Abstract
The utility model discloses a kind of turbine bodies, with bearing housing, turbine rotor and high-pressure cylinder, high-pressure cylinder has tubular cylinder body and round cylinder cap, turbine rotor one end is extend into bearing housing, the other end passes through round cylinder cap and extend into the tubular cylinder body of high-pressure cylinder, end outer gland is housed close to the position of turbine rotor on round cylinder cap, it further include having the circular ring shape steam baffle being set on the outside of the turbine rotor, the radial dimension of circular ring shape steam baffle is greater than the radial dimension of the end outer gland, bolt hole is evenly equipped in the circular ring shape steam baffle circumferential direction, bolt hole is provided with installation bolt, circular ring shape steam baffle is packed on the round cylinder cap on the outside of the outer gland of the high-pressure cylinder end by installation bolt thereon.Turbine body using the above structure, by leaked out between turbine rotor and the end outer gland steam flow bearing housing when stopped and diffused away by radially outward side by the circular ring shape steam baffle, will not enter in bearing housing.
Description
Technical field
The utility model relates to a kind of turbine bodies.
Background technique
Turbine body in the prior art, has bearing housing, turbine rotor and high-pressure cylinder, and high-pressure cylinder has cylinder
Shape cylinder body and round cylinder cap, described turbine rotor one end is extend into bearing housing, the other end passes through round cylinder cap and extend into height
In the tubular cylinder body of air cylinder, end outer gland is housed close to the position of turbine rotor on round cylinder cap.
Above-mentioned turbine body in the prior art is led since there is larger gaps between end outer gland and rotor
Gland packing leakage is caused to enter inside bearing housing, steam is in bearing housing internal condensate Cheng Shui, to causing to become rusty inside oil pipe line and bearing housing
Erosion falls off, and causes moisture in oil and granularity exceeded, has seriously affected the operation of Turbo-generator Set, can cause to burn when serious
Watt etc. accidents generation.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of gland packing leakages to enter inside bearing housing, thus
Will not to caused inside oil pipe line and bearing housing corrosion obscission, and then can guarantee Turbo-generator Set operate normally vapour
Turbine ontology.
In order to solve the above technical problems, the turbine body of the utility model, has bearing housing, turbine rotor and high pressure
Cylinder, high-pressure cylinder have tubular cylinder body and round cylinder cap, and described turbine rotor one end is extend into bearing housing, the other end is worn
It crosses round cylinder cap to extend into the tubular cylinder body of high-pressure cylinder, close to the position of turbine rotor equipped with outside end on round cylinder cap
Packing further includes having the circular ring shape steam baffle being set on the outside of the turbine rotor, and the radial dimension of circular ring shape steam baffle is big
In being evenly equipped with bolt hole on the radial dimension of the end outer gland, the circular ring shape steam baffle circumferential direction, bolt hole is provided with installation
Bolt, circular ring shape steam baffle are packed in the round cylinder cap on the outside of the outer gland of the high-pressure cylinder end by installation bolt thereon
On.
As the improvement of the utility model, the circular ring shape steam baffle is made of two semicircle baffles.
Turbine body using the above structure, due to further including having the circular ring shape being set on the outside of the turbine rotor
Steam baffle, the radial dimension of circular ring shape steam baffle are greater than the radial dimension of the end outer gland, and the circular ring shape steam baffle is circumferential
On be evenly equipped with bolt hole, bolt hole is provided with installation bolt, and circular ring shape steam baffle is packed in described by installation bolt thereon
On round cylinder cap on the outside of the outer gland of high-pressure cylinder end, therefore by leaking out between turbine rotor and the end outer gland
It is stopped when steam flow bearing housing by the circular ring shape steam baffle and is diffused away by radially outward side, bearing will not be entered
In case, therefore and then it will not can guarantee Turbo-generator Set to corrosion obscission is caused inside oil pipe line and bearing housing
It operates normally.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of partial structural diagram of turbine body of the utility model.
Fig. 2 is the structural schematic diagram of circular ring shape steam baffle in a kind of turbine body of the utility model.
Specific embodiment
Referring to Fig. 1-Fig. 2, the turbine body of the utility model, there is bearing housing 10, turbine rotor 20 and high pressure vapour
Cylinder 30, high-pressure cylinder 30 have tubular cylinder body 31 and round cylinder cap 32, and described 20 one end of turbine rotor extend into bearing housing 10
The interior, other end passes through round cylinder cap 32 and extend into the tubular cylinder body 31 of high-pressure cylinder 30, close to steam turbine on round cylinder cap 32
The position of rotor 20 is equipped with end outer gland 40, further includes having the circular ring shape steam baffle for being set in 20 outside of turbine rotor
50, the radial dimension of circular ring shape steam baffle 50 is greater than the radial dimension of the end outer gland 40, the circular ring shape steam baffle 50 weeks
It is evenly equipped with bolt hole 51 upwards, bolt hole 51 is provided with installation bolt 52, and circular ring shape steam baffle 50 passes through installation bolt thereon
52 are packed on the round cylinder cap 32 in 40 outside of high-pressure cylinder end outer gland.The circular ring shape steam baffle 50 can be by
Two semicircle baffles 53,54 form.
