How does a simple hydraulic system work?
A hydraulic system works by sending pressurized oil to the cylinder for it to act. By acting, the cylinder can move large loads, either by pushing or pulling them or for any other application where great force is required.

A hydraulic system works to do all this in a controlled way and with great precision, which makes it one of the best ways to transmit force in the modern era. A hydraulic system generally operates in a pressure range from 1,000 to 3,000 pounds.

1. A hydraulic pump is activated by an electric motor. When this happens the hydraulic pump generates the necessary oil flow for a cylinder to act.

2. When the cylinder acts the oil is returned to the oil tank through the pipe.

3. The oil is filtered by the Oil Filter. This is installed either in the pressure line or in the return line to remove any dirt that may flow into the pipe. This avoids failures or pressure losses in the hydraulic system.

4. A directional control valve controls the movement of the cylinder, that is, this valve causes the cylinder to expand or contract.
