The Technological Development Trend Of Pumps
The technological development of pumps, like the development of other industries, is driven by market demand. Nowadays, history has entered the 21st century. Against the backdrop of the enormous demand for high-tech development in fields such as environmental protection and electronics, as well as global sustainable development, many industries or fields, including the pump industry, have undergone rapid technological changes and developments.
In recent years, the technological development trends of pumps mainly include the following points:
1. Diversification of products
The vitality of a product lies in the demand of the market. The current market demand requires each individual to have their own unique characteristics and achieve uniqueness; It is precisely this that has created a diversified trend in pump products. Its diversity is mainly reflected in several aspects such as the diversity of the medium conveyed by the pump, the differences in product structure, and the differences in operating requirements.
From the diversity of conveying media, the conveying objects of early pumps are single water and other flowing liquids, gases, or slurries. Nowadays, they can transport solid-liquid mixtures, gas-liquid mixtures, solid-liquid gas mixtures, and even live objects such as potatoes and fish. Different conveying objects have different requirements for the internal structure of the pump.
In addition to the different requirements of the conveying object for the pump structure, new requirements are proposed for the internal or external structure of the pump in terms of installation form, pipeline layout, maintenance and repair, etc. At the same time, various manufacturers have incorporated their own corporate concepts into the structural design, further enhancing the diversity of pump structures.
Based on the overall background of sustainable development and environmental protection, the operating environment of pumps has put forward many requirements for pump design, such as reducing leakage, reducing noise and vibration, increasing reliability, extending service life, etc., all of which have put forward different focuses or several key points that need to be considered in parallel, inevitably forming diversified forms of pumps.
2. The organic combination of improving pump design level and optimizing manufacturing technology
In today's information age, pump designers have already utilized computer technology for product development and design (such as the use of CAD), greatly improving the speed of design itself and shortening the product design cycle. In production oriented manufacturing, manufacturing technologies represented by CNC technology CAM have penetrated into pump production. However, from the current situation in China, CNC technology CAM is mainly applied in the production of batch products. For single piece or small batch production, CAM technology has not yet been widely implemented in the pump industry, and traditional production equipment is still the main method for single piece and small batch production.
Due to the market demand for manufacturers to shorten their lead times as much as possible, especially for special products (products produced according to user requirements), the supply cycle must be shortened. This inevitably requires pump manufacturers to accelerate the use of CAM technology, and even computer integrated manufacturing systems (CIMS), flexible manufacturing (FMC and FMS) to coordinate and handle all aspects from design to manufacturing molds, part processing, etc. Once the design is completed, The processing of product components also tends to be completed simultaneously to shorten the production cycle of the product.
At the same time, in addition to using computer graphics, the strength analysis, reliability estimation, and three-dimensional design of products will also be achieved on the computer as a carrier. The process problems, local structural problems, and assembly problems that originally needed to be discovered and solved in production will be brought up for prevention before production, shortening the trial production period of the product.
3. Standardization and modularization of products
While product diversification has emerged, pumps, as a universal product, still have a huge overall quantity. In the market, besides technical competition, price competition of products, especially price competition of generic products, is an inevitable trend. In the trend of product diversification, it is necessary to achieve a competitive advantage in product prices, improve the standardization of product components, and achieve modularization of product components. After modularization of numerous components, product diversification can be achieved by combining different modules or changing the characteristics of individual parts. At the same time, only when the standardization level of components is improved can it be possible to actually scale the production of components based on product diversification, in order to reduce production costs and form a competitive advantage in product prices. It can also further shorten the delivery cycle of products on the basis of product diversification.
4. Improvement of pump internal characteristics and pursuit of external characteristics
The inherent characteristics of a pump refer to the inherent characteristics of the product, including product performance, component quality, overall assembly quality, appearance quality, etc., or simply referred to as quality. At this point, many pump manufacturers are currently focusing on and striving to improve. In fact, we can find that many products that meet the factory inspection requirements and are sent to the user unit for operation often fail to achieve the factory inspection results, resulting in problems such as overload, increased noise, failure to meet usage requirements, or reduced lifespan; The operating point or characteristic of the pump in practice is called the external characteristic or system characteristic of the pump.
Technicians often put a lot of effort into improving the efficiency of a certain product by one percent during product design; If the pump deviates from the design point during operation, the actual efficiency of operation will be reduced by more than one percent. Now, pump manufacturers are simultaneously providing users with control equipment and complete sets of equipment, including frequency conversion, which has actually become involved in the pursuit of the external characteristics of pumps. On this basis, further attention should be paid to the centralized control system of the pump to improve the operational efficiency of the entire pump and pumping station, which is to further pursue the external characteristics of the pump.
From a sales perspective, promoting a product is promoting the inherent characteristics of a pump; However, focusing on the external characteristics of pumps means that manufacturers are not only promoting products, but also promoting pump stations (complete projects).
From a usage perspective, a good product must be a product that is suitable for the operating environment rather than a product that is judged by factory testing.
5. Further development of mechatronics integration
Just like the development of science and technology, interdisciplinary and interdisciplinary research is becoming increasingly abundant in the field of technology at present. Cross disciplinary joint research is very common, and the same is true for the technological development of pump products. Taking a shielded pump as an example, canceling the shaft seal problem of the pump must start from the motor structure, and it is impossible to achieve it solely by limiting it to the pump itself; To solve the noise problem of pumps, in addition to addressing the flow and vibration of the pump, it is also necessary to address the noise of the motor blades and electromagnetic fields; To improve the reliability of submersible pumps, measures such as leakage protection and overload protection must be installed inside the submersible motor; To improve the operational efficiency of pumps, it is necessary to rely on the application of control technology, and so on. All of these indicate that in order to develop the level of pump technology, it is necessary to simultaneously focus on supporting motors, control technology, and other aspects, comprehensively consider, and maximize the comprehensive level of electromechanical integration.
6. Accelerated utilization of new materials and processes
Over the past decade, the application of new materials and processes has been a major factor driving the development of pump technology. The materials used in pumps, from cast iron to special metal alloys, from typical non-metallic materials such as rubber products and ceramics to engineering plastics, have played a prominent role in solving the corrosion resistance, wear resistance, high temperature resistance and other environmental problems of pumps. At the same time, the application of new technologies enables better application of new materials to the pump components and the entire pump. Some foreign manufacturers have designed and launched pumps made entirely of engineering plastics. Compared to pumps produced with ordinary metal materials, pumps are not inferior in strength and superior in corrosion and wear resistance. For example, using new surface coating and surface treatment techniques can also solve the corrosion and wear resistance problems of pumps. The further development of new materials and the deepening application of new processes will lead to a wider range of applications in the field of pumps.
