Sealing and Lubrication of Arm Cylinder

The arm cylinder’s sealing and lubrication are essential factors that affect its service life and reliability. The following measures are usually taken:

Sealing Elements

The arm cylinder uses various sealing elements such as piston seals and rod seals to prevent fluid leakage and ensure the hydraulic system’s stable operation. The sealing elements are made of wear-resistant materials to ensure durability.

Cylinder Body and Threaded End Surface Treatment

The cylinder body and threaded end surface are usually treated with fine processing to improve the wear resistance. The surface of the cylinder body is usually chrome-plated, while the surface of the threaded end is usually treated by nitriding or carburizing.

Lubrication

The arm cylinder requires regular lubrication to maintain its good operating condition. The hydraulic oil used for lubrication should be selected according to the equipment’s working conditions and operating temperature, and the oil volume should be appropriate.

Regular Inspection and Preventive Maintenance Measures

Regular inspection and preventive maintenance measures can effectively ensure the arm cylinder’s stable operation and extend its service life. The following measures are usually taken:

Regular Inspection

The arm cylinder should be inspected regularly to detect possible problems timely. The inspection items usually include the cylinder body’s wear condition, the sealing performance, and the hydraulic oil’s contamination level.

Cleaning and Replacement of Hydraulic Oil

The hydraulic oil should be replaced regularly to ensure its cleanliness and prevent contamination. The replacement cycle should be determined according to the equipment’s working conditions and operating temperature.

Replacement of Worn Sealing Elements

The worn sealing elements should be replaced timely to ensure the arm cylinder’s sealing performance and prevent fluid leakage.

Replacement of Worn Parts

The worn parts such as the piston and rod should be replaced timely to ensure the arm cylinder’s good operating condition.

Installation Guide

The installation of the arm cylinder should follow the following steps:

Step 1: Prepare the Installation Environment

The installation environment should be clean and well-ventilated to ensure the cleanliness of the arm cylinder. The installation site should be flat and stable to ensure the equipment’s stable operation.

Step 2: Install the Cylinder

Install the arm cylinder according to the equipment’s installation requirements, paying attention to the installation direction and position. The cylinder should be installed securely and firmly, and the threaded connections should be tightened to the specified torque.

Step 3: Connect the Hydraulic Pipeline

Connect the hydraulic pipeline according to the equipment’s hydraulic system requirements. The pipeline should be clean and free of debris to ensure the hydraulic system’s stable operation.

Step 4: Test the Equipment

After installation, conduct a comprehensive test according to the equipment’s operating requirements to ensure the arm cylinder’s good operating condition.
