O-ring is a common seal. Improper removal and installation during the entire maintenance process can easily destroy the sealing ring. The article describes the key points of the removal, installation and attention of the sealing ring in the maintenance of equipment and machinery.
- Installation
1 can not destroy the lips
If there is a slight scar on the lips, it is likely to cause significant oil and steam leakage.
2 Regular inspection to prevent overdue embrittlement
Regular maintenance to avoid oil leakage and steam leakage in damage and embrittlement conditions, immediately remove and replace new sealing rings.
3 The specifications and models of the replacement must be consistent
The sealing ring of the same specification and model shall be strictly in accordance with the regulations to ensure the tightness regulations.
4 Dismantle and replace qualified products
Check the ductility and process performance before disassembly and replacement: the surface is smooth and has no defects such as unevenness and cracks before applying.
5 installation
Use common tools to prevent the sharp edges of the groove metal material from scratching your fingers. Before installation, clean the groove and wipe some grease on the lips. Do not knock it in hard. First press the sealing ring into the hole and groove, and then slowly, thoroughly and evenly press it in.
Second, the shape
Take the common O-ring hydraulic seal as an example. The seal ring is installed in the groove and has internal and external wall thickness applications.
Three, take out
Take the O-ring hydraulic seal as an example. A common tool is needed to remove the seal ring, such as a small hook made of millimeter stainless steel wire after cutting and production, and the small hook is parallel to the groove and applied to the groove. The small hook can be inserted into the bottom of the groove with a slight force, and the small hook is rotated by 90°, and the small hook linearly holds the O-ring, and then slightly applying force upward and inward can dig (pry) and take it out.
