compressors handbook 压缩机手册英文版.pdf 方方面面很详细 推荐
PREFACECompressors fall into that category of machinery that is ‘‘all around us’’ but of
which we are little aware. We find them in our homes and workplaces, and in
almost any form of transportation we might use. Compressors serve in refrigeration,
engines, chemical processes, gas transmission, manufacturing, and in just about
every place where there is a need to move or compress gas.
The many engineering disciplines (e.g. fluid dynamics, thermodynamics, tribology,
and stress analysis) involved in designing and manufacturing compressors
make it impossible to do much more than just ‘‘hit the high spots,’’ at least in this
first edition.
This is such a truly broad field, encompassing so many types and sizes of units,
that it is difficult to cover it all in one small volume, representing the work of
relatively few authors. Possibly, more than anything else, it will open the door to
what must follow—a larger second edition.
In compressors, the areas of greatest concern are those parts with a finite life,
such as bearings, seals and valves, or parts that are highly stressed. Treatment of
these components takes up a large portion of the handbook, but at the same time
space has been given to theory, applications and to some of the different types of
compressors.
Much in this handbook is based on empirical principals, so this should serve as
a practical guide for designers and manufacturers. There are also test and analysis
procedures that all readers will find helpful. There should be something here for
anyone who has an interest in compressors.
