【摘要】：2016年末至2017年初,我公司對(duì)一臺(tái)其他廠家生產(chǎn)的電廠用多級(jí)鍋爐給水泵進(jìn)行了檢修。該泵主要故障為運(yùn)行500小時(shí)后出現(xiàn)了斷軸的問(wèn)題,現(xiàn)場(chǎng)檢修并更換主軸后振動(dòng)仍然較大,運(yùn)行不平穩(wěn)。將該給水泵解體后發(fā)現(xiàn)密封環(huán)間隙超標(biāo),平衡盤、平衡座磨損嚴(yán)重,最主要的問(wèn)題是現(xiàn)場(chǎng)新?lián)Q的主軸已經(jīng)彎曲變形。經(jīng)研究決定重新測(cè)量檢查、更換主軸,各葉輪密封環(huán)處加工成統(tǒng)一外徑,重新加工配制密封環(huán),在不更換葉輪的情況下實(shí)施有效的修復(fù)。對(duì)平衡盤、平衡座重新測(cè)繪加工處理,該給水泵經(jīng)過(guò)處理修復(fù)后,運(yùn)行狀況良好,達(dá)到了預(yù)期效果。
[Abstract]:From the end of 2016 to the beginning of 2017, our company overhauled a multistage boiler feedwater pump in a power plant made by other manufacturers. The main failure of the pump is the failure of the shaft after 500 hours of operation. The vibration is still large and the operation is not stable after the maintenance and replacement of the main shaft. After disintegrating the feed pump, it is found that the clearance of the seal ring exceeds the standard, and the balance disc and the balance seat are worn seriously. The main problem is that the newly changed spindle has been bent and deformed. After study, it is decided to re-measure and check, to replace the spindle, to process each impeller seal ring into uniform outer diameter, to reprocess and prepare the seal ring, and to carry out effective repair without replacing impeller. After the reprocessing of the balance plate and the balance seat, the feed pump is in good operation condition and the expected effect is achieved.
