Description
Technical field
The utility model relates to a kind of condensing turbines, belong to condensed steam type turbine equipment technical field.
Background technique
The working principle of condensing turbine be certain pressure, temperature steam enter after expansion work in steam turbine it is solidifying
Vapour device condenses into water, extracts out through condensate pump, is sent after heaters at different levels heating to oxygen-eliminating device, is finally sent to pot as water supply
Furnace.There are many factor that the influence condensing turbine thermal efficiency improves is main, as steam turbine installs factor, turbine rotor knot
Structure, control of operating parameter etc..
Currently, that there are types is old for existing steam turbine, performance far lags behind the advanced level of similar unit, in practical fortune
There is also many defects in row, influence the thermal efficiency and safe and stable operation of steam turbine.In addition, existing steam turbine is mentioned by transformation
The space of high generatine set heat efficiency is little, increases equipment investment, and turbine thermodynamic efficiency improves unobvious.Therefore, it is necessary to existing vapour
Turbine is directly replaced, steam turbine and corollary equipment need to remanufacture, especially steam turbine, generator, condenser etc.
Basis needs to redesign, and pouring construction, project amount is very big, and the transformation period at least needs four months, and take effect phase extension, and original
Turbine Engine Foundation cannot achieve recycling.
Utility model content
The utility model aim is to provide a kind of condensing turbine, can guarantee the thermal efficiency of steam turbine, reduce simultaneously
Equipment investment shortens the transformation period, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of condensing turbine, it is described comprising cylinder, rotor, stator blade, movable vane piece, packing, air intake and steam drain
Cylinder be upper and lower two cage connections at a closing steam chest, equipped on air intake and steam drain, the inside of cylinder is set cylinder
There is a rotor, the rotor is equipped with the movable vane piece of multiple parallel arrangements, fixes multiple parallel arrangements on the shell of cylinder
Stator blade, the stator blade arranged for interval in movable vane piece and cylinder baffle on the rotor, sets between rotor and the shell of cylinder
There is packing.
Movable vane piece on the rotor totally ten one, respectively the first grade blade, the second grade blade, third grade blade,
Four grade blades, level V blade ....
The distance between the fourth stage blade and level V blade are greater than the distance between other two adjacent blades.
Clearance sealing device of the packing between rotor and the shell of cylinder.
Stator blade on the cylinder baffle is fixed on the shell of cylinder by partition.
Using the utility model, cylinder receives high-speed flow by air intake and steam drain, and the kinetic energy of steam is converted into
Mechanical energy rotates rotor, and packing is the clearance sealing device between rotor and the shell of cylinder, can prevent steam leakage and
Air is leak into.
The beneficial effects of the utility model are: can use original Turbine Steam while guaranteeing turbine thermodynamic efficiency
Dismounting basis is omitted in cylinder installation foundation, need to redesign and the duration of pouring construction and investment, shortens at least three months
Steam turbine installation, transformation period.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: cylinder 1, rotor 2, stator blade 3, movable vane piece 4, packing 7, air intake 8, steam drain 9.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of condensing turbine, comprising cylinder 1, rotor 2, stator blade 3, movable vane piece 4, packing 7, into vapour
Mouthfuls 8 and steam drain 9, the cylinder 1 be upper and lower two cage connections at a closing steam chest, cylinder 1 is equipped with air intake 8 and arranges
On steam ports 9, the inside of cylinder 1 is equipped with a rotor 2, and the rotor 2 is equipped with the movable vane piece 4 of multiple parallel arrangements, cylinder 1
The stator blade 3 of multiple parallel arrangements is fixed on shell, between the stator blade 3 on 1 shell of the movable vane piece 4 on the rotor 2 and cylinder
Packing 7 is equipped between arrangement, rotor 2 and the shell of cylinder 1.
In the present embodiment, stator blade 3 is fixed on the shell of cylinder 1 by partition, and cylinder 1 is divided into several vapour
Room.
The length of rotor 2 is 4460mm, movable vane piece 4 totally ten one on rotor 2, respectively the first grade blade, the second level
Blade, third grade blade, fourth stage blade, level V blade ..., wherein between fourth stage blade and level V blade away from
From the distance between other two adjacent blades are greater than, i.e. steam chest between fourth stage blade and level V blade is greater than other two
Steam chest between a adjacent blades.
Cylinder 1 is mounted on by the basis of grouting fixation, and the movable vane piece 4 on rotor 2 receives the high speed of nozzle blade cascade injection
The kinetic energy of steam is converted into mechanical energy by air-flow, rotates rotor 2.Packing 7 is that the gap between rotor 2 and the shell of cylinder 1 is close
Seal apparatus can prevent steam leakage and air from leaking into.
