Author Description

Process Machinery Handbook: For Field Personnel, Decision Makers, and Students equips newcomers and seasoned professionals with essential insights into the diverse world of process machinery, empowering them to understand unique performance characteristics, common failure modes, and effective strategies for enhancing reliability in their operations. Any professional working at a production site for any length of time knows that process machinery comes in a wide range of designs and sizes, but not all process machines are considered equal. Some machines are more critical to the process than others, some are small, some are very large, some spin fast, and some turn relatively slowly. The great diversity in their construction and application can be daunting to those new to the industry and sometimes even challenge machinery veterans. There are many common concepts that apply to all equipment types, but each equipment category has its own unique application and performance characteristics, including cavitation in liquid handling pumps, surging in centrifugal gas compressors, rotor instability in high-speed centrifugal compressors, and the effect of the compression ratio on a reciprocating compressor's the discharge temperature. It is also essential for users to understand how and why different types of machinery fail, keeping in mind that the common failure modes differ greatly between rotating machinery types. We know that by addressing the common types of failure modes associated with each machine type, we can achieve significant improvements in their reliability. The first step in organizing an effective machinery reliability program is committing to performing failure analyses and gathering failure statistics. These activities will help users learn how and why their machines are failing. The next step is to continuously modify machines, processes, and methods to avoid common failures.
