1) Powertrain (including engine, gearbox, etc.).
2) Undercarriage: axle suspension
It is an individual material, or a composite material, or a design device, when placed in the joint plane of a pipe, container device, or
assembly fitting, the material or device will form a seal to prevent penetration, effectively blocking the leakage of the medium in the pipe or device.
Key features:
- It is a sealing body that prevents the medium (gas or liquid) in the pipeline or device from leaking outward.
- Maintains long-term sealing of pipes or installation systems.
- It can prevent impurities from outside the pipe or device system from entering the pipeline or device and causing contamination.
- Can help the flange plane design of the joint is inadequate.
- Makes the unit system easy to disassemble during maintenance.
- It can be used as a gap filling pad at both ends of the joint of the device system, so that the device system can always maintain a flat seal.
- It can help reduce the cost price of the connector device.
Leakage route of gasket:
Interface leakage: The sealing medium leaks from between the gasket and the flange face, and the seal fails.
Body leakage: The sealing medium leaks out from the gasket material itself, and the seal fails.
When analyzing a seal failure case, the first thing to do is to determine whether the failure is a leak or a leak.
