Research On The Precision Measurement Technology Of The RCP Manufacturing

Precision measurement technology is with the development of science and technology,continuously extended a technology, not only as a judge on the basis of product quality, as well as for scientific research and technological innovation provide valuable objective data and evidence, and scientific research of itself, but for the improvement of technical level directly. Early precision measurement technology has been used in industry field, along with the advancement of nuclear reactor main equipment has been closely together with product manufacturing. Precision measurement technology has a strong applicability, at the same time,with the development of computer technology, the introduction of new equipment, it itself is constantly improve and perfect.This article through to the nuclear reactor coolant pump (main pump) in the whole manufacturing process adopted by different precision measurement technology makes a deep analysis of the research. This paper studies the laser tracking measurement method, three coordinate measuring instrument, measuring method, combination method, auxiliary measurement and other precision measuring method, in view of the main pump of different key components, combined with its characteristics and application achievements in the field of main pump manufacturing, features of different measured workpiece are classified and determine each type of precision measuring method, to choose the optimal precision measurement scheme. Through actual product validation, single precision measurement method is unable to meet the nuclear main pump manufacturing this kind of technology intensive, complicated structure, control the strict engineering requirements. Organic combination and use different precision measurement technology, find the most appropriate method of precision measurement for different parts, will be nuclear main pump manufacturing has been encountered problems for a long time.In solving problems has been in the nuclear main pump manufacturing basis, with the continuous development of nuclear technology, for the safety of the nuclear industry are also put forward higher request, therefore request in nuclear power equipment manufacturing should be strictly control the quality. For nuclear main equipment of nuclear main pump, its manufacture quality requirements should also be mentioned that a higher level. With the continuous application of new technology, new problems will emerge, the application of the latest precision measurement technology solve the problem of actual measurement, control product quality, maintain security of nuclear power products, will always is the goal of this study.
