The steps for the disassembly and assembly of the piston ring of the ship machinery accessories are as follows:
1. Lift the ship engine fittings piston out of the cylinder.
2. Clean carbon deposit. Piston ring of ship machinery accessories with stuck phenomenon can be tapped with rubber hammer after soaking in light diesel oil to make it move, and chisel pin shall not be used.
3. The jaws of the piston ring pliers of the ship machinery accessories are firmly installed on the quantity of the ring, and the ring is slowly opened carefully, so that the inner diameter is slightly greater than the ring groove; Or one person can put the two nooses on the two mouths of the ring respectively, hook the nooses with the thumbs of both hands respectively, and then carefully pull the nooses outwards to make the ring open. Be careful to keep the ring concentric with the piston at all times.
4. Stabilize the opening of the ring lap, carefully lift the ring (or load), adjust the concentricity of the ring and the piston at any time, so that the gap between the ring and the piston in the same ring can be evenly removed (or loaded).
5. During disassembly, remove the rings one by one from both sides to the middle to reduce the distance between the rings during disassembly and assembly. Also, arrange the sequence of the piston rings of the ship machinery accessories and mark the working face at any time. For small and medium-sized diesel engines, can be removed from a ring root down.
6, ship parts piston ring assembly, first install the middle ring and then from both ends into the root, the order of arrangement, working face and the direction of the oil ring can not be wrong (for small and medium-sized diesel engines from the end of the oil ring one by one to mount).
