插裝閥主要組合與功能
1、插裝方向控制閥
插裝閥可以組合成各式方向控制閥。
1)作單向閥
將x腔和A或B腔連通,即成為單向閥。連接方法不同,其導(dǎo)通方式也不同。若在控制蓋板上如圖5c連接一個(gè)二位三通液動(dòng)換向閥,即可組成液控單向閥。
2)
作二位二通閥
二位三通閥,即可組成二位二通電液閥。
3)作二位三通閥
連接二位四通閥,即可組成二位三通電液換向閥。
4)作二位四通閥
連接二位四通閥,即可組成二位四通電液換向閥。
5)作三位四通閥0型換向閥
連接三位四通閥換向閥和單向閥,即可組成三位四通閥中位為0型電液換向閥。
6)作多機(jī)能四通閥
連接換向閥,利用對(duì)電磁換向閥的控制實(shí)現(xiàn)多機(jī)能功能。
裝載機(jī)是一種廣泛用于公路、鐵路、建筑、水電、港口、礦山等建設(shè)工程的土石方施工機(jī)械,它主要用于鏟裝土壤、砂石、石灰、煤炭等散狀物料,也可對(duì)礦石、硬土等作輕度鏟挖作業(yè)。換裝不同的輔助工作裝置還可進(jìn)行推土、起重和其他物料如木材的裝卸作業(yè)。
在道路、特別是在高等級(jí)公路施工中,裝載機(jī)用于路基工程的填挖、瀝青混合料和水泥混凝土料場(chǎng)的集料與裝料等作業(yè)。此外還可進(jìn)行推運(yùn)土壤、刮平地面和牽引其他機(jī)械等作業(yè)。由于裝載機(jī)具有作業(yè)速度快、效率高、機(jī)動(dòng)性好、操作輕便等優(yōu)點(diǎn),因此它成為工程建設(shè)中土石方施工的主要機(jī)種之一。
包括發(fā)動(dòng)機(jī),變矩器,變速箱,前、后驅(qū)動(dòng)橋,簡稱四大件1. 發(fā)動(dòng)機(jī)2. 變矩器上有三個(gè)泵,工作泵(供應(yīng)舉升,翻斗壓力油)轉(zhuǎn)向泵(供應(yīng)轉(zhuǎn)向壓力油)變速泵也稱行走泵(供 應(yīng)變矩器,變速箱壓力油),有些機(jī)型轉(zhuǎn)向泵上還裝有先導(dǎo)泵(供應(yīng)操縱閥先導(dǎo)壓力油)3.工作液壓油路,液壓油箱,工作泵,多路閥,舉升油缸和翻斗油缸4. 行走油路:變速箱油底殼油,行走泵,一路進(jìn)變矩器一路進(jìn)檔位閥,變速箱離合器5. 驅(qū)動(dòng):傳動(dòng)軸,主差速器,輪邊減速器6. 轉(zhuǎn)向油路:油箱,轉(zhuǎn)向泵,穩(wěn)流閥(或者優(yōu)先閥)轉(zhuǎn)向器,轉(zhuǎn)向油缸7. 變速箱有一體的(行星式)和分體(定軸式)兩種。
林業(yè)機(jī)械是用于營林(包括造林、育林和護(hù)林)、木材切削和林業(yè)起重輸送的機(jī)械。廣義的林業(yè)機(jī)械還包括木材加工機(jī)械、人造板機(jī)械和林產(chǎn)化工設(shè)備等綜合利用機(jī)械。林業(yè)機(jī)械大多是在移動(dòng)情況下進(jìn)行露天作業(yè),因受自然條件的影響而具有一定的區(qū)域性。營林機(jī)械包括種子采集和處理、林地清理、整地、育苗、中幼林撫育和林木保護(hù)等作業(yè)用的機(jī)械。其中常用的有采種機(jī)、割灌機(jī)、挖坑機(jī)、筑床機(jī)、插條機(jī)、植樹機(jī)等。
林業(yè)機(jī)械是用于營林(包括造林、育林和護(hù)林)、木材切削和林業(yè)起重輸送的機(jī)械。廣義的林業(yè)機(jī)械還包括木材加工機(jī)械、人造板機(jī)械和林產(chǎn)化工設(shè)備等綜合利用機(jī)械。
