The reasons for the leakage of the seal are detected by the simplest method
★.install problem
1. Errors in the installation direction of the seals cause leakage.
2. when installed in the pipeline or mixed with foreign bodies, dust into the sealed cavity caused by leakage.
3. assembly poor seal damage caused by leakage.
4. Seal surface scratches cause leakage.
★. Selection of seals parts
1. Pressure is too high, the hardness is too small seal extruded metal grooves.
2. sealing materials and media, the seal is softened or dissolved.
3. Seal used in the high temperature conditions, the seals material is carbon.
4. Low temperature causes the sealing material to harden and contract to cause leakage.
5. Line speed is too high, causing the seal fever, dry grinding carbide formation leak.
6. Poor lubrication of the use of working conditions led to the formation of leakage of seal wear.
7. use of the cavity subjected to vibration caused by leakage.
8. Dust caused by seal wear caused by leakage.
9. Seal hardness is too high, it can not completely fill the trench metal cause leaks.
10. Size and metal groove seal discrepancies cause leakage.
11. Selection of storage time is too long, the aging of the seal caused leakage.
