以闭式液压系统驱动压路机的振动器,当高速运转的偏心轴骤然停住时,会产生强烈的液压冲击。从而出现系统振动、噪声、漏油,甚至形成负压,发生吸空等现象。若缺少恰当的缓冲措施,将会导致系统不能正常工作。本文拟以具体实例,浅谈有关分析意见。一、噪声及漏油的原因图1为某振动压路机的振动系统液压原理图。柴油机驱动的双向变量泵与驱动振动器的双向定量马达组成一个闭式系统。即从油泵出
The vibrator of the roller is driven by a closed hydraulic system. When the high-speed eccentric shaft suddenly stops, it will generate a strong hydraulic shock. As a result, system vibration, noise, oil leakage, and even the formation of negative pressure, air suction and other phenomena occur. Without proper buffering measures, the system will not work properly. This article intends to use specific examples to discuss related opinions. First, the cause of noise and oil leakage Figure 1 shows the vibratory hydraulic system of a vibratory roller. A two-way variable displacement pump driven by a diesel engine and a two-way quantitative motor that drives a vibrator form a closed system. Ie pump out of the oil
