Hydraulic Pump Basics Hydraulic Pump Purpose - parker

Hydraulic Pump/Motor Division Increasing the pump drive speed will increase the pump output flow, but since the load sense control is working to maintain a constant pressure drop across the orifice, the load sense pump will destroke to maintain the same output flow. Therefore, in a load sense circuit, the pump will maintain the same

Hydraulic Maintenance & Troubleshooting

Isolating portions of the circuit is a good way to identify the area of concern. Lacking pressure? -Try to isolate the hydraulic system from the rest of the system by blocking the pressure source. Close a ball valve, disconnect a line and plug, etc. Lacking flow -The flow is taking the path of least resistance.

Basic Hydraulic Theory | Cross Mfg.

Rotary hydraulic motor circuits are basically the same as cylinder circuits. Systems may be uni-directional or bi-directional (as shown). The amount of rotary force (torque) available from the motor is a function of pressure (psi) and motor size. Speed is a function of flow and motor size.

Proper use of an Orifice in a Hydraulic Integrated Circuit

The orifice is one of the most versatile components that we can add in our hydraulic circuit. The orifice can be used to limit the amount of oil in one part of our system, to bleed a pressure line to tank, or to transform a nervous and aggressive circuit into an efficient and highly controlled one.
