I ask what is the centrifugal pump mouth ring, impeller mouth ring?
Mouth ring, also known as sealing ring, or called wear-resistant ring. The main role is to prevent the media back back to the inlet outlet end is sealed medium (hence the name "ring"); at the same time also wear, avoid direct contact with the impeller and pump casing damage, protect the function of an impeller (hence the name "wear ring"). The form of the mouth ring includes: L type nozzle type sealing ring, double L type double sealing ring, inner engagement type single labyrinth sealing ring, labyrinth type double sealing ring, etc..
The installation position of the finger ring is different, and the impeller is mounted on the impeller, and the mouth ring is arranged on the pump body.
The mouth ring refers to the contact surfaces of two objects, such as the impeller and the pump shell, and the inlet of the impeller overlaps with the water inlet of the pump shell, but the gap is that the impeller can rotate, and the place called the retaining ring is also overlapped and then can not rotate
Centrifugal pump mouth ring generally refers to the impeller mouth ring, is installed in the water pump impeller and pump body between the ring metal ring, the shape of the figure:Turn left and turn right |
