What Is the API 670 Standard And How Does It Benefit Electronic Overspeed Detection Systems?
When a rotating machine experiences an overspeed event it means that it is likely to have exceeded its design limits, leading to potentially serious and costly damage to the machine, the plant buildings and infrastructure and even a life-threatening situation. The extent of the damage depends on two factors: how much the rotation exceeds design limits and for how long the event persists.
To prevent this situation from occurring, an overspeed detection system can provide early warning of an overspeed event so that instantaneous action is taken to shut down machinery quickly and safely.
What Is The API 670 Standard?
API 670 is an industry-standard that defines the minimum requirements for machine protection systems, covering all aspects of hardware, installation, testing, and documentation.
API 670 applies to a number of measurements, including electronic overspeed detection systems that comprise speed sensors, output relays, and power supplies to measure the rotation speed of the shaft and activate the relays if an overspeed situation is detected. The API 670 standard also applies to other aspects of machine protection, including vibration, axial shaft position, piston rod drop, and machine temperatures.
How API 670 Defines Electronic Overspeed Detection
API 670 relates exclusively to electronic overspeed detection systems, as mechanical systems are now generally obsolete. For overspeed detection systems to comply with API 670 standards, the following conditions must be met:
