Sturdy and durable vertical crystalline water ring sewage pump

Product Description

A sewage pump is a type of pump product that is connected to a motor and works underwater simultaneously. Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure and a small footprint. Easy to install and maintain, large sewage pumps are generally equipped with automatic coupling devices for automatic installation, making installation and maintenance quite convenient. Long continuous operation time. Due to the coaxial connection between the pump and motor, the shaft is short, and the rotating parts are lightweight, the load (radial) borne on the bearings of the sewage pump is relatively small, and the service life is much longer than that of ordinary pumps. There are no problems such as cavitation damage and water diversion. Especially the latter point brings great convenience to operators. Low vibration noise, low motor temperature rise, and no pollution to the environment.

Scope of use

① Wastewater discharge from enterprise units.

② Urban sewage treatment plant discharge system.

③ Subway, basement, civil air defense system drainage station.

④ Wastewater discharge from hospitals, hotels, and high-rise buildings.

⑤ A sewage drainage station in a residential area.

⑥ Discharge of slurry in municipal engineering and construction sites.

⑦ The water supply device of the water plant.

⑧ Wastewater discharge from breeding farms and irrigation of rural farmland.

⑨ Exploration of mines and supporting water treatment equipment.

⑩ Instead of carrying people's shoulders, suck and deliver river mud.

Working principle of KYJSB series vacuum mixing sewage pump

A certain amount of working liquid is installed in the vacuum sewage mixing pump, and the rotor is eccentric in the pump cavity. The rotor throws the liquid to the outer ring through high-speed rotation, forming a water ring near the shell wall. The water ring acts as a water seal in the pump, forcing the gas to move forward along the shaft in the pump. Because there is more liquid under the pump, the gas is compressed every revolution in the pump, and because the inner diameter of the rotor impeller gradually increases with the flow direction of the fluid, the flow space of the gas in the pump is gradually reduced, and the gas is continuously compressed with the rotation of the rotor, resulting in vacuum. When the sewage collection terminal starts to wash the sewage, the sewage pipeline will suck the sewage into the pipeline by the pressure difference.

The use of vacuum sewage churning pump makes the whole sewage system discharge linearly, without the need for additional auxiliary equipment such as vacuum starting device, flow pipeline and vacuum sealing box, which greatly simplifies the whole system structure, making the whole vacuum sewage system more compact, easy to install, flexible, safe and reliable. What is more important is that the vacuum sewage mixing pump solves the problem of seal leakage.
