Balance Line Flow Monitoring Diagnoses Pump Problem
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Two stage BB1 style pump. Lean Solutions service in Gas Separation Plant. Operating at 6075 gpm with 1470 ft of head. Running Plan 53C for mechanical seals. Recently rebuilt and new seals installed
EFFECT OF FLOW RATE ON THE PERFORMANCE OF A FLOODED-ENDS TILTING-PAD JOURNAL BEARING – EXPERIMENTS AND PREDICTIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Rotating machinery relies on engineered tilting-pad journal bearings (TPJB) to provide static load support with minimal drag power losses, relatively low pad temperatures, and ensuring a rotor dynamic stable operation. End ...
METHODS TO DETERMINE AND SPECIFY ROTODYNAMIC PUMP DYNAMIC ANALYSIS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Vibration caused by resonance is an industry problem for new and retrofit applications that persists due to lack of specification and upfront analysis. To limit the chances of resonant vibration, dynamic analysis of the ...
Fluid Structure Interaction Analysis for Prediction of Centrifugal Compressor Dynamic Stresses
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Centrifugal compressor impellers experience dynamic loading from flow structures generated by upstream and downstream compressor components. This loading can cause high cycle fatigue and ultimately impeller failure if not ...
Understanding Uncertainties in Viscous Pumping Performance Predictions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Accurate predictions of centrifugal pump performance are critical in every fluid industry. Many industries encounter situations where a fluid more viscous than water must be conveyed with a centrifugal pump. As liquid ...
Vibration and NPSHr (NPSH₃), improvement of BB1 two stage pump reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study discusses the impeller redesign of 10 8x15 BB1 two stages Amine pump in a Gas Sweeting Plant in Malaysia. The original pump was supplied in 1996 and after some design changes it had an history of recurring ...
Modern Methods to Detect Degradation in Centrifugal Compressor Performance and Use of Thermodynamic Performance Modelling to Identify Causes
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Detecting degradation in centrifugal compressor thermodynamic performance can be challenging. Machines can operate at different inlet and discharge conditions, different inlet guide vane positions, different speeds and ...
Multi-stage pump vibration caused by excessive wear ring clearance, Improper balancing, rotating stall
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Generally, the centrifugal pump vibration caused by mis-alignment, unbalance or bearing failure. But, I have seen two abnormal vibration phenomena in a multi-stage high pressure pump which has 13th stage impeller.First ...
Pump Tut - Precision Grouting of Turbomachinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Rotating equipment being installed in industrial environments, including refineries and chemical processing plants, are critically aligned with exact tolerances. When in operation, this equipment experiences heavy dynamic ...
Lube Oil Carbonisation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Carbonized particles can get deposited in housing oil seal clearances causing a partial rub like phenomenon. Friction caused due to reduced clearances because of accumulation of carbonized particles leads to shaft thermal ...
