雙級回收小型噴霧干燥機采用雙極旋風分離回收系統，大大提高了產品的回收率。二流體噴霧的霧化結構，整機采用優質不銹鋼材料精密制造，設計緊湊，無需附屬設備，方便使用，歷久如新。為了滿足用戶在實驗范圍調節各項參數的要求，在干燥溫度控制的設計上采用實時調控PID恒溫控制技術，使全溫區控溫準確，加熱控溫精度±1℃。
電(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)路工作時都需要直流(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)提供能量，電(dian)(dian)(dian)池因使(shi)用費用高，一般(ban)只用于(yu)低功耗(hao)便攜式的儀(yi)器設(she)備(bei)中，大(da)部分電(dian)(dian)(dian)子(zi)(zi)儀(yi)器設(she)備(bei)、家用電(dian)(dian)(dian)器、計(ji)算機(ji)都需要把交流(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)變(bian)換為直流(liu)(liu)穩壓電(dian)(dian)(dian)源(yuan)(yuan)。

引起輸(shu)出電壓(ya)變(bian)化的(de)(de)原因(yin)是負(fu)載電流的(de)(de)變(bian)化和輸(shu)入電壓(ya)的(de)(de)變(bian)化，負(fu)載電流的(de)(de)變(bian)化會在(zai)整流電源(yuan)的(de)(de)內阻上產生電壓(ya)降，從而(er)使輸(shu)入電壓(ya)發(fa)生變(bian)化。硅穩壓(ya)二極管(guan)穩壓(ya)電路(lu)(lu)的(de)(de)電路(lu)(lu)。它是利用穩壓(ya)二極管(guan)的(de)(de)反(fan)向擊穿特性穩壓(ya)的(de)(de)，由(you)于反(fan)向特性陡直，較(jiao)大的(de)(de)電流變(bian)化，只會引起較(jiao)小的(de)(de)電壓(ya)變(bian)化。
