The invention discloses a control method of a synchronous hydraulic system, a counterweight synchronous hydraulic system and a crane. The control method of the synchronous hydraulic system comprises the steps that the first displacement D1 of a first oil cylinder is obtained; acquiring a second displacement D2 of a second oil cylinder; and the difference value delta between the first displacement D1 and the second displacement D2 is calculated, and the oil supply amount of the first oil cylinder and/or the second oil cylinder is adjusted according to the difference value delta. The response speed is high, the first displacement D1 and the second displacement D2 are detected in real time, the difference delta difference between the first displacement D1 and the second displacement D2 is compared, the speeds of the first displacement D1 and the second displacement D2 are in dynamic adjustment all the time, it is guaranteed that the first displacement D1 and the second displacement D2 are flush, and synchronization precision is high; and the problem of asynchronous telescopic displacement of the two oil cylinders caused by left-right imbalance of the balancing weight is also avoided.
本申请公开了一种同步液压系统的控制方法、配重同步液压系统及起重机;其中同步液压系统的控制方法包括:获取第一油缸的第一位移D1;获取第二油缸的第二位移D2;计算第一位移D1与第二位移D2的差值为Δ差,并根据差值Δ差调节第一油缸和/或第二油缸的供油量。本申请响应速度快,通过实时检测第一位移D1和第二位移D2,并比较两者差值Δ差,进而使两者的速度始终处于动态调整中,进而保证第一位移D1和第二位移D2持平,其不仅同步精度高,还避免了因配重块左右不平衡导致两油缸伸缩位移不同步的问题。
