Description
Technical field
The utility model relates to a kind of power generating equipment, especially a kind of components of steam turbine.
Background technique
Steam turbine is the external combustion rotary machine that steam thermal energy can be converted into mechanical work, after entering steam turbine, successively through nozzle and the movable vane of a series of loop configurations, is the mechanical energy that turbine rotor rotates by the thermal energy of steam from the steam of boiler.Steam turbine works usually under High Temperature High Pressure and high-revolving condition, is a kind of comparatively accurate heavy machinery.
Cylinder is the shell of steam turbine, and its effect is separated the flow passage component of steam turbine and air, forms the steam chest closed, and ensures that steam completes the transfer process of energy in steam turbine inside.
Turbine high-pressure outer shell will carry very large weight, and simultaneously hp outer cylinder also will keep steam turbine operationally stable, so the effect of hp outer cylinder is very large.Hp outer cylinder volume is comparatively large, and maintenance is comparatively difficult, and traditional hp outer cylinder runs stable not, will produce production hidden danger, and the maintenance of high-pressure cylinder extremely bothers after there is crackle, and the high-pressure cylinder intensity after maintenance also can not as before.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of turbine high-pressure outer shell, solves prior art high pressure cylinder body life time short, the problems such as maintenance difficult.
Technological scheme
A kind of turbine high-pressure outer shell, described turbine high-pressure outer shell is a kind of combined type cylinder, comprise upper cylinder half and lower cylinder, described upper cylinder half and lower cylinder are stitched together and form columniform cylinder, described lower cylinder outer surface is fixed with multiple steel ingot, described lower cylinder internal surface is provided with fixing device, described fixing device is one piece of chute along lower cylinder axis, the surface that described lower cylinder and upper cylinder half contact with each other is up is provided with multiple cylindrical protrusions, upper cylinder half and lower cylinder contact surface are provided with multiple cylinder shape groove in relevant position, described upper cylinder half internal surface is provided with chute, described runner position is relative with lower cylinder internal chute.
The chute that described lower cylinder and upper cylinder half internal surface are fixed is a kind of T-shaped chute.
Steel ingot on described lower cylinder outer surface has four, three circular steel ingots, a square steel ingot.
Beneficial effect
Turbine high-pressure outer shell described in the utility model is combined by upper cylinder half and lower cylinder, and cylinder body adopts one-step casting shaping, solid durable.
Turbine high-pressure outer shell described in the utility model is provided with steel ingot, for cooling the thick large position of cylinder body platform when cylinder casting, is conducive to cylinder body consecutive solidification when casting.
Be provided with inner casing fixing device in turbine high-pressure outer shell described in the utility model, can be used in fixing various forms of high-pressure inner cylinder.
Accompanying drawing explanation
Fig. 1 is the worm's eye view of lower cylinder in turbine high-pressure outer shell described in the utility model.
Fig. 2 is turbine high-pressure outer shell plan view described in the utility model.
Wherein: cylinder under 1-, 2-upper cylinder half, 3-chute, 4-steel ingot, 5-cylindrical protrusions, 6-cylinder shape groove.
Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
The utility model relates to a kind of turbine high-pressure outer shell, described turbine high-pressure outer shell is a kind of combined type cylinder, comprise upper cylinder half 2 and lower cylinder 1, described upper cylinder half 2 is stitched together with lower cylinder 1 and forms columniform cylinder, described lower cylinder 2 outer surface is fixed with multiple steel ingot 4, described lower cylinder 1 internal surface is provided with fixing device, described fixing device is one piece of chute 3 along lower cylinder 1 axis, the surface that described lower cylinder 1 and upper cylinder half 2 contact with each other is up is provided with multiple cylindrical protrusions 5, upper cylinder half 2 and lower cylinder 1 contact surface are provided with multiple cylinder shape groove 6 in relevant position, institute's upper cylinder half of telling 2 internal surface is provided with chute, described runner position is relative with lower cylinder internal chute 3.
The high pressure cylinder body of steam turbine has individual layer high-pressure cylinder and double-deck high-pressure cylinder two kinds, steam turbine described in the utility model adopts double-deck high-pressure cylinder, the fixing device of hp outer cylinder inside is used to carry inner casing, inner chute 3 form is varied, T-shaped chute 3 makes simply, structural stability is a kind of more common sliding groove structure.
Being provided with multiple steel ingot 4 at high pressure cylinder body outer surface, for cooling the thick large position of cylinder body platform when cylinder casting, being conducive to cylinder body consecutive solidification when casting.
When assembling steam turbine, first lower cylinder 1 is placed in precalculated position, then inner casing is embedded outer cylinder interior, then assemble the parts such as bearing, rotating shaft, impeller, hp outer cylinder is the main carrier of miscellaneous part in a word, also be basis, working environment in high-pressure cylinder is High Temperature High Pressure, so propose very high requirement to the intensity of high-pressure cylinder, because high pressure cylinder body volume is larger, not easily change, so intensity and the life-span of hp outer cylinder will be ensured.
Turbine high-pressure outer shell described in the utility model is rational in infrastructure, easy to assembly, is applicable to high temperature and high pressure environment.
Every in sum have upper cylinder half 2 and combine with lower cylinder 1, and inside is provided with fixing device, and outside is provided with the cylinder block of steel ingot 4 all within protection domain of the present utility model.
