High Temperature Twin Screw Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
High temperature applications present many engineering problems. Thermal growth of piping and vessels, coupled with typically lower viscosities at high temperature, has made centerline mounted centrifugal pumps the primary ...
Pump Impeller Lifetime Improvement Through Visual Study Of Leading-Edge Cavitation
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper describes the successful application of cavitation flow visualization to redesign the impeller of an 8.5-MW (11,400 hp) high energy double suction single stage boiler feedpump. Dual purpose of the investigation ...
Methods Of Investigation And Solution Of Stress, Vibration, And Noise Problems In Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
This tutorial discusses mechanical problems that occur in pumps and their systems, and how pump users can best detect and solve these problems. The answers to pump operational or reliability problems are often not obvious, ...
Pump Reliability Improvements Through Effective Seals And Coupling Management
(Texas A&M University. Turbomachinery Laboratories, 1998)
Market pressures are demanding cost reductions in the process industries. Most operators are seeking to achieve substantial savings through reductions in the maintenance and “real” operating costs of centrifugal pumps of ...
Reciprocating Pump Dynamic Concepts For Improved Pump Operations
(Texas A&M University. Turbomachinery Laboratories, 1998)
In order to ensure safe, reliable, efficient and cost effective operation of reciprocating pumps, pump dynamics should not be ignored. Pump problems due to dynamics are often difficult to diagnose and solve. Dynamic problems ...
Shaft Alignment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Proper alignment of rotating equipment has long been recognized as a prerequisite to safe, reliable operation. Achieving proper alignment, however, involves much more than merely adjusting the machines so that the shafts ...
Testing And Field Performance Of A High Duty NGL Pipeline Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
An improved multiple seal design was developed for a critical high performance pipeline pumping application with a difficult range of conditions. The pumps are four stage construction, with a 700 hp electric motor and ...
Failure Analysis and Troubleshooting Mechanical Seals and Systems
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
Any piece of equipment which has been in operation has a story to tell. The condition of the equipment can uncover a rich set of information which reveals the way the equipment was operated, maintained, and eventually, ...
Failure Analysis and Troubleshooting Mechanical Seals and Systems
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Any piece of equipment which has been in operation has a story to tell. The condition of the equipment can uncover a rich set of information which reveals the way the equipment was operated, maintained, and eventually, ...
API 682 Arrangement 2 Configurations - Considerations For Outer Seal And Support System Design
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
API 682, now in its 4th Edition, has made a concerted effort to accurately define and distinguish between different types of seal configurations available under the designation of ‘Arrangement 2’, including 2CW-CW, 2CW-CS, ...
