意大利ATOS比例閥特點: - 可實現(xian)壓(ya)力(li)、速度的(de)無(wu)極調節,避免了常通的(de)開關式(shi)氣(qi)閥換向時的(de)沖(chong)擊現(xian)象。
- 能(neng)實現(xian)遠程控(kong)制(zhi)和程序控(kong)制(zhi)。
- 與(yu)斷續控制相比,系(xi)統簡化,元(yuan)件(jian)大大減少。
- 與液壓比(bi)例閥相比(bi),體(ti)積小、重量(liang)輕、結構簡單、成本較低,但(dan)響(xiang)應速度比(bi)液壓系統慢(man)得(de)多,對負載變(bian)化也比(bi)較敏感(gan)。
- 使用功(gong)率(lv)小、發熱少(shao)、噪聲(sheng)低。
- 不(bu)會發(fa)生(sheng)火(huo)災,*。受溫度變化的影(ying)響小。

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)自動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)可分(fen)(fen)成斷(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)和(he)連(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)。斷(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)即開關控(kong)(kong)制(zhi)(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)中使用(yong)動(dong)作頻率(lv)較低的開關式(shi)(ON-OFF)的換向(xiang)閥(fa)來(lai)控(kong)(kong)制(zhi)(zhi)(zhi)氣(qi)路的通斷(duan)。靠減壓閥(fa)來(lai)調節(jie)所(suo)需要(yao)(yao)的壓力,靠節(jie)流(liu)閥(fa)來(lai)調節(jie)所(suo)需要(yao)(yao)的流(liu)量。這種傳(chuan)統(tong)的氣(qi)動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)要(yao)(yao)想要(yao)(yao)有(you)多(duo)(duo)個(ge)輸出力和(he)多(duo)(duo)個(ge)運(yun)動(dong)速度,就需要(yao)(yao)多(duo)(duo)個(ge)減壓閥(fa)、節(jie)流(liu)閥(fa)及換向(xiang)閥(fa)。這樣,不僅元(yuan)件(jian)需要(yao)(yao)多(duo)(duo),成本高,構成系統(tong)復雜,且許(xu)多(duo)(duo)元(yuan)件(jian)都需要(yao)(yao)預先進行人工調節(jie)。電氣(qi)比例(li)閥(fa)控(kong)(kong)制(zhi)(zhi)(zhi)屬于連(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi),其(qi)特點是(shi)輸出量隨(sui)輸入量的變化而變化,輸出量與輸入量之間存在一定的比例(li)關系。比例(li)控(kong)(kong)制(zhi)(zhi)(zhi)有(you)開環(huan)控(kong)(kong)制(zhi)(zhi)(zhi)和(he)閉(bi)環(huan)控(kong)(kong)制(zhi)(zhi)(zhi)之分(fen)(fen)。 |
