随着液压技术应用范围的扩大,要求两个或两个以上的液压缸或液压马达同步运动的场合也越来越多。实现同步运动的方法虽然很多,但到目前为止还未能得到较为理想的同步方法,因其受负载、泄漏、制造精度、调整等多因素的影响。下面就单独采用调速阀同步回路进行分析,找出影响同步精度的因素及其解决方法。 With the expansion of the application range of hydraulic technology, there are more and more occasions where two or more hydraulic cylinders or hydraulic motors are required to move synchronously. Although there are many methods to realize synchronous motion, so far, it has not been able to obtain the ideal synchronous method, which is affected by many factors such as load, leakage, manufacturing precision and adjustment. The following separate control valve speed loop analysis, identify the factors that affect the synchronization accuracy and its solution.
