Abstract

The invention discloses a turbine blade online evaluation system and a turbine blade damage early warning method, and belongs to the technical field of turbine equipment. A turbine blade online evaluation system comprises a blade monitoring data acquisition system, a blade monitoring data management module, a blade state online evaluation module and a display processing module. A turbine blade damage early warning method comprises the following steps that 1, a blade monitoring data acquisition system is installed at the working position of a turbine and is in signal connection with a blade monitoring data management module; the turbine blade is monitored on line through the blade monitoring data acquisition system, real-time fatigue risk estimation, crack risk estimation and crack identification are performed on the turbine blade after comprehensive analysis of various data, crew personnel are prompted in a visual mode, the influence of a complex environment in a turbine on a sensor is eliminated, the early warning accuracy of the turbine blade is greatly improved, the breakage accident of the turbine blade is avoided, and the use efficiency of the turbine is improved.

Description

technical field [0001] The invention relates to an online assessment system for turbine blades and a damage early warning method for turbine blades, belonging to the technical field of turbine equipment. Background technique [0002] The steam turbine is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and is sprayed onto the blades, so that the rotor equipped with blade rows rotates and works externally. The steam turbine is used in the power plant of the ship, and the turbine blade is the key part of the steam turbine. It withstands high temperature, high pressure, huge centrifugal force, steam force, steam excitation force, corrosion and vibration, and water droplets in the wet steam area under extremely harsh conditions. Due to the combined effect of erosion, the working environment of turbine blades is harsh, and after long-term use, cracks will occur on turbine blades, and blade ...
