internal combustion engine drive completely until 2050, during which time pumps and oil pumps will also face the challenges of lightweight and modular development.

To lead the trend of pump and pump industry in internal combustion engine industry, it is the basic skill to grasp the development trend of pump technology accurately. The development of pump technology, like the development of other industries, is driven by market demand. Nowadays, in the context of the huge demand generated by the high-tech development in the fields of environmental protection and electronics and the sustainable development of the world, rapid technological changes and development have been brought to many industries or fields, including the pump industry.

Energy conservation and emission reduction require technological innovation

With the continuous progress of technology, pump products will develop to the intelligent direction can monitor the pressure, flow, temperature and vibration parameters; able to evaluate the shaft, bearing and seal condition of the pump; able to diagnose the cause of fault. The technical development of magnetic pump and diaphragm pump industry will be mainly reflected in the design of electronic regulation system, improvement of driving device 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 pump and pay attention to the interdisciplinary, interdisciplinary and emerging disciplines. Theoretical research focuses on: measurement, numerical simulation and performance prediction of pump internal flow; Numerical calculation of unitary viscous flows; Theory and application of multiphase flow; Pump optimization design and design diversification.

The high technology of production and manufacturing is the fundamental guarantee of low price and high quality products. Through the use of advanced computer-aided design and computer-aided manufacturing technology, not only ensure the product design quality, but also shorten the design cycle, greatly improve the product design ability, achieve the optimization of the design scheme, ensure 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 the performance of the products.

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 whole pump series, which can reduce production costs, shorten delivery time, reduce parts and inventory, and personalized development requires that the product gradually tends to the direction of multiple varieties, small batch development.

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 are used in all sorts of new material, and the benefit of that is to extend the life and reliability of the pump in corrosive medium, and extend the range of the pump. At the same time, coating technology and material surface treatment technology in improving the flow characteristics and corrosion resistance of the pump has become increasingly important, with broad application prospects.

Traditional manufacturing is combined with information technology

Entering the information age today, pump designers have long used computer technology to carry out product development and design (such as the use of CAD), greatly improve the speed of the design itself, shorten the cycle of product design. And in the manufacturing of the main production, the manufacturing technology represented by the numerical control technology CAM has been deeply into the production of pumps. However, from the domestic situation, CNC technology CAM is mainly used in the production of bulk products. For the production of single or small batch, CAM technology has not been widely implemented in the pump industry at present, and the production of single or small batch is still dominated by traditional production equipment.

Due to market demand manufacturer of the goods time shorten as far as possible, especially for special products (products) for user's request supply cycle is shorten, inevitable requirement of pump production enterprises to accelerate the use of CAM technology, and even computer integrated manufacturing system (CIMS), a flexible manufacturing (FMC and FMS) from design to mold manufacturing, parts processing, such as coordinated process of each link, ensure that once the design is complete, product parts processing, tend to be completed during this period, in order to ensure to shorten the production cycle.

At the same time, in addition to the use of computer mapping will also be on the computer the carrier to achieve the strength of the product reliability analysis, forecast and three-dimensional design, the original need to find and solve process problems in production, local structure and assembly problems prior to production to protect against, shorten the trial production period of the product.

At the same time of product diversification, pump as a general product, the total volume is still huge. In the market, in addition to technical competition, the price competition of products, especially the price competition of generic products, is an inevitable trend. Under the trend of product diversification, it is necessary to realize the competitive advantage of product price, improve the standardization degree of product parts and realize the modularization of product parts. After the modularization of many parts, the product diversification 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 is improved can it be possible to conduct large-scale parts production on the basis of product diversification, so as to reduce the production cost of products and form the price competitive advantage of products, and further shorten the delivery cycle of products on the basis of product diversification.

The so-called internal characteristics of the pump refers to the inherent characteristics of the product, including product performance, parts quality, assembly quality of the whole machine, appearance quality, etc., or simply called quality. At this point, is the focus of many pump manufacturers, but also strive to improve, improve the aspect. However, in fact, we can find that many products are often unable to achieve the results of factory inspection after the factory inspection is sent to the user unit for operation, and such problems as overload, increased noise, use failure to meet the requirements, and reduced service life occur. And the pump in the actual running point or running characteristics, we call the external characteristics of the pump or system characteristics.

Technical personnel in product design, in order to improve the efficiency of a product 1% often spend a lot of thought; And if the pump operation deviates from the design of high efficiency point, the actual efficiency of operation is far more than one percent. Now, pump manufacturers for users at the same time supporting the control equipment including frequency conversion and complete sets of equipment, in fact, have been involved in the pursuit of external characteristics of the pump. On this basis, then pay attention to the centralized control system of the pump, improve the efficiency of the whole pump and pump station operation, is the pursuit of the external characteristics of the pump on a higher level.

From the point of view of sales, marketing products is to promote the inherent characteristics of the pump; The concern about the external characteristics of the pump is that the manufacturer is not only to promote the product, but also to promote the pump station (complete set of projects). From the perspective of use, a good product must be suitable for the operating environment of the product rather than the factory inspection and discrimination of the product.

Just like the development of science and technology, interdisciplinary and marginal disciplines in the field of science and technology are becoming more and more abundant. Interdisciplinary joint research is a very common thing, as well as the technical development of pump products. Take the shielded pump as an example, to eliminate the shaft seal problem of the pump, it must start from the motor structure, only limited to the pump itself is no way to achieve, to solve the noise problem of the pump, in addition to solving the flow state and vibration of the pump, but also need to solve the motor vane noise and electromagnetic field noise; To improve the reliability of submersible pump, measures such as leakage protection and overload protection must be added to the submersible motor to improve the efficiency of pump operation and the use of control technology and so on. These all do not indicate that to develop the pump technical level, it is necessary to start from supporting motor, control technology and other aspects at the same time, comprehensive consideration, to maximize the comprehensive level of mechanical and electrical integration.

Over the past decade, the use of new materials and new processes has been a major factor in the development of pump technology. Pump materials from cast iron to special metal alloys, from rubber products, ceramics and other typical non-metallic materials to engineering plastics, in the solution of the pump corrosion resistance, wear resistance, high temperature resistance and other environments have played a prominent role. At the same time, the use of new technology and better use of new materials to pump parts and even the whole pump. For example, some foreign manufacturers have designed and launched all the use of engineering plastic made of the pump. Compared with the general metal production of the pump in strength is not inferior, in corrosion resistance and wear resistance on the better. For example, the use of new surface coating technology and surface treatment technology, the same pump can solve the problem of corrosion and wear resistance. With the further development of new materials and the in-depth application of new technology, the application in the field of pump will be more extensive.
