Single Acting Pulse Width Control PLC Synchronous Hydraulic Lifting System 

Product Descriptions  

This system uses hydraulic driving, pressure and displacement closed-loop automatic control mode to realize multi-point control, widely used in replacement of highway bridge rubber bearings, overpass lifting, synchronous lifting of inland river bridge, equipment lifting and rectification etc.

System Composition and Main Principle 

This system is composed of 1 high pressure pump station, control valve groups, hydraulic cylinders, stroke monitoring devices, pressure monitoring devices and 1 set of electrical control system.

Hydraulic pump station controls the flow by on-off valve, depending on regulating the switch frequency to change the flow which achieves the purpose of output flow can be regulated continuously. Accurate control on the synchronization of each hydraulic cylinder in lifting and load balancing in weighing process can be achieved by matching with proper electric control device, to compose pressure and displacement closed-loop control.
