Submersible sewage pump sewagecanlongfibers, bag, belt, grass, cloth and other material tear, cut, thensmoothdischarge, particularly suitable for conveying with hard solids, fibers, liquid and particularly dirty, sticky, slippery liquid, so in the use of submersible sewage pump seal is especially important let's take a look at it, what is the role of sealing:

The submersible sewage pump seal refers to the installation of an open impeller in the opposite direction near the back of the coaxial pump impeller hub. When the pump works, the auxiliary impeller rotates along with the main shaft of the pump. The liquid in the auxiliary impeller will rotate together. The rotating liquid will generate an outward centrifugal force. On the one hand, the centrifugal force will stop the liquid flowing to the mechanical seal and reduce the pressure at the mechanical seal.

On the other hand, the solid particles in the medium are prevented from entering the friction pair in the mechanical seal, reducing the wear of the mechanical seal grinding block and prolonging the service life.

Vice impeller submersible sewage pumps play a role in addition to sealing, but also can reduce the axial force in the submersible sewage pump is mainly in the axial force acting on the impeller on the liquid pressure force and the rotating part of the gravity of the composition, the direction of the two force is the same as the force is formed by the sum of two forces.

The above is the effect of sealing the submersible pump, it can offset a part of the axial force, and play a role in prolonging the life of the bearing.
