Abstract
The utility model belongs to the technical field of steam turbine tools, and particularly relates to a nitrogenization rotor protection case. The utility model discloses a nitrogenization rotor protection case which comprises an upper shell body and a lower shell body. A sealing device is arranged on the connecting portion of the upper shell body and the lower shell body on the lower shell body. A rotor frame used to contain a rotor is arranged inside the lower shell body, locking mechanisms capable of fixing the rotor are arranged at two ends of the rotor frame inside the lower shell body, and an air inlet and an air outlet are arranged inside the lower shell body. The nitrogenization rotor protection case provides a stable inert gas environment, and can not only reduce the rotor temperature, but also prevent outside air from corroding the rotor, and therefore protects the rotor well and prolongs the service life of the rotor.
Description
Technical field
The utility model belongs to steam turbine apparatus technical field, relates in particular to a kind of nitrogen rotor protection case that fills.
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 the effect of steam turbine rotor just seems and extremely important because rotor is in and tells in the rotation process, can produce a large amount of heats in the process that rotor rotates, and rotor is in the air can cause larger infringement to rotor when high temperature.So that shorten the working life of whole rotor greatly.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of nitrogen rotor protection case that fills is provided, and its technological scheme is as follows:
A kind of nitrogen rotor protection case 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 place, two ends that is positioned at rotor rack in the described 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 that can screw locking mechanism 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 utility model provides fills nitrogen rotor protection case, in use, rotor is put on the rotor rack of lower shell body, then uses swing arm to screw locking mechanism, and rotor is fixed in the lower shell body.Then, upper shell is placed on the lower shell body, by seal arrangement so that seal between upper shell and the lower shell body, so that innerly form an airtight space.Then by inlet hole, be filled with nitrogen, nitrogen through air outlet hole out, forms the stable nitrogen environment of an inner space after entering confined space.When rotor rotates, 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, working life that can Extending Rotor.
Be provided with the swing arm that can screw locking mechanism in the lower shell body of the present utility model, can screw locking mechanism with swing arm very easily, need to before screwing, not go to find out swing arm in other toolboxes, cumbersome.This type of design is so that take and deposit very easy of swing arm, also unusual practicality.
Lower shell body outer surface of the present utility model bottom is provided with support, is because mostly the general nitrogen rotor protection case that fills is columnar, and support can be so that the whole nitrogen rotor protection case that fills can be more steady when maintenance or placement.
Upper shell outer surface of the present utility model top is provided with lifting hole(eyelet); because to fill nitrogen rotor protection case generally all be heavier; so upper shell and lower shell body also all are heavier; artificial generally all remove motionless, so just need to separate upper shell and lower shell body by machinery in assembling during with maintenance.Lifting hole(eyelet) then is in order to make things convenient for hanging of machinery to get.
The utility model provides a kind of stable inert gas environment, not only can reduce the temperature of rotor, and can stop ambient air to the corrosion of rotor, has well protected rotor, has improved the working life of rotor.

Embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of nitrogen rotor protection case 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 place, two ends that is positioned at rotor rack 4 in the described 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 that can screw locking mechanism 5 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 utility model provides fills nitrogen rotor protection case, in use, rotor is put on the rotor rack 4 of lower shell body 2, then uses swing arm 8 to screw locking mechanism 5, and rotor is fixed in the lower shell body 2.Then, upper shell 1 is placed on the lower shell body 2, by seal arrangement 3 so that sealing between upper shell 1 and the lower shell body 2, so that inner form an airtight space.Then by inlet hole 6, be filled with nitrogen, nitrogen through air outlet hole 7 out, forms the stable nitrogen environment of an inner space after entering confined space.When rotor rotates, 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, working life that can Extending Rotor.
