管道泵各个零部件的介绍

1、电机: 将电能转化为机械能的主要部件。

2、泵座:是泵的主体,起到支撑固定作用。

3、叶轮:离心泵的中心局部,它转速高、出力大,叶轮上的叶片又起到主要作用,叶轮在装配前要经过静均衡实验。叶轮上的内表面面请求润滑,以减少水流的摩擦损失。叶轮的分类开式叶轮:适用于保送含有较大量悬浮物的物料,效率较低,保送的液体压力不高。半闭式叶轮:适用于保送易沉淀或含有含有固体颗粒、纤维等悬浮物颗粒的物料,效率也较低。闭式叶轮:适用于保送不含杂质的清洁液体 ,效率高。

4、泵轴:电动机相衔接,它是传送机械能的主要部件。

5、机械密封:坚持贴兼并相对滑动而构成的避免流体走漏的安装

1. Motor: the main part that converts electric energy into mechanical energy.

2. Pump seat: it is the main body of the pump and plays a supporting and fixing role.

3. Impeller: the central part of the centrifugal pump, which has high speed and large output, and the blades on the impeller play a major role. The impeller shall undergo static equilibrium test before assembly. The inner surface of impeller requires lubrication to reduce the friction loss of water flow.

Classification of impellers

Ope mpeller: it is suitable for conveying materials containing a large amount of suspended solids, with low efficiency and low liquid pressure.

Semi closed impeller: suitable for conveying materials that are easy to precipitate or contain suspended particles such as solid particles and fibers, with low efficiency.

Closed impeller: suitable for delivering clean liquid without impurities, high efficiency.

4. Pump shaft: the motor is connected, which is the main part of mechanical energy transmission.

5. Mechanical seal: installation to avoid leakage of fluid formed by sticking and merging relative sliding
