Applications

• Excavators: In excavator booms or buckets, hydraulic cylinders may be damaged due to long-term use or overload and need to be replaced to restore normal operation.
• Cranes: The boom hydraulic cylinders of cranes are prone to wear and tear during frequent lifting and lowering and need to be replaced regularly to ensure safety.
• Tractors: The front-end loader hydraulic cylinders of tractors may leak or perform poorly during continuous lifting and tilting operations, requiring replacement.
• Harvesters: During harvesting, the hydraulic system is under high pressure, and cylinders may be damaged due to fatigue, requiring timely replacement to maintain work efficiency.
• Automated production lines: Hydraulic cylinders are used to control robotic arms and other automation equipment. If the cylinder fails, it will affect production efficiency and need to be replaced immediately.
• Die-casting machines: Hydraulic cylinders may experience performance degradation in high-pressure and high-temperature environments. Regular replacement can ensure product quality.
• Mining equipment: Hydraulic cylinders are used to lift and move heavy objects in mining equipment. Due to harsh working conditions, regular inspection and replacement are necessary to avoid equipment failure.
• Bulldozers: The wear of hydraulic cylinders on bulldozer blades may cause a decrease in their pushing capacity, requiring timely replacement to maintain operational efficiency.

Maintenance

Regular inspection

Regular inspection is necessary to ensure the proper functioning of hydraulic cylinders. During inspection, it is important to check for leaks, cracks, and other signs of wear.

Proper lubrication

Hydraulic cylinders require appropriate lubrication to function properly. It is important to use the correct type of lubricant and apply it in the right amounts and at the right intervals.

Seal replacement and calibration check

Seals can wear out over time, causing leaks and other problems. It is important to replace them as needed. Calibration checks should also be performed regularly to ensure the cylinder is working correctly.

During installation, it is important to provide guidance on correctly aligning the cylinder and to recommend the use of appropriate installation brackets to secure the cylinder. Recommended inspection, repair, and replacement procedures should be provided, along with replacement parts and rebuilding services to extend the life of the hydraulic cylinder.

Safety and Environmental Considerations

Using hydraulic cylinders safely is essential to prevent accidents and injuries. Safety measures should be taken during installation, maintenance, and operation to ensure that equipment is used safely and appropriately. Environmental considerations should also be taken into account, and hydraulic cylinders should be disposed of in an environmentally responsible manner.

Troubleshooting and Common Issues

• Leaking seals
• Worn piston rods
• Contaminated hydraulic fluid
• Damaged cylinder walls
• Insufficient fluid pressure

To diagnose and solve these issues, proper troubleshooting techniques and solutions should be used. Preventive measures should also be taken to minimize potential issues.

Design Considerations and Selection Criteria

• Load-bearing capacity
• Sealing capabilities
• Durability
• Safety features
• Serviceability

Hydraulic cylinders should be designed with these considerations in mind. The use of various seals, such as piston seals and rod seals, made of wear-resistant materials like polyurethane and nitrile rubber, can help improve sealing capabilities. Precise machining of cylinder walls and thread-end surfaces can also enhance wear resistance. Appropriate testing and quality control should be implemented to ensure that hydraulic cylinders meet the necessary standards and requirements.
