意大利ATOS比例閥特點: - 可實現壓力(li)、速(su)度的無極調節,避免(mian)了常(chang)通的開關式氣閥換向時的沖擊現象。
- 能實(shi)現遠(yuan)程(cheng)控制和程(cheng)序控制。
- 與斷續控制相比,系統簡(jian)化,元(yuan)件(jian)大大減(jian)少。
- 與液壓比例閥相比,體積小(xiao)、重(zhong)量輕、結構簡單、成本較低,但響應(ying)速(su)度(du)比液壓系統(tong)慢得多,對負載變化也(ye)比較敏感。
- 使用功率小、發熱少、噪聲低(di)。
- 不會發生火災(zai),*。受溫度變化的(de)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)(qi)(qi)比例閥(fa)(fa)(fa)自動控(kong)(kong)(kong)制(zhi)(zhi)可分成(cheng)斷續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)和(he)連(lian)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)。斷續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)即開關(guan)控(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)(qi)(qi)動控(kong)(kong)(kong)制(zhi)(zhi)系(xi)統中(zhong)使用(yong)動作頻率較低(di)的(de)開關(guan)式(ON-OFF)的(de)換向(xiang)閥(fa)(fa)(fa)來(lai)(lai)控(kong)(kong)(kong)制(zhi)(zhi)氣(qi)(qi)(qi)路的(de)通斷。靠減壓閥(fa)(fa)(fa)來(lai)(lai)調(diao)節(jie)所需(xu)要(yao)(yao)的(de)壓力,靠節(jie)流閥(fa)(fa)(fa)來(lai)(lai)調(diao)節(jie)所需(xu)要(yao)(yao)的(de)流量。這種傳統的(de)氣(qi)(qi)(qi)動控(kong)(kong)(kong)制(zhi)(zhi)系(xi)統要(yao)(yao)想要(yao)(yao)有(you)多個(ge)(ge)輸出力和(he)多個(ge)(ge)運動速度,就需(xu)要(yao)(yao)多個(ge)(ge)減壓閥(fa)(fa)(fa)、節(jie)流閥(fa)(fa)(fa)及(ji)換向(xiang)閥(fa)(fa)(fa)。這樣,不(bu)僅元件(jian)需(xu)要(yao)(yao)多,成(cheng)本高,構成(cheng)系(xi)統復雜,且許多元件(jian)都需(xu)要(yao)(yao)預先進行人(ren)工(gong)調(diao)節(jie)。電氣(qi)(qi)(qi)比例閥(fa)(fa)(fa)控(kong)(kong)(kong)制(zhi)(zhi)屬于連(lian)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi),其(qi)特點是輸出量隨(sui)輸入(ru)(ru)量的(de)變化而變化,輸出量與(yu)輸入(ru)(ru)量之間(jian)存在一(yi)定的(de)比例關(guan)系(xi)。比例控(kong)(kong)(kong)制(zhi)(zhi)有(you)開環(huan)(huan)控(kong)(kong)(kong)制(zhi)(zhi)和(he)閉環(huan)(huan)控(kong)(kong)(kong)制(zhi)(zhi)之分。 |
