摘要
作为国内最早的土工离心机之一,南京水利科学研究院的NHRI-400 g·t大型土工离心机自1991年建成并投入使用以来,已经运行20多年。2016年—2017年,在不改变实验室房屋结构的前提下,该离心机经历了彻底的升级改造。升级改造工作的主要内容包括机械系统、电气系统和数据采集系统。不同于传统的直流电机-减速机驱动方式,升级后的离心机采用了全新的驱动方式,即力矩电机直接驱动。新的数据采集系统包括90个静态数据通道和38个动态数据通道。升级改造后的NHRI-400 g·t大型土工离心机已服务于若干研究项目,性能良好。
In Nanjing Hydraulic Research Institute(NHRI),the NHRI-400 g·t centrifuge has been operated for more than twenty years since established and put in use in 1991.It is one of the oldest machines in China.In 2016 and 2017,the machine was thoroughly upgraded without changing its basic engineering facilities.Upgradation is made mainly to the mechanical system,electrical system and data acquisition system.A torque motor and a matched driving control system are employed to drive the machine directly,rather than the traditional DC motor-reducer drive system.Also,the new data acquisition system includes 90 static data channels and 38 dynamic data channels.The upgraded NHRI-400 g·t geotechnical centrifuge has been served in several projects and performed well.
