真(zhen)空(kong)(kong)泵(beng)(beng)原(yuan)因,這與人有病(bing)要(yao)去醫(yi)治的(de)簡單道理一(yi)樣,因為真(zhen)空(kong)(kong)泵(beng)(beng)維(wei)修(xiu)(xiu)是真(zhen)空(kong)(kong)泵(beng)(beng)管理的(de)一(yi)個重要(yao)內容(rong),一(yi)方(fang)面(mian)(mian)通(tong)過(guo)維(wei)修(xiu)(xiu)更換(huan)已損壞或可能(neng)將(jiang)損壞的(de)零部件,調整長期運行(xing)(xing)中變化了的(de)一(yi)些機械參數,使真(zhen)空(kong)(kong)泵(beng)(beng)維(wei)修(xiu)(xiu)后,真(zhen)空(kong)(kong)泵(beng)(beng)能(neng)夠提率,維(wei)持至下一(yi)維(wei)修(xiu)(xiu)周(zhou)期內不(bu)發生意外故障(zhang)。另(ling)一(yi)方(fang)面(mian)(mian)通(tong)過(guo)維(wei)修(xiu)(xiu)能(neng)幾類真(zhen)空(kong)(kong)泵(beng)(beng)管理經驗,實(shi)行(xing)(xing)對真(zhen)空(kong)(kong)泵(beng)(beng)改進的(de)措施(shi)。
