1.1液壓技術(shù)的原理與液壓系統(tǒng)的組成

液壓傳動與控制簡稱為液壓技術(shù)，是以液體為工作介質(zhì)，利用封閉系統(tǒng)中液體的靜壓能實現(xiàn)信息、運動和動力的傳遞及工程控制的計術(shù)。由于液壓技術(shù)在功率密度，結(jié)構(gòu)組成、響應(yīng)速度，調(diào)節(jié)范圍，過載保護、電液整合等方面獨特的優(yōu)勢，使其成為現(xiàn)代傳動與控制的重要基礎(chǔ)技術(shù)之一，其應(yīng)用遍及國民經(jīng)濟各個領(lǐng)域。

除了工作介質(zhì)外，一個液壓系統(tǒng)通常都是由能源元件（液壓泵）、執(zhí)行元件（液壓缸、液壓馬達或擺動液壓馬達）、控制元件（各種液壓閥）和輔助元件

液壓控制閥（簡稱液壓閥）是液壓系統(tǒng)中的控制元件，其功用是控制液壓系統(tǒng)中液體的流向、壓力及流量，以使液壓執(zhí)行器及其驅(qū)動的工作機構(gòu)獲得所需要的運動方向、運動速度（轉(zhuǎn)速）及推力（轉(zhuǎn)矩）等。

液壓閥在液壓系統(tǒng)中起著非常總要的作用。任何一個液壓系統(tǒng)，不論其如何簡單，都不能缺少液壓閥；同一工藝目的液壓機械設(shè)備，通過液壓閥的不同組合與使用，可以組成油路結(jié)構(gòu)截然不同的多種液壓系統(tǒng)方案，股液壓閥是液壓技術(shù)中與規(guī)格最多、應(yīng)用最廣泛、最活躍的元件；一個液壓系統(tǒng)設(shè)計的合理性、安裝維護的便利性以及能否按照既定要求正常可靠地運行，在很大程度上取決于其中所采用的各種液壓閥是性能優(yōu)劣及參數(shù)匹配是否合理。

液壓閥作為液壓系統(tǒng)的控制樞紐，運動頻繁，對各組成部分器件的精度要求、密封性、可靠性都要求非常高，國外大部分企業(yè)都采用滾壓來提高精度配合，如：日本的小松機械、日立機械等，在一些重要部件圖紙中都明確要求滾壓加工。??清洗液壓元件逐步實現(xiàn)了標準化、系列化，其規(guī)格、

品種、質(zhì)量、性能都有了很大提高，尤其是采用電子技術(shù)、伺服技術(shù)等新技術(shù)新工藝后，液壓系統(tǒng)的質(zhì)量得到了顯著的提高，其在國民經(jīng)濟及軍事工業(yè)中發(fā)揮了重大作用。從不同的角度出發(fā)，可以把液壓系統(tǒng)分成不同的形式。工作壓力：輸入馬達油液的實際壓力，其大小決定于馬達的負載。油缸是工程機械最主要部件，傳統(tǒng)的加工方法是：拉削缸體——精鏜缸體——磨削缸體。采用滾壓方法?是：拉削缸體——精鏜缸體——滾壓缸體，更多技術(shù)可咨詢：?滾壓及加工1、發(fā)熱?由于傳力介質(zhì)（液壓油）在流動過程中存在各部位流速的不同，導致液體內(nèi)部存在一定的內(nèi)摩擦，同時液體和管路內(nèi)壁之間也存在摩擦，這些都是導致液壓油溫度升高的原因。溫度升高將導致內(nèi)外泄漏增大，降低其機械效率。同時由于較高的溫度，液壓油會發(fā)生膨脹，導致壓縮性增大，使控制動作無法很好的傳遞。解決辦法：發(fā)熱是液壓系統(tǒng)的固有特征，無法根除只能盡量減輕。使用質(zhì)量好的液壓油、液壓管路的布置中應(yīng)盡量避免彎頭的出現(xiàn)、使用高質(zhì)量的管路以及管接頭、液壓閥等。編輯當溢流閥在系統(tǒng)中做安全閥使用時，如果系統(tǒng)過載安全閥不能及時打開或根本打不開，也會導致系統(tǒng)管道壓力急劇升高，產(chǎn)生液壓沖擊。一個完整的

?充液閥的基本結(jié)構(gòu)主要包括閥芯、閥體和驅(qū)動閥芯在閥體內(nèi)作相對運動的操縱控制機構(gòu)。閥芯的結(jié)構(gòu)形式多樣;閥體上開設(shè)有與閥芯配合的閥體（套）孔或閥座孔，還有外接油管的進、出油口；閥芯的操縱控制機構(gòu)有手調(diào)（動）式、機械式、電動式以及液動式或電液動式等。

液壓閥的基本工作原理是：利用閥芯相對于閥體的運動來控制閥口的通斷及開度的大小（實質(zhì)是對閥口的流動阻尼進行控制），實現(xiàn)對液流方向、壓力和流量的控制。液壓閥工作時，所有閥的通過流量與閥的進、出油口間的壓力差以及開度的大小間的關(guān)系都符合如下空口壓力流量特性公式
