淺談液壓系統(tǒng)常用的保壓和洩壓方法及其特點

在液壓系統(tǒng)中常用的保壓和洩壓方法及其特點。

保壓回路的功用是在液壓系統(tǒng)中的執(zhí)行元件停止工作或僅有工件變形所産生微小位移的情況下，使系統(tǒng)壓力基本保持不變。而洩壓回路則用于緩慢釋放液壓系統(tǒng)在保壓期間儲存的能量，以免突然釋放而産生液壓沖擊和噪聲。隻要系統(tǒng)具有保壓回路，通常就應(yīng)設(shè)置相應(yīng)的洩壓回路。保壓回路和洩壓回路常用于大型壓力機的液壓系統(tǒng)中。

對保壓回路的基本要求是；能夠滿足保壓時間的保壓期間壓力應(yīng)穩(wěn)定。對洩壓回路的基本要求是：洩壓時間盡量短；洩壓時振動和噪聲小。

基本的保壓回路是圖1所示利用液控單向閥的自動補油保壓回路。其工作原理爲：當電磁鐵2YA通電使換向閥3切換至右位，液壓油缸6上腔壓力上升至電接點壓力表5的上限值時，壓力表高壓觸點通電，使電磁鐵2YA斷電，換向閥複至中位，液壓泵1經(jīng)閥2的M型中位卸荷，液壓油缸由液控單向閥4保壓。

保壓期間如果液壓油缸上腔因洩漏等因素，壓力下降到電接點壓力表調(diào)定下限值（低壓觸點）時，壓力表又發(fā)出信號，使電磁鐵2YA通電，液壓泵恢複向液壓油缸上腔供油，使壓力上升。而當電磁鐵1YA通電使換向閥切換至左位時，液壓油缸活塞快速向上退回。這中回路能自動地保持液壓油缸上腔的壓力在某一范圍內(nèi)，保壓時間長，壓力穩(wěn)定性高，適用于液壓機等保壓性能要求較高的液壓系統(tǒng)。

通常液壓油缸直徑大于250mm、壓力大于7MPa時，其油腔在排油前就先需洩壓。控制洩壓可以通過延緩主換向閥的切換時間或采用液壓控制等措施實現(xiàn)。

圖2所示爲用順序閥控制回程壓力實現(xiàn)洩壓的回路。上腔沒有洩壓，壓力油經(jīng)二位二通換向閥7將順序閥5打開，液壓泵1進入缸下腔的油液經(jīng)順序閥5和節(jié)流閥6回油箱，調(diào)節(jié)節(jié)流閥6的開度，使缸下腔壓力在約2MPa還不足以使活塞回程，但能頂開液控單向閥4的卸荷閥芯，使上腔洩壓。當缸上腔壓力降低至小于順序閥5的調(diào)壓值（通常爲2～4MPa），順序閥5關(guān)閉，切斷泵1至油箱的低壓循環(huán)，泵1壓力上升，頂開液控單向閥4的主閥芯，活塞回程。二位二通閥7是爲了保壓過程中切斷順序閥5的控制油路，保證回路的保壓性能。

回路中的閥4爲帶有卸載閥芯的複式液控單向閥，保壓和洩壓均由此閥實現(xiàn)。
