Problems solved by technology

However, due to the small demand, manufacturers will not mass-produce, let alone conduct functional tests on CRDM parts for individual parts, and due to the difference in claw performance due to continuous changes in manufacturing processes, there is an urgent need for a CRDM Hook performance rapid test system

Abstract

The invention relates to a quick test system for CRDM (Control Rod Drive Mechanism) claw performances. The system comprises a rack assembly, an operating unit and a control unit, wherein the operatingunit and the control unit are arranged on the rack assembly; the operating unit comprises a driving part which is connected to the rack assembly, a connecting rod of which one end is connected to thedriving part, a testing kettle assembly and a simulating assembly; the testing kettle assembly comprises a kettle body; the other end of the connecting rod passes through the kettle body; the simulating part is arranged in the kettle body; a claw sample is correspondingly connected to or matched with the other end part of the connecting rod and the simulating part. The system is used for testingthe claw only, is high in adaptability, is space and time saving, reduces cost, and is high in pertinence and capable of quickly and efficiently testing the claw performances.

Description

technical field [0001] The invention relates to CRDM, in particular to a fast testing system for the performance of CRDM claws. Background technique [0002] The Reactor Control Rod Drive Machine (CRDM) is abbreviated as CRDM. Its function is to adjust the height of the control rod in the reactor and then control the power of the reactor. There is a hole on the claw, which is connected with the drive rod sleeve through the pin shaft, and the swing in and out of the claw is realized by the relative rotation with the pin shaft. The ring tooth groove meshes with the drive rod core rod assembly, and rises and falls with the inner parts of the sleeve to realize the purpose of adjusting the position of the control rod; when the hook swings out, it is a neutral action without force. [0003] The base body of the CRDM hook claw is made of stainless steel, but its tip and the inner wall of the pin shaft hole are all surfacing hard alloys to deal with the risks mainly caused by mecha...
