Maximizing An Ethylene Plant's Turbomachinery Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The ethylene plant in DuPont's major petrochemical complex
in Orange, Texas was designed and built in the late 1960s,
using the latest proven technology of that period. From plant
startup in 1967 to 1981, there were ...
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 ...
Table of Contents for the Proceedings of the 6th International Pump Users Symposium
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
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 ...
Practical Applications Of Rotordyanmics, Bearing Design, Mechanical Analysis, And Vibration Diagnostics To Design Problems of Rotating Machinery in Operation
(Texas A&M University. Turbomachinery Laboratories, 1989)
A large majority of today's existing high performance rotating machinery in operation was manufactured and installed long before the advent of powerful design tools in the complex areas of rotor system dynamics and stability ...
Heavy Shell Castings Design/Operation And Repairs Criteria.
(Texas A&M University. Turbomachinery Laboratories, 1989)
Unless the utility industry is prepared as a whole to commit a very large dollar amount to the purchase of new heavy wall castings for turbine casings and valve chests, the use of the art of repair for existing castings ...
Reapplication Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The reapplication of equipment can be attractive and rewarding when the proper situation warrants. The main factors that encourage consideration of this path can include simple economics, convenience, or possibly a more ...
