alt="上?；炝鞅弥圃焐?></div><p><strong>上?；炝鞅弥圃焐?/strong></p><p>潛水混流泵的結構特點(diǎn)自平衡系列大型潛水泵的電動(dòng)機結構主要分為兩種,一種是配礦、井用高壓潛水電泵的細長(cháng)型立式結構，主要是充水式;另一種是外徑尺寸不受限制的立式結構或臥式結構，電動(dòng)機可制作成干式、充水式或充油式幾種。ATZPQK型和ATSXQK型雙吸式大型潛水電泵的電動(dòng)機為充水密封式結構，與充水式井用潛水電動(dòng)機結構類(lèi)似。定子繞組采用聚氯乙烯絕緣高壓耐水絕緣導線(xiàn)或交聯(lián)聚乙烯絕緣尼龍護套高壓耐水絕緣導線(xiàn)制作，它們的Z高使用溫度分別為65℃和90℃。耐水絕緣導線(xiàn)相互間的連接及耐水絕緣異線(xiàn)與引出電纜之間的連接，采用丁基自黏性膠帶或性能接近的其他膠帶進(jìn)行包扎，作為耐水主絕緣層;外面再用機械強度較高的塑料膠粘帶或塑料帶進(jìn)行包扎，作為機械保護層。水潤滑導軸承由石墨浸漬金屬材料制作的軸瓦和鍍鉻軸套或不銹鋼淬硬軸套組成，軸瓦上的冷卻潤滑槽一般為螺旋槽。水潤滑止推軸承結構為分塊調心式，一般有16塊扇形軸瓦，每塊均可自動(dòng)調整，使軸承滑動(dòng)面形成楔形水膜。止推軸承材料為石墨浸漬金屬材料，配對材料為不銹鋼制作并淬硬的圓盤(pán)。上止推軸承結構為整體式。水泵有上、下兩個(gè)吸入口，兩組水泵葉輪對稱(chēng)分布，所產(chǎn)生的兩個(gè)軸向推力方向相反，正好相互平衡。這樣，電動(dòng)機下部的水潤滑止推軸承只需承受電動(dòng)機轉子和水泵轉動(dòng)部分的重量，而不需承受水泵運行時(shí)所產(chǎn)生的軸向水推力，止推軸承所承受的軸向載荷大大減小，軸承運行條件好轉，磨損量減小，壽命延長(cháng)，潛水電泵運行的總體可靠性也相應得到提高，使用壽命延長(cháng)。</p><div
