Typically, the radial deflection of a pump shaft and impeller is determined by using either a dial indicator or a proximity probe.
To carry out the measurement, the dial indicator or proximity probe is affixed to a stationary surface close to the pump shaft and impeller. Then, it is positioned to come into contact with the rotating shaft or impeller.
As the shaft and impeller rotate, any radial deflection or movement will cause a corresponding displacement of the dial indicator or proximity probe. This displacement is subsequently assessed and recorded using the appropriate unit of measurement, such as inches or millimeters.
This measurement serves the purpose of identifying any misalignment or excessive radial deflection within the pump system. Such issues can lead to heightened vibration, reduced performance, and even potential harm to the pump components. By consistently monitoring and measuring the radial deflection, maintenance personnel can take prompt corrective measures to ensure the proper alignment and operation of the pump shaft and impeller.
The radial deflection of a pump shaft and impeller is typically measured using a dial indicator or a proximity probe.
To measure the radial deflection, the dial indicator or proximity probe is mounted on a stationary surface near the pump shaft and impeller. The indicator or probe is then positioned to make contact with the rotating shaft or impeller.
As the shaft and impeller rotate, any radial deflection or movement will cause the dial indicator or proximity probe to move accordingly. The movement is then measured and recorded using the appropriate measuring unit (e.g., inches, millimeters).
This measurement helps identify any misalignment or excessive radial deflection in the pump system, which can lead to increased vibration, reduced performance, and potential damage to the pump components. By regularly monitoring and measuring the radial deflection, maintenance personnel can take necessary corrective actions to ensure proper alignment and functioning of the pump shaft and impeller.
The radial deflection of a pump shaft and impeller is typically measured using proximity probes or displacement sensors. These devices are installed near the shaft and impeller and can accurately detect any movement or deflection. The measurements are usually taken at specific points along the shaft and impeller to assess their performance and ensure they are within acceptable limits.
