Improvement prospect and direction of chemical pump


The characteristics of chemical pumps should be: high quality, high reliability and high environmental performance; It is beneficial to the health of workers while completing the task of transporting chemical media; The expected service life cost is low; It can be organically integrated with the whole set of chemical equipment. However, in the process of chemical production, various specific use conditions and purposes put forward different requirements for the manufacture of chemical pumps.

The outstanding feature of mechanical products used in the chemical industry is that the performance and requirements of mechanical products change with the type and nature of the chemical medium being transported. Although the medium mentioned here sometimes refers to water, oil or other non harmful substances; However, in most cases, chemical medium refers to some very "terrible" chemical raw materials; For example, some media with serious hazards (toxic, corrosive and flammable media); In particular, some mediums that are easy to produce chemical reactions, have corrosion and erosion effects, or solid or gas mediums containing the above components.

The change of chemical composition and the change of chemical element ratio in multi-element chemical medium will lead to the change of chemical medium properties; The concentration of chemical medium is increased or it has special flow performance (such as diffusive medium, polymer solution, etc.). Therefore, strict quality requirements are often put forward for the purity of chemical media (GMP, polymer, electrolyte, etc.), and these strict quality requirements can be easily realized through appropriate chemical pumps. The diversity of chemical pump requirements is derived from the diversity of chemical media. This makes it difficult for the chemical pump standard system to become a simple standard system. Compared with other fields, such as household appliances, household heating, water supply, drainage and other fields, as well as chemical refining or automobile manufacturing, standardization has reached a considerable level not only in the production of products but also in the use of products. However, in chemical production enterprises, the standardization of chemical pumps has encountered obstacles in terms of technology and economy.
Now let's talk about the direction of chemical pump optimization and improvement:

First of all, standardization is very helpful and meaningful to the production and use of chemical pumps. However, from the perspective of life cycle costs, what should economic standardization look like? Is it a detailed standardized calculation of long-term optimization based on various specific use cases? Or is it a rough standardized summation? When will the barriers to the adoption of new technologies and the development of new products, which will take a long time to recover, end? How can we make both parties have a unified understanding of the standards of chemical pumps without harming the interests of either chemical pump manufacturer or chemical pump user? These questions can only be answered by strengthening the dialogue among chemical pump users, industry associations and chemical pump manufacturers. Possible solutions are: from the perspective of users, such as establishing long-term strategic partnership with suppliers; Establish different standardized levels (such as the structure type, supplier, series, materials, configuration mode, etc. of chemical pumps) and integrated modular structures in different levels that are clearly defined. But the important issue is the "service life cost".

The potential of chemical pump service life has not been fully exploited. Why does this happen? Among many possible answers, there is one answer that everyone is sure of: due to the different requirements for the performance parameters of chemical pumps, the allowable service life of chemical pumps, the size of the load they can bear, etc. are different.
The purchase cost, installation cost, energy consumption cost and maintenance cost of chemical pumps are relatively easy to calculate. However, it is relatively difficult to estimate the maintenance cost of chemical pumps: because the failure and possible damage of chemical pumps are not determined by the pump itself, they are often subject to the ever-changing chemical media being transported and special use conditions. Using the mastered experience of one chemical pump to estimate the maintenance cost of another chemical pump often has great limitations, and the estimated result can only be a rough estimate.
