Abstract

The invention discloses a sealing ring cutting device and a cutting method thereof, and relates to the technical field of equipment manufacturing. The sealing ring cutting device comprises an annularrail mounted on the outer side of a sealing ring, a cutting machine mounted on the annular rail, and a first motor connected with the cutting machine to drive the cutting machine to move along the annular rail. According to the sealing ring cutting device, the rail and the cutting machine are arranged on the outer side of the sealing ring, automatic cutting on the sealing ring is achieved, and theproblem that an operator receives a lot of irradiation dose in an existing sealing ring cutting process is solved.

Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing, and in particular relates to a sealing ring cutting device and a cutting method thereof. Background technique [0002] In the actual manufacturing and testing process, the electric canned main pump has strict requirements on the operating parameters and often has abnormalities. In order to ensure the safe and reliable operation of the power plant, it is necessary to reserve the maintenance technology of the canned main pump. The canned main pump usually adopts an upright layout. The pump casing is welded to the lower head of the steam generator as a whole, and the rest of the components are connected to the pump casing through bolts. This detachable structure design makes it easy to disassemble, move and disassemble it when necessary. possible. In order to prevent the leakage of reactor coolant, the shielded main pump is designed with a non-pressure-bearing sealing ring between t...
