Description

Turbine vibration probe assembly and disassembly tools Technical Field The utility model belongs to the technical field of disassembly and assembly of safety monitoring measuring points of a steam turbine, relates to a turbine vibration probe dismounting tool. Background When large-scale turbo generator sets are all provided with a steam turbine safety monitoring system TSI, key parameter data such as vibration, expansion, displacement and the like in the operation of a steam turbine are monitored in real time. Along with the higher and higher requirements of safe and reliable operation of the generator set, the measuring point of the TSI of the safety monitoring system of the steam turbine must work stably and reliably to acquire and transmit real-time accurate data of the steam turbine for monitoring the state and protecting critical interruption. The bearing vibration measuring point is one of the most important measuring points in a steam turbine safety monitoring system, and the bearing vibration measuring point must be firmly installed and accurately measured. Each power generation enterprise is usually provided with a plurality of power generation units, all probes are required to be disassembled, inspected and checked during unit maintenance, and then are subjected to reflow debugging according to the standard after the inspection, in order to ensure that the probes are mounted to the standard voltage value in the debugging process, the vibration probe fixing nuts are required to be continuously adjusted, the disassembly and assembly times of the vibration probes are more frequent, and the workload is high.
