（3）有利于防止汽蚀 立式泵的叶轮一般沉没在水中，可以使用的NPSH可以取的大一些。因而，泵运转在比规划点大的流量也不会发作汽蚀。

一.概述

1.用途：HW混流泵为卧式，单级，单吸，涡壳式混流泵。适用于输送清水或物理，化学性质类似于水的其它液体。被输送液体温度不宜高于50度。广泛用于农田灌溉，工业和城市排水等多种场合。HW泵的性能范围：流量90-9000m3/h    扬程3.5-22m。

2. 特点：结构简单，使用可靠，装修方便，而且效率高，体型小，重量轻。jdhuiquan5.15

3. 传动方式：用直接传动和变速传动。常用动力机是电动机和柴油机。订货   时应明确动力机的型号，以便确定联轴器和皮带轮的型号

4.型号说明：以150HW-8S例

         150---------泵进出口直径mm

1，原动机或电源不正常。处理办法：查看电源和原动机状况。2，泵卡住。处理办法：用手盘动联轴器查看，必要时崩溃查看，消除动静有些毛病。3，填料压得太紧。处理办法：放松填料。4，排出阀未关。处理办法：封闭排出阀，从头发动

二.结构和作用

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.
