為了解決這個難題,必須提高硫的轉化率。這一方面需要較高的燃燒溫度,同時還需要保持較長的高溫持續(xù)時間。這是因為硫的轉化率與溫度有密切關系,燃燒溫度12~14℃時,硫的轉化率為61~83%;溫度為145~151℃時,硫的轉化率為98%。溫度高,對硫的轉化有力。另外,由于硫化物熔點高,燃燒反應困難,因此必須有足夠的高溫持續(xù)時間以保證硫的燃燒反應進行完全。初期的電弧爐在燃燒時的不足之處是難以滿足測定硫對燃燒條件的這種要求。

CV1500-200-S-G3-TR-V3 在設計一個新的機械設備時,首先需要考慮選擇什么樣的步進電機較為適合,步進電機選型方面有什么技巧呢? 1、確定步進電機機械傳動結構 傳動結構包括直接連接、絲桿傳動、皮帶傳動等等。這時要考慮到一些對步進電機機械上的要求,比如大概可接受尺寸、安裝 要求、電機徑向、軸向受力及竄動要求等等。 2、確定需要的分辨率 根據(jù)選定的機械結構和整機要求,確定電機的分辨率,即步距角,例如要選用 0.9°或是 1.8°的電機。 3、根據(jù)機械傳動要求,確定運轉模式 也即根據(jù)機械移動,定位和時間要求來確定步進電機運轉的速度,角度和加減速曲線。 3.1 計算運轉脈沖數(shù) 脈沖數(shù) =(要求的位移量/電機轉一圈的位移量)*(360°/步距角) 3.2 確定運行曲線和計算脈沖頻率 一般來說運行曲線使用矩形和梯形兩種。 ☆矩形曲線 電機直接以運行頻率啟動,運轉到位后直接停止。這種運轉方式需要非常大的加速扭矩。 ☆梯形曲線 電機由較低的頻率啟動,加速到要求速度,運行一定時間后要求再減速然后停止。這樣速度變化較為緩慢,對加 速扭矩要求可適當降低。通常加減速度時間設定為定位時間的 25% 左右。根據(jù)實際情況確定啟動頻率,啟動時間(也 可以考慮在多少個脈沖數(shù)后加速到運行頻率)。 |
