On-site Rotating Machinery Dynamic Balancing Tester

▲ In the dynamic balancing trial weight method, it is necessary to add a known trial weight to a known position on the measured surface, and pay attention to the changes in vibration amplitude and phase after adding the weight compared to the original vibration amplitude and phase. If the data changes are not obvious, the vibration reduction effect after subsequent calculation and processing will also be not obvious. If the amplitude change is not obvious, increase the trial weight. If the phase change is not obvious, reposition the trial weight.

▲ For the first balancing of a rotor, the trial weight method must be used. After obtaining the influence coefficient through the trial weight method, the influence coefficient method can be used for balancing similar types of rotors, which is simpler to operate.

▲ This instrument can be powered by AC 220V or by the built-in 12V battery. Generally, it is recommended to charge with AC 220V and power with the 12V battery, so that the internal noise is relatively lower. Please note that when the battery voltage drops below 10V, it should be charged promptly. Otherwise, the battery life will be affected.

▲ The magnetic base of the sensor has strong suction and can easily pinch fingers, so please be very careful.

Overview of On-site Dynamic Balancing Tester:

With the rapid development of modern industry, higher and higher requirements are put forward for the performance of rotating machinery. When the mass center of rotating equipment does not coincide with the rotation center due to various reasons, vibration will be generated due to centrifugal force. This vibration seriously affects the accuracy of equipment use and shortens the life of support bearings. To eliminate this vibration, dynamic balancing technology must be used.

The PHY series dynamic balancing measuring instrument targets the highest technology at home and abroad, adopting large-scale integrated circuits and microcontroller technology. This instrument is multifunctional, can be used as a tachometer, as a vibration tester, and especially has all the functions for measuring dynamic balancing.

This instrument is simple to operate, with human-machine dialogue, menu prompts, and measurement data can be locked and held at any time. With dual power supply from the built-in battery and mains, it is very convenient for on-site dynamic balancing testing of rotating machinery. It can also be used with a balancing machine, directly replacing the balancing machine's electrical box, for the renovation of old balancing machines.



Precautions:

▲ During continuous measurement, do not easily press the "Reset" key, otherwise all data of the key will be lost. If you have the influence coefficient at hand, you can re-enter it.

▲ Be sure to carefully make the photoelectric mark and observe the accuracy of the machine speed. This is an important guarantee for the instrument to carry out dynamic balancing testing.

▲ There are many reasons for large machine vibration. Only when the same-frequency amplitude accounts for a large component of the total amplitude can the dynamic balancing method reduce vibration. Otherwise, ideal results cannot be achieved.
