Resolving High Vibration On a Vertical Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
There is a single stage vertical pump installed in Acetic Acid area in a petrochemical plant. The unit is vertical high
pressure (HP) reactor feed pump (High speed single stage, 230 kW, 12338 rpm & 3.444 gear ratio) driven ...
Resolving Structural Vibration Issues On a Multi Stage Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
There are three multistage pumps supplied as part of a new project for transporting diesel from one location to another.
Earlier, the transportation of diesel was carried out using trucks for this facility. The availability ...
Steam Turbine Steam Control Valve Failure
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The Wet Gas compressor is one of the most critical assets in a FCCU/RCCU of a oil refinery.
The back pressure steam turbine driver of this compressor faced two failures in the main valve stem of the steam inlet valve. ...
Base Plate Corrosion and Premature Bearing failure in RO Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
On 19th Aug 2017, abnormal noise noticed from RO (Reverse osmosis)
Membrane Feed pump coupling area. Checked the vibration for pump &
motor and found very high vibration at Pump Drive end. The vibration level
at Pump DE ...
Turbomachinery and Pump Vibrations

This group will discuss plant machinery vibration detection, monitoring, and diagnosis, from a Plant O&M point-of-view. All
attendees will be encouraged (but not required) to participate in discussions, and contribute ...
Static and Rotordynamic Analysis of a Plain Annular (Liquid) Seal in the Laminar Regime with a Swirl Brake for Three Clearances
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Annular seals are non-contacting mechanical elements designed to reduce leakage between two areas of differing pressures such as between two impeller stages in a pump. Circumferential fluid rotation inside the annular ...
Surge Exploration Tests and Second Quadrant Characteristic Dynamic Modeling on High Pressure Ratio Compressor (Hprc) Prototype
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
High Pressure Ratio Compressor (HPRC) technology is based on an innovative architecture that combines unshrouded and shrouded
impellers on a single high-speed shaft to achieve pressure ratios and efficiency levels higher ...
Conventional Servo System to Direct Drive Actuators Why Does It Matter?
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper discusses the development of Actuators over a period of time. The purpose of an Actuator (servo system) is to operate steam turbine control valves. With the increasing demand for better control of steam valves ...
