Air Compressor Seal Ring for CNG Compressor

♠Description-Air Compressor Seal Ring for CNG Compressor

Most of the air compressor seal use O rings. Seals are mainly suitable for static seals and reciprocating seals. For rotary motion seals, only for low-speed rotary seals. The sealing gasket is generally mounted in a groove having a rectangular cross-section on the outer or inner circumference for sealing. The sealing gasket still plays a good role in sealing and damping in the environment of high-temperature resistance, oil resistance, acid, and alkali, grinding and chemical corrosion. Therefore, the gasket is the most widely suitable seal in hydraulic and pneumatic transmission systems.

The ends of these segments are chamfered to present sliding surfaces to tapered wedge pieces, one of which is interposed between the ends of neighboring segments. Besides, a garter spring seated in a groove around the outside circumference of the ring holds the assembly of segments and wedges together. Wear on the carbon is taken up by the action of the spring and water pressure continually forcing the segments into contact with the shaft, while the wedges move outwards. Thus wear of the carbon segment takes place while they still maintain an effective seal

Different designs of Compressor piston seals/Piston rod pressure packing

1. With leaked gas recovery (venting), mainly for process gases (inflammable, sour, toxic, wet or costly gases).

2. With (lubricated packing case) or without lubrication (dry packing case) according to the process specifications or as requested by the user.

3. With internal cooling. Cool the stuffing box when working under dry or high pressure.

4. With inert buffer gas (in accordance to API 618 ), to minimize residual leakage of the process gas. The packing case is equipped with a chamber into which is introduced an inert gas (usually nitrogen) at a higher pressure than the venting pressure.

5. With inert purge gas (in accordance to API 618 ). This alternative is based on the same principle as the inert buffer gas, in this case, however, the packing case has an inert gas inlet and outlet (there is only an inlet for the buffer gas).

6. With oil recovery in the case of combined packing cases.
