汙泥回流偏心螺杆泵,汙泥擠壓泵,汙泥進料螺杆泵選型參數
時間:2013/3/30 來源(yuán):浙(zhè)江香蕉视频网站江泵業有限公司
G型單螺杆泵因橡膠桶選(xuǎn)用多種彈性材料製成,所(suǒ)以這種(zhǒng)G型單螺杆泵可以輸送粘度達到80%流體的輸送和含有硬質懸(xuán)浮顆粒介質或含有纖維介質的輸送,有一般泵種所不能勝任的特性。其流量與(yǔ)轉速成正比,G型單螺杆泵(bèng)結構緊湊,體(tǐ)積小,維修簡(jiǎn)便。對(duì)介質的適應性(xìng)強,流量平穩,壓力脈動(dòng)小,自吸能力高。工作溫度可達120℃,如果需輸送120℃-350℃高溫介質,可定做。廣泛用於食品、冶金(jīn)、造紙、印染、化工(gōng)、化肥、製藥等工業部(bù)門。

2、各類(lèi)含磨蝕(shí)性物料介質舉例:
A、無磨蝕介質:淡水、油、漿汁、甘油、血液、肥皂水等;
B、輕磨蝕(shí)介(jiè)質:軟(ruǎn)質泥(ní)漿(jiāng),含水95%以上(shàng)的汙泥,如活性汙泥水,精糖廢液,農畜屎尿,工(gōng)業廢等;
C、中等磨蝕介質:含有固體物料的泥漿,含水85%以上的泥漿,如塗料(liào),糖蜜,研削液,石膏泥漿等;
D、嚴重(chóng)磨蝕介質:水煤(méi)漿,含有磨蝕性物質的漿液(yè),含水率50%以上的汙泥,如研(yán)磨液,溫泉泥,PVC漿料
,粘土,脫水占結劑等。
D、輸送(sòng)介質的粘度也是選(xuǎn)泵需要的一個因素,泵的運行(háng)轉速隨著介質的粘度而降低,若(ruò)粘度達(dá)到150000
mpa以上時,一般結構的泵無法吸入,則必須增設喂料器等特殊(shū)設計。
六 按泵輸(shū)送(sòng)介質粘度的合適轉速(粘度(dù)單(dān)位:mpa.s)
