Vibration Assessment Of Variable Speed Vertically Mounted Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Analytical and experimental assessments of the vibration characteristics are described for two 700 hp, vertically mounted centrifugal service water pumps following their conversion from fixed speed to variable speed ...
Centrifugal Pump Hydraulics For Low Specific Speed Applications
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The hydraulic coverage in the low specific speed region has been ignored by most centrifugal pump manufacturers because of unfavorable hydraulic characteristics, and manufacturing obstacles such as small, difficult to cast ...
Dry Start Bearing For Vertical Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Compound bearings made of PTFE and synthetic rubber were developed for vertical pumps to startup without initial lubricating water. Through various experiments, they were clarified to be superior to any other bearings of ...
Heat Transfer In Mechanical Seals
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Numerous studies have shown that mechanical seal reliability is related to the state of the fluid between the seal faces. In turn, the fluid state depends on the seal face temperature. Unfortunately, calculating the seal ...
Reciprocating Pump Valve Design
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The working mechanism and life expectancy of automatic pump check valves, which are important for the operational safety of oscillating displacement pumps, are closely examined. A calculation process for the determination ...
Rolling Bearings In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The primary considerations for the selection and application of rolling bearings in centrifugal pumps are discussed. These considerations apply to both the pump manufacturer and the pump user. The various types of bearings ...
The Development Of An Advanced Mechanical Seal For Slurry
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The development of a novel mechanical seal specifically aimed at applications where the sealed medium contains a significant proportion of suspended solids is discussed. It follows the project in detail from the initial ...
Inspection And Quality Control
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Petrochemical companies are confronted daily with the need for greater equipment reliability and a decrease in the overall maintenance cost. The philosophy and objectives behind inspection and quality control of rotating ...
Design, Construction And Test Of Magnetic Bearings In An Industrial Canned Motor Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The replacement of conventional bearings with magnetic bearings in a canned motor pump is discussed. The primary objective was the development of a long life bearings for canned motor pumps. The research project was a joint ...
Vibration Behavior Of Heber Hydrocarbon Booster Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The Heber Project is a demonstration power plant which operates on a binary cycle using a geothermal heat source. It has four booster pumps in the hydrocarbon working fluid circuit. These pumps have had a long history of ...
