Laboratory Test Services
Performance Testing
Single or multiple point performance testing. Performance
testing recording flow rate, head, input power , speed and temperature are
used to completely define the operation of pumps. Performance testing in
accordance to Hydraulic Institute Level A or B standards is available.
Net Positive Suction Head Required Testing
Single or multiple point NPSHR testing can be done
depending on the application. Multiple speed testing can also be done to
determine NPSHR curves for variable speed operation. Testing can be done using
the current Hydraulic Institute 3% head drop criteria or at the 1% head drop
preferred by some compani es.
Accelerated Endurance Testing
Often referred to as Mean Time Between Failure (MTBF) or
Life Testing. These tests are designed to predict the type and time before
failure for pumps and pump systems. Through the use of statistical techniques
and proprietary algorithms MechTronix is able to confidently predict the time
before failure for a population of rotating equipment. Test cycles can often
be compressed by a factor of 4 allowing us to accrue one year of test time in
a 3 month period.
Vibration Analysis
Complete spectral vibration analysis. Determination of
machine natural frequencies, and acceptance testing can be done using spectral
vibration analysis. Problems such as unbalance, faulty bearings, rotor/stator
contact, hydraulic problems, gear misalignment, etc can be diagnosed using
this technique. Using vibration analysis in conjunction with performance
testing allows the design engineer with a great deal of insight into the
operation of the product.
Radial and Axial Load Testing
Proprietary methods are used to determine actual
hydrodynamic loads on the pump. Loads can be collected as a time average
data or dynamically to determine spike loading on the bearings. The
dynamic loading combined with vibration data can often be useful in
failure analysis, or mean time between failure (MTBF) prediction.
Internal Temperature Rise
Fluid temperature rise through bearings, magnetic
drive, and canned motor sections.
Rotor Efficiency
Determination of the impeller efficiency alone. This
allows the designer to separate component efficiencies, determine the low
efficiency component, and work on it instead of guessing at pump problems
from the shape of the performance curve
Seal Chamber Performance
Temperature and pressure profiles, Seal Face
temperatures and pressures are used to completely profile the operating
conditions on the mechanical seal allowing for better prediction of the
performance and life of the seal.
Sound Level Testing
Basic testing can be done to determine the magnitude of
sound levels of the equipment. Advanced testing can include frequency
analysis to pinpoint causes of excessive noise.
Nozzle Loading
Acceptable pipe loading and hold down bolt reactions.
Advanced testing includes the use strain gages to determine stress levels in
the casings, mounting bolts and dial indicators to determine movement .
Dynamic Pressure Testing
Dynamic testing can be used to determine Hydro
dynamically induced blade stresses, pressure pulsations from rotary positive
displacement pumps, water hammer forces, etc.
