This article is a continuation of Part 1, which discussed the evaluation of two damaged wear rings from centrifugal pump applications—a stationary (inner) ring and a rotating (outer) ring.
Pumps handicapped by not using best available technology
Pump lubrication deficiencies are often denied, and the outstanding reliability performance of oil mist is vastly underreported.
Analyze machinery failure data with a spreadsheet
Some basic, yet insightful, machinery reliability tracking tools are introduced here that can be developed with common spreadsheet applications, such as Excel.
Specify the pressure drop of a vent silencer
Industrial facilities, such as refineries and petrochemical plants, have many systems and equipment that must relieve steam or gases through discharge piping to the atmosphere to avoid overpressure and protect the installation.
Address measurement uncertainty in pipelines and storage
How would you measure the volume of a can of soup? The height should work, but what about diameter? Or, you can possibly just trust what the manufacturer has told you on the label.
Benefits of close-coupled flush rings
The chemical industry uses flush rings for diaphragm seals.
