意大利ATOS比例閥特點： - 可實現(xian)壓力、速度的(de)無(wu)極調節，避免(mian)了常通的(de)開關式氣閥換向時的(de)沖(chong)擊(ji)現(xian)象(xiang)。
- 能實現遠程(cheng)控制(zhi)(zhi)和程(cheng)序控制(zhi)(zhi)。
- 與斷續控制相比，系統簡化，元件大大減少。
- 與(yu)液壓(ya)比例閥相比，體積小、重量輕、結構簡單、成(cheng)本較低，但響應速度比液壓(ya)系統慢得多，對負(fu)載變化也比較敏(min)感。
- 使(shi)用功率(lv)小、發熱少、噪(zao)聲(sheng)低。
- 不會發生(sheng)火災，*。受(shou)溫度變(bian)化的影響小。

LIQZO-TES-PS-162L4 ATOS阿托斯比例方向閥屬于比例閥的一種，用來控制流量和流向。 電氣(qi)比例(li)閥(fa)(fa)自動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)可分(fen)成斷續控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)連續控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷續控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開(kai)關控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣(qi)動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)中使用動(dong)(dong)作(zuo)頻率(lv)較低的(de)開(kai)關式(ON-OFF)的(de)換向(xiang)閥(fa)(fa)來(lai)(lai)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣(qi)路(lu)的(de)通斷。靠減壓(ya)閥(fa)(fa)來(lai)(lai)調(diao)節所需要(yao)的(de)壓(ya)力，靠節流(liu)閥(fa)(fa)來(lai)(lai)調(diao)節所需要(yao)的(de)流(liu)量(liang)(liang)(liang)。這種傳統(tong)的(de)氣(qi)動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)要(yao)想要(yao)有多個輸(shu)(shu)出力和(he)多個運動(dong)(dong)速度，就需要(yao)多個減壓(ya)閥(fa)(fa)、節流(liu)閥(fa)(fa)及(ji)換向(xiang)閥(fa)(fa)。這樣，不僅元件需要(yao)多，成本高，構(gou)成系(xi)統(tong)復雜，且許多元件都(dou)需要(yao)預先進(jin)行(xing)人工調(diao)節。電氣(qi)比例(li)閥(fa)(fa)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，其特點是輸(shu)(shu)出量(liang)(liang)(liang)隨輸(shu)(shu)入(ru)量(liang)(liang)(liang)的(de)變(bian)化(hua)(hua)而變(bian)化(hua)(hua)，輸(shu)(shu)出量(liang)(liang)(liang)與(yu)輸(shu)(shu)入(ru)量(liang)(liang)(liang)之間(jian)存在一(yi)定(ding)的(de)比例(li)關系(xi)。比例(li)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開(kai)環(huan)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)閉環(huan)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)之分(fen)。 |
