SMC精裝軟啟動閥售價,全新SMC一級品質 
SMC軟啟動(dong)閥是可(ke)緩慢供(gong)(gong)氣(qi)，使氣(qi)動(dong)系統的初(chu)始(shi)壓力緩慢上升，并在切(qie)斷供(gong)(gong)氣(qi)后進(jin)行急速排氣(qi)的始(shi)動(dong)閥，消耗功率：0.35W，流(liu)量特性提高：zui大(da)2.3倍 C［dm3/ (s?bar) ］：9.2，節(jie)能：主閥切(qie)換時的氣(qi)流(liu)為零，低(di)速供(gong)(gong)氣(qi)時的調節(jie)靈(ling)敏度提高。

比(bi)如說電(dian)源(yuan)標(biao)準(zhun)輸出是(shi)12V   從0V到12V的上(shang)升(sheng)階段我們不希望升(sheng)的太快。因為(wei)如果電(dian)壓(ya)上(shang)升(sheng)過(guo)快   就會有很(hen)大(da)的沖擊(ji)電(dian)流(liu)以及(ji)其(qi)他危(wei)害。所以我們需要設(she)置電(dian)路(lu)讓電(dian)源(yuan)電(dian)壓(ya)緩緩地，平滑的上(shang)升(sheng)，這就是(shi)軟啟動(dong)。

SMC軟啟動閥原理:電源通過輸出電壓反饋值和設定的基準值來管控PWM信號，一般來說反饋和基準差距越大PWM越大上升越快。所以我們要想辦法在模塊電壓上升的時候盡可能減小反饋和基準的差距。
軟(ruan)啟動器的(de)工(gong)作原理 交流電(dian)機(ji)起動一般分為全壓(ya)起動、降(jiang)(jiang)壓(ya)起動和變(bian)頻起動。大(da)電(dian)機(ji)起動會產(chan)生超過10%的(de)線(xian)路電(dian)壓(ya)降(jiang)(jiang)，易引起其它電(dian)氣設備工(gong)作不(bu)正常，而且長時間的(de)5～8倍的(de)起動電(dian)流有可能造成變(bian)壓(ya)器過負荷(he)跳閘。

SMC軟啟動(dong)(dong)閥(fa)按照(zhao)規定(ding)，全壓(ya)(ya)(ya)(ya)起動(dong)(dong)的(de)鼠(shu)籠型電機(ji)的(de)容(rong)量(liang)(liang)不(bu)大(da)于(yu)變壓(ya)(ya)(ya)(ya)器容(rong)量(liang)(liang)的(de)20％～30%。因此(ci)，按全壓(ya)(ya)(ya)(ya)起動(dong)(dong)選擇變壓(ya)(ya)(ya)(ya)器容(rong)量(liang)(liang)，可能造成容(rong)量(liang)(liang)偏大(da)。100kW以上交流鼠(shu)籠式電機(ji)一般不(bu)允(yun)許采用(yong)全壓(ya)(ya)(ya)(ya)起動(dong)(dong)。變頻起動(dong)(dong)可以同時改變電壓(ya)(ya)(ya)(ya)和頻率，保持V/F不(bu)變。

SMC軟啟動(dong)(dong)(dong)(dong)(dong)閥(fa)傳(chuan)統(tong)上交流(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的起(qi)動(dong)(dong)(dong)(dong)(dong)采用(yong)降(jiang)壓(ya)起(qi)動(dong)(dong)(dong)(dong)(dong)，如自耦變壓(ya)器(qi)、星/三角起(qi)動(dong)(dong)(dong)(dong)(dong)器(qi)、串接(jie)起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)阻等，其原理是降(jiang)低電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)壓(ya)，減少對電(dian)(dian)(dian)(dian)(dian)網(wang)沖擊。這些(xie)傳(chuan)統(tong)的起(qi)動(dong)(dong)(dong)(dong)(dong)方(fang)法(fa)均存在(zai)一(yi)定(ding)的缺(que)陷：由(you)于存在(zai)主(zhu)回路(lu)電(dian)(dian)(dian)(dian)(dian)壓(ya)切換，會(hui)對電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)及機(ji)(ji)械設備(bei)產生沖擊，降(jiang)低設備(bei)使用(yong)壽(shou)命(ming)；主(zhu)回路(lu)耗能元件(jian)（如起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)阻）增加能耗，設備(bei)體積較大；降(jiang)低電(dian)(dian)(dian)(dian)(dian)壓(ya)的同時，起(qi)動(dong)(dong)(dong)(dong)(dong)力矩(ju)相應減少；一(yi)旦(dan)元器(qi)件(jian)選定(ding)后便(bian)無法(fa)調整起(qi)動(dong)(dong)(dong)(dong)(dong)力矩(ju)。一(yi)種(zhong)采用(yong)微處理器(qi)控制的由(you)晶閘管元件(jian)組成的“軟起(qi)動(dong)(dong)(dong)(dong)(dong)器(qi)”能很好地克服上述(shu)缺(que)點。

SMC軟(ruan)啟動(dong)閥是一種用m*電(dian)(dian)(dian)流(liu)控(kong)制達幾kA晶閘(zha)(zha)管(guan)的(de)(de)無觸點電(dian)(dian)(dian)力(li)控(kong)制設(she)備。它以(yi)微(wei)處(chu)理器為核心，輔(fu)加相應檢測電(dian)(dian)(dian)路，通過(guo)改變晶閘(zha)(zha)管(guan)觸發導通角(jiao)，產(chan)生平滑的(de)(de)電(dian)(dian)(dian)壓起(qi)動(dong)曲線(xian)；通過(guo)對起(qi)動(dong)電(dian)(dian)(dian)流(liu)閉環控(kong)制，任(ren)意設(she)置(zhi)穩定的(de)(de)起(qi)動(dong)電(dian)(dian)(dian)流(liu)。這種基于(yu)微(wei)處(chu)理器基礎上(shang)的(de)(de)軟(ruan)件化控(kong)制，不僅有(you)一般(ban)的(de)(de)電(dian)(dian)(dian)機保護功(gong)能，還有(you)雙(shuang)斜坡(po)啟動(dong)和預置(zhi)低(di)速運行(xing)、避(bi)免機械沖(chong)擊等特殊(shu)的(de)(de)工藝控(kong)制功(gong)能，其控(kong)制原理見圖1。

SMC軟起(qi)動(dong)器(qi)系列有多種類型，其(qi)中RSS1DH軟起(qi)動(dong)器(qi)的額定輸入電壓為(wei)380～415V，頻率50Hz，內置風扇，工作溫度(du)55℃，裝入柜內自然(ran)通(tong)風即可。軟起(qi)動(dong)器(qi)控(kong)制面(mian)板有手動(dong)設(she)定電位器(qi)、運行和故(gu)障指示燈(deng)及選擇開關等。
