Pump Wisdom Explore key facets of centrifugal pump ownership,
installation, operation, and troubleshooting The Second Edition of
Pump Wisdom: Essential Centrifugal Pump Knowledge for Operators and
Specialists delivers a concise explanation of how pumps function,
the design specifications that must be considered before purchasing
a pump, and current best practices in lubrication and mechanical
seals. Readers will encounter new startup and surveillance tips for
pump operators, as well as repair versus replacement or upgrade
considerations for maintenance decision makers, new condition
monitoring guidance for centrifugal pumps, and expanded coverage of
operator best practices. This latest edition of Pump Wisdom:
Essential Centrifugal Pump Knowledge for Operators and Specialists
includes expanded coverage of areas critical to achieving
best-in-class pump reliability, including commonly encountered
issues and easy-to-follow instructions for getting centrifugal
pumps to operate safely and reliably. This book also provides:
Comprehensible and accessible explanations of pump hydraulics
Simple explorations of the mechanical aspects of pumps with
coverage of bearings, seals, impeller trimming, lubricant
application, and more Safety tips and instructions for centrifugal
pumps Perfect for chemical, petroleum, and mechanical engineers,
Pump Wisdom: Essential Centrifugal Pump Knowledge for Operators and
Specialists is also an ideal resource for operators, managers,
purchasing agents, machinists, reliability technicians, and
maintenance workers in water and wastewater plants.
Process machines are critical to the profitability of processes.
Safe, efficient and reliable machines are required to maintain
dependable manufacturing processes that can create saleable,
on-spec product on time, and at the desired production rate. As the
wards of process machinery, we wish to keep our equipment in
serviceable condition. One of the most challenging aspects of a
machinery professional or operator's job is deciding whether an
operating machine should be shut down due to a perceived problem or
be allowed to keep operating. If he or she wrongly recommends a
repair be conducted, the remaining useful machine life is wasted,
but if he or she is right, they can save the organization from
severe consequences, such as product releases, fires, costly
secondary machine damage, etc. This economic balancing act is at
the heart of all machinery assessments. Troubleshooting is part
science and part art. Simple troubleshooting tables or decision
trees are rarely effective in solving complex, real-world machine
problems. For this reason, the authors want to offer a novel way to
attack machinery issues that can adversely affect the reliability
and efficiency of your plant processes. The methodology presented
in this book is not a rigid "cook book" approach but rather a
flexible and dynamic process aimed at exploring process plant
machines holistically, in order uncover the true nature the problem
at hand.
When installed and operated properly, general purpose steam
turbines are reliable and tend to be forgotten, i.e., out of sound
and out of mind. But, they can be sleeping giants that can result
in major headaches if ignored. Three real steam turbine undesirable
consequences that immediately come to mind are: * Injury and
secondary damage due to an overspeed failure. An overspeed failure
on a big steam or gas turbine is one of the most frightening of
industrial accidents. * The high cost of an extensive overhaul due
to an undetected component failure. A major steam turbine repair
can cost ten or more times that of a garden variety centrifugal
pump repair. * Costly production loses due an extended outage if
the driven pump or compressor train is unspared. The value of lost
production can quickly exceed repair costs. A major goal of this
book is to provide readers with detailed operating procedure aimed
at reducing these risks to minimal levels. Start-ups are
complicated by the fact that operators must deal with numerous
start-up scenarios, such as: * Commissioning a newly installed
steam turbine * Starting ups after a major steam turbine repair *
Starting up a proven steam turbine after an outage * Overspeed trip
testing It is not enough to simply have a set of procedures in the
control room for reference. To be effective, operating procedures
must be clearly written down, taught, and practiced until they
become habit.
The perfect primer for anyone responsible for operating or
maintaining process gas compressors. Gas compressors tend to be the
largest, most costly, and most critical machines employed in
chemical and gas transfer processes. Since they tend to have the
greatest effect on the reliability of processes they power,
compressors typically receive the most scrutiny of all the
machinery among the general population of processing equipment. To
prevent unwanted compressor failures from occurring, operators must
be taught how their equipment should operate and how each
installation is different from one another. The ultimate purpose of
this book is to teach those who work in process settings more about
gas compressors, so they can start up and operate them correctly
and monitor their condition with more confidence. Some may regard
compressor technology as too broad and complex a topic for
operating personnel to fully understand, but the author has
distilled this vast body of knowledge into some key, easy to
understand lessons for the reader to study at his or her own pace.
This groundbreaking new work is a must-have for any engineer,
operator, or manager working with process compressors. The main
goals of this book are to: Explain important theories and concepts
about gases and compression processes with a minimum of mathematics
Identify key compressor components and explain how they affect
reliability Explain how centrifugal compressors, reciprocating
compressors, and screw compressors function. Explain key operating
factors that affect reliabilityIntroduce the reader to basic
troubleshooting methodologies Introduce operators to proven field
inspection techniques Improve the confidence of personnel operating
compressors by teaching them the basics of compressor theory
Improve compressor reliability plantwide by teaching operating and
inspection best practices Improve communication between operating
and supporting plant personnel by providing a common vocabulary of
compressor terms Help processing plants avoid costly failures by
teaching operators how to identify early compressor issues during
field inspections
