Problems solved by technology
[0005] The existing mechanical online balance correction system (device) has a relatively complicated structure, adopts the end face liquid injection method, and the liquid injection port is small
As the speed increases, the injection time window becomes shorter and shorter, and accurate injection becomes difficult, resulting in the inability to balance at high speeds
In terms of balance quantity calculation, the existing balance technology performs balance calculation by measuring unidirectional vibration signals, which cannot accurately reflect the vibration state of the rotor and affect the balance effect

Description
technical field [0001] The invention belongs to the field of mechanical system rotor dynamic balance, and relates to an application of an online dynamic balance technology—a liquid injection type rotor online holographic dynamic balance system. The invention is based on the principle and technology of holographic dynamic balance, and corrects the vibration caused by the imbalance of the rotor by injecting liquid into the balance head. Background technique [0002] As a key and basic technology of rotary machinery, dynamic balancing technology has been closely watched and valued by industry and academia. A large number of statistical data show that the unbalance of the rotor is usually the main cause of the vibration of the rotary machine. Unbalance will cause the deflection and internal stress of the rotor, aggravate the vibration of the machine, accelerate the wear of parts such as bearings and shaft seals, reduce the working efficiency of the machine, and cause various ac...
