Description
Technical Field
The invention belongs to the field of on-site measurement and debugging of in-service equipment, and relates to a system and a method for on-site measurement and debugging of a rigid suspension device of a pressed element.
Background
The boiler top of a thermal power plant is generally provided with a plurality of pressure elements such as headers, tube banks, steam guide tubes and the like, and some pressure elements are all suspended by rigid suspension devices. Due to the reasons of design, installation, long-term operation and the like, abnormal conditions such as underload, overload, unloading and the like can occur to part of rigid hanging devices, and even the problems of breakage and failure of connecting parts and compression elements and the like can be caused, so that the safe operation of the unit is seriously influenced. When the hanging device has bearing deviation, the bearing uniformity and the bearing rationality of the hanging device need to be measured, evaluated and debugged so as to ensure the safety of each pressed element and each connecting part. At present, the measurement and evaluation of the bearing uniformity and the rationality of the rigid hanging device of the in-service pressed element generally adopt (1) touch sense inspection, namely, each hanging device of the same pressed element shakes by hand to judge whether the bearing capacity is too large or too small; (2) and (4) hammering audio frequency inspection, namely hammering each hanging device of the same pressed element, and judging whether the bearing capacity is too large or too small according to the audio frequency. These two measurement and evaluation methods are extremely crude. After the bearing uniformity and the rationality of the rigid suspension devices of the compression element are measured and evaluated by a touch feeling inspection and hammering audio inspection method, the bearing of each suspension device is debugged by a torque wrench conventionally. Because the in-service unit equipment has the problems of corrosion and the like, the bearing debugging precision is poor. In addition, because the load changes of other hanging devices cannot be monitored when the single group of rigid hanging devices are debugged, the safety risk during debugging can be increased. Therefore, a system and a method for measuring and debugging the rigid suspension device of the compression element, which have high measurement accuracy, a real-time monitoring function, capability of backtracking the historical load measurement and debugging data in the early stage, and suitability for field use, are needed.
