Description
Technical field
The present invention relates to a kind of steam turbine technology field, particularly a kind of direct current direct-injection steam turbine.
Background technology
The high-efficiency blade complex contour of existing steam turbine, has high demands to quiet, dynamically balanced, otherwise can unbalance vibrate,
Can not normally use.Make manufacturing and designing of steam turbine more and more multifarious, manufacture difficulty is big, cost remains high.Existing vapour
Turbine, carries out energy conversion using high velocity air impact turbine blade, and the exhalation flow amount of entering relying between dynamic and static leaf grating changes
Obtain thrust, such result, under the conditions of leading to certain air velocity, the thrust of blade is related to rotating speed, there is optimum speed ratio.
During general optimum speed ratio, the rotation linear velocity of rotor is the 46%-48% of impact air-flow speed, when reaching maximum thrust, improves and turns
Fast thrust declines on the contrary, and when such as rotation linear velocity gentle flow velocity degree is consistent, thrust is zero.So it is greatly lowered existing steamer
The power conversion of machine, leads to the efficiency of existing steam turbine unsatisfactory, theoretically, such as calculates existing vapour with physics vector method
The power of turbine, computing formula is exactly: n=p*l*r/9550=m*r/9550, and the efficiency of existing steam turbine is exactly 25%, existing
Technology does not also have efficient steam turbine.
Content of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide a kind of structure is simple, energy conversion efficiency shows
Write the direct current direct-injection steam turbine higher than traditional steam turbine.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
Direct current direct-injection steam turbine, comprising: access the hollow axle of steam, be arranged at the rotary power assembly of hollow axle, direct connection
