Description
Technical field
The utility model relates to a kind of hydraulic press hydraulic power control gear, is specifically related to one and is mainly used in ceramic brick press hydraulic power Servocontrol device.
Background technique
As shown in Figure 1, the hydraulic power system of existing part ceramic brick press adopts driven by servomotor metering pump, and its working principle is: main pump 3 is a metering pump, adopts actuating motor 2 to drive, rotating speed is controlled by servocontroller 1, adopts rotary transformer 4 to detect rotating speed.For protection main pump, the pressure export of main pump is installed an one-way valve 5.The pressure export of main pump has connect a pressure gauge 6 to show pressure, is connected to a pressure transducer 7 to detect the delivery pressure of main pump simultaneously.Difference between the pressure detected according to pressure transducer 7 and setting pressure, servocontroller 1 controls the rotating speed of actuating motor 2 according to predetermined pid algorithm.When the pressure that pressure transducer 7 detects reaches setting pressure, the rotating speed of actuating motor reduces; When the pressure that pressure transducer 7 detects is lower than setting pressure, the rotating speed of actuating motor raises.Although this control gear can reduce the energy consumption of ceramic brick press, because quantitative pump delivery is less, the ceramic brick press of little tonnage can only be used for, and can not be generalized on medium-sized and large size ceramic brick machine and use.In addition, also there is another one shortcoming in this kind of control gear, namely when the frequency of okperation of ceramic brick press is lower, ceramic brick press waits for that the time of other aided processes is longer, interior actuating motor stops operating completely during this period of time, until actuating motor and main pump just start again when ceramic brick press starts to suppress, this just causes actuating motor and main pump Fraquent start and stopping, electric current when actuating motor starts is large, the energy loss caused because braking during stopping is large, cause the temperature rise of actuating motor large, power saving rate reduces, and also reduces the working life of actuating motor; Further, main pump starts frequently and stops also reducing the working life of main pump.
Model utility content
The purpose of this utility model is to provide a kind of ceramic brick press hydraulic power Servocontrol device, effectively to solve the deficiencies in the prior art part.
For achieving the above object, the utility model adopts following technological scheme:
Ceramic brick press hydraulic power Servocontrol device, the main pump comprising servocontroller, the actuating motor be connected with servocontroller and be connected with actuating motor, the pressure export of described main pump connects an one-way valve; Described actuating motor is permanent magnet synchronous servo motor; And described main pump is variable displacement pump, and be connected with a relief valve for regulation output pressure and the solenoid directional control valve for pressure release respectively.
Further, described actuating motor is connected with described servocontroller by a rotary transformer.
Further, the pressure export of described main pump is provided with a pressure transducer, and described pressure transducer is connected with described servocontroller.
Further, the pressure export of described main pump pressure is provided with a pressure gauge.
The utility model, by adopting said structure, the rotating speed of mair motor can be regulated according to actual pressing process, and the flow of main pump also can export according to the hydraulic system demand of reality, thus realizes the energy-conservation of ceramic brick press; Meanwhile, because ceramic brick press energy consumption reduces, cause oil temperature in hydraulic system also to reduce, and then extend the working life of hydraulic element, also reduce the use amount of cooling medium.

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Embodiment
As shown in Figure 2, ceramic brick press hydraulic power Servocontrol device described in the utility model, forms primarily of servocontroller 1, actuating motor 2, main pump 3, rotary transformer 4, one-way valve 5, pressure gauge 6, pressure transducer 7, relief valve 8 and solenoid directional control valve 9.Actuating motor 2 is permanent magnet synchronous servo motor, is connected with servocontroller 1 by rotary transformer 4.Main pump 3 is variable displacement pump, is connected with actuating motor 2.One-way valve 5, pressure gauge 6 and pressure transducer 7 are separately positioned on the pressure export place of main pump 3.Pressure transducer 7 is connected with servocontroller 1.Relief valve 8 is connected with main pump 3 respectively with solenoid directional control valve 9.
Working procedure of the present utility model is as follows:
The rotating speed of actuating motor is controlled by servocontroller, and adopt rotary transformer to detect rotating speed, main pump adopts variable displacement pump, limits its maximum service pressure by relief valve.The pressure export of main pump connects pressure gauge to show pressure.The pressure export of main pump connects pressure transducer, the difference between the pressure detected according to pressure transducer and setting pressure, and servocontroller controls the rotating speed of actuating motor according to predetermined pid algorithm, thus automatically regulates the output flow of main pump.When ceramic brick press waits for aided process, limit the minimum speed (being generally 200r/min) of actuating motor, avoid the low velocity zone of actuating motor, response when actuating motor both can have been made to accelerate is very fast, improve the response of ceramic brick press hydraulic system, additionally reduce energy ezpenditure during actuating motor brake, so not only the temperature rise of actuating motor is lower, the power saving rate of system also increases, and can also reduce the damage of main pump.When ceramic brick press wait aided process, actuating motor are in low velocity zone, are shed the delivery pressure of main pump by solenoid directional control valve, reduce the output torque of actuating motor, thus reduce the input current of actuating motor.In the unloaded state, the delivery pressure of main pump is minimum, and actuating motor rotating speed, moment of torsion and electric current are minimum, that is the input power of actuating motor is minimum, realizes energy-saving effect to greatest extent.
