Relationship between pump head and flow? How to calculate the lift? Pure water equipment ultra pure water equipment manufacturer
泵的揚程計算是選擇泵的重要依據(jù),泵揚程與流量的關(guān)系可以參照下面這張圖。
泵揚程由管網(wǎng)系統(tǒng)的安裝和操作條件決定,計算前應(yīng)首先繪制流程草圖,平、立面布置圖,計算出管線的長度、管徑及管件型式和數(shù)量。
一般管網(wǎng)如下圖所示
D——排出幾何高度,m;
取值:高于泵入口中心線:為正;低于泵入口中心線:為負(fù);
S——吸入幾何高度,m;
取值:高于泵入口中心線:為負(fù);低于泵入口中心線:為正;
Pd、Ps——容器內(nèi)操作壓力,m液柱(表壓);
取值:以表壓正負(fù)為準(zhǔn)
Hf1——直管阻...

[knowledge] coagulation? Flocculation? Coagulation aid? Silly can't tell? A text to take you to understand Pure water equipment, ultrapure water equipment
混凝?絮凝?助凝?
在水處理藥劑中,應(yīng)用最廣泛的是當(dāng)屬混凝與絮凝、聚合氯化鋁與聚丙烯酰胺了。那么兩者在使用過程中具體有哪些注意事項?讓我們一來一探究竟。
凝聚:投加混凝劑后水中的膠體失去穩(wěn)定性,膠體顆?;ハ嗄?,結(jié)果形成眾多的“小礬花”。
絮凝:凝聚過程中形成的“小礬花”通過吸附、卷帶、架橋等作用,形成顆粒較大絮凝體的過程。
混凝:是凝聚、絮凝兩個過程的總稱。是水中膠體粒子及微小懸浮物的聚集過程。
也就是說,“混凝”包含了從原水投藥到水混合、藥反應(yīng)(脫穩(wěn)、絮凝)再到形成大顆粒的絮凝物的整個過程。
而絮凝是指膠體...
