產(chǎn)品詳情
發(fā)動(dòng)機(jī)功率足夠,運(yùn)轉(zhuǎn)正常,而機(jī)器速度緩慢,挖掘無(wú)力1、挖掘機(jī)的液壓泵為柱塞變量泵,工作一定時(shí)間后,泵內(nèi)部液壓元件(缸體、柱塞、配流盤(pán)、九孔板、龜背等)不可避免的產(chǎn)生過(guò)度磨損,造成大量?jī)?nèi)漏,各參數(shù)據(jù)不協(xié)調(diào),導(dǎo)致流量不足油溫過(guò)高,速度緩慢,不能建立起高壓,所以動(dòng)作緩慢挖掘無(wú)力。對(duì)于這類(lèi)情況的毛病,須卸下液壓泵,送交本公司調(diào)試中心,打開(kāi)液壓泵進(jìn)行數(shù)據(jù)測(cè)量,確認(rèn)挖機(jī)問(wèn)題所在,更換不能繼續(xù)使用的配件,修復(fù)可以繼續(xù)使用的配件,重新組裝液壓泵后,上泵閥校驗(yàn)臺(tái)調(diào)試。匹配各系統(tǒng)軟參數(shù)(壓力、流量、扭矩、功率等)即可。2
