Pump Guy Mailbag: Certified Pump Curve Problems Mr. Bachus, I am a PE, at an engineering firm in New England. I have been working more …
In my inbox was a message from Phil J., a name I couldn’t immediately place. The email subject was a question, “When is a pump problem not a pump problem?” I opened the message and read the answer, “When it is a pipe problem!”
What are the mysterious, continuous, undetermined, recurring vibrations plaguing industrial process pumps? The answer is simple.
The instrumentation technician is a better friend to the pump reliability engineer than the vibration analyzer or the CMMS program. I’ve written these words before in more than one “Pump Guy” article, but rarely does the instrumentation tech know the influence he exercises.
At our latest Pump Guy Seminar, I got to chatting with one of the attendees to get his perspective on the content of the training. While he said the material covered was very good and would certainly be helpful to him in his role—he was a maintenance tech—it was also a frustrating reinforcement of something he already knew.
Process pumps need instrumentation. When the velocity, flow, and pressure are not what they should be, the alteration stresses the pump. This is the reason I’ve said before that the instrumentation technician is a better friend to the Pump Reliability Engineer than the vibration analyzer or the CMMS program.
Flow Control presented yet another successful Pump Guy Seminar last week in Lake Charles, La. Among the core themes of the presentation was establishing pump failure as a signal of a problem in one of three key areas: Design/Application, Operation and/or Maintenance.
