混流泵

混流泵，英文为：Mixed flow pump

当原动机带动叶轮旋转后，对液体的作用既有离心力又有轴向推力，是离心泵和轴流泵的综合，液体斜向流出叶轮。因此它是介于离心泵和轴流泵之间的一种泵。Sealingequipmentiscomposedofstuffingbox,waterseal,packinggland,leadpowder(oroilimmersed)asbestospackingpadding。混流泵的比转速高于离心泵，低于轴流泵，一般在300-500之间。它的扬程比轴流泵高，但流量比轴流泵小，比离心泵大。3应用范围编辑用于输送清洁和污染的介质，化学中性或侵蚀性的介质。

化工流程中强制循环、海水养殖、城市煤气工程、水处理系统。

（一） 型号说明：

以250HW-8为例：

250—泵进（出）水口直径为250毫米。

8—泵总扬程为8米。

III. Type Instruction:

Take 250HW-8 for an example:

250-The diameter of inlet /outlet of pump is 250mm.

8-The total head of pump is 8m.

2、水泵起动后有一股水就不出水了

After starting ,

the pump only send one stream water then no water runs out

1、吸入的水中有过多气泡

2、吸水管中窝存空气

3、吸水管或连接处垫料不严密有进气现象

4、底阀或叶轮有水草杂物填塞

1.There are too many bubbles in the

indrawn water

2.There is air in the suction pipes

3.The paddings in connected parts are

imprecision and produces leaking phenomenon

4.There are waterweeds and sundries

filled in the bottom valve or impeller

1、检查进水管末端是否在水平面以下一米左右

2、排除空气

3、高速垫料，填塞缝隙拧紧螺栓

4、消除水草杂物

1.Check the end

of water inlet pipe if it is under the water surface at one meter

2. Remove the

air

3.Add padding to

fill the gaps and then tighten the bolts

4.Clear the

waterweeds and sundries.

6、轴承发热

The bearing is

hot

1、润滑油脂不足

2、润滑油质量不好或不清洁

3、轴心没有对准

4、轴承松动或磨损

5、皮带太紧

1.Lubricating grease is not enough

2.The quality of lubricating oil is not

good or dirty

3.The axes is not aiming

4.The bearing is loose or attrition

5.The belt is too tight.

1、加油

2、清洗轴承

3、找正

4、修正

5、适当放松

1.Add lubrication oil

2.Wash

the bearing

3.Aligning

4.Amending

5.Loosen it properly
