摘要
针对超高层混凝土泵送液压系统中的压力冲击问题,论文提出了一种基于可变排量机油泵、蓄能器和智能控制系统的压力冲击控制技术。通过接近开关与阻尼缓冲器等装置,优化了传统系统中换向阀突变引发压力波动的问题。该系统实现了±0.6MPa的低压力波动,响应时间缩短至23 ms,稳定时间减少了60.0%。
Aiming at the pressure shock problem in the hydraulic pumping system of super high-rise concrete,this paper proposes a pressure shock control technology based on variable displacement oil pumps,accumulators and intelligent control systems.The problem of pressure fluctuations caused by sudden changes in the directional control valve in traditional systems has been optimized through devices such as proximity switches and damping buffers.This system achieves a low pressure fluctuation of±0.6 MPa,shortens the response time to 23 ms,and reduces the stabilization time by 60.0%.
