意大利ATOS比例閥特點： - 可(ke)實現壓力、速度(du)的無極(ji)調節，避免(mian)了常通的開關(guan)式(shi)氣閥換向(xiang)時(shi)的沖(chong)擊現象。
- 能實現遠程(cheng)控制和程(cheng)序控制。
- 與斷(duan)續控(kong)制相比，系統簡化，元件大大減(jian)少。
- 與液壓比例閥相比，體積小、重量(liang)輕、結構簡單、成本(ben)較低，但響應(ying)速(su)度比液壓系統慢得多，對負(fu)載變化也比較敏感。
- 使用功率小、發熱少、噪聲低。
- 不會發(fa)生(sheng)火災，*。受溫度變化的影(ying)響小。

DPZO-TE-271-S5 40? 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(bi)例閥(fa)自動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)可(ke)分成(cheng)(cheng)斷續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)和連續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開(kai)關控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)中使用動(dong)作頻率較低的(de)開(kai)關式(ON-OFF)的(de)換向閥(fa)來控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣(qi)路的(de)通斷。靠(kao)減壓(ya)(ya)閥(fa)來調(diao)(diao)節(jie)(jie)(jie)所需(xu)(xu)要(yao)(yao)(yao)的(de)壓(ya)(ya)力(li)，靠(kao)節(jie)(jie)(jie)流(liu)(liu)閥(fa)來調(diao)(diao)節(jie)(jie)(jie)所需(xu)(xu)要(yao)(yao)(yao)的(de)流(liu)(liu)量(liang)(liang)。這(zhe)種傳統(tong)的(de)氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)要(yao)(yao)(yao)想要(yao)(yao)(yao)有多(duo)個(ge)輸出力(li)和多(duo)個(ge)運動(dong)速度，就(jiu)需(xu)(xu)要(yao)(yao)(yao)多(duo)個(ge)減壓(ya)(ya)閥(fa)、節(jie)(jie)(jie)流(liu)(liu)閥(fa)及換向閥(fa)。這(zhe)樣，不僅元(yuan)件(jian)需(xu)(xu)要(yao)(yao)(yao)多(duo)，成(cheng)(cheng)本高，構(gou)成(cheng)(cheng)系統(tong)復雜，且許多(duo)元(yuan)件(jian)都需(xu)(xu)要(yao)(yao)(yao)預先進行人工調(diao)(diao)節(jie)(jie)(jie)。電氣(qi)比(bi)例閥(fa)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬于連續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，其特(te)點是輸出量(liang)(liang)隨輸入(ru)量(liang)(liang)的(de)變化(hua)而變化(hua)，輸出量(liang)(liang)與(yu)輸入(ru)量(liang)(liang)之(zhi)間(jian)存在(zai)一定的(de)比(bi)例關系。比(bi)例控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開(kai)環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)和閉環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)之(zhi)分。 |
