Mechanical Seal Fundamentals Session I
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Using engineered composite materials in sealless magnetic drive pumps to eliminate eddy currents and improve reliability
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background - Pump application: This case study is based on an application supplied into a Polysilicon production facility. The purpose of the application is to pump Trichlorosilane (TCS) liquid into the production process ...
Thermal Load Effect on Vibration on a Reactor Feed Water Pump (FWP)
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The Influence of Impeller Wear Ring Geometry on Suction Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Wear rings are a necessary feature of an enclosed centrifugal impeller design. The purpose of the wear ring is to limit the leakage of fluid from the high pressure zone at the impeller outlet to the low pressure region at ...
Eliminating Damage of Retaining Rings by Using Redesigned "Profiled" Keys
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Retaining rings are used to locate pump impellers axially on the shafts of high speed, high pressure Siemens Delaval boiler feed pumps. Upon repairing and refurbishing the inner barrels, the retaining rings were found to ...
Barrier And Buffer Fluid Selection And Considerations For Mechanical Seals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The increased use of pressurized and non-pressurized dual mechanical seals has driven more installations to require the use of barrier and buffer fluids. While some end users have viewed the selection of barrier fluids as ...
High Vibration Analysis of Eddy Current Drum Coupled Motor to a Vertical Centrifugal Pump : Solution Based on EMA, ODS and FEA
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The 35-year old pump station moves up to 43 MGD of raw wastewater to the city’s treatment facility via two 1,500-hp high-capacity pumps for wet weather flows. After the motors were refurbished in 2011, excessive motor ...
Discussion Group P06: Mechanical Seals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Mechanical seals are the most common method of sealing industrial centrifugal pumps and other rotary equipment. Although the basic concepts of a seal is simple, successfully using seals requires an understanding of the ...
Discussion Group P11/Panel Session: Subsea Pumps and Drivers
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Discussion Group P5: Centrifugal Pump Operation, Maintenance and Reliability
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
