Rotordynamic And Dry Running Behavior Of A Full Scale Test Boiler Feed Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Excessive rotor vibrations are one of the leading causes of damage to pump components, particularly to bearings, shaft seals, and premature wear of labyrinth surfaces. Under an EPRI contract which was awarded to Sulzer in ...
Design Of Magnetically Driven Chemical Pump To Fit ANSI B73.1 Dimensions Using A Semiopen Impeller
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
A magnetically driven sealless chemical pump was developed that employs high torque rare-earth magnets. Utilizing a semiopen impeller configuration, the pump was designed to fit into the ANSI B73.1 standard dimensional ...
And What Of The Future?
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
A User's View Of Sealless Pumps - Their Economics, Reliability, And The Environment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Numerous surveys have shown that the shaft seal is the dominate root cause of failure for the chemical process pump. These component failures are attributed with the lion’s share of the pump maintenance cost. Moreover, ...
Root Cause Analysis Of Five Costly Centrifugal Pump Failures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Machinery failure analysis and troubleshooting are often pursued in a somewhat haphazard, unstructured fashion. This paper presents a novel, proven, and well focused approach which can quickly lead to the root cause ...
Considerations In Hot And Cold Alignment And Couplings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Hot and cold alignment techniques are addressed, with graphical plotting of reverse dial indicator alignment maps. An alignment program with a two sets of data for cross checking and suggested proper tooling and procedures ...
Magnetically Driven Centrifugal Pumps Eliminating Seal Problems In Refinery And Chemical Processing Plant Equipment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Centrifugal pump design plays an essential role in the safe operation of any refinery or chemical processing plant. In analyzing the performance of centrifugal pumps, pump operating time to failure is almost always limited ...
Pump Rotor Critical Speeds Diagnosis And Solutions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Delmarva Power Indian River Power Station’s Unit 4 has had boiler feed pump reliability problems since startup in 1980. The pump has been rebuilt nine times with post overhaul operability ranging from 30 minutes to 16 ...
New Developments In Standby Seals For Applications For Environmental Sensitive Duties
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Over the years, close attention has been paid in process facilities to the pumping of light hydrocarbons. Leakage of these products can and do cause environmental and health threatening situations. Since attention has been ...
Design, Construction, And Applications Of Magnetically Coupled Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Since the early 1970s, the environmental protection has become more and more important when designing industrial plants and, today, this question is always first in any public discussion. Thus, the engineering profession ...
