Abstract
The invention belongs to the technical field of appliances of turbines, and particularly relates to a nitrogen charging rotor protecting box. The nitrogen charging rotor protecting box comprises an upper shell and a lower shell, a sealing device is arranged on the lower shell and positioned at a joint of the upper shell and the lower shell, a rotor rack capable of holding a rotor is arranged in the lower shell, locking mechanisms capable of fixing the rotor are arranged in the lower shell and positioned at two ends of the rotor rack, and a gas inlet hole and a gas outlet hole are arranged in the lower shell. A stable inert gas environment is provided, the temperature of the rotor can be reduced, furthermore, corrosion to the rotor due to external air can be stopped, the rotor is protected well, and the service life of the rotor is prolonged.
Description
Technical field
The invention belongs to steam turbine apparatus technical field, relate in particular to a kind of nitrogen rotor guard box that fills.
Background technique
Steam turbine is the rotary power machinery that the transformation of energy of steam is become mechanical work, claims steam turbine again.Main prime mover as generating usefulness also can directly drive various pumps, blower fan, compressor and propeller for vessels etc.Can also utilize the steam discharge or the intermediate extraction of steam turbine to satisfy production and heat supply needs in life.And the effect of steam turbine rotor just seems and extremely important because rotor is in and tells in the rotation process, in the process of rotor rotation, can produce great amount of heat, and rotor is in the air can cause bigger infringement to rotor when high temperature.Make shorten greatly the working life of whole rotor.
Summary of the invention
The objective of the invention is to solve above-described technical problem, a kind of nitrogen rotor guard box that fills is provided, its technological scheme is following:
A kind of nitrogen rotor guard box that fills; Comprise upper shell and lower shell body; The jointing place that is positioned at upper shell and lower shell body on the described lower shell body is provided with seal arrangement; Be provided with the rotor rack that to place rotor in the described lower shell body, but the two ends place that is positioned at rotor rack in the said lower shell body is provided with the locking mechanism of fixed rotor, is provided with inlet hole and air outlet hole in the described lower shell body.
Optimal way is to be provided with the swing arm of the locking mechanism of can screwing in the described lower shell body.
Optimal way is that described lower shell body outer surface bottom is provided with support.
Optimal way is that described upper shell outer surface top is provided with lifting hole(eyelet).
The nitrogen rotor guard box that fills provided by the invention in use, is put into rotor on the rotor rack of lower shell body, uses the swing arm locking mechanism of screwing then, is fixed on rotor in the lower shell body.Then, be placed on upper shell on the lower shell body, make through seal arrangement to seal between upper shell and the lower shell body, make inside form an airtight space.Through inlet hole, charge into nitrogen then, nitrogen is coming out through air outlet hole after getting into confined space, forms the stable nitrogen environment of an inner space.When rotor rotation, owing to be nitrogen environment in the inner space, and nitrogen is stable inert gas; Can reduce the temperature of rotor; Also can completely cut off rotor because high temperature and changing with corrosion that air produces plays the effect of protection rotor, can prolong the working life of rotor.
Be provided with the swing arm of the locking mechanism of can screwing in the lower shell body of the present invention, can use the swing arm locking mechanism of screwing very easily, need before screwing, not go to find out swing arm in other toolboxes, cumbersome.This type of design makes takes and deposits very easy of swing arm, also unusual practicality.
Lower shell body outer surface of the present invention bottom is provided with support, is because mostly the general nitrogen rotor guard box that fills is columnar, and support can be so that the whole nitrogen rotor guard box that fills can be more steady when maintenance or placement.
Upper shell outer surface of the present invention top is provided with lifting hole(eyelet); Be because to fill nitrogen rotor guard box generally all be heavier; So upper shell and lower shell body also all are heavier; Manual work is generally all removed motionless, so when assembling with maintenance, just need separate upper shell and lower shell body through machinery.Lifting hole(eyelet) then is that hanging of machinery got for ease.
The invention provides a kind of stable inert gas environment, not only can reduce the temperature of rotor, and can stop the corrosion of ambient air, well protected rotor, improved the working life of rotor rotor.

Embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of nitrogen rotor guard box that fills; Comprise upper shell 1 and lower shell body 2; The jointing place that is positioned at upper shell 1 and lower shell body 2 on the described lower shell body 2 is provided with seal arrangement 3; Be provided with the rotor rack 4 that to place rotor in the described lower shell body 2, but the two ends place that is positioned at rotor rack 4 in the said lower shell body 2 is provided with the locking mechanism 5 of fixed rotor, is provided with inlet hole 6 and air outlet hole 7 in the described lower shell body 2.
Optimal way is to be provided with the swing arm 8 of the locking mechanism 5 of can screwing in the described lower shell body 2.
Optimal way is that described lower shell body 2 outer surfaces bottom is provided with support 9.
Optimal way is that described upper shell 1 outer surface top is provided with lifting hole(eyelet) 10.
The nitrogen rotor guard box that fills provided by the invention in use, is put into rotor on the rotor rack 4 of lower shell body 2, uses swing arm 8 locking mechanism 5 of screwing then, is fixed on rotor in the lower shell body 2.Then, be placed on upper shell 1 on the lower shell body 2, make through seal arrangement 3 sealing between upper shell 1 and the lower shell body 2 to make inside form an airtight space.Through inlet hole 6, charge into nitrogen then, nitrogen is coming out through air outlet hole 7 after getting into confined space, forms the stable nitrogen environment of an inner space.When rotor rotation, owing to be nitrogen environment in the inner space, and nitrogen is stable inert gas; Can reduce the temperature of rotor; Also can completely cut off rotor because high temperature and changing with corrosion that air produces plays the effect of protection rotor, can prolong the working life of rotor.
Claims (4)
1. one kind is filled nitrogen rotor guard box; Comprise upper shell and lower shell body; It is characterized in that the jointing place that is positioned at upper shell and lower shell body on the described lower shell body is provided with seal arrangement, be provided with the rotor rack that to place rotor in the described lower shell body; But the place, two ends that is positioned at rotor rack in the said lower shell body is provided with the locking mechanism of fixed rotor, is provided with inlet hole and air outlet hole in the described lower shell body.
