Unit pipeline protection method and system and equipment

Abstract

The invention discloses a unit pipeline protection method and system and equipment. The system comprises a strain detection module, a master controller and a data center; the strain detection module is used for detecting strain parameters of a unit, and sending the strain parameters to the master controller, the master controller is used for determining whether the strain parameters exceed the corresponding preset failure threshold value or not and used for controlling to shield the failure frequency point, the data center is used for obtaining the unit current work parameters after the mastercontroller determines that the strain parameters exceed the corresponding preset failure threshold value, according to the work parameters and the strain parameters, whether the shielding operation is executed or not is determined, and if the shielding operation is executed, the main controller is triggered to control shielding of the failure frequency point. Through the method and system, in theunit actual running process, the accuracy of shielding of the failure frequency point can be improved, pipeline breaking is avoided, and the aims of protecting the unit and enabling the unit to reliably run are achieved.

Description

technical field [0001] The present invention relates to the field of generating sets, in particular to a method, system and equipment for protecting pipelines of generating sets. Background technique [0002] At present, with the increasingly powerful functions of central air-conditioning, the pipelines of its outdoor units are also becoming more and more complicated. In the process of product development, the problem of excessive stress and strain of the pipeline can usually be solved by adjusting the pipeline structure, adding flexible fixation or shielding the frequency point of the compressor. However, with the mass production of products, there will inevitably be problems with product consistency. Specifically, for example, the frequency shielding point of a certain batch of compressors is not the resonance point of the pipeline. During the operation of a certain batch of compressors, the resonance point of the pipeline shifts. There are problems of resonance or exces...
