Case History: Vertical Pumps in Hazardous Areas Last Updated: 05/10/2017 |
A refinery in the Far East wanted Vibration Monitoring for thirteen (13) Vertical Pumps installed in a Class 1, Division 1 Hazardous Area. They also required access to the buffered dynamic signals for their portable analyzer in a safe location. They specified traditional API-670 monitoring with OK, Alert and Danger Relays, 4-20 mA output and local display for Operators in engineering units.
Solution: t was decided that three (3) IS rated Accelerometers would be mounted horizontally with one (1) at the motor upper bearing, one (1) at motor lower bearing and one (1) at pump upper bearing. IS Barriers would be used per accelerometer manufactures instructions. Space for a fourth channel was to be provided for future use. |
