潜水排污泵的优点： 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： 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。 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。 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。 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。 5.振动噪声小，电机温升低，对环境无污染。 阀门 进口泵 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。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。

Submersible sewage pump advantages: Submersible sewage pump: a pump and motor Siamese, while sneaking into the work of the pump liquid products, and generally horizontal or vertical sewage pump pump compared to submersible sewage pump obvious advantages with the following aspects: 1. Compact, small footprint. Submersible sewage pump liquid as sneaking into work, it can be directly installed in the sewage pool, without the need for specialized pumping station pumps and machines used to install, can save a lot of land and infrastructure costs. 2. Easy installation and maintenance. Small, free installation of submersible sewage pump, submersible sewage pump large are generally equipped with automatic coupling device can be automatically installed, the installation and maintenance very easy. 3. Continuous operation a long time. Submersible sewage pump because the pump and motor coaxial, shaft short, rotating parts, light weight, so the pressure on the load bearing (radial) is relatively small, life is much longer than the pump. 4. There is no cavitation damage and irrigation water diversion issues. The latter point in particular to the operators is a big convenience. 5. Vibration noise, motor temperature and low environmental pollution. Import pump valve It is because of these advantages, submersible sewage pump more and more attention has been paid, use the range more widely, from the simply to transport water to the present can transport all kinds of domestic sewage, industrial waste, construction site drainage, liquid feed and so on. Municipal engineering, industrial, hospital, construction, hotels, water conservancy construction and other industries play an important role.
