1、结构紧凑、占地面积小。潜水排污泵由于潜入液体内工作，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。推荐阅读：

1. The structure is compact and the area is small. The submersible sewage pump can be directly installed in the sewage pond because of its work in the liquid pool. No need to build a dedicated pump room to install pumps and machines, it can save a lot of land and infrastructure costs. Recommended reading:

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. It is convenient to install and maintain. Small submersible sewage pumps can be installed freely. Large submersible sewage pumps are equipped with automatic coupling device, which can be automatically installed, installed and maintained quite conveniently.

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。相关阅读：

3, the continuous operation time is long. The submersible sewage pump, because the pump and motor are coaxial, the shaft is short, and the weight of the rotating parts is light, so the load (radial) on the bearing is relatively small, and the service life is much longer than the ordinary 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 water diversion and other problems. In particular, the later point has brought great convenience to the operators.
