Graphite Filled Ring
Sealing structure and working principle
The composition and normal installation sequence of the graphite filled ring, the graphite filled ring is installed in the cup groove of the graphite filled ring, from the high pressure side to the low pressure side, the decompression ring for decompression; the main seal ring group for sealing; The main seal ring group consists of a radial ring and a tangential ring. The main seal ring under high pressure conditions usually has a choke ring to ensure the working stability of the tangential ring and prevent deformation under high temperature and high pressure. The main function of the tangential ring is sealing, and the function of the radial ring is decompression and pressure relief.
In the absence of gas pressure, spring force acts on the packing ring to pack the ring lobes around the piston rod. Graphite filled rings float freely in the cup groove to compensate for radial runout of the piston rod. The relative position is fixed by a pin/hole structure between the sealing rings, the slit gap of the tangential ring is covered by the radial ring, and the leakage path is closed, the gas enters the cup groove of the graphite filled ring from the axial gap and the radial gap, and the gas pressure The graphite filling ring forms a seal with the surface of the piston rod and the end surface of the cup groove respectively.

Graphite Filled Ring Installation Precautions
1. There must be a certain chamfer on the edge of the inner hole of the section of the graphite filled ring.
2. There should be no scratches on the inner surface of the graphite filled ring and the surface of the shaft (especially axial scratches and rust, the surface is required to be smooth.
3. After installation, properly tighten the nuts of the gland bolts by hand, and then rotate them by hand. It is appropriate to feel moderate, and then carry out commissioning and operation and allow a small amount of leakage, but then gradually reduce it. If the leakage is still large , the bolts can be properly tightened, but not too tight, so as not to burn the shaft.
4. If the graphite sealing ring has failed, if the cause is a problem with the graphite sealing ring, it can be dealt with by replacing or adding a graphite sealing ring to make it work normally
