Description
Technical field
The invention belongs to utilization and the control technique field thereof of ceramic brick press hydraulic power system, be specifically related to a kind of ceramic brick press energy-saving servo control system.
Background technique
As shown in Figure 1, existing ceramic brick press hydraulic power system generally adopts mair motor 1(threephase asynchronous machine) Host actuating pump 2; For protection main pump, usually can install an one-way valve 3 on the pressure export of main pump 2, the delivery pressure of main pump 2 is then regulated by relief valve 4.In addition, the pressure export of main pump is also connected to one in order to show the pressure gauge 5 of pressure, and main pump is connected with a solenoid directional control valve 6 for pressure release.
Although above-mentioned ceramic brick press hydraulic power system has been successfully applied on ceramic brick press, but there is following deficiency in this kind of hydraulic power system: in process of production, the time of ceramic brick press nearly 25 ~ 50% is for waiting for other aided process, and at this waiting time, ceramic brick press is in unloaded state, but because mair motor adopts threephase asynchronous machine, therefore mair motor still runs with rated speed Host actuating pump, thus causes the waste of the energy and cause hydraulic system temperature to raise.
Summary of the invention
The object of the present invention is to provide a kind of ceramic brick press energy-saving servo control system, to solve the deficiencies in the prior art part.
For achieving the above object, the present invention adopts following technological scheme:
A kind of ceramic brick press energy-saving servo control system, comprises main pump and the mair motor for Host actuating pump, and also comprises one for controlling pressure flow and the swinging angle control assembly of main pump.

Embodiment
As shown in Figure 2, a kind of ceramic brick press energy-saving servo control system of the present invention, on the basis of the existing ceramic brick press hydraulic power system shown in Fig. 1, adopt permanent magnet synchronous servo motor as mair motor 1, and increase by one for controlling pressure flow and the swinging angle control assembly of main pump.
Described pressure flow and swinging angle control assembly form primarily of pressure transducer 7, integrated manipulator 8 and servocontroller 9.Wherein, pressure transducer 7 is arranged on the pressure export of main pump 2, and is electrically connected with integrated manipulator 8.Integrated manipulator 8 is connected with the pressure export of main pump 2 and flowexit respectively, for detecting the delivery pressure of main pump, output flow and pivot angle in real time, and will detect real-time data transmission to servocontroller.Servocontroller 9 is connected with integrated manipulator and mair motor 1 respectively.
Working procedure of the present invention is as follows:
Pressure transducer detect main pump pressure export real-time delivery pressure and by data feedback to integrated manipulator.Difference between the force value that integrated manipulator foundation pressure transducer detects and the pilot pressure value of setting, computing and control is carried out according to the control algorithm preset, the pivot angle of adjustment main pump, the adjustment pivot angle of main pump and the output flow of adjustable main pump and input torque; The pressure data synchronous transfer that pressure transducer detects by integrated manipulator is to servocontroller, servocontroller carries out computing and control according to the control algorithm preset, the rotating speed of adjustment mair motor, the adjustment rotating speed of mair motor and the output flow of adjustable main pump.According to actual process needs, the pivot angle of main pump and the rotating speed of mair motor can adjust simultaneously, also can carry out respectively, and the output torque of mair motor, output voltage and output current also respective change.Pilot pressure can according to the multistage setting of the technological requirement of reality, integrated manipulator and servocontroller coupling mair motor rotating speed and output torque, main pump delivery pressure and output flow etc., the rotating speed of the pivot angle of main pump and mair motor can be regulated automatically according to the control algorithm of the technological requirement of reality according to setting, make mair motor input power meet usage requirement, avoid extra waste.In addition, in the unloaded state, the pivot angle of main pump is minimum, and mair motor rotating speed, output torque, output voltage and output current are minimum, that is mair motor input power is minimum, realizes energy-saving effect to greatest extent.
