(或等于)160L/min的柱塞泵，不宜安裝在油箱上。對所有的液壓系統(tǒng)而言，均是由液壓執(zhí)行元件（包括液壓缸與液壓馬達）按指定要求的工作順序以實現(xiàn)循環(huán)動作，對外輸出一定的功率（壓力F×流量S），完成相應的動作，平穩(wěn)且協(xié)調的持續(xù)運行，這就必須對液壓系統(tǒng)的壓力流量和液流方向加以控制和調節(jié)。在液壓系統(tǒng)中，目前可控制和調節(jié)壓力、流量、液流方向的方式分兩種：第1種是容積式控制（泵控），第二種是節(jié)流式控制（閥控），本期我們就第二種閥控予以講解。作為一種以節(jié)流的方式以控制液壓系統(tǒng)的壓力、流量和液流方向的液壓元件，可分為三大類，即普通的通斷式開關閥、伺服閥與比例閥。木工機械先導溢流閥價格關于液壓閥的設計首先從液壓閥的設計尺寸來討論。</p><div

style="text-indent:25px">液壓控制閥按用途分為溢流閥、減壓閥和順序閥。①溢流閥：能控制液壓系統(tǒng)在達到調定壓力時保持恒定狀態(tài)。用于過載保護的溢流閥稱為安全閥。當系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時，閥口會打開而溢流，以保證系統(tǒng)的安全。②減壓閥：能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。減壓閥按它所控制的壓力功能不同，又可分為定值減壓閥（輸出壓力為恒定值）、定差減壓閥（輸入與輸出壓力差為定值）和定比減壓閥（輸入與輸出壓力間保持一定的比例）。③順序閥：能使一個執(zhí)行元件（如液壓缸、液壓馬達等）動作以后,再按順序使其他執(zhí)行元件動作。</p><p style="text-indent:25px">液壓閥裝機前應檢查安裝孔的深度是否大于泵的軸伸長度，防止產生頂軸現(xiàn)象，否則將燒毀泵。當由于各種原因，空氣被吸入油液中，或者在油液壓力低于大氣壓時，溶解在油液中的部分空氣就會析出形成氣泡，這些氣泡在低壓區(qū)時體積較大，當隨油液流到高壓區(qū)時，受到壓縮，體積突然變小或氣泡消失；反之，如在高壓區(qū)時體積本來較小，而當流到低壓區(qū)時，體積突然增大，油中氣泡體積這種急速改變的現(xiàn)象。氣泡體積的突然改變會產生噪聲，又由于這一過程發(fā)生在瞬間，將引起局部液壓沖擊而產生振動。先導式溢流閥的導閥口和主閥口，油液流速和壓力的變化很大，很容易出現(xiàn)空穴現(xiàn)象，由此而產生噪聲和振動。液壓閥的選擇要注意方向控制的選用。</p><div
