Submersible sewage pump and the difference between the general sewage pump
Submersible sewage pump is a pump and motor Siamese, and at the same time dive into the work under the pump products. It is compared with the general horizontal sewage pump or vertical sewage pump. Submersible sewage pump has the following advantages: 1, it does not exist cavitation damage and irrigation water and other issues. Especially after the point to the operator has brought great convenience. 2, small vibration and noise, motor temperature rise is low, no pollution to the environment. 3, compact structure, small footprint. Submersible sewage pump because it is submerged work. Therefore, it can be directly installed in the sewage tank. There is no need to build a dedicated pump house to install the pump and machine, which can save a lot of land and infrastructure costs. 4, easy installation and maintenance. Small submersible sewage pump can be freely installed, large submersible sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance quite convenient. 5, continuous operation for a long time. Submersible sewage pump due to pump and motor coaxial, short shafts, rotating parts light weight, so the bearing load (radial) is relatively small, longer life expectancy than the average pump. It is because of the above advantages, submersible sewage pump has been more and more people's attention. The range of use is also getting wider and wider, from the original purely for the transport of fresh water to the present can transport a variety of domestic sewage, industrial wastewater, construction sites drainage, liquid feed and so on. In municipal engineering, industry, hospitals, buildings, restaurants, water conservancy construction plays a very important role in all walks of life. But everything is split in two, the most critical issue for submersible sewage pumps is reliability. Because the submersible sewage pump is used under the liquid occasions; the medium is transported with some mixed liquid containing solid material; pump and the motor close. Pump vertical layout, the weight of rotating parts and impeller water pressure in the same direction. These problems make the submersible sewage pump in sealing, motor carrying capacity, bearing arrangement and selection requirements than the average sewage pump is higher.
