A hydraulic rotary actuator, also known as a hydraulic rotary motor or hydraulic swing actuator, is a device that converts hydraulic energy into rotational mechanical energy. It is mainly used in the following equipment.
Construction Machinery
Excavators: Used for the rotation drive of the bucket, boom and other parts of the excavator to achieve excavation, rotation and other actions, improve work efficiency and operational flexibility. For example, in excavation operations, the rotary cylinder can control the angle and direction of the bucket to make excavation more precise.
Crane: It plays the role of rotation drive in the crane’s boom, slewing platform and other parts to help the crane complete operations such as lifting, handling and slewing of goods. For example, hydraulic rotary cylinders are usually used in the slewing mechanism of automobile cranes to enable the crane to rotate flexibly in the horizontal direction.
Loader: The bucket of the loader needs to rotate at a certain angle to better load and unload materials. The hydraulic rotary cylinder provides power for the rotation of the bucket, making the loader’s operation more efficient.
Mining Equipment
Drilling trolley: When drilling, the drilling trolley needs to constantly adjust the angle and position of the drill bit. The hydraulic rotary cylinder can accurately control the rotation of the drill arm of the rock drilling rig to ensure the accuracy and efficiency of drilling.
Mining conveyor: used to drive the roller or sprocket of the conveyor to rotate, so that the conveyor belt can smoothly transport ore, coal and other materials. The powerful power and precise control ability of the hydraulic rotary cylinder can ensure the stable operation of the conveyor.
Agricultural Machinery
Tractor: Some tractors may use hydraulic rotary cylinders in the agricultural implement mounting device, cab and other parts to adjust the operating angle of the agricultural implement and the driver’s field of vision, improve driving comfort and operating efficiency.
Combine harvester: In the header, conveyor and other parts of the combine harvester, the hydraulic rotary cylinder can realize the rotation and swing of the parts, so that the harvester can better adapt to different crop harvesting needs.
Special Vehicles
Fire truck: The ladder, fire cannon and other equipment of the fire truck need to be rotated to achieve fire extinguishing operations. The hydraulic rotary cylinder provides reliable power support for these machines, ensuring that firefighters can extinguish fires quickly and accurately.
Sanitation vehicles: such as the compression device of the garbage compression vehicle, the garbage loading and unloading device, etc., need to rotate and swing, and the hydraulic rotary cylinder can help these devices complete the compression and loading and unloading of garbage.
Metallurgical Equipment
Rolling mill: During the steel rolling process, the rollers need to be constantly rotated and adjusted. The hydraulic rotary cylinder can accurately control the rotation speed and angle of the rollers to ensure the rolling quality of the steel.
Converter: The converter needs to rotate during the steelmaking process so that the molten steel can be evenly stirred and heated. The hydraulic rotary cylinder provides a strong power for the rotation of the converter to ensure the smooth progress of the steelmaking process.
Hydraulic Equipment
Gate opening and closing machine: used to control the opening and closing of the hydraulic gate. Through the drive of the hydraulic rotary cylinder, the gate can achieve smooth and accurate opening and closing operations, effectively regulating the water flow.
Turbine: The blades of the turbine need to be adjusted according to the changes in the water flow to improve the efficiency of the turbine. The hydraulic rotary cylinder can accurately control the rotation angle of the blades, so that the turbine can better utilize water energy.
Machine Tool Equipment
Machining center: In the tool magazine, workbench and other parts of the machining center, the hydraulic rotary cylinder can achieve fast and accurate rotation and positioning, improving the machining accuracy and efficiency of the machine tool.
Milling machine: The workbench or milling head of the milling machine needs to be rotated to process the workpiece at different angles. The hydraulic rotary cylinder can provide stable rotation power for the milling machine.
Robot: In some industrial robots and special robots, the hydraulic rotary cylinder can be used as a joint drive device to realize the rotation movement of the robot. For example, the arm joints of some handling robots and the welding gun rotation mechanism of welding robots may all use hydraulic rotary cylinders.
