Double Acting Frequency Conversion Control PLC Synchronous Hydraulic Lifting System
Double Acting Frequency Conversion 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 heavy load weighing, synchronous pushing, synchronous lifting, synchronous lowering, equal proportion lifting, attitude leveling and automatic voltage regulation etc.
Pump motor is controlled by frequency conversion speed regulator, depending on adjusting the frequency of the power supply to change the motor speed, which achieves the purpose of output flow can be regulated continuously. Accurate control on lifting speed to realize synchronous control of cylinders can be achieved by matching with proper electric control device and monitoring device.
System Composition (Four points frequency conversion system as an example)
This system is composed of 4 pumps, 4 sets of frequency conversion speed control devices, 4 sets of control valve groups, electric control system and stroke sensors.
