单级乳化泵与多乳化心泵有何区别

发布时间:2017/7/28 9:41:00

　在泵行业中，现在很多人弄不清楚单级泵与多级泵有什么区别，怎么去分辨一直是个头痛的问题，现在就告诉你们怎么去分辨和了解单级泵和多级泵了。

       一、单级泵与多级泵定义上的区别：

　　单级泵是指只有一只叶轮的泵，一般的单级泵最高扬程只有125米，具有结构简单，性能平稳，转速高，体积小，重量轻，效率高，流量大，容易操作和维修等优特点。

　　多级泵是很多单级泵的简单串联，组合在一起。他的输出水压可以很大。是离心泵的一种，也是依靠叶轮的旋转在获取离心力，从而物料。待气体密度达到机械真空泵的工作范围而被抽出，从而逐渐获得高真空。多级泵是靠泵腔容积的变化来实现吸气、压缩和排气的，因此它是可以变容积的离心泵。

　　二、单级泵与多级泵结构上的特点区分：

　　单级泵包括泵体，泵盖，带输出轴的电动机，在单级泵体内装设的泵轴、轴承座、叶轮、机械密封和机封压盖，其特征在于，它还包括位于电动机输出轴与泵轴之间设置的对夹式联轴器，以及安装在轴承座上的以辅助支承泵轴的导轴承;所述对夹式联轴器分别与电动机输出轴和泵轴刚性连接，在电动机输出轴与泵轴之间留有便于机械密封和机封压盖装拆的空间距离。在维修或更换机械密封时，无须拆卸电动机及泵盖。

　　多级泵的基本构造是由六部分组成的分别是叶轮，泵体，泵轴，轴承，密封环，填料函。具体多级泵上面叶轮，泵体，泵轴，轴承，密封环，填料函有怎么样特点，欢迎联系我们公司业务人员进行详细了解了。

　　然而、随着技术的进步，单级叶轮的泵可通过提高泵的转速来提高泵的扬程，可代替多级泵，只是价格贵一点。

In the pump industry, many people now do not know what is the difference between single-stage pump and multi-stage pump, how to distinguish has been a headache problem, now tell you how to distinguish and understand the single-stage pump and multi-stage pump.

       First, single-stage pump and multi-stage pump on the definition of the difference:

Single-stage pump is only one impeller pump, the general single-stage pump only 125 meters maximum head, with a simple structure, smooth performance, high speed, small size, light weight, high efficiency, large flow, easy operation and maintenance Excellent features.

Multi-stage pump is a simple single-stage pump in series, combined together. His output water pressure can be great. Is a kind of centrifugal pump, but also rely on the rotation of the impeller in the centrifugal force to obtain the material. Until the gas density to reach the working range of mechanical vacuum pump was pulled out, and thus gradually get high vacuum. Multi-stage pump is the pump chamber volume changes to achieve inspiration, compression and exhaust, so it can be variable volume centrifugal pump.

Second, the single-stage pump and multi-stage pump on the characteristics of the distinction:

The single stage pump includes a pump body, a pump cover, an electric motor with an output shaft, a pump shaft, a bearing seat, an impeller, a mechanical seal and a machine gland installed in the single stage pump body, characterized in that it further comprises a motor A pinch coupling provided between the shaft and the shaft, and a guide bearing mounted on the bearing seat to assist the support shaft, the pair of clamp couplers being rigidly connected to the motor output shaft and the pump shaft, respectively, Between the motor output shaft and the pump shaft, there is a space distance between the mechanical seal and the mechanical gland. There is no need to remove the motor and pump cover when servicing or replacing mechanical seals.

The basic structure of the multi-stage pump is composed of six parts are impeller, pump, pump shaft, bearing, seal ring, stuffing box. Specific multi-stage pump above the impeller, pump, pump shaft, bearings, seal ring, stuffing box how the characteristics, please contact our business staff to understand in detail.

However, with the advancement of technology, single-stage impeller pump can improve pump speed by increasing pump speed, instead of multi-stage pump, but the price is more expensive.
