Application of Graphite Ring

The graphite ring adopts flexible graphite belt or flexible graphite packing, which is molded into ring products of different sizes. Adapt to hot water, high temperature, high pressure steam, heat exchange fluid, nitrogen, organic solvents, hydrocarbons, low temperature liquid and other media. Used for compressors, pumps, valves, chemical instruments, meters, etc. Pressure (Mpa):25 temperature (℃):-200~850 linear velocity (m/s):30 PH value: 0~14 graphite rings are divided into flexible graphite and carbon-graphite rings. Carbon-graphite rings are mainly used in the sealing of mechanical rotating parts. The carbon-graphite ring has the characteristics of high temperature resistance, corrosion resistance and wear resistance.

If the graphite ring is damaged or the cast aluminum rod is not blocked in the waterway, and the surface of the aluminum rod is rough, the graphite ring must be replaced.

1. Loosen the four-grain bolts of the crystallizer and remove the crystallizer from the die table.

2. Remove the three O-rings, unscrew the pressure ring with a special tool and take out the adapter plate.

3. Loosen the two hexagon socket bolts of the crystallizer, divide the crystallizer into two pieces, and pay attention to remove an O-ring between the two pieces of dies.

4. Invert and rotate the upper ring of the crystallizer on a small rotating table, and heat the crystallizer with a liquefied petroleum gas gun until the graphite ring falls off.

5. Put the upper ring of the crystallizer and install a new graphite ring. Pay attention to adding small materials to press the graphite ring. Apply lard once when the graphite ring is hot.

6. After natural cooling, install all materials and clean them up. Pay attention to the small O-ring and its position, and the overflow hole is aligned.
