Elements Of Mechanical Equipment Life-Cycle Cost Analysis.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Mechanical equipment typically comprises 25 to 35 percent of total capital investment in a new plant project. This percentage usually increases in upgrade, revamp, or debottleneck project. For lump sum turnkey projects, ...
"Do As I Say" (The Effects Of The Process On Turbomachinery Reliability).
(Texas A&M University. Turbomachinery Laboratories, 2001)
This tutorial examines the primary cause of lower than expected reliability in turbomachines, the effect of the process on machinery component life. Over 95 percent of the rotating equipment installed in any refinery, ...
The New Fifth Edition Of API 618 For Reciprocating Compressors - Which Pulsation And Vibration Control Philosophy Should You Use?
(Texas A&M University. Turbomachinery Laboratories, 2001)
The proposed Fifth Edition of API 618 (“Reciprocating Compressors for Petroleum, Chemical, and Gas Industry Services”) incorporates significant changes in the section concerning pulsation and vibration control. There are ...
Gas Turbine Performance Deterioration.
(Texas A&M University. Turbomachinery Laboratories, 2001)
With privatization and intense competition in the utility and petrochemical industry, there is a strong incentive for gas turbine operators to minimize and control performance deterioration, as this directly affect ...
Coupling Interface Connection.
(Texas A&M University. Turbomachinery Laboratories, 2001)
In rotating equipment, torque is usually transmitted from shafts to coupling hubs through keys, splines, friction, or a combination of these. Not covered in this tutorial are applications where the rotating equipment has ...
Maintenance And Online Diagnostics On Gearboxes In The Petrochemical Industry.
(Texas A&M University. Turbomachinery Laboratories, 2001)
As a result of cost reductions, there are fewer and fewer gear specialists in compressor and turbine companies, as well as in the maintenance groups of users. Therefore, these groups rely on the gear manufacturer’s expertise ...
Proven Methods For Evaluating The Health Condition Of Piston Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Very often, especially in the oil, gas, and chemical industry, the efficiency of a plant depends on the reliability of reciprocating compressors. Telemonitoring systems can help to make the shutdowns and outages for ...
Application Of Foil Bearings To Helium Turbocompressor.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Hydrodynamic gas-lubricated foil bearings are ideal for machinery that operates at high speed or in extreme-temperature environments. As motors and generators run at higher speeds with more torque capacity, the need for ...
Eliminating A Rub-Induced Startup Vibration Problem In An Ethylene Drive Steam Turbine.
(Texas A&M University. Turbomachinery Laboratories, 2001)
A 16 megawatt ethylene drive steam turbine built in 1973 experienced rub related startup vibration problems for many years. The turbine would lock into a rub as it accelerated through the rotor’s first critical speed causing ...
Electric Power Supply Instabilities Exciting Torsional And Lateral Vibrations Of An Integrally Geared Turbocompressor.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Commissioning and operating turbomachinery often create surprises especially with respect to vibration. Often not all the conditions are known under which these highly-efficient turbomachines have to operate. This case ...
