Quizplus · Accepted Answer

Both A and B are correct. Technician A is correct because the pump flow at maximum pressure should be at least 75% of the flow measured at 0 pressure in a simple hydraulic cylinder circuit. This is because the pump must be able to overcome the pressure in the circuit in order to move the cylinder. Technician B is correct because one way of checking internal leakage in a simple hydraulic cylinder circuit is to disconnect the return hose when the cylinder is actuated and watch for leakage. If there is leakage, it indicates that there is a problem with the cylinder seals or other components.
