Hydraulic Pressure vs. Flow: Understanding the Difference

 · In fact, a pressure problem in a hydraulic system is rarely the pump. It is almost always another bad component in the system. The pump should never be the first component to try but rather your last resort when a pressure problem exists.

(4) this kind of problem will occur when the opening pressure of the pilot safety valve is too low. At this time, we can not blindly adjust the pressure regulating screw of the total safety valve. We should check the safety valve to see whether the pilot valve spring is broken, whether the pilot valve seal is good, whether the main valve core is jammed and whether the main valve core damping.

Loader hydraulic problem

 · It works as a one way check valve so the pressure has to overcome the load before it will start raising. other wise the load would drop slightly before the pressure would start lifting the load. If the bucket hoses were reversed and the problem stayed the same it is not the valve.

Hydraulic cylinder rod travel is slower than normal

The single, most common problem with a hydraulic system is that the actuator (cylinder or hydraulic motor) slows down progressively as the oil temperature increases. There seems to be some confusion as to whether the problem is related to pressure, or flow, so let's clear the matter up.

and pressure determines system force. A hydraulic system that will not lift a load is likely experiencing a pressure related problem. One that will perform work, only slowly, is likely experiencing a flow related problem. NO FUNCTION = no pressure low flow.
