Hydraulics Systems Diagrams and Formulas
The above system shows a front end loader powered by a PTO driven pump. A 2-spool directional control valve with built-in relief controls the lift and bucket cylinders of the loader. A return line filter is used to prevent contamination.
The diagram shows a winch powered by a hydraulic motor. The directional control valve with built-in relief features optional flow control to control the speed of the winch . The hydraulic pump and motor must be matched to the torque requirements of the winch.
A directional control valve with optional pressure kickout feature controls a double acting cylinder. A pressure gauge is recommended to help spot potential system problems. The tank should be at least one and a half times the pump gpm output and the oil level must remain above the pump intake at all times. (See Logsplitter Safety for more detailed information.)
