We have summarized the development trend of technological innovation in the pump industry in recent years mainly as follows:
1. The organic combination of pump design level improvement and manufacturing technology optimization
In today’s information age, pump designers have already used computer technology to develop and design products (such as the use of CAD), which greatly improves the speed of design itself and shortens the cycle of product design. At the same time, in addition to using computer graphics, the strength analysis, reliability estimation and three-dimensional design of the product will also be realized on the carrier of the computer, and the process problems, local structural problems and assembly problems that need to be discovered and solved in production will be solved. Sexual issues and other aspects are mentioned before production to prevent and shorten the trial production period of products.
2. Improving the internal characteristics of the pump and pursuing the external characteristics
At the same time, pump manufacturers 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, focusing on the centralized control system of the pump and improving the operating efficiency of the entire pump and pumping station will lead to a higher level of pursuit of the pump’s external characteristics.
3. Diversification of products
From the perspective of the diversity of conveying media, the earliest pumps were used to convey a single water and other flowable liquids, gases or slurries, and now they can convey solid-liquid mixtures, gas-liquid mixtures, solid-liquid-gas mixtures, and even live animals. Objects such as potatoes, fish, etc. Different conveying objects have different requirements for the internal structure of the pump. In addition to the different requirements of the pump structure for the conveying objects, new requirements are put forward for the internal or external structure of the pump in terms of pump installation form, pipeline layout form, maintenance and repair, etc. At the same time, each manufacturer has added their own ideas in the structural design, which has further improved the diversification of the pump structure.
4 Standardization and modularization of products
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. After many components are modularized, product diversification can be realized by combining different modules or changing the characteristics of individual parts.
5. Further development of mechatronics
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 use of control technology and so on. These all show that in order to develop the level of pump technology, we must start from the supporting motor and control technology at the same time, comprehensively consider, and maximize the comprehensive level of mechatronics.
6. Accelerated utilization of new materials and new processes
Pump materials range from cast iron to special metal alloys, from rubber products, ceramics and other typical non-metallic materials to engineering plastics, which play a prominent role in solving the corrosion resistance, wear resistance and high temperature resistance of pumps. At the same time, the application of new technology makes it better to apply new materials to the parts of the pump and to the whole pump.
