由江苏省东台市机械厂与89001部队共同研制的DD40型导杆式柴油打桩锤已通过部级鉴定。该锤配用JCJ40打桩架,可打植长度不超过16m,重量不大于6t的各类型桩。与原有杆式柴油锤相比有两个优点:一是调整了压缩比使该锤能在严寒气候或软土层上可靠启动;二是改进了燃烧室,使油束分布和柴油雾化更趋合理,燃烧更充分,因而
The DD40 type guide rod type diesel piling hammer co-developed by the Dongguan City Dongtai Machinery Plant and 89001 troops has passed the ministerial appraisal. The hammer is equipped with a JCJ40 piling frame, which can be used to plant various types of piles with a length of no more than 16m and a weight of no more than 6t. Compared with the original rod-type diesel hammer, there are two advantages: First, adjust the compression ratio so that the hammer can reliably start in cold weather or soft soil; Second, improve the combustion chamber, so that oil distribution and diesel fuel atomization More reasonable and more complete combustion
