Abstract
A kind of novel pressure control system, including：Oil cylinder, control valve, safety valve, servo oil pump, servo controller, pressure sensor, signal exchange device, industrial computer；The oil cylinder connects control valve, control valve connection safety valve；Pressure signal is passed to signal exchange device by the pressure sensor output end by signal wire；The signal exchange device is connected by data wire with industrial computer；The signal exchange device connects servo controller, servo controller connection servo oil pump.The utility model global design is reasonable, and pressure controling precision is high, keeps pressure constant for a long time, and no pressure drop does not need ftercompction, can realize Curves Pressure control.
Description
Technical field
The utility model belongs to mechanical field, and in particular to a kind of novel pressure control system.
Background technology
At present, the control pressurer system of most of hot press, it is to have pressure regulator valve control pressure, check valve pressurize, falls to be pressed onto
Ftercompction again during certain value, pressure oscillation is big, does not meet actual operation requirements.
Utility model content
Purpose of utility model：The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of structure
Rationally, pressure controling precision is high, keeps pressure constant for a long time, and no pressure drop does not need ftercompction, can realize Curves Pressure control
The novel pressure control system of system.
Technical scheme：In order to solve the above-mentioned technical problem, a kind of novel pressure control system described in the utility model, bag
Include：Oil cylinder, control valve, safety valve, servo oil pump, servo controller, pressure sensor, signal exchange device, industrial computer；It is described
Oil cylinder connects control valve, control valve connection safety valve；Pressure signal is passed through signal wire transmission by the pressure sensor output end
Give signal exchange device；The signal exchange device is connected by data wire with industrial computer；The signal exchange device connects servo control
Device processed, servo controller connection servo oil pump.
Further, can need to input and preserve pressure parameter according to technique on the industrial computer.
Further, when the industrial computer temporally sends different pressure signals, system pressure is forming curves control.
Further, current pressure values are communicated database storage to industrial computer by servo controller, and industrial computer can be with
Show work at present pressure and consult and export history operating pressure record, output numerical value can be that form can also be curve.
Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model global design is closed
Reason, pressure controling precision is high, keeps pressure constant for a long time, and no pressure drop does not need ftercompction, can realize Curves Pressure control.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Embodiment 1：A kind of novel pressure control system, including：Oil cylinder 1, control valve 2, safety valve 3, servo oil pump 4, watch
Take controller 5, pressure sensor 6, signal exchange device 7, industrial computer 8；The oil cylinder 1 connects control valve 2, and control valve 2 connects
Safety valve 3；Pressure signal is passed to signal exchange device 7 by the output end of pressure sensor 6 by signal wire；The signal is handed over
Parallel operation 7 is connected by data wire and industrial computer 8；The signal exchange device 7 connects servo controller 5, and servo controller 5 connects
Servo oil pump 4.
It can need to input and preserve pressure parameter according to technique on the industrial computer.
When the industrial computer temporally sends different pressure signals, system pressure is forming curves control.
Specific implementation：The action of the oil cylinder is controlled by control valve, and control valve connection safety valve is pressure protection；
Pressure signal is passed to servo controller by the pressure sensor by signal wire；The servo controller by data wire and
Industrial computer connects and forms communication；Current pressure signal is passed to servo controller, servo controller by the industrial computer
The real-time pressure arrived according to current pressure signal and pressure sensor monitoring, moment of torsion and rotating speed at that time are calculated, passes through cable
The pressure and flow of servo oil pump are controlled, system pressure is maintained in the pressure limit of technological requirement.
