Water pump bearing bush thermometer dismounting and mounting device for nuclear power station, and dismounting and mounting method for water pump bearing bush thermometer dismounting and mounting device

Abstract

The invention belongs to the technical field of nuclear power station rotating equipment maintenance engineering, and particularly relates to a water pump bearing bush thermometer dismounting and mounting device for a nuclear power station, and a dismounting and mounting method for the water pump bearing bush thermometer dismounting and mounting device. The water pump bearing bush thermometer dismounting and mounting device comprises a T-shaped handle and a dismounting and mounting rod, wherein the T-shaped handle is fixedly connected with the dismounting and mounting rod in a magnetic attraction manner; the dismounting and mounting rod comprises a hexagonal joint, a U-shaped groove and a U-shaped plug; the dismounting and mounting rod is of a hollow cylinder structure; the U-shaped groove is formed in the outer surface of the dismounting and mounting rod; the hexagonal joint is arranged at the top end of the dismounting and mounting rod; and the U-shaped plug is arranged at the bottom end of the dismounting and mounting rod. According to the device and the dismounting and mounting method therefor, the working time is effectively shortened, the maintenance efficiency is improved, and the irradiation time of nuclear power station workers is shortened.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant rotating equipment overhaul engineering, and in particular relates to a nuclear power plant water pump bearing bush thermometer disassembly device and a disassembly method thereof. Background technique [0002] The bearing bushes of various types of pumps and motors in a nuclear power plant are equipped with temperature-measuring sensors to protect the pump from overheating and damage the pump body when the temperature exceeds the set limit. Therefore, the bearing bush thermometer plays an important role in monitoring the operating status of the pump. In the dismantling and overhaul of pumps and motors, it is necessary to remove and install the bearing bush thermometer probe. It is not only necessary to disassemble and assemble it correctly to ensure the integrity of the thermometer probe and the extension cable, but also to protect the joint surface of the bearing bush to avoid damage ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to design a disassembly device and disassembly method for the bearing pad thermometer of a nuclear power plant, which is used to effectively solve the problem of easy damage to the protection layer at the junction of the thermometer extension line and the locking head during the disassembly process of the existing water pump bearing pad thermometer. Difficult to disassemble, and the operator may have technical problems with the risk of dose exceeding the standard due to too long disassembly and assembly time
