Description
Technical field
It the utility model is related to a kind of suspension apparatus, and in particular to steam turbine cylinder installation equipment.
Background technology
Steam turbine is the rotary power machinery that the energy conversion of steam is turned into mechanical work, also known as steam turbine.Steamer
Machine is mainly used as prime mover of generating, can also directly drive various pumps, blower fan, compressor and propeller for vessels etc., can be with
Meet production and heat supply needs in life using the steam discharge of steam turbine or intermediate extraction.Steam turbine enters the steam from boiler
After entering steam turbine, successively by the nozzle and movable vane of a series of loop configurations, the heat energy of steam is converted into turbine rotor rotation
The mechanical energy turned.Steam carries out energy conversion by different way in steam turbine, just constitutes the steamer of different operating principle
Machine.
Steam turbine generally HTHP and it is high-revolving under the conditions of work, be a kind of more accurate heavy-duty machinery, one
As must with boiler or other steam generators, generator or other by the compositions such as driving machinery and condenser, heater, pump into
Complete equipment, together cooperation work.
Steam turbine is mainly made up of two aspects of rotating part and stationary part.Rotor in rotating part include main shaft,
Impeller, movable vane piece and shaft coupling etc..Rotor is come out by alloy steel forging overall processing.
All rotors are all finished, and after all blades of fit on, are carried out full speed rotation experiment and moved with accurate
Balance.Rotor is broadly divided into rotor bushing, integral rotor, welded disc turbine rotor and combined rotor.
Rotor bushing：The parts such as impeller, axle envelope set, shaft coupling are all that hot jacket is on stepped main shaft after processing respectively.
Using interference fit between each part and main shaft, to prevent impeller etc. because centrifugal force and action of thermal difference cause loosening, and passed with key
Pass torque.The rotor of mesolow steam turbine and the low pressure rotor of high-pressure turbine are frequently with sleeve structure.Rotor bushing is in high temperature
Under, impeller easily loosens with main shaft.So should not be as the high pressure rotor of high-temperature steam turbine.
Integral rotor：The parts such as impeller, axle envelope set, shaft coupling and main shaft are to be cut to form by a monobloc forging part, no hot jacket part,
This solves the problems, such as that impeller easily loosens with axis connection under high temperature.High, the middle pressure that this rotor is usually used in large-size steam turbine turns
Son.It is compact-sized, to startup and variable working condition strong adaptability, it is suitable under high temperature and runs, rotor is rigidly good, but forging is big, processing
Technological requirement is high, and process-cycle length, Quality of Large Forgings is difficult to ensure that.
Welded disc turbine rotor：Low Pressure Steam Turbine quality is big, and the centrifugal force born is big, is existed using impeller endoporus during rotor bushing
Larger elastic deformation will occur during operation, thus need to design the larger assembling magnitude of interference, but this can cause very big assembling
Stress, according to integral rotor, quality is difficult to ensure that, so using setting down, welds the welded disc turbine rotor of combination.It mainly by
Several impellers are welded with end axle split.Welded disc turbine rotor light weight, forging is small, compact-sized, and bearing capacity is high, with size
Integral rotor that is identical, having centre bore is compared, and welded disc turbine rotor intensity is high, good, the light weight of rigidity, but high to welding performance requirement,
The application of this rotor is limited by welding procedure and the method for inspection and material category.
Combined rotor：Combined by monobloc forging structure sleeve structure, the advantages of having two kinds of rotors concurrently.
When rotor is arranged in cylinder body, the lifting rope in the rotating shaft of two ends of rotor on set on boatswain chair, Ran Houtong
The mobile boatswain chair of driving, and mobile and lifting boatswain chair are crossed, rotor is placed in the correct position of cylinder body.
In the installation of steam turbine, first stationary housing, then the rotor made is moved into steamer by driving and suspension apparatus
Correspondence position in machine cylinder body.
