Vibration monitoring and protection of rotating machinery 16:
Steam turbine: Real-time monitoring of parameters such as shaft vibration, shaft displacement and rotational speed of the steam turbine can timely detect imbalance, misalignment, friction and other faults of the steam turbine during operation, so as to avoid damage to the equipment and interruption of production. For example, by monitoring the amplitude and frequency changes of shaft vibration, it is possible to determine whether the operating status of the turbine is normal, so that corresponding maintenance measures can be taken in time.
Compressor: During the running process of compressor, monitoring its vibration, displacement and other parameters can effectively prevent the compressor from shutting down due to failure and guarantee the continuity of production. For large centrifugal compressors, the Bentley 3500 module can accurately monitor the vibration of the compressor rotor, providing a strong guarantee for the stable operation of the equipment.
Fans: Whether it is a ventilator, blower or induced draft fan, its vibration status needs to be monitored. The Bentley 3500 module can collect the vibration signal of the fan in real time and issue an alarm in time according to the set alarm value to remind the staff to carry out maintenance and overhaul of the fan to extend the service life of the fan.
Water pump: It is used to monitor the shaft vibration, shaft displacement and other parameters of the water pump to prevent the pump from being damaged due to excessive vibration. In some occasions with high requirements for water supply stability, such as urban water supply systems, nuclear power plants, etc., the application of Bentley 3500 modules can ensure the normal operation of water pumps and guarantee the safety of water supply.
Gearbox: Gearbox is an important part of the mechanical transmission system, and its running status directly affects the performance of the whole equipment. Bentley 3500 module can monitor the gear box vibration, temperature and other parameters, timely detection of gear wear, tooth surface gluing and other faults, to avoid the expansion of equipment failure.
Motor: Monitoring the vibration, temperature, speed and other parameters of the motor can effectively prevent the motor from burning out due to failure. In some large motor-driven equipment, such as large cranes and shield machines, the application of the Bentley 3500 module can ensure the stable operation of the motor and guarantee the safe operation of the equipment.
Key-phase measurement and analysis: The key-phase module is used to detect the alignment of the key-phase markings on the shaft with the key-phase sensor, so as to determine the rotational phase and speed of the shaft.2 In the case of multiple pieces of equipment running in tandem, such as large production lines and generator sets, key-phase measurement can be used to achieve synchronized control and coordinated operation among the equipment. For example, in a turbine-generator set in a power plant, key-phase measurement can ensure that the rotational speeds of the turbine and generator are synchronized to ensure stable power output.
System Integration and Data Communication 3:
As a component of industrial automation systems: During the installation of new equipment or systems, the Bentley 3500 module can be used as a component to realize data exchange and control between different devices. It supports communication protocols such as Ethernet and RS232, enabling seamless connection with other automation devices to build an efficient industrial automation system.
Connection with PLC or DCS system: The monitored data can be transferred to PLC (Programmable Logic Controller) or DCS (Distributed Control System) to provide data support for the control and optimization of production processes. For example, in chemical production, the Bentley 3500 module transmits the operation data of rotating machinery to the DCS system, and operators can monitor and adjust the production process in real time based on this data to improve production efficiency and product quality6.
Special working condition monitoring:
Gas turbine combustion chamber pressure monitoring: specific modules in the 3500 system can be used to monitor the intermittent instability (“beeping”) of the pressure in the combustion chamber of the gas turbine, helping staff to detect abnormalities in the combustion chamber in time, and safeguarding the safe operation of the gas turbine4.
Monitoring of low-speed machines: For some low-speed machines, such as hydroelectric turbines / hydrogenerators in hydropower plants, etc., the relevant modules in the 3500 system provide suitable frequency response characteristics and special signal processing functions, which can accurately monitor the operating status of these equipment4.
