Hydrocarbon Processing - February 2022 - 16
Reliability
SME's mechanical seal was a dismal failure.
It exhibited unexpected outward pumping
action; the leakage rate of noxious paraxylene
was now worse than before.
However,
new lessons
had
been
learned on the spot, and no effort was
made to tweak yesterday's obviously inferior
design idea. In a true brainstorming
session attended by the SME, local engineers
and technicians, the team members
nudged each other towards thinking " outof-the-box. "
An internal, square-threaded,
helical-flight bushing (FIG. 2) took its
inspiration from Archimedes and was
sketched, machined and tested within
24 hr, completely solving the problem of
product leakage. A patent was obtained.
In short: There is a time and a place for
innovative in-house thinking, especially
when time is of the essence. However, at
no time should this thinking disregard
safety. Also, wherever possible, reliability
professionals will benefit from involving
other potential contributors in the deliberative
processes. Finally, we should also
remember that tweaking inferior ideas is
not problem-solving and will rarely substitute
for science-based designs. Archimedes
led the way in 200 B.C.E.
Identifying
potentially
resourceful
employees. Not every employee will be
self-motivated or interested in becoming
a resourceful problem solver, and an employer
can live with that. Still, even during
a job interview a graduating engineer
would be wise to explore his or her projected
role and consider details. Soon after
starting work, the engineer should ask
the manager for a written role statement.
If no such statement is forthcoming, the
engineer may put his or her understanding
on paper and ask the responsible manager
for review, input or concurrence. Unless
agreement on the engineer's role has
been reached, " performance exceeding
expectation " is rather improbable.
Likewise, during the job interview, an
engineer about to graduate should ask
about the training opportunities made
available or endorsed by the prospective
employer. The interviewee's goal must
involve professional growth and learning.
Learning is obviously a two-component
process. While one party offers it and the
other absorbs it, the ultimate benefits are
shared by both.
As an example, a company could identify
a self-motivated employee and ask
this employee if he or she would be willing
to be the custodian of an electronically
stored and searchable engineering library
dealing with turbomachinery, pumps,
gears, shaft couplings, etc. During periodic
performance appraisals and reviews, his
or her progress towards becoming a solid
contributor could be examined.
HEINZ P. BLOCH resides in
Montgomery, Texas. His
professional career commenced in
1962 and included long-term
assignments as Exxon Chemical's
Regional Machinery Specialist for
the United States. He has authored
or co-written more than 780 publications, among
them 24 comprehensive books on practical
machinery management, failure analysis, failure
avoidance, compressors, steam turbines, pumps, and
the just released " Optimized Lubrication, Oil Mist
Technology, and Standstill Protection, " (DeGruyter,
Berlin/Germany, ISBN 978-3-11-074934-2). He holds
BS and MS degrees (cum laude) in mechanical
engineering and is an ASME Life Fellow with life-time
registration as a Professional Engineer in New Jersey.
