Abstract:
Double acting hydraulic pile hammer is a new large-scale mechanical
and electrical hydraulic high-level application of offshore engineering equipment,
which is the concentrated embodiment of high-pressure, large flow and high stability
hydraulic equipment. The cartridge valve is a new type of hydraulic component to
meet the working requirements of large-scale and fast hydraulic equipment. This paper
introduces the structure, characteristics and technical application of the cartridge valve
based on the power system of the new-type hydraulic hammer.
双作用液压打桩锤是新兴大型机电液高水平应用的海洋工程设备,是
高压、大流量、高稳定性的液压设备的集中体现。插装阀是新型满足大型快速
液压设备工作要求的液压元件,本文以新型液压打桩锤动力系统为载体介绍了
插装阀的结构、特性和技术应用。
