Submersible sewage pump can sewage long fibers, bags, belts, grass, cloth and other substances torn, cut off, and then the smooth discharge, especially suitable for conveying liquids containing hard solids, fibrous materials and particularly dirty, sticky, slippery liquid . 　　 Large flow submersible sewage pump technology advantages: 　　 1, large flow submersible sewage pump compact structure, small size, easy to move, easy to install, no need to build pump room, dive into the water to work, greatly reducing project costs. 　　 2, the large flow submersible pump with double suction structure is low water absorption, double suction double spiral structure because of the single scroll, the motor without axial tension, reduce and balance the light to the force, greatly improving the life of the pump 3 Times, improve the use efficiency of 15%. 　　 3, the use of large runner anti-clogging parts design, greatly improving the ability to pass dirt, can effectively pass shorter fiber material and smaller diameter solid particles. 　　 4, configure the external circulation water pump device, you can work in low water level for a long time. Equipped with self-stirring even the impeller of the large flow submersible pump, with automatic mixing function, you can stir the pool of water, sewage sludge mixed with the pump. 　　 5, high-flow submersible sewage pump float switch can be based on changes in water level required to automatically stop the pump stop without special care. 　　 6, large flow submersible sewage pump can be equipped with automatic safety control cabinet according to user needs, the large flow submersible pump leakage, leakage, overload and over-temperature monitoring, to ensure reliable and safe pump operation. 　　 7, dual rail automatic coupling safety system, to the large flow submersible sewage pump installation, maintenance has brought great convenience, people do not have to enter the sewage pit for this purpose. 　　 8, there are features oil chamber with a leak probe, when the pump side mechanical seal damage, the water into the oil chamber, the probe sends a signal to pump protection. 　　 Encyclopedia: The most critical issue for the submersible sewage pump is the reliability of the problem, because the sewage pump is used in the occasion of liquid; conveying medium is mixed with a solid liquid mixture; pump and motor close to the pump; pump For the vertical layout, the weight of rotating parts and impeller pressure in the same direction. These problems make the sewage pump in sealing, motor carrying capacity, bearing arrangement and selection requirements than the average sewage pump is higher.
