超級恒溫循環(huán)器與恒溫循環(huán)器的區(qū)別？答：主要在于恒溫的精度問題。一般來說，超級恒溫循環(huán)器熱電偶的精度更高，一般可以達到.1℃。有加熱和制冷兩種裝置的，這樣在恒溫的時候，效果會更好，一般都可以達到+/-.5℃。都是用來做恒溫要求比較高的試驗（物理化學居多），比如測粘度普通的恒溫循環(huán)器一般就是.1℃的精度了，甚至不是用熱電偶的，而是用觸點溫度計。為什么粘度計要垂直地置于恒溫循環(huán)器中?答：因為物質的粘度與其溫度成比例關系.另外,由于物質粘度的計算公式中有一個涉及剪切力的量,我想可能是因為這個原因才要直放的原因吧.因為如果剪切力相同而力的作用角度不同的話合成的剪切力也是不同的.請問恒溫循環(huán)器的恒溫原理是什么答：恒溫循環(huán)器控溫由下面幾部分組成：加熱部分：用電加熱管給恒溫循環(huán)器加熱測溫部分：一般用工業(yè)用鉑熱電阻作為測溫元件，將測得的溫度值轉換成相應的電阻信號給配套的顯示調節(jié)儀表顯示恒溫循環(huán)器內溫度調節(jié)控制部分：溫度顯示調節(jié)儀表根據測得的恒溫循環(huán)器內溫度與設定的溫度之差進行PID（比例、積分、微分）調節(jié)后控制可控硅導通角從而控制電加熱管的加熱功率，加熱功率隨溫差大小而改變，當達到設定溫度時，調節(jié)儀通過可控硅使加熱管產生的熱量與散失的熱量平衡，從而實現恒溫目的。
充水水泵在啟動以前，泵殼和吸水管內必須先充滿水，這是因為有空氣存在的情況下，泵吸人口真空無法形成和保持。暖泵輸送高溫液體的泵，如電廠的鍋爐給水泵，在啟動前必須先暖泵。這是因為給水泵在啟動時，高溫給水流過泵內，使泵體溫度從常溫很快升高到1～2℃，這會引起泵內外和各部件之間的溫差，若沒有足夠長的傳熱時間和適當控制溫升的措施，會使泵各處膨脹不均，造成泵體各部分變形、磨損、振動和軸承抱軸事故。
超聲波清洗設備的頻率應該在生產廠商所建議的范圍內，用經多次所得的佳頻率進行清洗。超聲波頻率越高，液體內氣泡的體積越小，強度也越弱，一般推薦使用的頻率為4KHz，在此頻率下，會產生小的氣泡深入網穴進行清洗.不過，由于網紋輥的性質及超聲波清洗設備設計不同，此頻率推薦值僅供參考。。清洗劑的溫度也會影響到清洗質量，溫度高，清洗劑黏度就低，液體中的氣泡量就會增加，從而增加超聲波清洗的能力。
b.雙吸泵葉輪的兩側同時吸入液體，如圖1-12所示。按導葉機構的形式a.蝸殼式泵具有像蝸牛殼形狀的離心泵，單級泵大多是這種形式。b.導葉式泵在葉輪外圍安有幾個固定導葉片的泵即為導葉式泵(圖1-13)。在早期，這種泵叫透平泵。多級泵大多是這種形式。按泵體接縫形式a.具有水平接縫的泵(中開式)通過泵軸中心線的水平面上開有泵體接縫的泵(圖1-12)。具有垂直接縫的泵垂直于泵軸中心線的面上安裝泵蓋的泵。
