Circulating pump is not stable operating conditions, the pump running excessive vibration, reducingthe equipment operating life. Had to overhaul technical regulations fom the research innovation, breaking part of theconventional processes, the use of advanced technology, innovative process for the purpose of the circulating pump vibrationvalue drops, reducing the defect rate. Applications can be proved through practice inspection technology innovation toachieve tangible results, improvements in technology have practicality and maneuverability. Technological improvementsaimed at key nodes through the pump and a major overhaul process was analyzed and discussed, technological innovation.The Ministry of nearly two years of the project to improve the use of good maintenance process overhaul 3B and 3Acirculation pump qualit, vibration within 0.02 mm/s, a record of success.Key words: process method; excessive vibration; technology innovation; practical application有檢查、測量、更換等工序。拆卸工作主要是對泵1常 規檢修工藝概述體進(jìn)行解體，過(guò)程中記錄部分修前數據，作為組裝88LKXA-20型循環(huán)水泵解體檢修主要分為拆時(shí)的參考數據。如提升量、中心、支架與簡(jiǎn)體間隙卸、修理、組裝3大步驟，在整個(gè)大修過(guò)程中又含及相對位置(用塞尺測量)、電機支座水平度、電機收稿日期: 2015-07-19 .作者簡(jiǎn)介:琚烈濤(1986-), 男，江西上饒人，助理工程師，大學(xué)本科，畢業(yè)于武中國煤化工要研究方向:電力檢修技術(shù)、創(chuàng )新及管理。MYHCNMHG.
