SUCCESS STORIES

High Speed Electric Motor Vibrations

During the commissioning on the test bench of a high speed permanent magnet electric motor, severe vibrations were experienced

Results

A detailed lateral analysis, confirmed by a hammer test, showed that that the first critical speed was within the operating range
The rotor was redesigned and the shaft stiffened to avoid to be close to a resonance.

Old centrifugal compressor

OEM no longer available. User wanted to extend the operating life of this old unit by upgrading machine monitoring

Results

Design and implementation of mechanical modifications to house new sensors
Supply and installation of a new vibration monitoring cabinet, linked to the plant DCS

Short piston rings life

Forced maintenance every 3 months due to fast wearing of PTFE piston sealing elements

Results

high performance PEEK material suggested
scheduled temperature monitoring program

TEMA

"The CST team identified the root cause of a surge problem that had been plaguing us for months. Within four weeks we already had the solution implemented and the machine back in operation."
