Understanding Electric Hydraulic Cylinders
Electric hydraulic cylinders are a subtype of electric cylinders that utilize hydraulic fluid to achieve linear motion. These devices offer unique advantages in terms of force output and control, making them ideal for various applications. Unlike traditional hydraulic cylinders, electric hydraulic cylinders are powered by electric motors, providing precise control over movement and reducing the need for hydraulic fluid replenishment.
How Electric Hydraulic Cylinders Work
Electric hydraulic cylinders operate by employing an electric motor to drive a hydraulic pump, which pressurizes hydraulic fluid. This pressurized fluid is then directed into a cylinder, causing the piston to move and generate linear motion. The closed-loop system is designed to minimize leakage and contamination, enhancing reliability.
