潜水排污泵是一种泵与电机连体，并同时潜入液下工作的泵类产品，与一般卧式泵或立式污水泵相比，潜水排污泵明显具有以下几个方面的优点：

Submersible sewage pump is a pump and motor Siamese, and at the same time into the work under the liquid pump products, compared with general horizontal or vertical sewage pump, submersible sewage pump has obvious advantages of the following aspects:

1.结构紧凑、占地面积小。潜水排污泵由于潜入液下工作，因此可直接安装于污水池内，无需建造专门的泵房用来安装泵及机，可以节省大量的土地及基建费用。

1. Compact structure, cover an area of an area small. Diving sewage pump due to dive under the working fluid, and therefore can be directly installed in the sewage pool, to build a special pump used to install pumps and machines, can save a lot of land and infrastructure costs.

2.安装维修方便。小型的潜水排污泵可以自由安装，大型的潜水排污泵一般都配有自动藕合装置可以进行自动安装，安装及维修相当方便。

2. Easy installation and maintenance. Small diving sewage pump free installation, large diving sewage pump is generally equipped with automatic coupling device can be installed automatically, installation and maintenance is very convenient.

3.连续运转时间长。潜水排污泵由于泵和电机同轴，轴短，转动部件重量轻，因此轴承上承受的载荷径向相对较小，寿命比一般泵要长得多。

3. Continuous operation time is long. Diving sewage pump due to the pump and motor coaxial, shaft short, rotating parts weight is light, so carry the load on bearing radial is relatively small, life is much longer than the average pump.

4.不存在汽蚀破坏及灌引水等问题。特别是后一点给操作人员带来了很大的方便。

4. There is no cavitation damage and irrigation water diversion and other issues. Especially after a little to the operating personnel has brought great convenience.

5.振动噪声小，电机温升低，对环境无污染。

5. Vibration noise is small, the motor temperature rise is low, no pollution to the environment.

正是由于上述优点，潜水排污泵已越来越受到人们的重视，使用的范围也越来越广，由原来的单纯地用来输送清水到现在的可以输送各种生活污水、工业废水、建筑工地排水、液状饲料等等。

It is because of the above advantages, diving sewage pump has more and more get people's attention, the scope of use is becoming more and more widely, from simply used to transport water to the present can transport all kinds of sewage and industrial waste water, construction drainage, liquid feed and so on.
