A6210 9199-00003 - Vibration Monitoring Module

Description

The A6210 monitor operates in 3 distinct modes: thrust position, differentialexpansion, or rod position. The Thrust Position mode accurately monitors thrust position and reliably providesmachinery protection by comparing the measured axial shaft position against alarmset-points – driving alarms and relay outputs. Shaft thrust monitoring is one of the most critical measurements on turbomachinery.Sudden and small axial movements should be detected in 40 msecs or less to minimizeor avoid rotor to case contact. Redundant sensors and voting logic are recommended.Thrust bearing temperature measurement is highly recommended as a complement tothrust position monitoring. Shaft thrust monitoring consists of one to three displacement sensors mounted in theaxial direction parallel to the shaft at the shaft-end or thrust collar. The displacementsensor is a non-contact sensor that measures shaft position.

For extremely critical safety applications, the A6250 monitor provides triple-redundantthrust protection built on the SIL 3-rated overspeed system platform. The A6210 monitor can also be configured for differential expansion measurements.As both the case and rotor grow due to changes in thermal conditions at turbinestart-up, differential expansion delivers a measure of the relative difference betweenmounted displacement sensors on the case and the sensor target on the shaft. If thecase and shaft grow at approximately the same rate, then the differential expansionremains close to the desired value of zero. The differential expansion measurementmode supports tandem/complementary or cone/ ramp modes. Finally, the A6210 monitor can be configured for average rod drop mode – used tomonitor rider band wear in reciprocating compressors. Over time, rider bands wearin horizontal reciprocating compressors due to the force of gravity acting on thehorizontally-oriented piston in the compressor cylinder. If the rider band wears beyondspec, the piston can contact the cylinder wall and cause incremental machine damageand possible failure.

By mounting at least one displacement probe to measure the piston rod position, youwill receive notification when the piston drops – an indication of rider band wear. Youcan then set shutdown protection thresholds for automatic trip. The average rod dropparameter can be factored to represent the actual rider band wear, or with no factorapplied, rod drop will represent the actual movement of the piston rod. The AMS 6500 includes easy integration to the DeltaV and Ovation process automationsystems, including preconfigured DeltaV Graphic Dynamos and Ovation GraphicMacros to speed operator graphic development. AMS software provides maintenancepersonnel advanced predictive and performance diagnostic tools to confidently andaccurately determine machine malfunctions early.
