Future development prospect of gear pump industry technology
Future development prospect of gear pump industry technology
Enter the information age today, gear pump designers have already used computer technology to product development and design (such as the use of CAD) greatly improve the speed of design itself, shorten the cycle of gear pump technology design.In the manufacturing process, the manufacturing technology represented by CNC CAM has been deeply involved in the production of gear pump.However, from the recent domestic situation, CNC CAM technology is mainly used in the production of batch products.For the production of single piece or small batch, CAM technology has not been widely implemented in the gear pump industry at present, and the production of single small batch is still dominated by traditional production equipment.
Standardization and modularization of products
At the same time of product diversification, pump as a general product, the total volume is still huge.In the market, in addition to the emergence of technical competition, product price competition, especially generic product price competition is an inevitable trend.In the trend of product diversification, it is necessary to realize the competitive advantage of product price, improve the standardization degree of product parts and realize the modularization of product parts.After realizing the modularization of many parts, the product can be diversified through the combination of different modules or changing the characteristics of individual parts.At the same time, only when the degree of standardization of parts is improved can it be possible to actually scale the production of parts based on product diversification, so as to reduce the production cost of products and form product price competitive advantage, and further shorten the product delivery cycle on the basis of product diversification.
Over the past decade, the use of new materials and processes has been a major factor driving the development of pump technology.Gear pump materials from cast iron to special metal alloy, from rubber products, ceramics and other typical non-metallic materials to engineering plastics, in solving the pump corrosion resistance, wear resistance, high temperature and other environment have played a prominent role.At the same time, the application of new technology, and better use of new materials in the gear pump parts and even the whole gear pump.If some foreign manufacturers have been designed and introduced the pump made of engineering plastics.Compared with the production of general metal materials in the strength of the pump is not inferior, in the corrosion resistance and wear better.For example, the use of new surface coating technology and surface treatment technology, the same can solve the problem of gear pump corrosion and wear resistance.With the further development of new materials and the application of new technology, the application in the pump field will be more extensive.
Gear pump intrinsic characteristics of the promotion and pursuit of external characteristics
The intrinsic characteristics of the so-called gear pump refers to the inherent characteristics of products including product performance, parts quality, complete machine assembly quality, appearance quality, etc., or simply called quality.At this point, is the current many pump manufacturers are concerned about is also efforts to improve, improve the aspect.In fact, we can find that many products fail to achieve the factory inspection effect after they are tested in the factory and sent to the use unit for operation. Problems such as overload, increased noise, unsatisfactory use or reduced life are encountered.And the pump in the actual operating point or operating characteristics, we call the external characteristics of the pump or system characteristics.
Technicians often spend a lot of time in product design to improve the efficiency of a product by one percent.If the gear pump operation deviates from the design point, the actual operating efficiency is far less than one percent.Now, gear pump manufacturers at the same time for users including frequency conversion control equipment and complete set of equipment, in fact, has been involved in the pursuit of external characteristics of the gear pump.On this basis, and then pay attention to the centralized control system of the pump, improve the efficiency of the entire gear pump and gear pump station, is in the pursuit of external characteristics of the gear pump on the next level.
