The characteristics of chemical pumps should be: high quality, high reliability, and high environmental performance; While completing the task of transporting chemical media, it is also beneficial for the physical health of workers; Low expected service life cost; It can be organically integrated with the entire set of chemical equipment into a whole. However, in the chemical production process, various specific usage conditions and purposes have put forward various requirements for the manufacturing of chemical pumps.
The prominent feature of mechanical products used in the chemical industry is that the performance and requirements of mechanical products vary with the type and nature of the chemical medium being transported. Although the medium mentioned here sometimes also refers to water, oil, or other non hazardous substances; However, in most cases, chemical media refer to some very “terrifying” chemical raw materials; For example, some media with serious hazards (toxic, corrosive, and flammable media); Especially for media that are prone to chemical reactions, corrosive, and erosive, or solid or gaseous media containing the aforementioned components.
Changes in chemical composition and chemical element ratios in diverse chemical media can lead to changes in the properties of the chemical media; Causing an increase in the concentration of chemical media or having special flow properties (such as diffusive media, polymer solutions, etc.). Therefore, particularly strict quality requirements are often put forward for the purity of chemical media (GMP, polymers, electrolytes, etc.), which can be easily achieved through suitable chemical pumps. The diversity of chemical media has derived the diversity of requirements for chemical pumps. This makes it difficult for the chemical pump standard system to become a simple standard system. Compared to other fields, such as home appliances, home heating, water supply, drainage, etc., as well as chemical refining or automotive manufacturing, standardization has reached a considerable level not only in product production but also in product use. In chemical production enterprises, the standardization of chemical pumps has encountered obstacles in terms of technology and economy.
Let’s talk about the direction of optimizing and improving chemical pumps below:
Firstly, standardization is very helpful and meaningful for the production and use of chemical pumps. But from the perspective of life cycle costs, what should economic standardization look like? Is it a detailed standardized long-term optimization calculation based on various specific usage situations? Or is it a rough standardized calculation? When will the hindrance of standardized investments that can only be recovered over a long period of time due to the adoption of new technologies and the development of new products end? How can we achieve a unified understanding of the standards for chemical pumps on both sides without harming the interests of either the chemical pump manufacturer or the chemical pump user? These questions can only be answered by strengthening dialogue between chemical pump users, industry associations, and chemical pump manufacturers. Possible solutions are: from the perspective of users, such as establishing long-term strategic partnerships with suppliers; Establish different levels of standardization within clearly defined levels (such as structural types, suppliers, series, materials, configuration methods, etc.) and integrated modular structures for chemical pumps. But what is important is still the issue of “service life cost”.
