Gear pump is one of our common oil pump. Gear pumps can deliver any material with lubricity. Gear pump insufficient flow is one of its common problems. So, what are the reasons for insufficient gear pump flow? Serious wear and tear of the internal parts of the gear pump will lead to internal leakage, so that the gear pump flow is insufficient, affecting work efficiency. Suction or discharge Valve closed or semi-closed, or the phenomenon of leakage, but also make gear pump flow problems. Serious wear and tear gear, the gap between the gear is too large, thus affecting the pressure, the lack of flow. Material viscosity is too large, there will be the phenomenon of insufficient flow, accompanied by large noise problems. Strict seal, resulting in oil leakage, the pump inhaled air, affecting traffic. If it is not a mechanical problem, it is recommended to change the pump of the first gear.
