Gear pump extruder construction and extrusion process
Extruder gear pump having a pair of gears meshing with each other, as shown, the gear fixed to the driving wheel on the driving shaft, projecting end of the shaft driven by a prime mover housing, and the other gear wheel mounted on the driven shaft another When the gear rotates, the liquid enters into the suction space along the oil suction pipe and is squeezed by the two gears along the upper and lower shell walls respectively to meet the discharge space (before the teeth mesh with the teeth) and then enter the oil pressure pipe for discharge.
The concept of gear pump extruder is very simple, that is, its most basic form is that the same size of two gears in a close-fitting shell with each other engaged rotation, the shell is similar to the internal "8" shape, two gears Installed inside, the outer diameter of the gear and both sides of the shell with the close fit. The material from the extruder enters the middle of the two gears at the suction port and fills this space, moving along the housing as the teeth rotate, finally exiting when the two teeth mesh.
