Abstract
Cavity cleaning pipe is obturaged the utility model discloses rotation before a kind of High Pressure Turbine Rotor, include the conduit of copper structure, one end open and the other end closing of the conduit, the openend of the conduit is provided with the nut for being connected with cleaning machine outlet pipe, hemispherical joint for withstanding on the cleaning machine outlet pipe mouth of pipe, the hemispherical joint is provided with the through hole connected with the catheter interior, the through hole of the hemispherical joint is docked with the cleaning machine outlet pipe mouth of pipe, position close to the catheter lock end is provided with some apopores, some apopores are evenly arranged in the annular side of the conduit.The utility model is that a kind of engine high pressure turbine rotor obturages cavity cleaning frock, High Pressure Turbine Rotor quickly can be obturaged into cavity and cleaned up under conditions of High Pressure Turbine Rotor is not decomposed when using.
Description
Technical field
The utility model belongs to the maintenance technology field of aero-engine, and in particular to rotated before a kind of High Pressure Turbine Rotor
Obturage cavity cleaning pipe.
Background technology
CFM56-5B and CFM56-7B engines are the aero-engines of CFMI global groups production, are widely used in Boeing
On aircraft and Airbus Aircraft.There is cooling stomata on the High Pressure Turbine Rotor blade of both engines, cooling air is logical from this
Cross, cool down engine blade.Dust present in air, can enter engine, cause High Pressure Turbine Rotor in use
Blade cooling air-hole blockage, so as to be the reduction of high-pressure turbine blade cooling effect, substantially increases the ablation risk of blade.
In maintenance process, the dust for having bulk deposition in cavity is obturaged in rotation before High Pressure Turbine Rotor.
Because the cavity that cavity is a closing is obturaged in rotation before High Pressure Turbine Rotor, cleaning machine can only carry out clear to appearance
Wash.If to obturage cavity to rotation before High Pressure Turbine Rotor to clean, need plateau turbine rotor cell cube point first
Solution, single-piece and turbine disk single-piece are obturaged in rotation before being then respectively washed.So it is singly that decomposition and refitting unit body running are accomplished by 4
Its time, the inspection work for increasing part in addition is also huge, and brings great damage parts risk.
Utility model content
The purpose of this utility model is that provides rotary seal before a kind of High Pressure Turbine Rotor to solve the above problems
Tight cavity cleaning pipe.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Cavity cleaning pipe is obturaged in rotation before a kind of High Pressure Turbine Rotor, includes the conduit of copper structure, the one of the conduit
End opening and the other end are closed, the openend of the conduit be provided with for be connected with cleaning machine outlet pipe nut, for pushing up
In the hemispherical joint of the cleaning machine outlet pipe mouth of pipe, the hemispherical joint is provided with connected with the catheter interior logical
Hole, the through hole of the hemispherical joint is docked with the cleaning machine outlet pipe mouth of pipe, and the position close to the catheter lock end is set
Some apopores are equipped with, some apopores are evenly arranged in the annular side of the conduit.
Preferably, the vertical range of the apopore and the catheter lock end face is 10~60mm.
Preferably, the conduit passes through the nut and passes through the hemispherical joint and the nut clamping, and described half
Globe joint is connected to one with the conduit.
Preferably, it is provided with rubber protecting jacket on the conduit.
The beneficial effects of the utility model are：
The utility model is that a kind of engine high pressure turbine rotor obturages cavity cleaning frock, can not decomposed when using
Under conditions of High Pressure Turbine Rotor, High Pressure Turbine Rotor is quickly obturaged into cavity and cleaned up.
Brief description of the drawings
Fig. 1 is that the cross section structure diagram that cavity cleans pipe is obturaged in rotation before High Pressure Turbine Rotor described in the utility model；
In figure：1- nuts, 2- conduits, 3- rubber protecting jackets, 4- hemispherical joints, 5- apopores.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model includes the conduit 2 of copper structure, the one end open and the other end of conduit 2 are closed,
The openend of conduit 2 be provided with for be connected with cleaning machine outlet pipe nut 1, for withstand on the cleaning machine outlet pipe mouth of pipe half
Globe joint 4, hemispherical joint 4 is provided with the through hole connected with the inside of conduit 2, and through hole and the cleaning machine of hemispherical joint 4 go out
The water pipe mouth of pipe is docked, and the position close to the blind end of conduit 2 is provided with some apopores 5, and some apopores 5 are evenly arranged in conduit
2 annular side.
The vertical range of apopore 5 and the Closed End of conduit 2 is 10~60mm.
Conduit 2 is through nut 1 and by hemispherical joint 4 and the clamping of nut 1, and hemispherical joint 4 is fixedly connected with conduit 2
It is integrated.The plane of hemispherical joint 4 is fitted in the medial surface of nut 1, in order to more preferable anti-leak, in actual fabrication
Rubber gasket can be increased between the plane and the medial surface of nut 1 of hemispherical joint 4.
Rubber protecting jacket 3 is provided with conduit 2, it can play a protective effect to conduit 2, prevent part of damage.
Operation principle of the present utility model is as follows：
One end of conduit 2 is blocked, to change the direction of current, current is rinsed with easy angle before High Pressure Turbine Rotor
Cavity is obturaged in rotation.The aperture of apopore 5 is relatively shorter than the internal diameter of conduit 2, can reduce water export sectional area, pressure of increasing export
Power, increases the scouring force of current.Hemispherical joint 4 makes conduit 2 and cleaning machine effluent pipe mouth good seal, does not cause Lou to press.Spiral shell
Cap 1 makes conduit 2 to be installed to fast and reliable on cleaning machine.
Conduit 2 is fixedly connected on the outlet pipe of cleaning machine with nut 1 when in use, and ensures hemispherical joint 4
Spherical center and cleaning machine outlet pipe mouth of pipe central alignment, the through hole of hemispherical joint 4 and the pipe of cleaning machine outlet pipe
Mouth connection.The part of conduit 2 for being provided with some apopores 5 is stretched into rotation before High Pressure Turbine Rotor to obturage in cavity, Ran Houtong
Water just can be rinsed to inside cavity.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
In the range of shield.
