Problems solved by technology

The hydraulic synchronization methods include the use of mechanical synchronization, the use of hydraulic synchronization valve synchronization, the use of throttle valves, speed control valve hydraulic synchronization, and the use of gear shunt motor synchronization. The above synchronization methods all share a common feature, that is, they all belong to the open-loop control system , can be used for short-stroke hydraulic cylinders or systems that require low synchronization accuracy, but cannot be achieved when high synchronization accuracy and long-stroke hydraulic cylinders are required

Abstract

The invention relates to a hydraulic servo synchronization system. The hydraulic servo synchronization system comprises an oil tank, an auxiliary unit and a reversing valve, wherein the oil tank is used for storing oil liquid; the auxiliary unit is provided with an auxiliary oil way for conveying oil liquid; the reversing valve is provided with a first oil way and a second oil way which are connected with each other in parallel; the reversing valve is used for reversing; the first oil way, the second oil way and the reversing valve are communicated with the auxiliary oil way. Through the hydraulic servo synchronization system, a main unit and the auxiliary unit are used for achieving the synchronization purpose jointly, so that the hydraulic servo synchronization system is accurate in operation and rapid in response; the operating efficiency is improved.

Description

technical field [0001] The invention relates to the field of electromechanical hydraulics, in particular to a hydraulic servo synchronization system. Background technique [0002] The hydraulic synchronization system is to realize the circuit in which multiple actuators move with the same displacement, the same force or the same speed. Due to the large load or the layout of large-scale equipment, multiple hydraulic actuators need to be installed to drive one actuator at the same time, such as the compression hydraulic cylinder in the hydraulic press, the body lifting hydraulic cylinder in the pile driver, and the boom cylinder in the loader. And bucket cylinders, bucket door hydraulic cylinders and bucket lift cylinders in scrapers, blade lift cylinders and ripper lift cylinders in bulldozers, boom cylinders, bucket cylinders and stick cylinders in excavators, etc. [0003] Hydraulic synchronous motion includes force synchronous, velocity synchronous and position synchronou...
