your facility. A "ready-to-travel" status supports overnight
response to critical-need situations worldwide for the gas pipeline,
power generator, paper, and process industries.
Services
Owners, operators, and suppliers of reciprocating machinery, piping,
turbomachinery, and associated plant systems can take advantage of
our machinery vibration engineering services that include:
-
Machinery Torsional Dynamics: Shaft, couplings, and gear damage
occur when torsional critical speed coincides with strong
excitation.
-
Fan and Duct Dynamics: SwRI engineers identify critical speed,
foundation resonance, disk wobble, thermal bow, impeller cracking,
unstable drives, rotating stall, and blade vibration.
-
Rotordynamic Analysis: SwRI applies state-of-the-art rotordynamics
tools to diagnose and rectify problems with rotating machinery and
to design new equipment. Lateral critical speeds analysis includes
bearings, stiffness and damping coefficients, unbalance response,
rotor instability, and mode shapes. Transient torsional speed
analysis includes synchronous motor start-ups and cumulative fatigue
damage.
-
Reciprocating Compressor Foundation Integrity: SwRI predicts
foundation loads, the stresses they cause, and the potential for
concrete cracking. Alternative approaches are analyzed to control
stresses and cracking.
-
Reciprocating Compressor Field Support: A full range of field
engineering services are available to measure, analyze, and correct
problems affecting safe, reliable reciprocating compressor
operation.
-
Reciprocating Pump Support Services: We offer a full range of field
engineering services to measure, analyze, and correct problems
affecting safe, reliable reciprocating pump operation.
-
Flow-Induced Vibration and Noise: SwRI experience includes solving
flow-induced vibration and noise problems with safety relief valves,
heat exchangers, heat recovery steam generators, and flow splitters.
-
Centrifugal Pump Problem Diagnosis: We can help you with a line of
services for eliminating centrifugal pump problems, such as
vibration, pulsation, and cavitation, as early in the design and
operating stage as possible.
-
Crankshaft Strain in Large Integral Reciprocating
Engine/Compressors: To avoid reciprocating engine or compressor
crankshaft failures, SwRI monitors bearing alignment and measures
and records dynamic strain in the root of the crank web.
-
Finite Element Dynamic Analysis: Finite element analysis complements
field problem solving and failure analyses services to diagnose
causes and develop design solutions.
-
Root Cause Failure
Analysis: Investigations combine the
technologies of fractographic examination, materials evaluation,
structural analysis, dynamic loading, thermal environment
prediction, fracture mechanics analysis, and frequency testing.
-
Troubleshooting Turbomachinery Operating and Installation Problems:
SwRI performs vibration problem diagnosis, monitoring systems and
surveys, resonance identification, flow-induced vibration, rotating
machinery diagnosis, installation and commissioning support, rotor
balancing, and third-party evaluation.
-
Turbomachinery Performance Diagnosis: Diagnosis of measurement
accuracy, performance measurements, power output, and heat rate.
Meter audits and flow meter calibrations. Heat rate improvement
studies, waste heat recovery analyses, and fluid mechanics and heat
transfer analyses.
-
Design Assurance: Rotor dynamics analysis (lateral, torsional, or
instability), pulsation control, FEA and CFD analyses, and
probabilistic evaluation. Design consultation and technical
representation. Optimization and system integration for specialty
applications of turbines and turbocompressors.
-
Computational Fluid Dynamics: We investigate and study a broad range
of problems such as penetration mechanics, computational
constitutive modeling, turbulent fluid flow, complex fluid flows,
large deformation material response, failure response, multiphase
flow, and fate and transport modeling.
-
Metering Research Facility (MRF): The MRF provides assistance with
flow meter design, development, and calibration; meter station
layout and optimization; field meter diagnostics and
troubleshooting; gas sampling methods; and personnel training.
-
Flow Measurement: Test gas flow rates up to approximately 7,000,000
standard cubic feet per hour can be provided at pressures ranging
from near atmospheric to 1,215 psig. Pipe and flow meter diameters
from 0.25 to 20 inches can be accommodated.
-
Fluid Machinery and Design Services: Capabilities include
simulation, analysis, and design of reciprocating and centrifugal
compressors, pumps, and their associated piping and valves. The
design facility emphasizes a concurrent engineering approach
consisting of a number of integrated elements.
-
Gas Turbine Technology: SwRI works with turbine users, suppliers,
and manufacturers of gas turbines to provide technical services,
expertise, and research facilities to design, construct, and operate
reliable and efficient turbines that meet market needs and respect
the environment.
