礦油型液壓油潤滑性和防銹性好，粘度等級范圍較寬，因而在液壓系統(tǒng)中應(yīng)用很廣。據(jù)統(tǒng)計(jì)，目前有90%以上的液壓系統(tǒng)采用礦油型液壓油作為工作介質(zhì)。
3.液壓油的選擇
液壓油的選擇，首先是油液品種的選擇。選擇油液品種時(shí)，優(yōu)先選購產(chǎn)品推薦的專用液壓油，這是保證設(shè)備工作可靠性和壽命的關(guān)鍵，如果確無專用液壓油，可根據(jù)工作壓力及工作溫度范圍等因素進(jìn)行考慮。對于垃圾車液壓系統(tǒng)建議優(yōu)先選用L-HM、L-HV油，其次對于一些無貴重液壓元件的壓力不高的液壓系統(tǒng)（如一般的自卸車）無法夠得上述液壓油時(shí)，可用L-HL普通液壓油，盡量不采用L-HH油（全損耗系統(tǒng)用油）。
確定了液壓油的品種之后，就要選擇油的粘度等級（液壓油的牌號）。粘度等級的選擇十分重要的，因?yàn)檎扯葘σ簤合到y(tǒng)工作的穩(wěn)定性、可靠性、效率、溫升以及磨損都有顯著的影響。粘度高的液壓油流動(dòng)時(shí)產(chǎn)生的阻力較大，克服阻力所消耗的功率較大，功率又將轉(zhuǎn)化為熱量造成油溫上升；粘度太低，會(huì)使泄漏量增大，系統(tǒng)的容積效率降低，也會(huì)造成系統(tǒng)溫升加快。
派克BD系列閥具有相同的結(jié)構(gòu)特點(diǎn)，它們由三部分組成：電氣力矩馬達(dá)、雙噴嘴先導(dǎo)級和滑閥第二級。
力矩馬達(dá)：力矩馬達(dá)包括電氣線圈、極靴和銜鐵組件。銜鐵裝在一個(gè)倒置的撓性管上，撓性管也在力矩馬達(dá)和閥的液壓段之間起流體密封作用。
先導(dǎo)級：倒置的U型架固定在銜鐵軸上并且置于兩個(gè)噴嘴之間。銜鐵運(yùn)動(dòng)通過軸傳送到倒置架，改變噴嘴的開啟，產(chǎn)生壓差。架腔中的機(jī)械反饋彈簧消除來自高速回流在反饋機(jī)構(gòu)周圍的湍流狀況。
第二級：這個(gè)區(qū)域控制輸出流量。通過精確匹配閥芯和閥體上的過流銳邊，使過流窗口口打開和關(guān)閉。打開供油壓力至控制口C1或C2,流體將通過閥流出控制口返回。這個(gè)閥芯閥/閥體的過流面積是由牢固裝在閥芯和先導(dǎo)級機(jī)械反饋彈簧上的反饋桿來控制的。
工作過程：當(dāng)力矩馬達(dá)沒有電信號輸入時(shí)，銜鐵位于極靴氣隙中間，平衡永久磁鐵的磁性力，當(dāng)有電流加在線圈上時(shí)，銜鐵與控制信號成比例地偏轉(zhuǎn)，產(chǎn)生一個(gè)順時(shí)針或逆時(shí)針運(yùn)動(dòng)，方向取決于輸入控制信號的極性。形成的力矩轉(zhuǎn)動(dòng)兩噴嘴之間的U型架，引起壓力的變化而移動(dòng)閥芯的位置，導(dǎo)致線性的流量輸出，反饋桿和機(jī)械彈簧組件提供一個(gè)與力矩馬達(dá)力相反的力，使閥芯產(chǎn)生相對于電信號的可重復(fù)的比例運(yùn)動(dòng)。
