The Valve and Case Expansion Monitor is meticulously crafted for high reliability, specifically targeting a plant’s most critical rotating machinery. This 1-slot monitor seamlessly integrates with other AMS 6500 monitors, forming a comprehensive API 670 machinery protection monitor.
Applications for this monitor span across various industries, including steam, gas, compressors, and hydro turbomachinery.
The Valve and Case Expansion Monitor primarily serves to:
Case expansion monitoring involves the use of two inductive displacement sensors (LVDTs), typically mounted axially and parallel to the shaft on each side of the turbine case. Unlike non-contact sensors like eddy current sensors, inductive sensors make physical contact.
This monitoring is especially critical during startup, as it allows both sides of the turbine case to be monitored for proper expansion rates. Failure to do so can result in the turbine “crabbing,” where the case bends, potentially leading to rotor-case collisions.
The AMS 6500 Machinery Health Monitor seamlessly integrates into PlantWeb®, providing operations with integrated machinery health information in conjunction with the Ovation® and DeltaV™ process control systems. The AMS software equips maintenance personnel with advanced predictive and performance diagnostic tools, allowing them to confidently and accurately identify early signs of machine malfunctions.
