1.Overview:
The system uses hydraulic drive, pressure and displacement closed-loop automatic control mode,
multi-point control can be overloaded weighed push synchronization, synchronous lifting,
synchronous landed proportional synchronous lifting, posture leveling, automatic voltage regulator
other functions.
System uses a variable speed pump motor control, relying on the frequency regulation power to
change the motor speed, the pump flow rate to achieve the purpose of continuously adjustable,
with appropriate electronic control and detection systems, we can precisely control the
acceleration and deceleration jack , to achieve synchronization control jack.
2.Second, the system consists of:
The system is composed of six pumps, hydraulic jacks, six sets of frequency control devices, six
sets of control valves, electronic control system and displacement sensors and other components.
3.Third, the principle outlined:
Underside of the workpiece is not necessarily flat, in order to ensure consistent load jack, jack up
the workpiece in sync before the first contact with the workpiece to make jack uniform and uniform
contact with the workpiece jack that jack synchronous operation as a reference, for the system
There is a fitting function. Synchronous Lifting before starting its function, jack up the same time,
once a top contact with the workpiece, the top will stop rising until it contacts the workpiece until
the whole of the roof, and then stepped up to the top evenly around each top 5MPa (available in
the interface design given pressure fitting), then automatically stops the top, and the zero point
position as a synchronization.
Six sets of the system, the displacement detecting device is mounted on a suitable control point
position when the hydraulic cylinder is moved, the displacement sensor can be measured
accurately in real time displacement of the hydraulic cylinder. In hydraulic oil inlet, the system is
also equipped with a pressure sensor, relying on hydraulic cylinders which can determine the load.
Also equipped with a balancing valve, the valve can guarantee when you are in a hydraulic lift into
the oil state governor, while holding pressure balance valve can reliably ensure that the workpiece
will not free fall, the hydraulic cylinders in the power state still reliable hosting. This system is
suitable for large tonnage long stroke cylinder, which is characterized by jacking speed.
4.Hydraulic Schematic
The electronic control system is the synchronized movement of the key. It is based on closed-loop
control system theory, moving heavy objects displacement signal as controlled parameter, the
weight force of the hydraulic jack cavity pressure signal as generated by the reference amount.
These signals are collected by sensors, the signals transmitted to the controller. The controller to
receive and process these signals. Controller compares the operation of these same signals and
input tolerance value, when the discovery of a controlled point there is the possibility of tolerance,
the controller sends signals to the point of the inverter operation, turn off the hydraulic pump
