Description

A kind of hydraulic turbine generator gas-tight sealing system of rotaty
Technical field
The utility model relates to a kind of gas-tight sealing system of rotaty, especially relates to a kind of hydraulic turbine generator gas-tight sealing system of rotaty.
Background technique
The effect of the hydraulic turbine generator sealing in the generating machinery is that the gap of blockading between rotating part and the standing part leaks, and the quality of sealability directly influences the safe and stable operation of unit.
Traditional hydraulic generator thrust bearing adopts packing seal structure; The sealing structure is when generator operation, and mist of oil gets into generator inside easily, can produce oil leakage phenomenon when serious; Greatly reduce the insulating property of generator stator and rotor, influence the working life of generator.
The model utility content
To the actual demand of hydraulic turbine generator, overcome the shortcoming of generator thrust bearing conventional seals structure, the utility model provides a kind of hydraulic turbine generator gas-tight sealing system of rotaty.
A kind of hydraulic turbine generator gas-tight sealing system of rotaty, described gas-tight sealing system of rotaty comprise suction tude, Seal cage, oil extraction mist pipe, outlet pipe and condenser; Described Seal cage comprises air-inlet cavity and exhaust cavity, and air-inlet cavity is connected to suction tude, and exhaust cavity is connected to outlet pipe, and suction tude is provided with stop valve, and exhaust cavity links to each other with condenser through outlet pipe, and oil extraction mist pipe links to each other with condenser.
Preferably, said oil extraction mist pipe is formed by connecting through insulating joint the more piece pipeline.
Preferably, said suction tude is formed by connecting through insulating joint the more piece pipeline.
Preferably, said outlet pipe is formed by connecting through insulating joint the more piece pipeline.
Preferably, described Seal cage adopts the copper bar sealing.
The utility model manufacturing process is simple, cost is low, installation and maintenance are convenient, not only simply but also practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the partial enlarged drawing of I structure among the utility model Fig. 1.
Fig. 3 is the partial enlarged drawing of II structure among the utility model Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but the protection domain of the utility model is not limited to this.
With reference to Fig. 1 ~ 3, a kind of hydraulic turbine generator gas-tight sealing system of rotaty comprises suction tude 1, Seal cage 7, oil extraction mist pipe 3, outlet pipe 5 and condenser 6; Described Seal cage 7 comprises air-inlet cavity 9 and exhaust cavity 10, and air-inlet cavity 9 is connected to suction tude 1, and suction tude 1 is formed by connecting through insulating joint 4 on 6 pipe joint roads; Exhaust cavity 10 is connected to outlet pipe 5, and outlet pipe 5 is formed by connecting through insulating joint 4 on 6 pipe joint roads.
Suction tude 1 is provided with stop valve 2, can regulate suction pressure.Exhaust cavity 10 links to each other with condenser 6 through outlet pipe 5, and oil extraction mist pipe 3 links to each other with condenser 6, and oil extraction mist pipe 3 is formed by connecting through insulating joint 4 on 5 pipe joint roads, and mist of oil is caused condenser.Seal cage 7 adopts the copper bar sealing, and copper strips 8 closely contacts with electric machine main shaft.
This system introduces Seal cage 7 by suction tude 1 with near the high-pressure air the rotor fan, and Seal cage 7 has two, and one is air-inlet cavity 9; One is exhaust cavity 10, and air-inlet cavity 9 internal air pressures are higher than exhaust cavity 10 internal air pressures, and air constantly gets in the exhaust cavity 10 in the air-inlet cavity 9; Exhaust cavity 10 is connected to outlet pipe 5, and outlet pipe 5 links to each other with condenser 6, and the air in the exhaust cavity 10 is caused condenser 6; Oil extraction mist pipe 3 links to each other with condenser 6; Mist of oil is caused condenser 6, make mist of oil can not pass two Seal cages, reach the effect of sealing.
