Improvements In Bearing Life Using New Sealing Technology
(Texas A&M University. Turbomachinery Laboratories, 2005)
As many as 91 percent of all rolling element bearings fail to achieve their calculated theoretical lifetimes. One of the primary reasons for this failure is contamination of the lubricants. Past practice for protecting ...
A New Concept In Mechanical Seal Cooling - The Integral Heat Sink
(Texas A&M University. Turbomachinery Laboratories, 2005)
Thermally induced failures have long since plagued mechanical seal users. Over the years these failures have led to the development of different flush plan and seal design features that are used to increase heat transfer ...
Practical Design Against Pump Pulsations
(Texas A&M University. Turbomachinery Laboratories, 2005)
One of the foremost concerns facing pump users today is that of pulsation problems in their piping systems and manifolds. In cases where a fluid excitation is coincident with both an acoustic resonance and a mechanical ...
Material Selection For Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 2005)
Mechanical seals are used throughout industry to minimize or eliminate leakage in centrifugal pumps, mixers, and other rotating equipment. The ability of a mechanical seal to meet its performance objectives depends upon a ...
A New Unique High Pressure Pump System
(Texas A&M University. Turbomachinery Laboratories, 2005)
The combination of a 16 inch Pitot tube pump with a switched reluctance motor represents a significant development in the field of high-pressure pumping. A field proven Pitot tube pump design has been mechanically integrated ...
Impeller Rerate To Reduce Hydraulically Generated Vibration
(Texas A&M University. Turbomachinery Laboratories, 2005)
The vibration of centrifugal pumps, running at both best efficiency point (BEP) and at low flow, is of interest to both pump designers and users. This vibration is responsible for the poor seal and bearing life and reduced ...
Upthrust Problems On Multistage Vertical Turbine Pumps
(Texas A&M University. Turbomachinery Laboratories, 2005)
Vertical turbine pumps are designed to operate with the pump shafts in tension (downthrust). Most pump and motor manufacturers caution users to not operate the vertical turbine pumps at conditions that result in “upthrust.” ...
Active Lift Seal Technology Impacted On Water Injection Services
(Texas A&M University. Turbomachinery Laboratories, 2005)
Increasing environmental awareness and the ongoing need for improved reliability has seen an increase in the number of water reinjection installations, both onshore and offshore, and in particular in recent years, the use ...
Basic Pump Rotordynamic Analysis And Specifications
(Texas A&M University. Turbomachinery Laboratories, 2005)
