• An electro-hydraulic thruster is a robust device engineered to handle the intense conditions of heavy-duty machinery across various industries. It combines electrical and hydraulic technologies to deliver powerful and reliable mechanical force.

1. Motor and Centrifugal Impeller:
• The thruster includes an electric motor that drives a centrifugal impeller. This impeller is a rotating device with blades that move fluids outward due to centrifugal force. When the motor is powered, the impeller draws hydraulic oil from a low-pressure area and pushes it to a high-pressure area within the chamber of the thruster.
2. Hydraulic Chamber:
• The thruster has a chamber where the hydraulic oil is pressurized. The centrifugal force generated by the impeller creates the necessary fluid pressure to operate the device.
3. Piston and Shaft:
• The hydraulic pressure generated by the impeller acts on a piston mounted on a shaft. This piston moves upwards, generating mechanical thrust. The shaft is connected to the piston, and as the piston moves, it pushes the shaft to the upper end of its stroke. The thrust generated is used to perform various mechanical tasks.
4. Stroke and Stopper:
• The piston moves within a defined range known as the stroke. At the end of the piston’s movement, a stopper halts the piston’s travel, preventing it from moving beyond its designed limit. This stopper ensures the thruster operates within safe and precise parameters.
5. Oil Immersion:
• All the moving parts within the thruster are immersed in hydraulic oil. This immersion helps reduce frictional losses during operation. Since the moving parts are lubricated and cooled by the oil, the friction is minimized, leading to more efficient operation and reduced wear on components.

Electrical and Mechanical Specifications

1. Power Supply:
• The thruster is designed to operate with a 400/440V three-phase alternating current (AC) power supply. This specification indicates that the device is suitable for industrial power systems, which typically use three-phase AC for efficient and stable power distribution.

Applications

• Electro-hydraulic thrusters are used in heavy-duty machinery where precise and powerful mechanical force is required. Common applications include industrial presses, lifting equipment, and other machinery where hydraulic force can be effectively utilized.
