Electric hydraulic solenoids use electromagnetism to control hydraulic fluid flow. Here's how they function:
An electric hydraulic solenoid is designed to control the flow of hydraulic fluid using electrical signals.
Basic Operation
- Electromagnetic Induction: At its core, a hydraulic solenoid operates similarly to a standard solenoid.
- Coil and Core: An electromagnetically inductive coil is wound around a metal core.
- Magnetic Field Generation: When an electric current passes through the coil, it creates a magnetic field.
- Mechanical Force: The magnetic field acts upon an armature (a movable component within the solenoid). This interaction generates a mechanical force.
- Valve Actuation: This mechanical force is used to shift a valve spool within the hydraulic valve, directing the flow of hydraulic fluid.
In essence, the electrical energy is converted into mechanical energy via electromagnetism, allowing the solenoid to control the hydraulic system.
