It uses.
Turbine rotor is the core component of turbogenerator, and the turbine of the prior art is all using vane type turbine rotor
Energy important task is converted to undertake, vane type turbine rotor makees rotor, and this just unavoidably will appear some disadvantages.Such as it works
Gas-turbine unit, the steam turbine engine of high temperature and pressure, when constituting engine with vane type turbine rotor, Jiu Huiyu
It involves great expense to blade rotor, thermal efficiency of cycle is lower than 40% when converting energy, the labyrinth type that leak fluid can only be used big
Sealing, bearing bear the technical problems such as axial thrust is big.
To solve above-mentioned technical problem, a kind of method for improving turbine engine efficiency of the patent No. 201410415779.3 and
Its device makes significant improvement in existing turbogenerator technical foundation, with high temperature high voltage resistant, low cost, conversion energy dose-effect
The high screwed pipe rotor of rate replaces expensive vane type turbine that thermal energy is converted to mechanical work, and institute's waste air temperature is greatly reduced, and manages
Thermal efficiency of cycle can at least be improved 5% than the prior art on, while remain gas-turbine unit technological merit.
Gas-turbine unit is able to be applied to automotive field, it is necessary to solve its turbine involve great expense, high temperature resistant it is high
Pressure, volume are big, environmental protection, transition heat low efficiency, working medium flow is big, output torque is small, revolving speed is high, 1000 kilowatts easily of output power
Above, it is difficult to work in the key technical problems such as unsteady flow working condition.
