液壓系統(tǒng)及液壓元件介紹
一、液壓系統(tǒng)的組成:動(dòng)力部分、控制部分、執(zhí)行部分、輔助裝置 液壓泵;用以將機(jī)械能轉(zhuǎn)化為液體的壓力能,有時(shí)也將蓄能器作為緊急或輔助動(dòng)力源
各類(lèi)壓力、流量、方向等控制閥;用以實(shí)現(xiàn)對(duì)執(zhí)行元件的運(yùn)動(dòng)速度、方向、作用力等的控制、也用于實(shí)現(xiàn)過(guò)載保護(hù)、程序控制等
液壓缸、液壓馬達(dá)等;用以將液體壓力轉(zhuǎn)化為機(jī)械能
管路、蓄能器、過(guò)濾器、油箱、冷卻器、加熱器、壓力表、流量計(jì)等
二、液壓傳動(dòng)的優(yōu)點(diǎn) 質(zhì)量輕體積小 容易實(shí)現(xiàn)無(wú)級(jí)調(diào)速 易于實(shí)現(xiàn)過(guò)載保護(hù) 液壓元件能夠自動(dòng)潤(rùn)滑 簡(jiǎn)化機(jī)構(gòu) 便于實(shí)現(xiàn)自動(dòng)化
三、液壓傳動(dòng)的缺點(diǎn) 液壓元件制造精度要求高 實(shí)現(xiàn)定比傳動(dòng)困難 油液受溫度的影響 不適宜遠(yuǎn)距離輸送動(dòng)力 油液中混入空氣易影響工作性能 油液容易污染 發(fā)生故障不易檢查和排除。 四、液壓部件及圖形符號(hào)
液壓是機(jī)械行業(yè)、機(jī)電行業(yè)的一個(gè)名詞。液壓可以用動(dòng)力傳動(dòng)方式, 成為液壓傳動(dòng)。液壓也可用作控制方式,稱(chēng)為液壓控制。
液壓傳動(dòng)是以液體作為工作介質(zhì),利用液體的壓力能來(lái)傳遞動(dòng)力。
液壓控制是以有壓力液體作為控制信號(hào)傳遞方式的控制。用液壓技術(shù)構(gòu)成的控制系統(tǒng)稱(chēng)為液壓控制系統(tǒng)。液壓挖制通常包括液壓開(kāi)環(huán)挖制和液壓閉環(huán)控制。液壓閉環(huán)挖制也就是液壓伺服控制,它構(gòu)成液壓伺服系統(tǒng),通常包括電氣液壓伺服系統(tǒng)(電液伺服系統(tǒng))和機(jī)械液壓同服系統(tǒng)(機(jī)液伺服系統(tǒng),或機(jī)液伺服機(jī)構(gòu))等。
一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成,即能源裝置、執(zhí)行裝置、控制調(diào)節(jié)裝置、輔助裝置、液體介質(zhì)。液壓由于其傳遞動(dòng)力大,易于傳遞及配置等特點(diǎn),在工業(yè)、民用行業(yè)應(yīng)用廣泛。液壓系統(tǒng)的執(zhí)行元件(液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能,從而獲
得需要的直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。液壓系統(tǒng)的能源裝置(液壓泵)的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。
液壓系統(tǒng)組成
一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成,即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件和工作介質(zhì)。
動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。動(dòng)力元件指液壓系統(tǒng)中的液壓泵,它向整個(gè)液壓系統(tǒng)提供動(dòng)力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵、柱塞泵、螺桿泵。
執(zhí)行元件的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能,驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。執(zhí)行元件有液壓缸和液壓馬達(dá)。
挖制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。

液壓閥的分類(lèi):
1根據(jù)結(jié)構(gòu)形式分類(lèi)
滑閥:滑閥為間隙密封,閥芯與閥口存在一定的密封長(zhǎng)度,因此滑閥運(yùn)動(dòng)存在一個(gè)死區(qū)。
錐閥:錐閥閥芯半錐角一 般為12°-20°,閥口關(guān)閉時(shí)為線密封,密封性能好且動(dòng)作靈敏。
球閥:性能與錐閥相同
2.根據(jù)控制制方式不同分:
定值或開(kāi)關(guān)控制閥:被控制量為定值的閥類(lèi),包括普通控制閥、插裝閥、疊加閥。
比例控制閥:被控制量與輸入信號(hào)成比例連續(xù)變化的閥類(lèi),包括普通比例閥和帶內(nèi)反饋的電液比例閥。
伺服控制閥:被控制量與(輸出與輸入之間的)偏差信號(hào)成比例連續(xù)變化的閥類(lèi),包括機(jī)液伺服閥和電液伺服閥。.
數(shù)字控制閥:用數(shù)字信息直接控制閥口的啟閉,來(lái)控制液流的壓力、流
量、方向的閥類(lèi)。
3.根據(jù)用途分:
壓力控制閥、流量控制閥、方向控制閥
方向控制閥的作用:在液壓系統(tǒng)中控制液流方向。
方向控制閥包括:單向閥和換向閥
單向閥包括:普通單向閥和液控單向閥
1.普通單向閥
使油液只能沿一個(gè)方向流動(dòng),反向則被截止的方向閥。
普通單向閥的應(yīng)用
常被安裝在泵的出口,一方面防止壓力沖擊影響泵的正常工作,另一方面防止泵不工作時(shí)系統(tǒng)油液倒流經(jīng)泵回油箱。
被用來(lái)分隔油路以防止高低壓干擾。:
與其他的閥組成單向節(jié)流閥、單向減壓閥、單向順序閥等復(fù)合閥。
安裝在執(zhí)行元件的回油路上,使回油具有一定背壓。作背壓閥的單向閥應(yīng)更換剛度較大的彈簧,其正向開(kāi)啟壓力為( 0. 3~0.5) MPa。
2.液控單向閥
外泄式液控單向閥,內(nèi)泄式單向閥
工作原理:當(dāng)控制油口不通壓力油時(shí),油液只能從pi→P:當(dāng)控制油口通壓力油時(shí),正、反向的油液均可自由通過(guò)。
3.換向閥
換向閥是利用閥芯在閥體孔內(nèi)作相對(duì)運(yùn)動(dòng),使油路接通或切斷而改變油流方向的閥。
換向閥的分類(lèi)
按結(jié)構(gòu)形式可分:滑閥式、轉(zhuǎn)閥式、球閥式。
按閥體連通的主油路數(shù)可分:兩通、三通、四通...等。
按閥芯在閥體內(nèi)的工作位置可分:兩位、三位、四位等。
按操作閥芯運(yùn)動(dòng)的方式可分:手動(dòng)、機(jī)動(dòng)、電磁動(dòng)、液動(dòng)、電液動(dòng)等。
換向閥的中位機(jī)能,多位閥在不同工作位置時(shí),各油口的連通方式體現(xiàn)了換向閥的不同的控制機(jī)能,稱(chēng)之為換向閥的機(jī)能。對(duì)于三位閥,左、右位實(shí)現(xiàn)執(zhí)行元件的換向,中位則能滿足執(zhí)行元件處于非工作狀態(tài)時(shí)系統(tǒng)的不同要求。
