Sewage pumps are a type of centrifugal impurity pump and come in various forms, such as submersible and dry types. The most commonly used submersible type is the QW submersible sewage pump, while the most common dry type includes the W horizontal sewage pump and the WL vertical sewage pump. These pumps are primarily used to convey urban sewage, feces, or liquids containing fibers, paper scraps, and other solid particles. The temperature of the conveyed medium typically does not exceed eighty degrees. Due to the presence of easily entangled or aggregated fibrous materials in the conveyed medium, the pump's flow path is prone to clogging. Once clogged, the pump will fail to function properly, potentially damaging the motor and causing poor sewage discharge, which can severely impact urban life and environmental protection. Therefore, resistance to clogging and reliability are crucial factors in evaluating the performance of sewage pumps.
The sewage pump, like other pumps, has two core components: the impeller and the water chamber. The performance of these components directly reflects the overall performance of the pump. The clogging resistance, efficiency, cavitation resistance, and wear resistance of the sewage pump are primarily ensured by the impeller and the water chamber. The structure of the sewage pump is compact, occupying minimal space. Due to its submersible operation, it can be directly installed in a sewage tank without the need for a dedicated pump house to install the pump and motor, thus saving a significant amount of land and construction costs. Installation and maintenance are convenient. Small sewage pumps can be installed independently, while larger sewage pumps are typically equipped with automatic coupling devices, allowing for easy installation and maintenance. They have a long continuous operation time, low vibration and noise, minimal motor temperature rise, and do not pollute the environment.
With the progress of society, the continuous improvement of people’s living standards and the strengthening of environmental awareness, sewage pump has been known to people, and its application scope has become more and more wide.
