Chemical pump applicable analysis
Chemical industry pump best characteristics should be: high quality,
high reliability and high environmental protection performance; Upon
completion of the tasks of chemical medium conveying and for workers'
health. Expect service life cost is lowest; can match with complete set
of chemical equipment organic union into a whole. However, in chemical
manufacturing process, various concrete used conditions and the intended
use also put forward a variety of different requirements to chemical
pump manufacture. In the chemical industry used mechanical product
outstanding features are: mechanical product performance, required
change with be transported chemical substances categories and
properties. Although mentioned here medium sometimes refers to water,
oil or other non harmful substances, However, in most cases chemical
medium refers to is some very "terrifying" chemical raw materials; For
example, some have severe hazardous medium (poisonous, corrosive and
inflammable medium), especially some easy to produce chemical reaction,
corrosion, debaucjed role medium or contains the composition of solid or
gas medium. Multiple chemical medium chemical composition change,
chemical elements ratio change will lead to changes in the chemical
characteristic of medium, cause chemical medium concentration raise or
with special flow properties (such as: diffusible medium, polymer
solution, etc.). Accordingly, often put forward special strict quality
requirements to chemical medium dimethylhydrine (GMP, polymer,
electrolyte, etc.), , but these special strict quality request may be
achieved conveniently through the appropriate chemical pump.
By chemical medium diversity derives diversity of chemical pump
requirements. This makes chemical pump standard system difficult to be a
simple standard system. Compared to other areas, such as household
electric, family heating, water supply, water drainage etc and chemical
scouring or automotive manufacturing field, not only in the production
of products and in the use of products standardization has reached
considerable level. While in chemical production enterprise, chemical
pump standardization work encountered obstacles in terms of technology
and economy.
Where exist
Chemical pump to optimize and improve possible? First
standardization for the production and use of
Chemical pump are useful
and meaningful. But: from the life cycle cost level's perspective, the
most economic standardization should be what? Is a detailed according to
various concrete use situations on long-term optimization
standardization cost-effective? Or a rough standardization
cost-effective? To adopt new technology, new product development, brings
in a long time to recover the standardization investment barriers when
will end? How can damage chemical pump manufacturer and chemical pump
producers either party interests conditions, make both parties to
chemical pump standards have unified cognition? These problems only
through strengthening chemical pump use factory, industry associations
and chemical pump manufacturer dialogue can be answered. Possible
solutions are: from the users' point of view, for example, with
suppliers to establish long-term strategic partnership, In the different
levels of well-defined established within various standardization level
(e.g. chemical pump structure types, suppliers, series, materials,
disposition patterns, etc.) and integrated modular structure.
But the most important is "service life expenses" problem.
Chemical pump
use life potential are not fully dug out. Why will appear this kind of
circumstance? In many possible answers, one answer is everybody
confirmed: because of chemical pump performance parameters of different
requirements, chemical pumps allowed using life, can withstand the load
of the size and so on are not identical. Chemical pump's purchase cost,
installation fee, chemical pump working energy consumption costs and
maintenance costs is relatively easy to accounting out. But chemical
pump maintenance fee estimate relatively difficult to determine: because
chemical pump failure and possible damage is not decided itself, it is
restricted by ever-chaging transported chemical medium, special
applicable conditions. Using mastered, certain chemical pump experience,
to estimate another chemical pump maintenance fee have great
limitations, estimation results also is only probable, broad-brush
estimate.
