Abstract

The invention discloses a deep peak shaving turbine blade erosion test system and a test method thereof. The test system comprises a turbine test device, a particle erosion system and a droplet erosion system, wherein the particle erosion system comprises a particle tank, and a vibrating device, a screening device, a weighing machine, a propelling device, a high-frequency electric heating furnace,a mixer and a particle ejector which are installed below the particle tank; particles in the particle tank enter the screening device after passing through the vibrating device, and the screened particles enter the propelling device through the weighing machine; the propelling device is used for pushing the particles into the high-frequency electric heating furnace, and the high-frequency electric heating furnace is used for heating the particles; and the heated particles enter the mixer, then enter the particle injector, and the particle injector sprays the particles into a test chamber forparticle erosion tests. The test system can be used for researching the influence of different experimental conditions on erosion of turbine blades, has the advantages of being multiple in functions,high in applicability and the like, and is particularly suitable for research on the aspect of deep peak shaving turbine vibration.

Description

technical field [0001] The invention belongs to the field of steam turbine blade erosion tests, and more particularly relates to a deep peak-shaving steam turbine blade erosion test system and a test method thereof. Background technique [0002] Steam turbine blades are the key components of steam turbines, which are subjected to high temperature, high pressure, centrifugal force, exciting force, and blade corrosion and water drop erosion during work. In this working environment, scales, defects, cracks and fractures occur in the blades, resulting in vibration problems, which seriously affect the safe operation of the steam turbine. [0003] With the increasing capacity of steam turbines in power stations in my country, the safety and reliability of blades are becoming more and more important. Fouling of the blades and erosion of solid particles will cause the unit to vibrate if it is mild, and cause the unit to shut down if it is serious. The problem of the blade and its ...
