汽缸套是模锻锤上的典型易损零件。由于汽缸套是经常在润滑不良的情况下工作,所以容易加速磨损。用普通灰铸铁制造的汽缸套,两班制生产时,使用寿命为一年左右,甚至有个别的汽缸套一年要换两次。这样,不仅增加了维修费用,而且影响了生产的正常进行。为此,我们采用汽缸套的整体淬火和改变活塞环的材质两种方法来提高汽缸套的使用寿命。 Cylinder liner is a typical forging hammer on the vulnerable parts. As cylinder liner is often in the case of poor lubrication work, so easy to accelerate wear and tear. With ordinary gray cast iron cylinder liner, two shift production, the service life of about a year, and even individual cylinder liner to be changed twice a year. In this way, not only increased maintenance costs, but also affect the normal production. To this end, we use the overall cylinder liner quenching and changing the material of the piston ring in two ways to improve the service life of the cylinder liner.
