所谓液压冲击,就是机器在突然启动、停机、变速或换向时,由于流动液体和运动部件惯性的作用,使系统内瞬时出现很高的压力。液压冲击不仅影响液压系统的性能稳定性和工作可靠性,还会引起振动和噪声以及连接件松动等现象,甚至使管路破裂、液压元件和测量仪表损坏,在高压、大流量的系统中其后果更为严重。因此,预防液压冲击很重要。
The so-called hydraulic impact, that is, the machine suddenly start, stop, speed change or commutation, due to the inertia of the flow of liquid and moving parts, the system instantaneous high pressure. Hydraulic impact not only affects the performance of the hydraulic system stability and reliability, but also lead to vibration and noise, as well as loose connections and other phenomena, and even rupture of the pipeline, hydraulic components and measuring instruments damage, high pressure, high flow system The consequences are even more serious. Therefore, it is important to prevent hydraulic shocks.
