Research on valve-seat remaking for a motor cylinder cap |
| |
| Abstract: | The valve-seat of cylinder cap has been repaired and replaced, which belongs to a cut-off motor, with some special requirements for its fitting such as aluminium alloy welding, brush plating on valve-seat outside diameter and roll crushing for binding off. Through a great number of technical experiments, the remaking quality proved better than the new one＇s and a higher economic efficiency has been achieved. |
