Manufacturing
In automated production lines, arm cylinders are used for the movement of robotic arms for assembly, welding, and material handling, improving production efficiency and accuracy.
Agricultural Machinery
In agricultural machinery such as harvesters and planters, arm cylinders control the motion of operating arms, performing tasks like seeding, fertilization, and harvesting.
Mining
In mining equipment, arm cylinders are used to control the arm movements of mining equipment, such as ore mining and handling.
Logistics and Transport
In forklifts and handling robots, arm cylinders are used to control the lifting and movement of fork blades, realizing the handling and stacking of materials.
Product Design Considerations and Selection Criteria
Load Capacity
The load capacity of the arm cylinder must be able to withstand the maximum load of the machinery during operation to ensure the safety and efficiency of the equipment.
Sealing
Various sealing components, such as piston seals and rod seals, are used to prevent hydraulic fluid leakage and ensure the normal operation of the cylinder. These seals must be made of wear-resistant materials such as polyurethane and nitrile rubber.
Durability
Arm cylinders are commonly exposed to harsh environments such as dust, moisture, and corrosive substances. Therefore, the cylinder body and threaded end surface need to be finely processed to improve wear resistance.
Safety and Maintenance
Providing a reliable safety device to avoid accidents is important when selecting an arm cylinder. Designing the cylinder for easy maintenance and replacement can reduce downtime and improve efficiency.
Sealing and Lubrication
Various sealing components, such as piston seals and rod seals, are used to prevent hydraulic fluid leakage and ensure the normal operation of the cylinder. The cylinder body and threaded end surface need to be finely processed to improve wear resistance. Regularly adding an appropriate amount of hydraulic oil for lubrication is necessary.
Regular Inspection and Preventative Maintenance
检查
Regular inspection of the arm cylinder is necessary to prevent unexpected failures that could lead to equipment downtime. Inspections should include checking the cylinder’s seals, threaded end surfaces, and wear and tear on the cylinder body.
Preventative Maintenance
Preventative maintenance measures include cleaning the arm cylinder regularly, replacing the hydraulic oil and seals when necessary, and replacing the cylinder if significant wear is detected.
Product Installation Guide
Pre-Installation
Before installation, check whether the cylinder specifications match the machinery requirements, and inspect the threaded end surfaces of the cylinder and the machinery to ensure they are clean and free of burrs.
Installation
During installation, pay attention to the alignment of the cylinder and the machinery and ensure the gasket and seal are installed correctly. Tighten the bolts according to the specified torque.
Post-Installation
After installation, check for leaks and ensure the cylinder is operating normally.
Product Safety and Environmental Considerations
When using arm cylinders, safety devices such as limiters and safety valves should be installed to ensure the safe operation of the equipment and avoid accidents. Arm cylinders should be disposed of properly to avoid polluting the environment.
