通常需求在吸水管進(jìn)口裝設(shè)底閥,以滿意發(fā)動(dòng)灌水的需求.底噢的水力丟失比較大,會(huì)添加水泵的實(shí)際工作揚(yáng)程,加大電能的耗費(fèi).一起,底閥還容易發(fā)生被卡住的現(xiàn)象.我縣在混流泵的使用中,采用了以S形保水管自吸真空來(lái)代替底閥灌水的新方法.經(jīng)長(zhǎng)期實(shí)踐,作用良好,現(xiàn)介紹如下. 圖1為14HB一40型混流泵無(wú)底閥自吸真空的裝置示意圖.在進(jìn)水管上用兩個(gè)或三個(gè)彎管構(gòu)成S形,構(gòu)成一段虹吸管.虹吸管底部應(yīng)高于泵輪。?混流泵無(wú)底閥自吸真空的應(yīng)用。當(dāng)水泵的裝置高程高于進(jìn)水池水位時(shí)使水泵中能堅(jiān)持有水.首次發(fā)動(dòng)時(shí)。
一.概述
1.用途：HW混流泵為臥式，單級(jí)，單吸，渦殼式混流泵。適用于輸送清水或物理，化學(xué)性質(zhì)類(lèi)似于水的其它液體。被輸送液體溫度不宜高于50度。廣泛用于農(nóng)田灌溉，工業(yè)和城市排水等多種場(chǎng)合。HW泵的性能范圍：流量90-9000m3/h 揚(yáng)程3.5-22m。
2. 特點(diǎn)：結(jié)構(gòu)簡(jiǎn)單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan5.15
3. 傳動(dòng)方式：用直接傳動(dòng)和變速傳動(dòng)。常用動(dòng)力機(jī)是電動(dòng)機(jī)和柴油機(jī)。訂貨 時(shí)應(yīng)明確動(dòng)力機(jī)的型號(hào)，以便確定聯(lián)軸器和皮帶輪的型號(hào)

電氣設(shè)備是混流泵的重要組成部分，做好泵的安全和良好運(yùn)行，進(jìn)行定期的維護(hù)和管理，有必要對(duì)電氣設(shè)備有全面的了解，不僅要了解其性能，還要注意經(jīng)常發(fā)生事故的原因，分析每一個(gè)故障原因與解決方案。
二.結(jié)構(gòu)和作用
1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water.
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different perbance of the impeller.

減小摩擦損失對(duì)于前兩項(xiàng)而言，若是零件表面粗糙度大，可進(jìn)行先磨光后涂護(hù)，涂護(hù)按面積大小采用環(huán)氧樹(shù)脂等易涂、耐磨材料做涂敷處理；若因汽蝕原因造成流道表面局部損傷，應(yīng)先除銹再涂護(hù)，面積小時(shí)，可進(jìn)行焊補(bǔ)、磨光處理。至于第三項(xiàng)，混流泵內(nèi)部各轉(zhuǎn)動(dòng)部件配合面關(guān)鍵是嚴(yán)把配件的加工質(zhì)量關(guān)和裝配質(zhì)量關(guān)，確保有理想的水流流態(tài)，以降低混流泵內(nèi)部的摩擦損失。
