What kind of seal is MECO seal?

Meigao seal is a patented product of an American company, which has been used as the screw seal of extruder in recent years. It mainly consists of a fixed plate, a shell, a gland, a sealed rotor, an elastic driver, a compensation spring and an adjusting nut. MECO sealing shell is made of carbon steel and aluminum, fixing plate is made of stainless steel, sealing rotor is made of polymer, and driving part is made of fluororubber or silicone rubber. By adjusting the gland, the two sealed rotors are in close contact with the central elastic driving part, and the fixed plate is in close contact with the gland, thus blocking the radial leakage of materials in the machine. The elastic driving part is also closely attached to the shaft, which in turn prevents the material from leaking in the axial direction. As the elastic piece and the shaft rotate together, the two sealing rotors are driven to rotate together. After the wear occurs, the spring can play the role of automatic compensation, and the adjusting nut can keep the spring within a certain length range, that is, the elastic driving part always keeps the pressure on the sealing surface.
