Equipment suitable for online repair of main pump flange sealing surface

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...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic nuclear power plants have not carried out on-site repair work on the flange sealing surface of the main pump casing, and do not have corresponding special on-site repair equipment, so it is difficult to ensure the smooth implementation of the upcoming repair work on the flange sealing surface of the main pump casing.
