The utility model content
The purpose of this utility model is the defective that overcomes prior art, and a kind of packing assembly tool for steam turbine is provided, and it can make things convenient for the assembling of packing, realizes stable, reliably matching requirements to packing, has improved the manufacture level of the packing of steam turbine.
The technical scheme that realizes above-mentioned purpose is: a kind of packing assembly tool for steam turbine, for the T-slot that labyrinth strip, washer and stay is installed on the nozzle inner headed face, this packing assembly tool comprises caudal peduncle and is connected to the die that rushes on caudal peduncle top, described caudal peduncle is connected with pneumatic motor, wherein
The described end face central authorities that rush die offer a groove, and this groove is made of top straight trough, middle part cone tank and bottom straight trough,
The width of the width of described top straight trough and the medial segment of labyrinth strip is adaptive, and the height of a side of this top straight trough is greater than the height of another side, the width of the width of described bottom straight trough and the segmentum laterale of labyrinth strip is adaptive, and the height of described middle part cone tank is greater than the length of the middle conical section of labyrinth strip;
The width of one side end face of described groove and the width of washer is adaptive and greater than the width of opposite side end face, the width of this opposite side end face is less than the respective side notch of the T-slot on the nozzle distance to the side of the respective side of nozzle.
The above-mentioned packing assembly tool that is used for steam turbine, wherein, the width of a side end face of described groove and the width of opposite side end face are respectively an arc surface to be set in the described two sides that rush die form.
The above-mentioned packing assembly tool that is used for steam turbine, wherein, described caudal peduncle also is connected a hand grip portion with described the punching between the die.
Packing assembly tool for steam turbine of the present utility model, easy to use, stable operation, safe and reliable can realize accurately that the riveting of rushing of turbine steam seal is assembled, and reach turbine steam seal and rush the riveting installation requirement.
