Hydraulic Actuator

The working principle of the hydraulic actuator is based on hydraulic transmission technology. When the actuator receives the control signal, the hydraulic oil pump begins to work, pressurizing the hydraulic oil into the hydraulic cylinder of the actuator. The piston in the hydraulic cylinder produces linear or rotational motion under the push of the hydraulic oil, which drives the valve to open or close. Hydraulic actuators are usually equipped with an accumulator, which can provide more than one execution operation in the event of a power failure, ensuring system stability and safety.

• Large driving force: The hydraulic actuator uses hydraulic oil as the power source, so it has a large driving force, which is suitable for the control of large valves and high pressure systems.

• Smooth action: Due to the incompressibility of the hydraulic oil, the hydraulic actuator can maintain a stable motion during the action, avoiding equipment damage caused by excessive impact force.

• High reliability: The hydraulic actuator has simple structure, stable operation, high reliability and durability, and is suitable for a variety of harsh working environments.

• Good adjustment performance: The hydraulic actuator can achieve accurate control of the valve opening by adjusting the flow rate and pressure of the hydraulic oil, and has high adjustment performance.

• Cast iron: Cast iron material has good mechanical properties and wear resistance, suitable for some high strength and wear resistance requirements.

• Carbon steel: Carbon steel material has high strength and good toughness, can withstand greater pressure and impact, so it is often used in the main parts of hydraulic actuators.

• Aluminum alloy: Aluminum alloy material has the advantages of light weight, corrosion resistance, easy processing, etc., suitable for some occasions where weight and corrosive media are required.
