筒式柴油打桩机由于具有结构简单、操作方便、打击能量大、使用经济性好等优点,是目前使用比较普遍,并深受用户欢迎的一种桩工机械。但是它还存在一些缺点,其中软土起动性能差就是一个带普遍性的毛病。这是因为筒式柴油打桩机与普通柴油机不同,柴油机的功率是通过曲轴输出的,因此,外界负荷的变化对柴油机气缸内的燃烧过程影响不大;而筒式柴油打桩机的功率是通过下
Due to its advantages such as simple structure, easy operation, high impact energy, and good economy of use, the cylinder type diesel pile driver is a kind of pile-driving machinery that is widely used and popular among users. However, it still has some shortcomings. The poor start-up performance of soft soil is a common problem. This is because the diesel diesel pile driver is different from ordinary diesel engines in that the diesel engine power is output through the crankshaft. Therefore, changes in the external load have little effect on the combustion process in the cylinder of the diesel engine; the power of the diesel drum pile driver is
