New trend of domestic pump technology (2)

Pump internal characteristics of the promotion and the pursuit of the external characteristics of the so-called pump intrinsic characteristics of the product performance is included, the quality of parts, machine assembly quality, appearance quality, etc. inherent characteristics of the product, or simply referred to as the quality. At this point, many pump manufacturers are also concerned about the current efforts to improve and improve. In fact, we can find that there are many products that fail to meet the factory inspection after they are sent to the use unit for testing. If there are many problems such as overload, noise increase, unacceptable use or loss of life expectancy And other aspects of the problem; and the pump in which the actual operating point or operating characteristics, which we call the pump's external characteristics or system characteristics. Technicians often spend a lot of time trying to improve the efficiency of a certain product during product design. If the pump operation deviates from the high efficiency point of the design, the actual operation efficiency is far more than reduced by 1%. Now, pump manufacturers at the same time supporting the user, including the frequency of the 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, focus on the pump centralized control system to improve the efficiency of the entire pump and pumping station, it is in the pursuit of the external characteristics of the pump to a higher level. From a sales point of view, selling a product is the intrinsic characteristic of a sales pump. Concerning the external characteristics of a pump, manufacturers are not only selling products, but also pumping stations (complete sets of projects). From the use point of view, a good product must be suitable for the operating environment of the product rather than the factory test to determine the product. The further development of mechanical and electrical integration just like the development of science and technology. At this stage of interdisciplinary science and technology, more and more edge discipline, interdisciplinary joint research is very common thing, as the pump technology development as well. Shielded pump, for example, to remove the pump shaft seal, the structure must start from the motor, only the pump itself is no way to achieve, to solve the pump noise problems, in addition to solve the pump flow and vibration, at the same time need to be resolved Motor fan noise and electromagnetic noise; improve submersible pump reliability, you must add in the submersible motor such as leakage protection, overload protection and other measures; to improve the pump operating efficiency, the need to help control the use of technology and so on. These all show that to develop the level of pump technology, we must start from the supporting motor, control technology at the same time, comprehensive consideration, to maximize the overall level of mechanical and electrical integration. Accelerate the use of new materials and new processes The past decade or so, the use of new materials and new technology is to promote the development of pump technology is a major factor. Pump materials from cast iron to special metal alloys, from rubber products, ceramics and other typical non-metallic materials to engineering plastics, pump to solve the corrosion resistance, wear resistance, high temperature and other environments have played a prominent role. At the same time the use of new technology, but also make better use of new materials to the pump parts and even the pump. Some foreign manufacturers, for example, have designed and launched a pump made entirely of engineering plastics. Than the general use of metal materials in the pump on the strength of no less favorable than in the anti-corrosion wear superior. As another example, the use of new surface coating technology and surface treatment technology, the same pump can solve the problem of corrosion and abrasion. The further development of new materials and the application of new technology in-depth, the pump will be more widely used in the field.
