以满意构造紧凑的请求，如图1所示。径导游叶的正导叶是由螺旋线有些以及螺旋线后边的分散管有些组成。其用途分别为:内螺旋线有些，用来保证液体在导叶中的自在活动，起搜集液体的效果，而分散有些用来把大有些动能变换为压力能，起变换动能为压力能的效果。2径向正导叶的水力规划本文所讨论的是图1中的径向正导叶的水力规划。2.1规划原则径向正导叶混流泵叶轮图1模型水力构造图导叶内液体的轴对称活动。

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

混流泵是一种“拉出”式结构泵，在检查和拆卸叶轮和轴封时，毋须将与泵体相连接的管路拆开。装有精密加工的泵轴和装有稀油润滑的轴承，在填料函盖中装有防护轴套。轴承箱的油位，可由恒位油杯来控制。

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.
Water pump, valve and accessories technology R & amp; d and Sales: motor, bearings, mechanical seals, metal Products Sales: Pump assembly and maintenance: self-and with all kinds of goods and technology import and export business (except for goods and technologies that the state limits the company to operate or prohibit imports and exports).
