Surface-modified nuclear power plant voltage stabilizer sprayer rotary water core

Abstract

The invention provides a surface-modified nuclear power plant voltage stabilizer sprayer rotary water core. The surface-modified nuclear power plant voltage stabilizer sprayer rotary water core comprises a rotary water core body which is cylindrical, and rotary water flow separation plates uniformly distributed in the peripheral direction of the rotary water core body and comprising at least two spiral blades, wherein the adjacent spiral blades surround a spiral groove runner; and the surface-modified nuclear power plant voltage stabilizer sprayer rotary water core is configured for surface modification. The surface nonmetal ion permeation treatment is performed on the surface-modified nuclear power plant voltage stabilizer sprayer rotary water core after manufacturing by stainless steel,so that the center part is excellent in toughness, the surface is excellent in wear resistance, corrosion resistance and fatigue resistance, and the life and the operation reliability of a sprayer canbe effectively improved; and the surface modification technology for improving wear resistance, corrosion resistance and fatigue resistance of the rotary water core is simple, high in production efficiency and low in manufacturing cost.

Description

technical field [0001] The invention relates to a surface-modified nuclear power plant voltage stabilizer sprayer water spinner, in particular to a nuclear power plant pressurizer sprayer water spinner whose surface has been infiltrated with non-metallic ions. Background technique [0002] The sprayer is an important part of the pressurizer of the pressurized water reactor nuclear power plant. It plays an important role in the pressure control. Its main function is to atomize the supercooled water into a large number of droplets distributed according to a certain size. Heat exchange with the saturated steam inside the pressurizer, so that the saturated steam condenses and flows into the liquid water in the pressurizer, thereby reducing the system pressure and ensuring the safe operation of the nuclear power plant. The spray performance of the sprayer, such as spray angle, particle size, and uniformity of fog volume distribution, directly affects the volume design of the pres...
