Abstract

The invention discloses a surge detection method and device, and relates to the technical field of detection. The problems that in an existing artificial surge point judging process, the requirementsfor the professional level and quality of technicists are strict, and surge cannot be accurately recognized, so that safety risk is caused to a unit, and the production efficiency of a compressor is affected are solved. According to the main technical scheme, the method comprises the steps of obtaining surge parameters monitored in real time through a parameter interface, calculating the working state of a current working point according to the surge parameters, and starting an anti-surge valve control system; in the state that a surge line offset coefficient changes, adjusting the working state and the anti-surge valve opening in real time; judging whether or not the adjusted changing condition of the working state reaches preset surge point trigger conditions; if the preset surge point trigger conditions are reached, determining the working point of the current working state as a surge point, and sending a valve opening adjusting instruction to the anti-surge valve control system.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a surge detection method and device. Background technique [0002] Surge refers to the phenomenon that during the operation of the centrifugal compressor, when the load is lower than a certain value, the normal delivery of gas is destroyed, and the discharge of gas varies from time to time, in and out, and strong vibration occurs. Simple In other words, it is the flow pulsation phenomenon of the centrifugal compressor when the inlet flow is less than the surge flow. Since surge is an inherent phenomenon of the compressor, it is very harmful. The occurrence of surge often causes damage to important components such as the equipment impeller, main shaft, bearing, guide vane, etc., and sometimes even leads to the scrapping of the entire unit. [0003] At present, the current detection of the surge point is usually judged by human experience, that is, it is judged by experienced te...
