The usage method of hydraulic cylinders

The usage methods of hydraulic cylinders mainly include installation, operation, maintenance and troubleshooting, etc. The following will explain in detail:

Installation

1. Ensure that the installation position of the hydraulic cylinder meets the requirements and avoid placing it in an environment that is too hot or prone to vibration. .

2. Before installation, check whether the appearance of the hydraulic cylinder is intact and whether there are any bumps or damages.

3. Clean the connection surfaces between the hydraulic cylinder and other components and apply an appropriate amount of lubricating oil.

4. Securely and reliably connect the hydraulic cylinder to other components and oil pipes in the correct manner.

After installation is completed, conduct commissioning and inspection of the hydraulic cylinder to ensure its normal operation.

Operation

Before using the hydraulic cylinder, check whether the working pressure of the hydraulic system is within the specified range and confirm that the oil temperature of the hydraulic system is appropriate.

During the operation of the hydraulic cylinder, overloading operation should be avoided to prevent damage to the hydraulic cylinder or other mechanical equipment.

3. The operation of hydraulic cylinders must comply with safety production regulations. Do not engage in any illegal operations or use them beyond the prescribed scope.

Maintenance

The daily inspection of hydraulic cylinders includes checking whether there is any leakage at the connection points between the hydraulic cylinder and the pipe joint, the piston rod of the hydraulic cylinder, and the cylinder barrel of the hydraulic cylinder, as well as the hydraulic cylinder itself

Whether the work is normal and stable when moving.

2. Regular maintenance of hydraulic cylinders includes regularly tightening screws, replacing seals, and cleaning the hydraulic cylinders, etc.

3. To ensure the service life of the hydraulic cylinder, the medium used must not contain impurities or dirt to avoid scratching the inner arm of the cylinder barrel and causing damage to the sealing parts.

4. After the hydraulic cylinder is installed, before the trial operation, lubricating grease should be added to the relatively moving parts such as the ear ring and the middle hinge shaft.

Troubleshooting

When the hydraulic cylinder fails to work properly, the fault should be eliminated in time. Common causes of malfunction include leakage of the hydraulic cylinder, inability of the piston rod to rebound, and unsmooth movement of the piston rod, etc.

2. If leakage is found in the hydraulic cylinder, it is necessary to check whether the sealing parts are aged or damaged and replace them in time.

3. If the piston rod fails to rebound or moves unsmoothly, it may be due to surface collision or contamination of the piston rod. The piston rod should be cleaned or replaced in time.

In addition, when storing hydraulic cylinders, they should be kept in a dry, clean indoor environment free of corrosive gases, and attention should be paid to protecting the hydraulic cylinders from internal corrosion and external damage