挖掘機(jī),又稱挖掘機(jī)械,又稱挖土機(jī),是用鏟斗挖掘高于或低于承機(jī)面的物料,并裝入運(yùn)輸車輛或卸至堆料場(chǎng)的土方機(jī)械。
挖掘機(jī)挖掘的物料主要是土壤、煤、泥沙以及經(jīng)過預(yù)松后的土壤和巖石。從近幾年工程機(jī)械的發(fā)展來看,挖掘機(jī)的發(fā)展相對(duì)較快,挖掘機(jī)已經(jīng)成為工程建設(shè)中主要的工程機(jī)械之一。 挖掘機(jī)重要的三個(gè)參數(shù):操作重量(質(zhì)量),發(fā)動(dòng)機(jī)功率和鏟斗斗容。

電磁換向閥在液壓系統(tǒng)中的作用是用來實(shí)現(xiàn)液壓油路的換向、順序動(dòng)作及卸荷等。由于電磁鐵的推力有限,電磁換向閥應(yīng)用在流量不大的液壓系統(tǒng)中。
電磁換向閥是液壓控制系統(tǒng)和電氣控制系統(tǒng)之轉(zhuǎn)換元件。它由液壓機(jī)械中的按鈕開關(guān)、限位開關(guān)、行程開關(guān)、壓力繼電器等電氣元件發(fā)出信號(hào),使電磁鐵通電吸合或斷電釋放,從而直接控制閥芯移位,來實(shí)現(xiàn)油流的溝通、切斷和方向變換,來操縱各執(zhí)行機(jī)構(gòu)的動(dòng)作。推動(dòng)故障檢查按鈕可使滑閥閥芯手推移動(dòng)。
電磁閥產(chǎn)品是自控系統(tǒng)中不可缺少的執(zhí)行器元件。由于電磁閥體積小,開關(guān)速度快,接線簡單,功耗低,性價(jià)比高,經(jīng)濟(jì)實(shí)用等顯著特點(diǎn)而被普遍運(yùn)用于自控領(lǐng)域的各個(gè)環(huán)節(jié),發(fā)揮著巨大的作用。電磁閥是一-種流體控制閥,盡管其優(yōu)勢(shì)眾多,但選型的準(zhǔn)確與否直接影響到閥門本身的使用效果及系統(tǒng)的穩(wěn)定,甚至?xí)o整個(gè)自控系統(tǒng)帶來嚴(yán)重后果。較機(jī)械設(shè)備上常用的氣動(dòng)電磁閥及液壓電磁閥相比,管路系統(tǒng)中的流體電磁閥在選型上及使用上均比單一介質(zhì)復(fù)雜許多。
電磁閥之所以歸劃于自動(dòng)化儀表行業(yè)中的執(zhí)行器部分,雖外表與其他-些手動(dòng)閥相似,甚至略顯粗糙,但內(nèi)部結(jié)構(gòu)卻十分精細(xì),與一般手動(dòng)閥門有著本質(zhì)的區(qū)別。打個(gè)簡單的比喻來說,普通手動(dòng)閥的開關(guān)完全靠人工用力的大小來操作,而電磁閥則完全靠自身的功能達(dá)到控制目的,而非人力所為再者電磁閥區(qū)別于其他閥門的是因?yàn)閮?nèi)部結(jié)構(gòu)不同,所以不同的工作介質(zhì)不能通用一種閥門,一旦確定介質(zhì)種類而選定的產(chǎn)品則不能與不同介質(zhì)混用,否則會(huì)導(dǎo)致電磁閥失靈或損壞。
液壓挖掘機(jī)主要由發(fā)動(dòng)機(jī)、液壓系統(tǒng)、工作裝置、行走裝置和電氣控制等部分組成。液壓系統(tǒng)由液壓泵、控制閥、液壓缸、液壓馬達(dá)、管路、油箱等組成。電氣控制系統(tǒng)包括監(jiān)控盤、發(fā)動(dòng)機(jī)控制系統(tǒng)、泵控制系統(tǒng)、各類傳感器、電磁閥等。
