Unexpected Vibration on a Centrifugal Compressor Caused by Vibration Probe Support
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
During the commissioning of a Main Air Compressor in an Air Separation Unit, the rotor showed increased radial vibrations at the Non-Drive End probe. The RCA revealed: The vibration resulted from the excitation ...
PNEUMATICALLY ACTUATED CONTROL VALVES IN OIL SYSTEMS: HARDWARE RECOMMENDATIONS AND TUNING CONSIDERATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Well designed and properly commissioned auxiliary systems are crucial to the reliability of rotating equipment. This paper addresses the upfront hardware selection and commissioning of pneumatically actuated control valves ...
Relation between wear ring clearances non-synchronous vibrations in BFW centrifugal pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A de-superheating boiler feed water pump was facing high vibration issue for last 19 years. Pump had been overhauled multiple times in past, but the issue was not resolved. Dominant frequency appearing in vibration spectrum ...
MECHANICAL DAMAGE TO PUMP IMPELLERS CAUSED BY LOW FLOW OPERATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
High- cycle fatigue damage imparted on a BB 5 pump impeller operating at low f low operation points was analyzed via numerical methods. A 1 - way Fluid- Structure interaction approach whereby a t ransient CFD subsequently ...
GAS TURBINE COMPRESSOR INLET AIR FILTERS PERFORMANCE COMPARISON
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Crude Oil Non-Pusher Secondary Seal
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Crude oil pipeline pumps traditionally suffer from seal leakage due to the fretting or wearing of the dynamic O-ring. A new concept secondary seal has been developed to eliminate this fretting occurrence. All major seal ...
AN OVERVIEW OF MACHINERY IN ENERGY STORAGE AND HYDROGEN APPLICATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Decarbonization of electric power infrastructure requires the development of cost-effective, sustainable, and reliable energy storage technologies that are capable of many Megawatts or Gigawatts of output and long storage ...
ELECTROSTATIC DISCHARGE� STG COMPRESSOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Electrostatic discharge (ESD) can cause catastrophic mechanical damage and lower the life span of an asset if not detected early and rectified. Continuous discharge of static electricity can cause micro pitting of bearing ...
Centrifugal Compressor High Sub-Synchronous Vibration (SSV) During Higher Load and Speed
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
In this case study, presence of moisture, contaminant and H2S in process gas has ben discussed that lead to compressor component deterioration and damage. In addition, having situation of idling the compressor close to its ...
Case Study on Additive Manufacturing Metallic and Non-Metallic Pump Impellers for Corrosive Application
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2024-02-27)
At one of our customer/end-user chemical plants in Singapore, they had a problem with frequent replacement of the Hastelloy C impellars casted used in their centrifugal pumps in service with Sodium Hypochlorite application. ...
