Description
[technical field]
The utility model relates to a kind of energy saver, relates in particular to the energy saver on a kind of injection machine.
[background technology]
The present injection machine that uses aborning, hydraulic system power all adopts the Induction Motor-Driven oil pump to provide.Because injection machine is in each cycle of injection moulding, under difference action, different process, required flow, the pressure of load is also different.But because the running speed of asynchronous machine is certain, in order to reduce the loss of energy, the hydraulic system that has has adopted variable pump, makes its difference according to operating mode adjust pressure and flow, thereby saves energy, plays energy-conservation effect.
Asynchronous machine is under the certain situation of voltage, magnetic flux is changeless, variable pump can change the load of motor, but when the injection machine actual loading hour, the power output of motor still is far longer than the power of load consumption, this moment, motor was in the low load with strong power phenomenon, make the copper cash winding produce excessive magnetic flux, cause electric efficiency to descend, cause the waste of energy, even so adopt the hydraulic system of variable pump, also can cause loss when under some operating mode, moving, can not really reach purpose of energy saving than macro-energy.
[utility model content]
The purpose of this utility model is to be to overcome the deficiencies in the prior art, provide a kind of and can regulate the energy saver that is used for injection machine of motor power output in real time according to the load size, it has real energy-saving and cost-reducing advantage, meets the demand of the energy-conserving and environment-protective of current society.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of energy conservation apparatus of plastic jetting-moulding machine, it includes energy-saving control system, described energy-saving control system comprises monitoring modular, s operation control module and Executive Module, wherein monitoring modular is connected with the s operation control module, the s operation control module is connected with Executive Module, meanwhile the input of Executive Module inserts civil power, and output is connected with the injection machine Oil pump electrical machinery by behind the detection module.
In the improvement project to above-mentioned energy conservation apparatus of plastic jetting-moulding machine, described energy-saving control system is arranged in the cabinet.
Compared with prior art, the beneficial effects of the utility model are: owing to be provided with energy-saving control system at the feeder ear of Oil pump electrical machinery, it comprises monitoring modular, s operation control module and Executive Module, wherein monitoring modular is connected with the s operation control module, the s operation control module is connected with Executive Module, meanwhile the input of Executive Module inserts civil power, output is connected with the injection machine Oil pump electrical machinery by behind the detection module, under the situation of underloading, will supply with the voltage of injection machine Oil pump electrical machinery and reduce to Minimum requirements automatically, and the rotating speed maintenance is constant, reduce the stator excitation electric current of motor, make supply line's loss, the copper loss of motor winding significantly reduces, the iron loss of motor descends, and avoids the waste of energy of motor, has improved efficiency of motor; And when load increases, voltage can rise automatically in moment, the power output of motor is just mated with instant load, thereby minimizing copper loss, iron loss, improve the starting performance of motor, the utility model can be accomplished, along with the variation of injection machine Oil pump electrical machinery load, under the condition that does not change motor speed, the input voltage of motor is adjusted in Self Adaptive Control, the instant load of motor power output and injection machine is complementary, make the corresponding raising of motor operate power factor, lower the magnetic flux of motor simultaneously, thereby reduce the power attenuation of motor, reach purpose of energy saving, meet the demand of the energy-conserving and environment-protective of current society.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
[description of drawings]
Fig. 1 is a circuit block diagram of the present utility model.
[specific embodiment]
The utility model is a kind of energy conservation apparatus of plastic jetting-moulding machine, comprise cabinet (not drawing among the figure) and be located at the interior energy-saving control system of cabinet, wherein energy-saving control system comprises monitoring modular 1, s operation control module 2 and Executive Module 3, monitoring modular 1 is connected with s operation control module 2, s operation control module 2 is connected with Executive Module 3, meanwhile the input of Executive Module 3 inserts civil power, and output is connected with injection machine Oil pump electrical machinery 4 by monitoring modular 1 back.
In use, the variation at the phase angle between the voltage and current of injection machine Oil pump electrical machinery 4 is defeated by in monitoring modular 1 real-time tracking, monitoring, this phase angle is constantly to change with the load variations of motor, send the information that monitors to calculation process module 2 simultaneously, calculation process module 2 is according to detection signal, after using special Algorithm Analysis, processing, execution command is sent to the voltage that Executive Module 3 is adjusted injection machine Oil pump electrical machinery 4 in real time.Under the situation of underloading, will supply with the voltage of injection machine Oil pump electrical machinery and reduce to Minimum requirements automatically, and the rotating speed maintenance is constant, reduce the stator excitation electric current of motor, make the copper loss of supply line's loss, motor winding significantly reduce, the iron loss of motor descends, avoid the waste of energy of motor, improved efficiency of motor.If when load increases, voltage can rise automatically in moment, the power output of motor and instant load is just mated, thereby reduce copper loss, iron loss, improved the starting performance of motor.The utility model can be accomplished, variation along with the load of injection machine Oil pump electrical machinery, under the condition that does not change motor speed, the input voltage of motor is adjusted in Self Adaptive Control, the instant load of motor power output and injection machine is complementary, makes the corresponding raising of motor operate power factor, lower the magnetic flux of motor simultaneously, thereby reduce the power attenuation of motor, reach purpose of energy saving.
The utility model is arranged on energy-saving control system in the cabinet, its installation like this, safeguards all very conveniently, as long as plug civil power when mounted, and its corresponding interface is connected with Oil pump electrical machinery gets final product.
