                Wear reason of parts in gear pump of injection molding machine?

   Gear in the gear pump, rely on between the two gear meshing rotary conveying liquid, if the impurities in the liquid to be delivered (e.g., metal powder or sand mixed in a liquid) can accelerate the rapid wear of gear meshing face;If it is a support shaft bearing damage, the high speed rotating gear causes radial irregular beats, make two sets of gear mesh can not get the right position, sometimes turn the interference phenomenon will happen, it will speed up the gear wear and tear.Bearing severe wear will make the work gear produces about axial motion, two end face gear and the pump body inside the end cover of side friction, and make the gear side clearance increases, the infusion efficiency of gear pump, gear pump work noise increases.As a result, the gear pump cannot work properly and must be repaired.
