（2）安裝面積小 包含驅(qū)動機在內(nèi)，立式泵只需臥式泵的一半空間就滿足了。特別是在泵大型化的今日，這個長處愈加杰出。
一.概述
1.用途：HW混流泵為臥式，單級，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合。HW泵的性能范圍：流量90-9000m3/h 揚程3.5-22m。
2. 特點：結(jié)構(gòu)簡單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan6.22
3. 傳動方式：用直接傳動和變速傳動。常用動力機是電動機和柴油機。訂貨 時應(yīng)明確動力機的型號，以便確定聯(lián)軸器和皮帶輪的型號
4.型號說明：以150HW-8S例
150---------泵進出口直徑mm
8------------設(shè)計揚程 m
S------------變型代號

混流泵工作原理從工作原理來說，當原動機帶動葉輪旋轉(zhuǎn)后，對液體的作用既有離心力又有軸向推力，是離心泵和軸流泵的綜合。因此它是介于離心泵和軸流泵之間的一種泵。混流泵的比轉(zhuǎn)速高于離心泵，低于軸流泵，一般在300-500之間。它的揚程比軸流泵高，但比離心泵低流量比軸流泵小，比離心泵大?；炝鞅弥饕糜谵r(nóng)業(yè)排灌，另外還用于城市排水，可作為熱電站循環(huán)水泵之用。主要在泵體內(nèi)，設(shè)有幾個通常為扭曲葉片式空間導(dǎo)葉裝置。液體從葉輪出來經(jīng)過導(dǎo)葉后便沿軸向流動。泵體外形為圓筒，但看上去像鼓著大肚子，有點像軸流泵。這種泵一般有臥式和立式兩種，內(nèi)部結(jié)構(gòu)基本相同。大口徑的大多做成立式的。小口徑立式導(dǎo)葉式混流泵外形很像離心式淺井泵。
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.

混流泵是介于離心泵和軸流泵之間的泵型需要把壓水室規(guī)劃成徑導(dǎo)游葉(正導(dǎo)葉)加上類球形泵殼的構(gòu)造型式是葉輪內(nèi)安穩(wěn)的相對運動的條件。為此，請求在導(dǎo)葉中的螺旋線有些的液體，不受任何外力的效果。
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.
