One-sided dynamic balance correction

1. Vibration signal: The vibration signal can only be collected using the local sensor (using an external sensor can only be qualitative and not quantitative).

2. Rotating signal: Various modes are available: laser-photoelectric device in the machine, optional laser tachometer HY-441LP or other user-supplied rotation signals (the latter two are input by “external trigger input socket”). Note: During the whole test process, the pick-up points of the vibration signal and the rotation signal should remain unchanged, and there should be no movement, otherwise the accuracy of the test will be affected.

4. Dynamic balance phase angle error: ±1° (electric signal simulation).

5. Separate rate: 1°.

Way of working

1. Vibration signal acquisition and analysis system working mode: Compose a vibration signal acquisition and analysis system with the supporting PC software to manage and implement equipment condition monitoring. The software that is compatible with this machine is based on the Windows operating system. It integrates analysis and communication into one, based on an efficient and reliable database, with advanced management functions, which can easily generate inspection plans and monitor equipment status for enterprises. Work provides effective support. The software has a variety of practical analysis functions that provide a scientific basis for equipment troubleshooting and maintenance planning.

2. Independent working mode: As a measuring instrument for independent work, it can measure vibration, temperature, speed and dynamic balance for equipment inspection under unplanned management.
