Filter Press Hydraulic Cylinder Sealing Ring
The seal ring of the hydraulic cylinder in the filter press primarily serves to prevent hydraulic oil leakage, ensure the hydraulic system operates smoothly, and maintain the pressure stability of the hydraulic cylinder. Using high-quality seal rings helps minimize friction, prolong the lifespan of the equipment, and enhance overall work efficiency.
How to Replace the Seal Ring?
Disassemble the hydraulic cylinder
Shut down the hydraulic system, release the pressure valve, and ensure that no pressure remains within the system. Begin by loosening the oil pipe joint and carefully draining any residual hydraulic oil. Use a wrench to remove the hydraulic cylinder fixing bolts and remove the hydraulic cylinder from the equipment. Use tools to remove the cylinder head and piston rod, and slowly pull out the piston assembly.
Remove the old seal ring
Use a small screwdriver or special removal tool to gently pry up the seal ring to avoid damaging the seal groove. Wipe the seal groove with a clean dust-free cloth to remove oil and impurities.
Install the new seal
Choose a suitable seal and apply a layer of hydraulic oil or lubricating oil on the surface of the new seal. Bend the seal and slowly insert it into the seal groove. A plastic tool or rubber rod will assist in the installation. Make sure the seal fits flatly.
Reinstall the hydraulic cylinder
Slowly insert the piston assembly back into the hydraulic cylinder and tighten the fixing bolts with a wrench to ensure a good seal. Reconnect the hydraulic oil pipe and tighten the joint to prevent oil leakage.
In What Situations Is It Necessary to Replace the Seal Ring?
Aging or damage to the seal ring: If the seal ring is aging, cracking, deforming, etc., it needs to be replaced in time.
Equipment leakage: If the equipment leaks hydraulic oil or other liquids, it may be caused by damage to the seal ring. You need to check and replace the seal ring.
Equipment has not been used for a long time: If the equipment has not been used for a long time, the seal ring may be old or damaged. It is recommended to check and replace the seal ring when it is used again.
