Pump technology development as other industries, is driven by market demand. Now, the history has entered the twenty-first Century, people in the background of huge demand to the high-tech development of environmental protection, electronics and other fields and the sustainable development of the world mainly produced by the pump industry, including, for many industries or fields have brought the rapid change and development of technology.
In recent years, the development trend of pump technology mainly has the following points:
1 、Product diversification
Product vitality lies in the market demand. Today's market demand is required to have their own characteristics, so different; it is this, creating a diversified trend of pump products. Its diversity is mainly reflected in the diversity of the pump delivery medium, the difference of the product structure and the different requirements of the operation.
From the diversity of transport medium, conveying the first object into a single water pump and other flowable liquid, gas or slurry can be transported up to now, the solid-liquid mixture gas-liquid mixture, solid liquid gas mixture, and transporting live objects such as potatoes, fish and so on. Different conveying objects have different requirements for the internal structure of the pump.
In addition to the different requirements of the pump on the structure of the pump, the pump installation, pipeline layout, maintenance and other aspects of the pump's internal or external structure of the new requirements. At the same time, the various manufacturers, in the structure of the design and joined the concept of their own companies, and further improve the diversification of the pump structure.
The general background of sustainable development and environmental protection based on the operating environment of the pump design of the pump and put forward many requirements, different focus or focus of several parallel should consider such as leakage, reducing noise and vibration reduction, increase the reliability and life of pump design and so on are put forward, will form a diversified form of pump.
2、product standardization and modularization
Diversified products at the same time, the pump as a general product, the overall amount 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 of product parts, and realize the modularization of product parts. In many parts of the modular, through the combination of different modules or change the characteristics of individual parts, in order to achieve product diversification. At the same time, only when the parts standardization extent can be based on the actual size of product diversification of parts production based on, to reduce the cost of production and the formation of the price of the product competitive advantage, can further shorten the product on the basis of product diversification of the delivery cycle.
3、 pump intrinsic characteristics of ascension and the pursuit of external characteristics
The inherent characteristics of the pump is the inherent characteristics of the product, including product performance, parts quality, assembly quality, appearance quality, etc., or referred to as quality. At this point, is the focus of many pump production companies are also efforts to improve, improve aspects. In fact, we can find that there are many products to meet the use of units running in factory testing, often reach the factory test results, such as overload, noise increases, the use is not up to the requirements or reduce the life and other aspects of the problem; and the pump in practical operation or operation the characteristics, we call the pump external characteristics or system characteristics.
Technical personnel in product design, in order to improve the efficiency of a product one percent often takes a lot of thought; and if the pump running off design efficiency, actual running efficiency is more than one percent lower. Now, the pump production company at the same time supporting the user, including variable frequency control equipment and complete sets of equipment, in fact, has been involved in the pursuit of the external characteristics of the pump. On this basis, and then focus on the centralized control system, improve the efficiency of the pump and pump station, it is in the pursuit of the pump characteristics of a higher level.
4 、further development of mechanical and electrical integration
The same as the development of science and technology, science and technology in the current stage in the field of cross subjects and more and more common, interdisciplinary research is a very common thing, as the technology development of pump products is also true. With the shield type pump as an example, cancel the seal problem of pump, we must start from the structure of the motor, confined to the pump itself, there is no way to achieve; to solve the noise problem of the pump, in addition to flow and vibration settlement pump, noise at the same time to solve noise and electromagnetic field of the fan blade; improve the reliability of the submersible pump. Must be in the submersible motor is arranged such as leakage protection, overload protection measures; improve the efficiency of the pump, should use with control technology etc.. All these indicate that the development of pump technology level, we must start from the supporting motor, control technology and other aspects at the same time, taking into account, to maximize the integration of mechanical and electrical integration.
5 、accelerated use of new materials and new processes
Over the past more than and 10 years, the use of new materials and new technology is to promote the development of pump technology is a major factor. Pump with materials from cast iron to special metal alloy, rubber, ceramics etc. from typical non-metallic materials to solve in engineering plastics, corrosion resistance, pump abrasion resistance and so on, the environment have played a prominent role. At the same time, the application of new technology.
