Municipal sewage treatment system is like the kidney of a city. It uses a series of complex biological, chemical and physical treatment methods to treat domestic sewage and industrial sewage produced by the city every day to reach the water quality standards that meet the requirements of environmental protection. Sedimentation tank of sewage treatment system needs to install the bridge of mud scraper. When the bridge is running, the power supply and control signal are provided by the conductive sliding ring.
The sliding ring is installed in the rotating center of the equipment, which is divided into two parts: the rotor and the stator. The rotating part is connected with the rotor of the sliding ring, and the fixed part is connected with the rotor of the sliding ring. When installing, it is necessary to keep the conductive sliding ring unbearable, and keep part of the rotor and stator as a movable connection, so as to avoid damage caused by different concentricity of the rotor and stator in the process of installation, and the connecting wires are strictly forbidden to be pulled. Settlement pools usually have high effective humidity and corrosion, so conductive sliding rings usually need to be waterproof and anti-corrosion design, or additional protection outside the conductive rings, in order to avoid the failure or short circuit of conductive sliding rings.
