style="text-indent:25px">一個(gè)液壓系統(tǒng)工作是否正常，關(guān)鍵取決于兩個(gè)主要工作參數(shù)即壓力和流量是否處于正常的工作狀態(tài)，以及系統(tǒng)溫度和執(zhí)行器速度等參數(shù)的正常與否。液壓系統(tǒng)的故障現(xiàn)象是各種各樣的，故障原因也是多種因素的綜合。同一因素可能造成不同的故障現(xiàn)象，而同一故障又可能對(duì)應(yīng)著多種不同原因。例如：油液的污染可能造成液壓系統(tǒng)壓力、流量或方向等各方面的故障，這給液壓系統(tǒng)故障診斷帶來(lái)極大困難。參數(shù)測(cè)量法診斷故障的思路是這樣的，任何液壓系統(tǒng)工作正常時(shí)，系統(tǒng)參數(shù)都工作在設(shè)計(jì)和設(shè)定值附近，工作中如果這些參數(shù)偏離了預(yù)定值，則系統(tǒng)就會(huì)出現(xiàn)故障或有可能出現(xiàn)故障。即液壓系統(tǒng)產(chǎn)生故障的實(shí)質(zhì)就是系統(tǒng)工作參數(shù)的異常變化。因此當(dāng)液壓系統(tǒng)發(fā)生故障時(shí)，必然是系統(tǒng)中某個(gè)元件或某些元件有故障，進(jìn)一步可斷定回路中某一點(diǎn)或某幾點(diǎn)的參數(shù)已偏離了預(yù)定值。液壓系統(tǒng)的作用為通過(guò)改變壓強(qiáng)增大作用力。遼寧液壓調(diào)節(jié)閥價(jià)位</p><p
