Abstract

The invention discloses a heap helium turbine mechanism, and relates to a sealing device. The heap helium turbine mechanism solves the problems that an existing turbine is applied to a nuclear reactorso that an overall turbine case can form a whole, and disassembling and assembling are inconvenient; and an overall turbine stator structure is too long, a turbine guide device has the leakage loss,and the output power and the thermal efficiency of the turbine are reduced. The heap helium turbine mechanism includes a turbo stator structure (A) for a helium turbine and a turbo rotor (B) for the helium turbine. The turbine rotor (B) for the helium turbine is installed in the turbo stator structure (A) for the helium turbine, a first-stage separating plate pressure ring sealing device (C) is further included, and first-stage guide devices between the turbo stator structure (A) for the helium turbine and the turbo rotor (B) for the helium turbine are connected through the first-stage separating plate pressure ring sealing device (C). The heap helium turbine mechanism is used in the energy power industry.

Description

technical field [0001] The invention relates to a turbine overall mechanism, in particular to a stack helium turbine mechanism, which improves the characteristic matching between components of a gas turbine and improves the performance of the gas turbine, and belongs to the energy and power industry. Background technique [0002] Due to the small overall size of the helium gas turbine unit, high speed, high requirements on sealing, complex temperature field, complex deformation under high temperature and high speed, etc., it brings great difficulty to the structural design. The existing turbine stator structure is not suitable for the work of the helium turbine. The existing turbine is applied to the nuclear reactor and the entire turbine case is integrated, which is not easy to disassemble; and the overall length of the turbine stator structure makes the helium in the nuclear reactor The initial temperature of the gas entering the turbine and acting on the moving blades is ...
