When repairing machinery and equipment, through the inspection of the damage of china O-ring custom grooves, not only the damage status and the cause can be known, but also the relevant information of the hydraulic system can be obtained.
1. Radial cuts or bites in china O-ring custom grooves may be caused by excessive pressure, sharp contact angles, excessive sealing clearance of moving parts, or improper installation and soft rubber ring material, but it is not excluded. Long-term overheating of the hydraulic system, etc.;
2. The china O-ring custom groove produces axial cuts, which may be caused by scratches or uneven gaps during installation;
3. The flattening and deformation of the groove is caused by poor material and insufficient elasticity;

4. Serious wear is due to poor lubrication, and if it is twisted, it is improper installation;
5. If the china O-ring custom expands, it means that the hydraulic oil is not suitable or the rubber ring material is improper;
6. Its local damage may be improperly installed, or the oil contains impurities, or it may be caused by the rotating part;
7. China O-ring custom fracture means that the system is overheated. Check whether the oil quality type and pressure are too high, and whether the cooling condition is good.
