The invention discloses an experimental device for closed dynamic cyclic salt fog corroding compressor blades, and belongs to the field of dynamic salt fog experiments. The device comprises a salt foggenerating device, an outlet flowmeter of the salt fog generating device, an arc guide plate, a compressor, a compressor motor, a compressor outlet multiprobe pressure flowmeter, a compressor air inlet, a compressor air outlet, a salt fog generating device inlet, a salt fog generating device outlet and a pipeline. Influence factors in the whole salt fog experimental process can independently change with different operating conditions of the compressor, and the reliability of an experimental test is high. In the whole experimental process, the salt fog is constantly recycled, the salt fog lossis reduced, and the salt fog utilization efficiency is improved. The pipeline adopts transparent pressureproof acrylic materials, the salt fog flow situations are easily observed, certain light conditions are provided to strengthen the salt fog experimental effect.
Description
technical field [0001] The invention belongs to the field of dynamic salt spray test, in particular to a closed dynamic cycle salt spray corrosion compressor blade test device. Background technique [0002] The high concentration of chloride salts in the air above sea level due to the evaporation of seawater caused by sunlight, this corrosive atmosphere is called the marine atmosphere. In the marine atmospheric environment, salt spray is extremely corrosive to metal structures. Ships and carrier-based aircraft have served in the marine environment for a long time. The compressor is the main component of the gas turbine. Its function is to increase the pressure of the air flowing through the blades of the compressor and provide compressed air that meets the requirements for the combustion chamber. The key parts such as compressor blades are eroded and corroded under high pressure, high speed and humid air, which increases the loss of the compressor and reduces its performanc...
