我单位有台美国英格索兰ＳＤ１５０Ｄ振动碾，在新疆施工时出现激振力明显减小的现象（该设备才工作了 ２０３９ ｈ），故障的排除如下。 经与代理商共同分析认为，振动力减小的原因可能是由于液压油流量变小或压力变小，使振动马达形成的扭矩减小，从而导致偏心块的激振力减小 My unit has Taiwan and the United States Ingersoll Rand SD150D vibration grind, construction in Xinjiang appear significantly reduced the excitation force phenomenon (the device was working for 2039 h), troubleshooting is as follows. After analysis with the agents, the reason for the decrease of vibration force may be that the decrease of the hydraulic fluid flow or the decrease of the pressure make the vibration torque of the vibration motor decrease, which leads to the decrease of the excitation force of the eccentric block
