柱塞泵機械維護

    柱塞泵機械維護

    采用補油泵供油的柱塞泵，使用3000h後，操作人員每日需對柱塞泵檢查1-2次ci，檢jian查zha液ye壓ya泵beng運yun轉zhuan聲sheng響xiang是shi否fou正zheng常chang。如ru發fa現xian液ye壓ya缸gang速su度du下xia降jiang或huo悶men車che時shi，就jiu應ying該gai對dui補bu油you泵beng解jie體ti檢jian查zha，檢jian查zha葉ye輪lun邊bian沿yan是shi否fou有you刮gua傷shang現xian象xiang，內nei齒chi輪lun泵beng間jian隙xi是shi否fou過guo大da。對dui於yu自zi吸xi油you型xing柱zhu塞sai泵beng，液ye壓ya油you箱xiang內nei的de油you液ye不bu得de低di於yu油you標biao下xia限xian
，要yao保bao持chi足zu夠gou數shu量liang的de液ye壓ya油you。液ye壓ya油you的de清qing潔jie度du越yue高gao，液ye壓ya泵beng的de使shi用yong壽shou命ming越yue長chang。柱zhu塞sai泵beng最zui重zhong要yao的de部bu件jian是shi軸zhou承cheng

，以防銅層變薄或漏油出鋼基。柱塞泵也可用變頻器節約電能，上海正藝的工程師指出：柱zhu塞sai泵beng在zai實shi際ji生sheng產chan過guo程cheng中zhong，通tong常chang運yun行xing的de情qing況kuang下xia都dou是shi以yi壓ya力li或huo流liu量liang來lai調tiao節jie工gong作zuo狀zhuang態tai。當dang實shi際ji壓ya力li大da於yu需xu要yao壓ya力li時shi，都dou是shi通tong過guo溢yi流liu閥fa來lai調tiao節jie，使shi其qi工gong作zuo壓ya力li保bao持chi穩wen定ding讓rang溢yi流liu閥fa施shi放fang超chao出chu部bu分fen。而er電dian機ji一yi直zhi處chu於yu全quan速su運yun行xing反fan複fu動dong作zuo，功gong耗hao不bu變bian。當dang采cai用yong溢yi流liu來lai調tiao節jie壓ya力li和he流liu量liang時shi