液壓挖掘機(jī)一般由工作裝置、上部車體和下部車體三大部分組成。據(jù)其構(gòu)造和用途可以區(qū)分為:履帶式、輪胎式、步履式、全液壓、半液壓、全回轉(zhuǎn)、非全回轉(zhuǎn)、通用型、型、鉸接式、伸縮臂式等多種類型。
工作裝置是直接完成挖掘任務(wù)的裝置。它由動(dòng)臂、斗桿、鏟斗等三部分鉸接而成。為了適應(yīng)各種不同施工作業(yè)的需要,液壓挖掘機(jī)可以配裝多種工作裝置,如挖掘、起重、裝載、平整、夾鉗、推土,旋挖鉆等多種作業(yè)機(jī)具。
回轉(zhuǎn)與行走裝置是液壓挖掘機(jī)的機(jī)體,轉(zhuǎn)臺(tái)上部設(shè)有動(dòng)力裝置和傳動(dòng)系統(tǒng)。發(fā)動(dòng)機(jī)是液壓挖掘機(jī)的動(dòng)力源,大多采用柴油要在方便的場(chǎng)地, 也可改用電動(dòng)機(jī)。
液壓傳動(dòng)系統(tǒng)通過液壓泵將發(fā)動(dòng)機(jī)的動(dòng)力傳遞給液壓馬達(dá)、液壓缸等執(zhí)行元件,推動(dòng)工作裝置動(dòng)作,從而完成各種作業(yè)。
挖掘機(jī)械一般由動(dòng)力裝置、傳動(dòng)裝置、行走裝置和工作裝置等組成。單斗挖掘機(jī)和斗輪挖掘機(jī)還有轉(zhuǎn)臺(tái),多斗挖掘機(jī)還有物料輸送裝置。動(dòng)力裝置有柴油機(jī)、電動(dòng)機(jī)、柴油發(fā)電機(jī)組或外電源變流機(jī)組。柴油機(jī)和電動(dòng)機(jī)大多用于中、小型挖掘機(jī)械,用一臺(tái)原動(dòng)機(jī)集中驅(qū)動(dòng),兩者可互換。柴油發(fā)電機(jī)組和外電源變流機(jī)組用于大、中型挖掘機(jī)械,用多臺(tái)電機(jī)分散驅(qū)動(dòng)。行走裝置主要用來支承機(jī)器、使機(jī)器變換工作位置和轉(zhuǎn)移作業(yè)場(chǎng)地;另外,鏈斗式挖掘機(jī)和環(huán)輪式挖掘機(jī)的鏟斗,隨著行走裝置的連續(xù)行走而切削土壤。行走裝置有履帶式、輪胎式、步行式、軌行式、浮游式和拖掛式等幾種。作業(yè)場(chǎng)地固定、要求接地比壓較低時(shí)用履帶式;作業(yè)場(chǎng)地多變時(shí)用輪胎式;因施工條件特殊而必須架設(shè)軌道時(shí),用軌行式;挖掘水下泥土用浮游式;小型單斗挖掘機(jī)的行走裝置無動(dòng)力源時(shí),用拖掛式;作業(yè)場(chǎng)地固定、機(jī)器重量大時(shí),用步行式。步行式行走裝置大多用于單斗挖掘機(jī)中的大、中型拉鏟挖掘機(jī)和斗輪挖掘機(jī)。
工作裝置是液壓挖掘機(jī)的主要組成部分,挖掘機(jī)配置的是反鏟工作裝置,它主要用于挖掘停機(jī)面以下的土壤,但也可以挖掘*大切削高度以下的土壤,除了可以挖坑、開溝、裝載外還可以進(jìn)行簡單平整場(chǎng)地工作。挖掘作業(yè)適應(yīng)于開挖Ⅰ~Ⅳ級(jí)土,Ⅴ級(jí)以上用液壓錘或需爆破手段。反鏟工作裝置由動(dòng)臂、斗桿、鏟斗、搖桿、連桿及包含動(dòng)臂油缸、斗桿油缸、鏟斗油缸在內(nèi)的工作裝置液壓管路等主要部分組成。
