I. Mounting Methods
1. Earring Mounting
This mounting method connects the hydraulic cylinder to the mechanical component via earrings at each end of the cylinder barrel. The earrings allow the hydraulic cylinder to oscillate within a certain range of angles, making it suitable for applications requiring oscillating motion.
The advantage is flexible installation, adapting to varying working angles. The disadvantage is its relatively complex structure and space requirements.
2. Flange Mounting
Flange mounting connects the ends of the hydraulic cylinder barrel to the mechanical component via flanges. This mounting method is secure and reliable, capable of withstanding large axial and radial loads.
It is suitable for applications requiring high stability, such as heavy machinery. However, its installation is relatively complex and requires precise alignment.
3. Foot Mounting
Foot mounting connects the hydraulic cylinder to the mechanical component via a foot at the bottom of the hydraulic cylinder. This mounting method is simple and convenient, suitable for small hydraulic cylinders and applications with limited installation space.
Foot mounted hydraulic cylinders offer greater stability, but their load-bearing capacity is relatively low.
There are some other forms of fixing methods, please see the figure below:
II. Installation Precautions
1. Pre-Installation Inspection
Before installing the hydraulic cylinder, carefully inspect the cylinder for damage and seals. If damaged, replace them promptly.
Also, check that the hydraulic cylinder model and specifications match the design requirements to ensure proper installation.
2. Installation Environment Requirements
The hydraulic cylinder should be installed in a clean, dry environment. Avoid installation in harsh environments such as those exposed to corrosive gases and dust.
The installation location should be convenient for maintenance and repair to ensure prompt repairs in the event of a hydraulic cylinder malfunction.
3. Installation Accuracy Requirements
When installing a hydraulic cylinder, ensure the accuracy of its connection to the mechanical components. Especially for flange-mounted installations, ensure the flange’s centering accuracy to avoid uneven force on the hydraulic cylinder due to improper installation, which could shorten its service life.
For earring-mounted installations, pay attention to the earring’s installation angle to ensure the hydraulic cylinder can swing within the correct range.
4. Hydraulic Pipe Connections
When connecting hydraulic lines, ensure they are clean to prevent impurities from entering the hydraulic cylinder and damaging seals.
Pipe connections should be secure and reliable to prevent leakage during operation.
5. Commissioning and Trial Run
After installation, the hydraulic cylinder should be commissioned and tested before official operation. Check for normal operation and abnormal noise and vibration.
During the commissioning process, gradually increase the load and observe the cylinder’s performance to ensure it meets operational requirements.
There are some important installation points, see the figure below:
Correctly selecting a hydraulic cylinder’s mounting method and strictly adhering to installation precautions are key to ensuring stable operation and extending the cylinder’s service life. In actual applications, you should select the appropriate mounting method based on specific work requirements and installation conditions, and carefully perform installation work to provide a strong guarantee for the equipment’s efficient operation.
