COMPRESSOR ROTOR CRACK CASE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The case study describes rotor crack detection using vibration measurements, documented on real case of Induction Motor driven Compressor Unit. The study highlights the complexity of rotor crack diagnostics as the primary ...
LASER WELDING FOR TURBOMACHINERY ROTOR RESTORATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Laser cladding is gaining acceptance for restoration of turbine and compressor shafts, which has resulted in increased customer demand for laser cladding options. This has increased the number of laser welding suppliers, ...
HYDROGEN-COMBUSTION AND COMPRESSION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Recently, the use of hydrogen-natural gas mixtures as a fuel, but also as a means of storing and transporting hydrogen from surplus electricity as a result of renewable energy production has drawn significant attention. ...
COKING OF GAS TURBINE LUBRICATION OILS AT ELEVATED TEMPERATURES
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Over the last several decades, turbine efficiency has improved significantly, resulting in higher turbine operating temperatures that negatively affect the lubricating oil circulating through the system. Exposure to high ...
IGNITION CHARACTERISTICS OF GAS TURBINE LUBRICATION OILS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Ignition of lubricating oil is a highly undesirable event that is a major safety hazard that could also be incredibly costly. The possibility for lubricant ignition is present in numerous mechanical systems and applications. ...
REALISTIC EXPECTATIONS FROM A UNIQUE PLAN 66A BUSHING DESIGN
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
As crude oil remains the dominant fuel and raw material source for transportation and industry the crude oil pipeline continues to be the preferred crude transportation method across large land masses. Along with this ...
Case Study 39: Pump Vibration due to Reciprocating Engine Balance Gear Issue
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This paper presents the effect of balance gear on a reciprocating engine which drive the crude oil transfer pump that had experienced vibration at one of the offshore platform in Malaysia. Based on this case, it is ...
Chronic high vibration issue of a Condensate Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Chronic high vibration issue was being observed on a critical condensate pump. Although this motor driven pump is a standby unit, however, in case the running pump has a breakdown and the motor pump is unavailable, the ...
TROUBLESHOOTING OF AIR COMPRESSOR HIGH VIBRATION DURING COMMISSIONING STAGE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
An air compressor encountered high vibration issue during its commissioning stage, leading to impeller and casing rub. Inspection performed found dislodged shrink fitted thrust collar, resulting in excessive axial movement ...
High Frequency Acoustic Excitation in Centrifugal Compressor and Adjacent Piping Vibration
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
In a centrifugal compressor, interactions between impeller blades and stationary parts such as diffuser vanes will generate high frequency pressure pulsations. The frequencies of these pulsations, so called “blade passing ...
