4WEH10J44/6EG24N9ETK4/B10 力士樂電液伺服閥 電液閥是由一個主閥和兩個電磁閥組成，主閥響應(yīng)速度的控制是兩個柱塞閥，安裝于主閥的入口和出口。通過兩個柱塞閥細(xì)微調(diào)節(jié)主閥的啟閉速度。調(diào)整這些裝置（柱塞閥）以控制流入和流出活塞上方介質(zhì)的流量。達(dá)到主閥啟閉速度能基于介質(zhì)的粘度及壓力調(diào)整的目的。
常開（N.O）和常閉（N.C）電磁閥分別安裝在主閥的進(jìn)油回路和出油回路中，用于控制主閥的動作，當(dāng)兩電磁閥通電時，進(jìn)油孔（上游閥）回路關(guān)閉，先導(dǎo)孔（下游閥）回路打開，活塞上腔泄壓，活塞上行，主閥打開。反之，活塞下行，主閥關(guān)閉。在主閥開啟和關(guān)閉過程中，可將流量（流速）信號及閥塞位置信號傳送給計算機，經(jīng)過計算機處理后發(fā)出相應(yīng)的指令，控制兩個電磁導(dǎo)閥的通、斷電狀態(tài)，使活塞的上下腔的液壓差產(chǎn)生變化，從而將活塞控制在所需的開啟度上，實現(xiàn)對管道介質(zhì)流量的控制。
電液比例閥簡稱比例閥。普通液壓閥只能通過預(yù)調(diào)的方式對液流的壓力、流量進(jìn)行定值控制。但是當(dāng)設(shè)備機構(gòu)在工作過程中要求對液壓系統(tǒng)的壓力、流量參數(shù)進(jìn)行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺在工作進(jìn)給時按慢、快、慢連續(xù)變化的速度實現(xiàn)進(jìn)給，或按一定精度模擬某個*控制曲線實現(xiàn)旅力控制.普通液壓閥則實現(xiàn)不了。這時可以用電液比例閥對液壓系統(tǒng)進(jìn)行控制。
電液比例閥是一種按輸入的電信號連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。它山電-機械比例轉(zhuǎn)換裝置和液壓控制閥本體兩大部分構(gòu)成.前者將輸入的電信號連續(xù)地按比例地轉(zhuǎn)換為機械力和位移輸出，后者在接受這種機械力和位移之后、按比例連續(xù)地輸出壓力和流量.
電液比例閥的發(fā)展主要有兩個途徑一是用比例電磁鐵取代傳統(tǒng)液壓閥的手動調(diào)節(jié)裝置或取代普通電磁鐵發(fā)展起來的;二是由電液伺服閥簡化結(jié)構(gòu)、降低精度發(fā)展起來的。下面介紹的比例閥均指前者，它是當(dāng)今比例閥的主流。與普通液壓閥可以互換。
比例電磁閥的結(jié)構(gòu)如圖5-27所示。比例電磁鐵是直流電磁鐵，但它與普通直流電磁鐵不同。普通直流電磁鐵的銜鐵只有吸合和斷開兩個工作位置，并且在吸合時磁路中幾乎沒有氣隙.而比例電磁鐵要求吸合力或位移與給定電流成比例。并在銜鐵的全部工作行程上，磁路中保持一定的氣隙‘.其結(jié)構(gòu)主要由極靴1、線圈2、殼體5和銜鐵10等組成。線圈2中通電后產(chǎn)生磁場，因隔磁環(huán)4的存在。使磁力線主要部分通過銜鐵10、氣隙和極靴1，形成回路口極靴對銜鐵產(chǎn)生吸力門在線圈中電流一定時。吸力的大小因極靴1與銜鐵間的距離不同而變化。但銜鐵在氣隙適中的一段行程中，吸力隨位置的改變發(fā)生的變化很小。
設(shè)計中就使比例電磁鐵的銜鐵在這段行程中工作。因此。改變線圈中的電流，即可在銜鐵上得到與其成正比的吸力。用比例電磁鐵代替螺旋手柄來調(diào)整液壓閥，就能使輸出樂力或流量與輸人電流對應(yīng)成比例地發(fā)生變化。
比例閥用于模擬控制，是介于普通開關(guān)控制與伺服控制之間的控制方式，它也特別適合于
設(shè)備的革新或改造。使設(shè)備自動化控制水平大為提高。其在現(xiàn)代液雌系統(tǒng)中占比例很大口
與普通液壓閥相比.比例閥的優(yōu)點是①能簡單地實現(xiàn)遠(yuǎn)距離控制②能連續(xù)地、按比例地控制液壓系統(tǒng)的壓力和流量。從而實現(xiàn)對執(zhí)行機構(gòu)的位置、速度和力的連續(xù)控制，并能防止或減小壓力、速度變換時的沖擊;③油路簡化，元件數(shù)量少。
