Excavator Cylinder Piston Rod Seals
Installation and application of piston rod seal for excavator hydraulic cylinder
The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
