1）運(yùn)轉(zhuǎn)操作簡略 臥式泵，由于葉輪都在水面以上，在泵發(fā)動之前，要用真空泵向泵內(nèi)灌水，由于立式泵的葉輪，一般沉沒在水中，可以直接發(fā)動。

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(yáng)程3.5-22m。

2. 特點(diǎn)：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。jdhuiquan5.15

3. 傳動方式：用直接傳動和變速傳動。常用動力機(jī)是電動機(jī)和柴油機(jī)。訂貨   時應(yīng)明確動力機(jī)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

1，同2，3。處理辦法：采納相應(yīng)措施。2，體系靜揚(yáng)程添加。處理辦法：查看液體高度和體系壓力。3，阻力丟失添加。處理辦法：查看管路及止逆閥等障礙。4，殼體和葉輪耐磨環(huán)磨損過大。處理辦法：替換或修補(bǔ)耐磨環(huán)及葉輪。

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 performance of the impeller.

（3）有利于防止汽蝕 立式泵的葉輪一般沉沒在水中，可以使用的NPSH可以取的大一些。因而，泵運(yùn)轉(zhuǎn)在比規(guī)劃點(diǎn)大的流量也不會發(fā)作汽蝕。
