Injection molding machine energy-saving control cabinet Dr. Paul Smart Saver, is the introduction of cutting-edge German mature intelligent power control technology, combined with the world's most high-frequency technology features, and domestic application characteristics, we developed a series of new ideas high performance. Under the premise of improving the stability increases simple PLC, PID practical section, flexible input and output terminals, online parameters setting, self-identification signal transmission failures, power outages and downtime parameter storage, electrical energy control, traverse control, RS485 control, Fieldbus control and a series of practical operation of advanced control functions. Equipment manufacturers and end customers to provide highly integrated integrated solutions to reduce system acquisition and operating costs, improve system reliability is of great help. 1 Overview ?? in the plastics industry, injection molding machines, blow molding machines is the main production equipment, power consumption, while also very serious waste of electricity. How to reduce injection electromechanical energy consumption has become an important research topic in many plastics companies. Injection molding machine working process is divided into mold clamping, sol, injection plastic, Paul several stages, cooling, mold, ejector, etc., working pressure and flow needed for each stage are different, and there are some changes in the law . Hydraulic pump oil flow provided by the injection molding machine, the pressure is constant, but most of the time of the injection molding machine during operation are less than the actual pump flow and pressure constant flow and pressure. Excess hydraulic oil through the relief valve is returned to the storage tank, which not only caused the hydraulic oil temperature, and waste a lot of energy, particularly in the "cooling" This process is most serious. ? 2, the working principle of Dr. Paul-saving injection molding machine control cabinet for the technical characteristics of plastic industry injection molding machines, blow molding machines and other processing equipment, injection molding machine control flow and pressure variation signal acquisition, automatically adjusting the pump motor speed, and then adjust fuel supply amount, so that the actual amount of oil pump injection molding machine actual load in any work processes are consistent. Eliminate the overflow of hydraulic oil heat, thus making quantitative pump injection molding machine instead of the variable displacement pump, so that the injection molding machine without affecting the yield and quality of produce, both extending the life of the pipeline, but also saves the pump motor power consumption. ?? 3, Features l using frequency microcomputer control technology, without changing the existing injection molding machine control and the oil; l excellent soft start and soft stop function;?? L fault auto bypass, saving / bypass random switch; l save oil and cooling water consumption pump, pump and piping to extend life;?? l saving rate is high, so that the pump motor energy-saving rate of 20% -45%.
