CoDiS Monitoring system benefits

• Shaft center line position and alignment
• Run out compensation
• Critical speed analysis
• Identification of bearing stiffness
• Vibrodinamics condition analysis of rotary machines
• Umbalance problem solving
• Online temperature measurement of rotor and stator

Critical speed and rearing stiffness identification based on measurements made by CoDiS

Solution – change in the construction of bearing resultin with higher bearing stiffness

Critical speed analysis

Added element that made the bearing stiffer

Shaft geometry analysis

Result was shaft position in three planes

RUN-DOWN

RUNN DOWN TIME LINE

RUNN DOWN AS A FUNCTION OF ROTARY SPEED
