HED8OH-2X/100K14力士樂壓力繼電器?壓力繼電器 由線圈和舌簧管構(gòu)成的一種結(jié)構(gòu)較簡(jiǎn)單的電磁繼電器(圖4 舌簧繼電器典型結(jié)構(gòu)圖)。舌簧管是由兩根或三根高導(dǎo)磁材料制成的舌簧片封結(jié)在玻璃管中構(gòu)成的。舌簧片可構(gòu)成磁路的一部分。封結(jié)在玻璃管內(nèi)的舌簧片自由端電鍍一層貴金屬,因此它又可作為繼電器的觸點(diǎn)起開閉電路的作用。線圈激勵(lì)通電后,封結(jié)在玻璃管兩端的舌簧片被磁化,管內(nèi)兩簧片的自由端相互吸引而閉合,使被控電路接通;線圈斷電后,磁路中磁通消失,兩舌簧片在本身
機(jī)械應(yīng)力的作用下回彈而分開,使被控電路切斷。作為觸點(diǎn)的舌簧片一端被封結(jié)在玻璃管內(nèi),可以避免污染物對(duì)觸點(diǎn)可靠工作的影響。觸點(diǎn)間浸潤(rùn)水晶的叫水晶濕式舌簧繼電器。

HED8OH-2X/100K14力士樂壓力繼電器力士樂REXROTH壓力傳感器 力士樂壓力繼電器
1.壓力繼電器,液壓術(shù)語(yǔ),是液壓系統(tǒng)中當(dāng)流體壓力達(dá)到預(yù)定值時(shí),使電接點(diǎn)動(dòng)作的元件。
2.是將壓力轉(zhuǎn)換成電信號(hào)的液壓元器件,客戶根據(jù)自身的壓力設(shè)計(jì)需要,通過調(diào)節(jié)壓力繼電器,實(shí)現(xiàn)在某一設(shè)定的壓力時(shí),輸出一個(gè)電信號(hào)的功能。壓力繼電器是利用液體的壓力來啟閉電氣觸點(diǎn)的液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的調(diào)定值時(shí),發(fā)出電信號(hào),使電氣元件(如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等)動(dòng)作,使油路卸壓、換向,執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作,或關(guān)閉電動(dòng)機(jī)使系統(tǒng)停止工作,起安全保護(hù)作用等。
當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí),推動(dòng)柱塞2上移,此位移通過杠桿放大后推動(dòng)微動(dòng)開關(guān)4動(dòng)作。改變彈簧1的壓縮量,可以調(diào)節(jié)繼電器的動(dòng)作壓力。
注意: 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。若將壓力繼電器放在回油路上,由于回油路直接接回油箱,壓力也沒有變化,所以壓力繼電器也不會(huì)工作。

電磁閥(Electromagnetic valve)是用電磁控制的工業(yè)設(shè)備,是用來控制流體的自動(dòng)化基礎(chǔ)元件,屬于執(zhí)行器,并不限于液壓、氣動(dòng)。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制,而控制的精度和靈活性都能夠保證。電磁閥有很多種,不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用,最常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。
電磁閥里有密閉的腔,在不同位置開有通孔,每個(gè)孔連接不同的油管,腔中間是活塞,兩面是兩塊電磁鐵,哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊,通過控制閥體的移動(dòng)來開啟或關(guān)閉不同的排油孔,而進(jìn)油孔是常開的,液壓油就會(huì)進(jìn)入不同的排油管,然后通過油的壓力來推動(dòng)油缸的活塞,活塞又帶動(dòng)活塞桿,活塞桿帶動(dòng)機(jī)械裝置。這樣通過控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動(dòng)。
柱塞泵是液壓系統(tǒng)的一個(gè)重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動(dòng),使密封工作容腔的容積發(fā)生變化來實(shí)現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點(diǎn),被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場(chǎng)合,諸如液壓機(jī)、工程機(jī)械和船舶中。機(jī)械分類 ? 軸向式 ? 直軸斜盤式 ?? 徑向式 ? 液壓式 柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。
另一種是連續(xù)控制:閥口可以根據(jù)需要打開任意一個(gè)開度,由此控制通過流量的大小,這類閥有手動(dòng)控制的,如節(jié)流閥,也有電控的,如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是:以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等),既然是節(jié)流控制,就必然有能量損失,伺服閥和其它閥不同的是,它的能量損失更大一些,因?yàn)樗枰欢ǖ牧髁縼砭S持前置級(jí)控制油路的工作。
換向閥是具有兩種以上流動(dòng)形式和兩個(gè)以上油口的方向控制閥。是實(shí)現(xiàn)液壓油流的溝通、切斷和換向,以及壓力卸載和順序動(dòng)作控制的閥門。
工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸,帶動(dòng)搖拐臂,啟動(dòng)閥板,使工作流體時(shí)而從左入口通向閥的下部出口,時(shí)而從右入口變換通向下部出口,實(shí)現(xiàn)了周期變換流向的目的。
這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用,在合成氨造氣系統(tǒng)中最為常用。此外,換向閥還可作成閥瓣式的結(jié)構(gòu),多用于較小流量的場(chǎng)合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過閥瓣來變換工作流體的流向。
主要作用編輯定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí),會(huì)使流量需求減小。此時(shí)溢流閥開啟,使多余流量溢回油箱,保證溢流閥進(jìn)口壓力,即泵出口壓力恒定(閥口常隨壓力波動(dòng)開啟)。
節(jié)流閥是通過改變節(jié)流截面或節(jié)流長(zhǎng)度以控制流體流量的閥門。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡(jiǎn)易的流量控制閥,在定量泵液壓系統(tǒng)中,節(jié)流閥和溢流閥配合,可組成三種節(jié)流調(diào)速系統(tǒng),即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒有流量負(fù)反饋功能,不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定,一般僅用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不高的場(chǎng)合。
齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動(dòng)來輸送液體或使之增壓的回轉(zhuǎn)泵。由兩個(gè)齒輪、泵體與前后蓋組成兩個(gè)封閉空間,當(dāng)齒輪轉(zhuǎn)動(dòng)時(shí),齒輪脫開側(cè)的空間的體積從小變大,形成真空,將液體吸入,齒輪嚙合側(cè)的空間的體積從大變小,而將液體擠入管路中去。吸入腔與排出腔是靠?jī)蓚€(gè)齒輪的嚙合線來隔開的。齒輪泵的排出口的壓力完全取決于泵出處阻力的大小。
工作原理編輯葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí),葉片在離心力和壓力油的作用下,尖部緊貼在定子內(nèi)表面上。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積,先由小到大吸油后再由大到小排油,葉片旋轉(zhuǎn)一周時(shí),完成兩次吸油與排油。
單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥,它與單向閥相同,用以防止油液反向流動(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓,打開單向閥,使油流在兩個(gè)方向都可流動(dòng)。液控單向閥采用錐形閥芯,因此密封性能好。在要求封閉油路時(shí),可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無背壓的油路中可用內(nèi)泄式;否則需用外泄式,以降低控制油壓力。
壓力繼電器,液壓術(shù)語(yǔ),是液壓系統(tǒng)中當(dāng)流體壓力達(dá)到預(yù)定值時(shí),使電接點(diǎn)動(dòng)作的元件。
2.是將壓力轉(zhuǎn)換成電信號(hào)的液壓元器件,客戶根據(jù)自身的壓力設(shè)計(jì)需要,通過調(diào)節(jié)壓力繼電器,實(shí)現(xiàn)在某一設(shè)定的壓力時(shí),輸出一個(gè)電信號(hào)的功能。
