一,结构紧凑、占地面积小。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。
First, the structure is compact and the area is small. As the sewage pump works under the water, it can be directly installed in the sewage pool. There is no need to build a special pump house to install pumps and machines, which can save a lot of land and infrastructure costs.
二,安装维修方便。小型的排污泵可以自由安装,大型的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。
Second, easy installation and maintenance. Small sewage pumps can be installed freely, and large sewage pumps are usually equipped with automatic coupling devices for automatic installation, installation and maintenance is quite convenient.
三,连续运转时间长。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。
Third, the continuous operation time is long. Because the pump and motor are coaxial, the shaft is short and the rotating parts are light, the load (radial) on the bearing is relatively small, and the service life of the sewage pump is much longer than that of the general pump.
四,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。
Fourthly, there are no cavitation damage and irrigation and diversion problems. Especially the latter point brings great convenience to operators.
五,振动噪声小,电机温升低，对环境无污染。
Fifth, low vibration and noise, low motor temperature rise, no pollution to the environment.
