How to overhaul the Copeland D6 Piston?

(Summary description)When the Copeland D6 Piston is severely worn, the elasticity is weakened or the clearance increases, it will cause the compressor's lubricating oil consumption to increase and the cooling capacity to decrease. During inspection, the Copeland D6 Piston should be removed for visual inspection and a micrometer should be used for inspection.

Information

When the Copeland D6 Piston is severely worn, the elasticity is weakened or the clearance increases, it will cause the compressor's lubricating oil consumption to increase and the cooling capacity to decrease. During inspection, the Copeland D6 Piston should be removed for visual inspection and a micrometer should be used for inspection. When one of the following situations occurs, it should be replaced with a new one.

Copeland D6 Piston
(1) When the radial wear of Copeland D6 Piston is more than 1mm;
(2) When the axial wear of Copeland D6 Piston is above 0.2mm;
(3) When the axial clearance of Copeland D6 Piston in the ring groove exceeds 0.06~0.1mm;
(4) When the total length of the clearance between the Copeland D6 Piston surface and the cylinder mirror surface exceeds 30% of the cylinder circumference;
(5) When the Copeland D6 Piston is severely worn and loses its elasticity.
Since the temperature and lubrication conditions of the several rings on the Copeland D6 Piston are different during the compressor operation, the first ring wears faster under normal circumstances, but because the thickness of the new and old rings is different, if only the first ring is replaced , It is not good for the sealing of the cylinder, so it is best to replace all the rings on a Copeland D6 Piston together when changing the rings.
