我厂自1984年开始为中原、胜利等油田生产钻井泥浆泵高铬双金属缸套。多年来,我厂生产的缸套外套材质为ZG310—570,内套为高铬铸铁,均采用离心铸造工艺。使用的离心机是自制的悬臂式和滚轮式两种。内套的成品率很高,但外套因铸件壁厚,且带有腰箍而形成铸件壁厚不均。生产初 I plant since 1984 for the Central Plains, Victory and other oil production drilling mud pump high-chromium bimetallic cylinder liner. Over the years, I plant the liner jacket material ZG310-570, the inner sleeve is high chromium cast iron, are used centrifugal casting process. Centrifuges used are self-made cantilever and roller two. The inner sleeve of the high yield, but the jacket due to casting wall thickness, and with the formation of waistband castings uneven wall thickness. Production early
