The left side shows a small hydraulic circuit made in the FluidSIM software, the right side shows the internal configuration of the elements that make up this circuit. The single acting cylinder has been considered to move the block shown. The operation is as follows: When the pump is switched on, it allows the fluid to be sucked from the reservoir. The 3/2 valve is NC, so the flow cannot get through to the cylinder. This fluid, being incompressible, needs a place to release the flow and thus maintain the pressure, and that is where the pressure limiting valve opens so that the fluid returns to the reservoir. If the 3/2 valve is actuated, it allows flow to reach the cylinder thus causing the stem to move. When the pressure in the lines reaches its limit, then the safety valve is opened so that the fluid returns to the tank and thus avoid failures in the circuit. If the 3/2 valve is not pressed or actuated, it returns to its default state
allowing the flow to pass and thus the cylinder rod retracts due to the force generated by the block. A hydraulic circuit, unlike a pneumatic circuit, must necessarily have a pressure limiting valve since the fluid used, which can be oil, is incompressible compared to air. Also, in most cases the pump is kept on to ensure adequate pressure in the lines. It should be clarified that this is a basic and possibly ideal circuit, since several stages have not yet been considered as fluid filtering, the motor that provides the pump movement and other elements that will be seen in the next videos in more detail . This is a short introductory video to the basic hydraulics course that will be offered on this channel. You will also see processes using PLC.
