CB-B-type gear pump output flow of the reasons and exclusion

CB-B-type gear pump output flow shortage reasons and exclusion â‘  high oil temperature will make it lower viscosity, increased internal leakage, so that the pump output flow decreases. Should identify the reasons for taking measures; for medium and high pressure gear pump, the seal to be checked for damage. â‘¡ the viscosity of oil selection is too high or too low, will result in reduced pump output flow, the viscosity should be qualified oil. â‘¢ CB-B gear pump generally can not be reversed, such as the pump body mounted anti-pressure pump will cause the cavity and the local short circuit to reduce or reduce the flow to the oil to. At this point, should check the pump steering. â‘£ engine speed is not enough, resulting in reduced traffic. Reason should be identified and be excluded.
