Single Acting Hydraulic Cylinder Seals , Hydraulic Piston Rings U Shaped UN

● Good abrasion resistance: It can maintain a longer service life in the frequent work environment and reduce the problem of sealing failure caused by wear. For example, in the hydraulic system of construction machinery, UN sealing parts can bear the reciprocating movement of the piston rod or piston for a long time.

● Excellent oil resistance: can effectively prevent the penetration and leakage of medium such as hydraulic oil, and ensure the normal operation of the hydraulic system. In the hydraulic systems of various industrial equipment, the system can be sealing and avoiding pollution and energy waste caused by oil leakage.

● Strong pressure resistance: It can withstand a certain degree of pressure, and can still maintain good sealing performance under high -pressure working conditions. For example, in some large hydraulic equipment, UN sealing parts can stably play a sealing effect.

Preparation before installation

1. Clean: Make sure the installation site (such as piston rods, pistons, grooves, etc.) is clean, dust -free, oil, stain, rust, and burrs. You can use clean cloth or solvents to clean.

2. Check:

• Check whether the specifications of the UN sealing parts are correct and whether the size of the installation site is matched.

• View whether there are problems such as damage, deformation, cracks or aging of the surface of the sealing part.

3. Lubrication: Before installation, you can apply an appropriate amount of lubricant (such as lubricating fat or oil) on the lip of the sealing part to reduce the friction during the installation and prevent the sealing of the parts from being damaged. However, it should be noted that the amount of lubricants should not be too much, and the lubricant that contains solid particles or is damaged to sealing materials cannot be used.

Installation step

1. Careful placement: Carefully place the UN sealing parts to the installation location to ensure that the lips of the sealing parts are in the correct direction (generally facing the side of the medium that needs to be sealed), and the sealing parts are fully expanded and fitted on the surface of the installation surface. superior. Avoid distorting, deformation or folding during the placement process.

2. Selection and use of installation tools:

• For smaller UN sealing parts, you can use your fingers to gently press to enter the installation location. However, for large or tight installation sites, it is necessary to use appropriate tools, such as the installation cover and pressing tools of plastic or rubber materials, and press the sealing parts into the groove or put it on the piston rod with a uniform power. Be careful not to use sharp and hard tools to avoid scratching secrets.

• If you use the installation set, you should ensure that the inner diameter of the installation set is slightly smaller than the outer diameter of the piston rod, and the end of the installation suit should be smooth and without burrs to avoid damaging the dense sealing lips during the installation process.

3. Precautions during the installation process:

• When installing the sealing parts in the groove, it is necessary to ensure that the sealing parts can enter the groove smoothly and smoothly, and must not be forcibly squeezed or knocked to avoid damaging the seal or deformation of the groove.

• For the UN sealing parts installed on the piston, in the process of setting into the pistachio, pay attention to prevent the sealing lips from being scratched by the thread, sharp edge or key slot of the piston rod. You can use a dedicated thin sleeve cover on these parts to play a protective role.

• If it is installed at the same time of multiple UN seals, pay attention to the installation location of each sealing part is correct, and keep parallel and uniformly with each other to avoid being installed or overly loose in a certain sealing part.

Installed inspection

1. Appearance inspection: After the installation is completed, check the appearance of the sealing part again to ensure that the sealing part is installed in place without distorting, deformed, protruded or damaged.

2. Function check: Before the device is started, you can perform simple manual testing, such as gently rotating or moving the piston rod to check whether the sealing parts can be freely moved, and the cooperation with the installation site is closely without stuck or loose.

3. Leakage test: When the device is running, closely observe whether the sealing site is leaked. If leakage is found, it should be immediately shut down to find out the cause of the leak and reinstall or replace the seal.

Different types and sizes of UN sealing parts may have some slight differences in the installation method. Therefore, it is best to refer to the product manual or related installation guide before installation. In addition, if you have any questions about the installation of UN sealing parts in specific devices or applications, it is recommended to consult a professional seal supplier or technician.
