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:
Compared with general horizontal or vertical sewage pumps, submersible sewage pumps have obvious advantages in 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 and small area. Submersible sewage pump can be directly installed in the sewage tank because it works under the water. 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.
2.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。
2. Easy installation and maintenance. Small sewage pumps can be installed freely, and large sewage pumps are usually equipped with automatic coupling device for automatic installation, installation and maintenance is quite convenient.
3.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。
3. 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.
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 are no cavitation damage and irrigation and diversion problems. Especially the latter point brings great convenience to operators.
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。在市政工程、工业、医院、建筑、饭店、水利建设等各行各业中起着十分重要的作用。
It is precisely because of the above advantages that diving sewage pumps have been paid more and more attention, and the scope of their use is becoming wider and wider. They are used to transport pure water from the original to various domestic sewage, industrial wastewater, construction site drainage, liquid feed and so on. It plays a very important role in municipal engineering, industry, hospital, construction, hotel, water conservancy construction and other industries.
