Abstract
The utility model belongs to the technical field of the turbine appliances, and particularly relates to a blade. The blade comprises an arc-shaped main body, wherein a spile is installed on one end of the arc-shaped main body, a chamfer is positioned on the front end of the spile, and a clamp board is installed on the other end of the arc-shaped main body. The length of the clamp board is shorter than the length of the spile. The blade is simple in structure and convenient to use; moreover, the blade is enabled to provide larger and more motive power, and thus improves the efficiency of the turbine, and further enables movement of the whole shroud band to be more stable.
Description
Technical field
The utility model belongs to steam turbine apparatus technical field, relates in particular to a kind of blade.
Background technique
Steam turbine is the rotary power machinery that the transformation of energy of steam is become mechanical work, claims again steam turbine.Main prime mover as generating usefulness also can directly drive various pumps, blower fan, compressor and propeller for vessels etc.Can also utilize steam discharge or the intermediate extraction of steam turbine to satisfy production and heat supply needs in life.And in whole steam turbine, the Main Function of blade is the then rotor driven rotation of impact of bearing vapor stream.At present, the blade of use all is board-type generally, so lifting surface area is less, the kinetic energy of generation is just less, thereby so that the power of whole steam turbine is lower.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of blade is provided, and its technological scheme is as follows:
A kind of blade, described this leaf packet bracket main body, an end of described arc main body is provided with plate, and the front end of described plate is provided with chamfering, and the other end of described arc main body is provided with clamp, and the length of described clamp is less than the length of plate.
The blade that the utility model provides comprises the arc main body, so that main body has certain radian shape, can obtain larger lifting surface area, can afford larger gas shock power, thereby produces larger Driving force.
The utility model is provided with plate at an end of arc main body, and the front end of described plate is provided with chamfering, and the other end of arc main body is provided with clamp, and the length of clamp is less than the length of plate.So that can better being inserted in the shroud, goes in blade, simultaneously also so that blade can be certain oblique angle with shroud plugs.
The utility model is simple in structure, and is easy to use, can provide larger, more power to steam turbine, so that the efficiengy-increasing of steam turbine, simultaneously so that the running of whole shroud is also more stable.
