Embodiment Construction

[0013] The invention discloses an on-site on-site repair system for the flange sealing surface of a main pump of a nuclear power plant, which mainly includes four parts: a remote console, a main control device, a monitoring device, and a repair device. After the system is assembled and debugged, the main control device, the repair device and the The detection device is arranged inside the space of the pump room, and the remote control console is arranged outside the space of the pump room for remote monitoring and control, so as to reduce the radiation exposure of the operators.

[0014] The remote console is a mobile control platform, which is connected to the main control device through a data cable, and receives the data information fed back by the main control device in real time and sends control instructions. It is mainly used for status monitoring and safety emergency operations during the stable processing of the repair device. The remote console is equipped with an ope...

Abstract

The invention belongs to repairing equipment, and particularly relates to equipment suitable for online repair of a main pump flange sealing surface. The equipment suitable for online repair of the main pump flange sealing surface comprises a remote console, a main control device, a monitoring device and a repairing device, wherein the remote console is matched with the main control device for controlling the entire repairing equipment, the monitoring device is used for remote monitoring of the repairing equipment, and the repairing device is used for being fixed to the main pump flange sealing surface and repairing the sealing surface. The equipment has the significant effects that (1) accurate repair processing of the main pump shell flange sealing surface can be realized online at a nuclear power field; (2) processing work in a repaired area is not affected; (3) the processing requirements of various main pump flange sealing surface structures can be met, and the processing range can be adjusted; and (4) the installation of turning tools, milling cutters and grinding heads can be realized by replacing a tool holder to meet various processing requirements.

Description

technical field [0001] The application belongs to repair equipment, in particular to a device suitable for online repair of the main pump flange sealing surface. Background technique [0002] The main pump casing flange sealing surface is an important pressure-bearing boundary of the primary circuit, and its sealing quality and reliability directly affect the safe and stable operation of the main pump and the reactor. The pump casing and the hydraulic components of the main pump have been operating for a long time in an environment with high temperature, high pressure and high discharge medium, and repeatedly withstand the thermal shock and mechanical shock of the primary circuit coolant, resulting in various surface defects on the flange sealing surface (including Corrosion, dents, cracks, etc.) and micro deformation, etc., seriously affect the integrity of the pressure boundary of the main pump. In order to ensure the safety of the main pump operation, the main pump hydra...
