Abstract

The invention discloses a debugging and fixing device of turbine blade vibration on-line monitoring equipment, and relates to the technical field of turbines so as to solve the problem that existing sensors of monitoring a turbine blade is unlikely to adjust and fix. The debugging and fixing device comprises circumferential fixing plates, a vertical adjusting plate, a transverse pulling plate, twocircumferential swing plates and two axial adjusting plates, the transverse pulling plate is fixed on a frame body of the turbine blade vibration on-line monitoring equipment, the vertical adjustingplate is fixed on the transverse pulling plate through bolts and can adjust horizontally, each circumferential fixing plate is fixed on the vertical adjusting plate through bolts and can adjust up anddown, each circumferential swing plate is fixed on the corresponding circumferential fixing plate through bolts and can swing by a certain angle, and each circumferential adjusting plate is fixedly connected with the corresponding axial swing plate. According to the debugging and fixing device of the turbine blade vibration on-line monitoring equipment, the sensors conduct large-range adjusting in three directions and adapts to the blades of different lengths and the top forms of different shapes.

Description

technical field [0001] The invention belongs to the technical field of steam turbines, and in particular relates to a debugging and fixing device for on-line monitoring of vibration equipment of steam turbine blades. Background technique [0002] When the steam turbine is running, the blades are always in a vibrating state under the action of the steam force. When the unit load changes drastically or the long-term operating conditions deviate from the design conditions, the safety of the blades may be affected. If a certain blade of the steam turbine has a crack during operation, the blade vibration monitoring system can measure that this blade is indeed in a different operating state from other blades due to the crack, so that further increase of blade cracks can be avoided. If it breaks, it can actively shut down and replace the blades, which not only improves the safety of the unit operation, but also reduces the diameter loss of the power plant. Since the blade vibratio...
