產(chǎn)品詳情
發(fā)動機功率足夠，運轉(zhuǎn)正常，而機器速度緩慢，挖掘無力1、挖掘機的液壓泵為柱塞變量泵，工作一定時間后，泵內(nèi)部液壓元件（缸體、柱塞、配流盤、九孔板、龜背等）不可避免的產(chǎn)生過度磨損，造成大量內(nèi)漏，各參數(shù)據(jù)不協(xié)調(diào)，導(dǎo)致流量不足油溫過高，速度緩慢，不能建立起高壓，所以動作緩慢挖掘無力。對于這類情況的毛病，須卸下液壓泵，送交本公司調(diào)試中心，打開液壓泵進行數(shù)據(jù)測量，確認挖機問題所在，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，上泵閥校驗臺調(diào)試。匹配各系統(tǒng)軟參數(shù)（壓力、流量、扭矩、功率等）即可。2
