norgren氣缸采用的工作介質(zhì)是壓縮空氣,其特點(diǎn)是動(dòng)作快,但速度不易控制,當(dāng)載荷變化較大時(shí),容易產(chǎn)生“爬行”或“自走”現(xiàn)象;而液壓缸采用的工作介質(zhì)是通常認(rèn)為不可壓縮的液壓油,其特點(diǎn)是動(dòng)作不如norgren氣缸快,但速度易于控制,當(dāng)載荷變化較大時(shí),采用措施得當(dāng),一般不會(huì)產(chǎn)生“爬行”和“自走”現(xiàn)象。把norgren氣缸與液壓缸巧妙組合起來(lái),取長(zhǎng)補(bǔ)短,即成為氣動(dòng)系統(tǒng)中普遍采用的氣-液阻尼缸。氣-液阻尼缸工作原理。實(shí)際是norgren氣缸與液壓缸串聯(lián)而成,兩活塞固定在同一活塞桿上。液壓缸不用泵供油,只要充滿油即可,其進(jìn)出口間裝有液壓?jiǎn)蜗蜷y、節(jié)流閥及補(bǔ)油杯。當(dāng)norgren氣缸右端供氣時(shí),norgren氣缸克服載荷帶動(dòng)液壓缸活塞向左運(yùn)動(dòng)(norgren氣缸左端排氣),此時(shí)液壓缸左端排油,單向閥關(guān)閉,油只能通過(guò)節(jié)流閥流入液壓缸右腔及油杯內(nèi),這時(shí)若將節(jié)流閥閥口開(kāi)大,則液壓缸左腔排油通暢,兩活塞運(yùn)動(dòng)速度就快,反之,若將節(jié)流閥閥口關(guān)小,液壓缸左腔排油受阻,兩活塞運(yùn)動(dòng)速度會(huì)減慢。這樣,調(diào)節(jié)節(jié)流閥開(kāi)口大小,就能控制活塞的運(yùn)動(dòng)速度。
