Stirring and discharging water ring vacuum pump

Overview of KNCSB series vacuum mixing sewage pump

KNCSB series vacuum churning sewage pump is a kind of pump equipment applied to non-gravity sewage discharge of ships. It integrates the functions of vacuum pumping, transportation and churning sewage. It has the characteristics of simple system, low flushing water volume, small sewage collection volume, small pipeline diameter, no inclination requirement, no blockage, flexible installation and layout, strong vertical lifting capacity, low investment and operating costs, and is applicable to modern ships, ships, trains, camping equipment,Pollution discharge from modern buildings, environmentally friendly kitchens, etc.

Features

▲small size, light weight, quick and flexible installation.

▲pipeline installation, direct discharge to sewer, sewage treatment plant or collection tank.

▲multiphase design, the pump can pump and discharge gaseous, liquid and solid combined phases.

▲low energy consumption.

▲stainless steel and bronze anti-corrosion materials are used for long service life.

Advantages of sewage pump

①Linear installation, no vacuum tank required, saving a lot of space in the ship;

②No foam;

③High vacuum pumping efficiency and low energy consumption;

④The waste can be directly discharged to any specification of sewage processor and sewage collection tank;

⑤Flexible pipeline installation;

⑥The system has high reliability.

Operating environment and working conditions

     KNCSB-120 is the most widely used vacuum pump in KNCSB series vacuum mixing sewage pump. It is a kind of pump specially designed for toilet to pump and press feces, urine and sewage. It is a three-phase flow vacuum churning sewage pump that combines vacuum, churning and pressure delivery.KNCSB vacuum agitation sewage pump is mainly used for all kinds of sewage that need to be transported in a closed manner Vacuum toilet. It can also be used to transport general chemical sewage, sludge and other wastes Close.

Working principle of KNCSB 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.
