Installation steps for SANY hydraulic cylinder seals
1. Preparation: Clean the working surface and seals, and check if the seals are damaged or deformed.
2. Apply lubricant: Apply a layer of lubricant to the seal and sealing groove.
3. Install the seal: Place the seal into the sealing groove, ensuring that the seal is fully embedded in the groove.
4. Install O-ring: Install the O-ring above the seal, ensuring that the O-ring is fully inserted into the groove.
5. Install the piston rod: Insert the piston rod into the seal and O-ring, ensuring that the piston rod fits tightly with the seal and O-ring.
6. Install the sealing sleeve: Place the sealing sleeve on the piston rod to ensure that it fits tightly with the piston rod.
7. Tighten the nut: Use the nut to fix the sealing sleeve on the hydraulic cylinder, ensuring that the sealing sleeve is secure.
8. Check the sealing effect: Operate the hydraulic cylinder and check if there is any leakage in the sealing element. If there is any leakage, reinstall the sealing element.
