Description

technical field [0001] The invention belongs to the field of industrialized production, and in particular relates to an on-site dynamic balance calculation and adjustment method of a rotary machine based on office software. Background technique [0002] The unbalance of rotating machinery is the most common fault in industrial production sites. The mass imbalance of the rotor system is the main cause of vibration faults. Engineering practice shows that implementing dynamic balance at the rated speed of rotating machinery on site is an effective way to solve unbalanced vibration faults. One, it is a method of vibration detection analysis and dynamic balance correction in the field working state or close state.

AI Technical Summary

Problems solved by technology

[0003] The problem of the prior art is that the current conventional on-site dynamic balance calculation and implementation methods of rotating machinery include drawing method or graphic method, vector calculation method, influence coefficient method, modal balance method, etc. The calculation and implementation of these methods are relatively complicated and labor-intensive. The amount is large, the construction period is long, and the accuracy is not high. Some companies invite professional teams to use special dynamic balancers to implement on-site dynamic balance for a fee, but the cost is relatively high, and ordinary companies rarely have the ability to independently implement on-site dynamic balance.

[0004] The problem of the prior art is that although a simple vibration analyzer does not have the function of implementing on-site dynamic balance, as long as it is used to measure the double-frequency amplitude and phase of the rotor vibration of a rotating machine, it can be completely autonomous, Fast and precise on-site balancing

The currently commonly used calculation methods are all fixed in professional dynamic balancing machines or balancer devices, or on professional computer software or mobile phone APP, which is very inconvenient to apply, especially the dynamic balance data that has been implemented in history cannot be saved and queried at any time. , cases and results, and does not have the online real-time data correction function, which brings a lot of inconvenience to the on-site implementation workers and greatly reduces the probability of successful on-site implementation
