Single Acting Pulse Width Control PLC Synchronous
Hydraulic Lifting System SOV SMTB Series
Description:
This system is hydraulic driven and automatically controlled by pressure and displacement closed-loop, the system is widely applied in rubber support replacement of expressway , lifting of flyovers and river bridges, rectification of heavy equipment.
The components and principle of the system:
This system was composed by high pressure hydraulic pump, hydraulic control Valve Group, hydraulic cylinders, displacement detection devices, pressure detection devices, one set electrical control system.
The flow of the pump in this system is controlled by changing the the switch frequency of the on-off valve, that means the output flow of pump was adjustable. And equipped with the suitable electric control devices to form the pressure and displacement closed-loop. Then, every cylinder can be precisely controlled to achieve synchronous lifting and keep balanced load when in weighting process.
Specification:
Displacement Precision≤±0.2mm
Working Voltage:AC380V/50Hz(Three-phase-Five-wire system)
Max Pressure:700bar
Control Pattern:PWM(Pulse Width Modulation)
Operation Interface:Human-Computer
Alarm device: Alarm running light
Equipped with supper low height cylinders, Been applied in rubber support replacement of expressway
Structure description:
The plunger pump is used in this system, with the two-way shut-off valve in this pump, that can make sure cylinders in oil feeding speed control situation both in lifting and declining process, and relieve the influence the hydraulic impact on the synchronization accuracy when the cylinders in lifting switch process. Same times, the balance valve can lock the cylinders without leakage, that can make sure the cylinders wouldn't decline and the load wouldn't lose control when unexpected power failure happened. There are pressure transmitter detection devices and displacement detection devices in this system. When the cylinders being moved, the pressure detection devices can accurately measure the load on cylinders in real-time, the displacement detection devices can measure the cylinders' displacement in real-time.
The features of electrical control system is the controller made up of Siemens PLC, the pressure sensor and displacement sensor of each cylinder pass the the signal to PLC for monitor. The valve groups are driven and the hydraulic oil were output to hydraulic cylinders to make them lifting according to the order from the main console. PLC keep correcting the displacement error and load balance by the value of pressure and displacement.
