In general, I am a pump or vertical sewage pump compared to the sewage pump has the following advantages:
1. Compact structure, small floor area. Sewage pump due to sneak into the liquid, so it can be directly installed in the sewage pool, without the need for the construction of a dedicated pump is used to install pumps and machines, can save a lot of land and infrastructure costs.
2. Convenient installation and maintenance. Small sewage pump can be installed freely, large sewage pump is generally equipped with automatic coupling device for automatic installation, installation and maintenance is very convenient.
3. Continuous running time. Due to pump and motor coaxial, short axis, rotating parts of light weight, so the load bearing on the bearing (radial) is relatively small, life expectancy is much longer than the general pump.
4. Does not exist in the cavitation damage and irrigation water and other issues. Especially after a little to the operator has brought a lot of convenience.
It is because of these advantages, sewage pump has attracted more and more people's attention, use scope is more and more widely. From the original simple to transport water can transport all kinds of domestic sewage, industrial waste, construction site drainage, liquid feed and so on. In the municipal engineering, industry, hospitals, construction, hotels, construction and other industries play a very important role.
Disadvantages
But everything is divided into two, for sewage pump is the most critical problem is reliability problems, because the using occasion of the sewage pump is in the liquid, and the transmission medium is some mixed liquid containing solid materials, pumps and motors on the close, the pump for the vertical layout, weight and impeller rotating components to withstand water pressure in the same direction. These issues have made the sewage pump in the seal, motor bearing capacity, bearing arrangement and selection and other aspects of the requirements than the general sewage pump to high.
