Arm Cylinder For Liugong Middle Excavator CLG925D/925E

Introduction

An arm cylinder is a specially-designed hydraulic cylinder that is used to provide linear motion and power to various types of machinery, such as excavators, cranes, and robotic arms. Arm cylinders play a critical role in hydraulic systems, allowing for the effective movement and control of attachments or accessories. These cylinders not only enable smooth movement, but also have the ability to withstand heavy loads, ensuring efficient operation and reliability of the machinery under various work conditions.

Features

1. Efficient Power Transmission

The arm cylinder provides powerful linear motion and force to ensure high efficiency performance of the mechanical arm in various operations.

2. Precise Control

Through the hydraulic system, the arm cylinder can achieve precise motion control, making the operation of attached tools more flexible and accurate.

3. Strong Durability

The arm cylinder is typically made of high-strength materials with good wear and corrosion resistance, making it suitable for long-term use in harsh environments.

4. Multi-functional Adaptability

These cylinders can be widely used in various mechanical equipment, such as excavators, cranes, and robotic arms, to meet different working needs.

5. Easy Maintenance

The design considers ease of maintenance and replacement, making regular inspection and maintenance more convenient and reducing equipment downtime.

Applications

The arm cylinder is widely used in various industries, including:

1. Construction Engineering

The arm cylinder is used to control the movement of the bucket or boom in excavators and cranes to perform earthmoving, material handling, and installation of structures.

2. Manufacturing

The arm cylinder is used to control the movement of robotic arms in automated production lines for assembly, welding, and material handling processes, improving production efficiency and accuracy.

3. Agricultural Machinery

The arm cylinder controls the movement of the operating arm in agricultural machinery such as harvesters and seeders, performing tasks such as sowing, fertilizing, and harvesting.

4. Mining

The arm cylinder is used to control the arm movement of mining equipment for the extraction and transportation of minerals.

5. Logistics and Transportation

The arm cylinder is used to control the lifting and movement of forks in forklifts and handling robots for material handling and stacking.

Design Considerations and Selection Criteria

When designing and selecting an arm cylinder, several factors must be considered:

1. Load Capacity

The arm cylinder must be able to withstand the load and shock forces generated during the operation of the machinery.

2. Sealing

The arm cylinder should have a reliable sealing system to prevent leakage of hydraulic fluid and ingress of contaminants.

3. Durability

The arm cylinder should be made of high-strength materials with good wear and corrosion resistance to ensure a long service life.

4. Safety

The arm cylinder should be designed with safety features to prevent accidents caused by malfunctions or overloading.

5. Maintenance

The arm cylinder should be designed for easy maintenance and replacement of parts to reduce downtime and maintenance costs.

Sealing and Lubrication

The arm cylinder uses various sealing components, such as piston seals, rod seals, etc. The seals are made of wear-resistant materials such as polyurethane and nitrile rubber. The cylinder body and the threaded end face are finely processed to improve wear resistance. It requires regular addition of appropriate hydraulic oil for lubrication.

Maintenance and Repair

Regular inspection and preventive maintenance are essential for the proper functioning and longevity of the arm cylinder. The following measures should be taken:

1. Regularly check the sealing components for signs of wear or damage and replace them if necessary.

2. Check the cylinder body and the threaded end face for wear and damage, and repair or replace them if necessary.

3. Regularly add appropriate hydraulic oil for lubrication.

4. Check for leaks and repair them as soon as possible.

5. Perform regular load tests to ensure the arm cylinder’s load capacity.

Installation Guide

The installation of the arm cylinder should be carried out by professional personnel according to the following steps:

1. Clean the installation surface and the threaded connection end face of the cylinder to ensure that there is no dirt or damage.

2. Apply a proper amount of hydraulic oil to the sealing ring before installation.

3. Align the cylinder and the installation position, screw it in, and tighten it with a torque wrench according to the specified torque.

4. After installation, perform a no-load test and a load test to ensure that the arm cylinder operates smoothly and meets the required load capacity.