比例閥適用于既要求能連續(xù)控制脹力、流量.和方向.而又不需要很I的控制精度的場合。
比例閥也分為壓力閥、流量閥和方向閥幾大類。近來又出現(xiàn)了功能復(fù)合化的趨勢。

液壓站又稱液壓泵站，是獨立的液壓裝置，它按驅(qū)動裝置（主機）要求供油，并控制油流的方 向、壓力和流量，它適用于主機與液壓裝置可分離的各種液壓機械下。 用戶購買后只要將液壓站與 主機上的執(zhí)行機構(gòu)（油缸和油馬達(dá)）用油管相連，液壓機械即可實現(xiàn)各種規(guī)定的動作、工作循環(huán)。
液壓站[The hydraulic pressure stands ]液壓站是由液壓泵、驅(qū)動用電動機、油箱、溢流閥等構(gòu)成的液壓源裝置或包括控制閥在內(nèi)的液壓裝置。按驅(qū)動裝置要求的流向、壓力和流量供油，適用于驅(qū)動裝置與液壓站分離的各種機械上，將液壓站與驅(qū)動裝置（油缸或馬達(dá)）用油管相連，液壓系統(tǒng)既可實現(xiàn)各種規(guī)定的動作。工作原理電機帶動油泵工作提供壓力源，通過集成塊、液壓閥等對驅(qū)動裝置（油缸或馬達(dá)）進(jìn)行方向、壓力、流量的調(diào)節(jié)和控制，實現(xiàn)各種規(guī)定動作。

液壓站組成及工作原理
液壓站又稱液壓泵站，是獨立的液壓裝置，它按驅(qū)動裝置（主機）要求供油，并控制油流的方 向、壓力和流量，它適用于主機與液壓裝置可分離的各種液壓機械下。
用戶購買后只要將液壓站與 主機上的執(zhí)行機構(gòu)（油缸和油馬達(dá)）用油管相連，液壓機械即可實現(xiàn)各種規(guī)定的動作、工作循環(huán)。 液壓站是由泵裝置、集成塊或閥組合、油箱、電氣盒組合而成。
各部件功用如下
泵裝置——上裝有電機和油泵，它是液壓站的動力源，將機械能轉(zhuǎn)化為液壓油的動力能。
集成塊——是由液壓閥及通道體組合而成。它對液壓油實行方向、壓力、流量調(diào)節(jié)。
閥組合——是板式閥裝在立板上，板后管連接，與集成塊功能相同。
油 箱——是鋼板焊的半封閉容器，上還裝有濾油網(wǎng)、空氣濾清器等，它用來儲油、油的冷卻 及過濾。
電器盒 ——分兩種形式。
一種設(shè)置外接引線的端子板；一種是配置了全套控制電器。
液壓站的工作原理如下
電機帶動油泵旋轉(zhuǎn)，泵從油泵中吸油后打油，將機械能轉(zhuǎn)化為液壓油 的壓力能，液壓油通過集成塊（或閥組合）被液壓閥實現(xiàn)了方向、壓力、流量調(diào)節(jié)后經(jīng)外接管路傳 輸?shù)揭簤簷C械的油缸或油馬達(dá)中，從而控制了液動機方向的變換、力量的大小及速度的快慢，推動 各種液壓機械做功。
液壓站結(jié)構(gòu)形式及主要技術(shù)參數(shù)
液壓站的結(jié)構(gòu)形式，主要以泵裝置的結(jié)構(gòu)形式、安裝位置及冷卻方式來區(qū)分，按泵裝置的機構(gòu)
形式安裝位置可分三種
1、上置立式泵裝置立式安裝在油箱蓋板上，主要用于定量泵系統(tǒng)一思想
2、上置臥式泵裝置臥式安裝在油箱蓋板上，主要用于變量泵系統(tǒng)，以便于流量調(diào)節(jié)。
3、旁置式泵裝置臥式安裝在油箱旁單獨的基礎(chǔ)上，旁置式可裝備備用泵，主要用于油箱容量 大250升，電機功率7.5千瓦以上的系統(tǒng)。
按站的冷卻方式可分為兩種
1、自然冷卻靠油箱本身與空氣熱交換冷卻，一般用于油箱容量小于250升的系統(tǒng)一思想。4WEH22H76/6SG24N9EK4/B10
2、強迫冷卻采取冷卻器進(jìn)行強制冷卻，一般用于油箱容量大于250升的系統(tǒng)。 液壓站以油箱的有效貯油量度及電機功率為主要技術(shù)參數(shù)。 油箱容量共有18種規(guī)格（單位升/L） 25、40、63、100、160、250、400、630、800、1000、1250、1600、2000、2500、3200 、4000、5000、6000 本系列液壓站根據(jù)用戶要求及依據(jù)工況使用條件，可以做到 1、按系統(tǒng)配置集成塊，也可不帶集成塊。 2、可設(shè)置冷卻器、加熱器、蓄能器 3、可設(shè)置電氣控制裝，也可不帶電氣控制裝置
