Development Status and Overall Trend of World Pump Technology
Pump technology development, as the development of other industries, is driven by market demand. Today, history has entered the twenty-first century, people in the environmental protection, electronics and other areas of high-tech development and the world's sustainable development based on the huge demand for the background, including the pump industry, including many industries or areas Have brought rapid technological change and development.In recent years, pump technology development trends are the following:1. product diversificationProduct vitality lies in the needs of the market. Today's market demand is to require their own characteristics, to be different; it is this, creating a diversified trend of pump products. Its diversity is mainly reflected in the diversity of pump delivery media, product structure differences and different requirements of the operation of several aspects.From the viewpoint of the diversity of the conveying medium, the earliest pump is delivered as a single water and other flowable liquid, gas or slurry to the present transport of solid-liquid mixtures, gas-liquid mixtures, solid-liquid mixtures until transport Objects such as potatoes, fish and so on. Different delivery objects are different for the internal structure of the pump.In addition to the transport of objects on the structure of the pump have different requirements, the pump in the form of installation, pipe layout, maintenance and repair aspects of the pump on the internal or external structure of the new requirements. At the same time, the various manufacturers, in the design of the structure has joined the concept of their own businesses, and more to improve the degree of diversification of the pump structure.Based on the overall background of sustainable development and environmental protection, the operating environment of the pump has put forward many requirements for the design of the pump, such as reduced leakage, reduced noise vibration, increased reliability, extended life and so on. Focus or a few focus on parallel must be considered, but also the formation of a variety of forms of the pump.2. Pump design level and manufacturing technology to optimize the organic combinationInto the information age today, pump designers have long been using computer technology to product development and design (such as the use of CAD), greatly improving the design of their own speed, shorten the product design cycle. In the production-based manufacturing, CNC technology CAM as the representative of the manufacturing technology has been deep into the pump production. However, from the current domestic situation, CNC technology CAM is mainly used in the production of bulk products. For single or small batch production, the current CAM technology has not yet generally implemented in the pump industry, single-piece production is still small batch of traditional production equipment.As the market requires manufacturers to shorten the delivery period as much as possible, especially for special products (for the user requirements of the product) supply cycle shortened, the pump manufacturers must be required to accelerate the use of CAM technology, and even computer integrated manufacturing system (CIMS) Flexible manufacturing (FMC and FMS) from design to manufacturing molds, parts processing and other aspects of coordination to ensure that once the design is completed, the product parts processing is also completed over the same period to ensure shorten the production cycle.At the same time, in addition to the use of computer graphics, but also in the computer on the carrier to achieve product strength analysis, reliability prediction and three-dimensional design, the original need to find and solve the production process and local structural problems and assembly Sexual problems and other aspects of the production before the prevention, shorten the trial period of the product.3. Product standardization and modularizationIn the product diversification at the same time, the pump as a general product, the overall total is still huge. In the market, in addition to technical competition, the product price competition, especially the price of generic products is an inevitable trend of competition. In the trend of diversification of products, to achieve the competitive advantage of product prices, improve the standardization of product parts and components, to achieve the modular product parts is necessary. After the modularization of many components, through the combination of different modules or change the characteristics of individual parts to achieve product diversification. At the same time, only when the degree of standardization of parts and components can be based on the diversification of products based on the actual scale of the actual production of components to reduce the production cost of products and the formation of product price competitive advantage, but also in the product diversification On the basis of further shortening the product delivery cycle.4. Pump internal characteristics of the promotion and the pursuit of external characteristicsThe inherent characteristics of the pump refers to the inherent characteristics of the product, including product performance, component quality, machine assembly quality, appearance quality, etc., or simply referred to as quality. At this point, many pump manufacturers are concerned about the efforts to improve, improve the aspects. In fact, we can find that there are many products in the factory to meet the detection of the use of units to run, often less than the factory factory inspection results, such as overload, increased noise, the use of less than the requirements or reduced life And other aspects of the problem; and the pump in the actual operation of the operating point or operating characteristics, we call the pump's external characteristics or system characteristics.Technical staff in the product design, in order to improve the efficiency of a product often spend a lot of effort; and pump operation if deviated from the design of the efficient point, the actual operation of the efficiency far more than one percent reduction. Now, the pump manufacturers at the same time supporting the user, including inverter, including control equipment and complete sets of equipment, in fact, has been involved in the pursuit of the external characteristics of the pump on the. On this basis, and then focus on the pump centralized control system to improve the efficiency of the pump and pump operation, it is in the pursuit of the characteristics of the pump on a higher level.From the sales point of view, selling products that is selling the pump's inherent characteristics; and pay attention to the external characteristics of the pump is not only the manufacturer to sell products, but in the sales pump (complete sets of projects).From the use point of view, a good product must be suitable for the environment of the product rather than factory inspection and identification of products.5. Further development of mechanical and electrical integrationAs with the development of science and technology, at the present stage of science and technology in the field of interdisciplinary, increasingly rich edge, interdisciplinary joint research is very common thing, as the pump product technology development is also true. In order to solve the problem of pump noise, in addition to solve the pump flow and vibration, but also need to solve the problem, the pump can not be solved by the pump structure, The noise of the motor blades and the noise of the electromagnetic field; to improve the reliability of the submersible pump, must be added in the submersible motor such as leakage protection, overload protection and other measures to improve the efficiency of the pump, with the help of the use of control technology and so on. These are all to explain the level of development of pump technology, must be from the matching motor, control technology and other aspects at the same time, comprehensive consideration, to maximize the integration of mechanical and electrical integration level.6. The rapid use of new materials and new technologyOver the past decade or so, the use of new materials and new processes is 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 and other environments have played a prominent role. At the same time the use of new technology, and better use of new materials to the pump parts still into the pump. Some foreign manufacturers have been designed and introduced all the use of engineering plastics made of pumps. Than with the general production of metal materials in the strength of the pump no less, in the corrosion resistance on the better. Another example is the use of new surface coating technology and surface treatment technology, the same can solve the pump corrosion and anti-wear problems. The further development of new materials and the use of new technology in the field of the application of the pump will be more extensive.
