Grouting Of Small Pump Baseplates? Is It Worth It?
(Texas A&M University. Turbomachinery Laboratories, 2004)
For pump installation most experts recommend installing conventional metallic baseplates on concrete foundations and securing them to the foundation with a combination of anchor bolts and epoxy grout. Many papers have been ...
Magnetic Fluid Seal System For Control Of Pump Fugitive Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Pump fugitive emissions can now be controlled to near zero levels by the use of a simplified dual seal system. A magnetic fluid secondary seal traps any vapors that leak past the primary mechanical seal. This arrangement ...
Shaft Sizing For Multistage Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
For proper sizing of pump shafts, many criteria need to be considered such as stress, deformation, and rotordynamics. The authors try to shed more light on these areas in order to ensure economic, safe, and reliable pump ...
Finite Element Transient Thermal Analysis Of An Axially Split Horizontal Multistage Pump
(Texas A&M University. Turbomachinery Laboratories, 1999)
Often the industrial power generation market specifies that boiler feedpumps must be capable of withstanding thermal transient conditions when operating in boiler feed service. A thermal transient analysis was performed ...
Material Problems And Solutions - A Metallurgical Perspective
(Texas A&M University. Turbomachinery Laboratories, 1996)
Pumps are an essential component of most industrial processes. Reliability is a major concern of pump manufacturers and users, since unexpected shutdowns can have serious and costly implications, including loss of production. ...
A Case Study: Unusual Problems Discovered During The Rerate Of 2800 HP Boiler Feed Water Pumps And Turbines
(Texas A&M University. Turbomachinery Laboratories, 1996)
The boiler feedwater system in a world scale ethylene plant utilized horizontal multistage barrel case pumps and single stage impulse type steam turbine drivers with mechanical governors. As part of a major debottlenecking ...
A New Method For Secondary Containment Of Emissions From Primary Seals
(Texas A&M University. Turbomachinery Laboratories, 1998)
Recent industrial advances in secondary containment methods have increased the role of secondary containment systems in environmental corporate strategies aimed at lowering the risks associated with leakage from primary ...
Cavitation And Recirculation Troubleshooting Methodology
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
High reliability and large rangeability are required of pumps in existing and new plants which must be capable of reliable on-off cycling operations and especially low load duties. The reliability and rangeability target ...
Controlling Emissions To Atmosphere Through The Use Of A Dry-Sliding Secondary Containment Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Increasing concern over the emission of hazardous compounds to the atmosphere has led to stricter regulations regarding the acceptable amount of leakage from pumps. This is forcing the users and manufacturers of pumps and ...
Canned Motor And Magnetically Coupled Pumps - Applications, Operations, And Maintenance In A Chemical Plant
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The environmental requirements that drive chemical producers to move more and more to the use of the “sealless” pump are described. The development of the sealless pumps in the European industrial community and their ...
