渣浆泵叶片式泵的分类
叶片式泵按其结构型式，分类如下:

1.按液体流出叶轮的方向

(1) 离心式:轴向吸入，径向流出，如图2-9所示;

(2) 轴流式:轴向吸入，轴向流出，如图2-10所示;

(3) 混流式:轴向吸入，斜向流出，如图2-11所示。

2.按液体吸入方式

(1)单吸:液体从叶轮的一侧吸入，如图2-9所示;

(2)双吸:液体从叶轮的两侧吸入，如图2-12所示。

3.技叶轮数目

(1)单级:泵内只有一个叶轮的泵;

(2)两级:泵内有二个叶轮串联的泵;

(3)多级:泵内有二个或二个以上叶轮串联的泵，泵内叶轮个数称为多级泵的级数。

4.按叶片安装方法可否转动

(1)可调叶片:叶片安装角可转动调节的，即转叶式，它只用在混流式和轴流式中;

(2)固定叶片:叶片安放角是固定的，即旋桨式。

5.按泵体形式

(1) 蜗壳式:压水室为螺旋形蜗室的壳体;

(2) 双蜗壳式:压水室为二个蜗室的壳体;

(3)透平泵:带导叶的压水室;

(4)筒式泵:内壳体外装有圆筒状的耐压壳体;

(5)双壳泵:双层壳体泵。 渣浆泵厂家

Classification of vane pumps for slurry pumps

The vane pump is classified as follows according to its structural type:

1. According to the direction of liquid flowing out of impeller

(1) centrifugal: axial suction, radial outflow, as shown in Figure 2-9;

(2) axial flow type: axial suction, axial outflow, as shown in Figure 2-10;

(3) mixed flow type: axial suction, oblique outflow, as shown in Figure 2-11.

2. According to the way of liquid inhalation

(1) single suction: liquid is inhaled from one side of impeller, as shown in Figure 2-9;

(2) double suction: liquid is inhaled from both sides of the impeller, as shown in Figure 2-12.

3. Number of technical impellers

(1) single stage: a pump with only one impeller;

(2) two stages: the pump has two impellers in series;

(3) multistage: a pump with two or more impellers in series in the pump. The number of impellers in the pump is called the stage of multistage pump.

4. Can the blade be rotated according to the installation method

(1) adjustable blade: the installation angle of the blade can be adjusted by turning, that is, the rotating blade type, which is only used in the mixed flow type and axial flow type;

(2) fixed blade: the blade angle is fixed, i.e. propeller type.

5. According to the pump body form

(1) volute type: the pressurized water chamber is the shell of spiral volute chamber;

(2) double volute type: the pressurized water chamber is the shell of two volutes;

(3) turbine pump: pressure chamber with guide vane;

(4) barrel pump: the inner casing is equipped with cylindrical pressure housing outside;

(5) double shell pump: double shell pump Slurry pump manufacturer
