Case Story: Boiler feed pump monitoring in Croatia

We designed a boiler feed pump vibration monitoring solution for a combined-cycle cogeneration unit (CCPP) in Croatia.

PCH 1420 vibration monitor with buffered outputs for easy raw data access

Permanently mounted sensors
Continuous monitoring in real time
Data visualisations and trending
Remote access to data
IoT and Modbus TCP compatible

The problem

The client wanted a vibration monitoring solution to protect two boiler feed pumps in a combined-cycle cogeneration unit (CCPP). By monitoring the vibration frequency of the pumps and their electrical motors, the client gets early warning of emerging faults or impending failure and can take appropriate preventive action.

The solution

We supplied a 16-channel monitoring solution as the client requested sensors in the X and Y positions on both pumps and motor bearings, amounting to a total of 8 sensors per pump.

Each pump is protected by two PCH 1420 Vibration Monitors with buffered outputs and BNCs, which allows vibration specialists to access the raw vibration data with handheld equipment. The PCH system delivers 4-20 mA signals to the DCS analogue card for trending and the relay outputs are connected to the DCS’s binary inputs for trip.

The PCH EtherBridge communication module was added to future-proof the solution for an expansion to IoT or Modbus TCP.
