1. 180-degree hydraulic rotary actuator overview
180-degree hydraulic rotary actuator is a device that converts hydraulic energy into rotary mechanical energy and is widely used in many fields.
180-degree hydraulic rotary actuator has many advantages. First, it can achieve efficient energy conversion in a compact space. For example, WEITAI’s hydraulic rotary actuator has large torque output and good load-bearing capacity in a compact size. Our WL20 series is easy to design for a wide range of applications, with high thrust capacity and high impact resistance for 180° rotation. Secondly, the actuator has enclosed moving parts, suitable for harsh environments, and durability. Furthermore, it can achieve zero internal leakage, smooth operation, no external braking, and stable position.
From the perspective of industry application, 180-degree hydraulic rotary actuator plays an important role in the oil and gas industry, metal and mining industry, power generation industry, chemical and petrochemical industry and other fields. In the oil and gas industry, it can be used to control the rotation operation of equipment such as valves; in metal and mining, it can assist the precise rotation of mechanical equipment; in the power generation industry, it provides reliable rotation power for the operation of various equipment.
2. Comparison of advantages
(I) Comparison with electric actuators
180-degree hydraulic rotary actuators have higher torque output than electric actuators. For example, in some industrial scenarios that require large torque, such as the control of large valves, hydraulic rotary actuators can easily achieve precise rotation control, while electric actuators may require larger volume and power to achieve the same effect. In addition, hydraulic rotary actuators are more adaptable in harsh environments and can withstand harsh conditions such as high temperature, high pressure, and high humidity, while electric actuators may be affected by environmental factors, resulting in performance degradation or failure.
(II) Comparison with pneumatic actuators
180-degree hydraulic rotary actuators generate several times more force than pneumatic actuators. As mentioned in the information, the force generated by hydraulic actuators is 25 times that of pneumatic actuators. This gives hydraulic rotary actuators a clear advantage in situations where high force output is required, such as the operation of heavy machinery. At the same time, hydraulic rotary actuators have better accuracy and stability, and can achieve more precise position control. Although pneumatic actuators have the advantages of simplicity, durability, easy installation, and safety, they are relatively weak in force output and accuracy.
(III) Comparison with other hydraulic actuators
Compared with traditional hydraulic actuators, 180-degree hydraulic rotary actuators have a unique 180-degree rotation function and are suitable for specific industrial scenarios. For example, in some equipment that requires precise control of the rotation angle, such as the rotation device of an automated production line, 180-degree hydraulic rotary actuators can provide more accurate rotation control. In addition, its compact design and high-power density make it more advantageous in situations where space is limited, and it can replace multiple traditional hydraulic actuator components, simplify the system structure, and reduce costs.
3. In General
180-degree hydraulic rotary actuators have unique advantages over other types of actuators in terms of performance and applicable scenarios, providing more efficient and reliable solutions for industrial production. 180-degree hydraulic rotary actuators occupy an important position in modern industry with their unique performance and wide range of applications.
