Abstract

The invention provides a helium fan which comprises a spindle left supporting structure, a spindle right supporting structure, a spindle and a tank structure, wherein the tank structure can be cooled.A gas cavity is formed in the spindle left supporting structure, fan blades are arranged in the gas cavity and fixedly connected with the spindle, a helium inlet is formed in one end of the gas cavity, a helium outlet is formed in the other end of the gas cavity, the spindle is arranged in the tank structure, the spindle left supporting structure is arranged at the end of the tank structure, thespindle right supporting structure is arranged at the right end of the tank structure, the spindle is rotatably connected with the spindle right supporting structure, a motor is arranged in the tank structure and connected with the spindle, and the spindle is rotatably connected with the tank structure through a gas static pressure bearing structure. The helium fan solves the problems that a current fan is complicated in lubricating structure, high in fault rate and difficulty to seal, a sealing agent is easily melted and blended into a helium cooling loop and the like.

Description

technical field [0001] The invention belongs to the technical field of nuclear equipment, in particular to a helium blower. Background technique [0002] High-temperature helium-cooled nuclear reactors (hereinafter referred to as high-temperature gas-cooled reactors) have the advantages of high thermal efficiency (40%-41%), deep burnup (up to 20MWd / t uranium), and high conversion ratio (0.7-0.8). As a coolant, helium has good chemical stability, good heat transfer performance, and low induced radioactivity, and can safely take out residual heat after shutdown, with good safety performance. In order to maintain the pressure of the helium cooling cycle, the helium fan is one of the key components. The function of the helium fan is to provide the required pressure increase for the helium cooling circuit, so that the helium can overcome the pipeline and The pressure drop of the main force of each equipment flows in the circuit according to the rated speed, so that the helium ca...
