Description
Technical field
The utility model relates to injection machine energy-saving control device field, relates in particular to a kind of injection machine energy-saving intelligence controlling device.
Background technology
The injection machine industry be one with national product, the closely bound up industry of life, arrive automobile, mould greatly, all be unable to do without injection moulding to household electrical appliance, toy, mobile phone etc. and process for a short time, injection machine is the main production equipments of plastic cement industry.The energy consumption of injection machine mainly shows the power consumption aspect, includes: the power consumption of the power consumption of hydraulic system oil pump, the power consumption of heater and recirculated cooling water pump.Wherein, the power consumption of hydraulic oil pump accounts for the 65%-80% of whole injection machine power consumption, is the key of injection machine energy-saving.
The hydraulic injection molding machine system is pressure and all bigger load of flowed fluctuation, the different operating stage such as ejects in injection machine matched moulds, locked mode, injection, pressurize cooling, die sinking, and its pressure and flow all will take place clocklike to change.But in real work, the actual pressure of hydraulic injection molding machine system and the variation of actual flow are little when big when being, are almost equal to zero sometimes; And each course of work is respectively by the different different oil pump work of Oil pump electrical machinery control; At actual flow hour, the fuel delivery of oil pump is far longer than load actual consumption amount, and supply exceed demand; More than needed be in hydraulic oil under the high pressure conditions, thereby cause the severe energy waste problem all through the overflow valve overflow and emit great amount of heat energy.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of injection machine energy-saving intelligence controlling device, and this energy-saving intelligent control device has perfect civil power/economize on electricity translation function, and management is convenient in energy saving.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of injection machine energy-saving intelligence controlling device; Comprise external power source, switch unit, circuit controller, intelligent control unit and variable-frequency governor; Said switch unit comprises city's electric contactor and economize on electricity contactor; The input of said city electric contactor is selected the output of a conducting in said external power source with the input of economize on electricity contactor, and said circuit controller is electrically connected between the oil pump motor of output and injection machine of said city electric contactor; Said variable-frequency governor is electrically connected between the oil pump motor of output and injection machine of said economize on electricity contactor; Said intelligent control unit comprises detection module and s operation control module; Said detection module can detect running state information work such as (be die sinking, matched moulds, injection, feed back) ejecting of injection machine; And said running state information is transferred to said s operation control module, said s operation control module is analyzed and is calculated said running state information, and control command is transferred to said variable-frequency governor; Said variable-frequency governor is regulated the rotating speed and the torque of oil pump motor; Thereby make the actual fuel delivery of oil pump motor consistent, eliminate overflow phenomena, save electric energy with the traffic demand of injection machine.
Further improvement as the utility model also is provided with the capacitance compensation module, and said capacitance compensation module is electrically connected between said variable-frequency governor and the oil pump motor.
The beneficial effect of the utility model is: regulate and switch the power-saving running state and the civil power running status of injection machine automatically through utilizing handover module; Utilize intelligent control unit to detect the running state information of injection machine; And this running state information analyzed and calculate, control rotating speed and torque that variable-frequency governor is regulated oil pump then, thereby can make the actual fuel delivery of oil pump motor consistent with the traffic demand of injection machine; Eliminate overflow phenomena; Realize the effect of energy saving, and this energy-saving intelligent control device is convenient to regular maintenance, management, good reliability.
