The mechanical braking system is the key equipment in the shutdown process of the hydroelectric generator set, and its operating state is directly related to the safety of the unit. It is difficult for traditional monitoring methods to grasp the displacement status of air brake brakes in real time, and there are safety risks. Online monitoring system for air brake displacementIt came into being, and through accurate monitoring and intelligent analysis of brake displacement, it provides a solid guarantee for the braking safety of the unit.
1. System overview: real-time monitoring, prevention before it happens
The online monitoring system of air brake displacement is an intelligent monitoring solution specially designed for hydroelectric generator sets. Through a high-precision laser displacement sensor, the system collects the displacement data of the air brake brake in real time, automatically judges the operating status of the equipment, and alarms immediately when an abnormality occurs, effectively preventing mechanical failures and safety accidents caused by abnormal displacement.
