Key words: aluminum; anodizing; power efficiency
The oxidizing power source is an important equipment in the anodizing process of aluminum profiles, and also the main power consuming equipment in the oxidizing electrophoresis workshop. In recent years, with the emphasis on energy saving and clean production, many aluminum profiles have gradually begun to use more energy-saving and environmentally-friendly oxidation. Frequency switching power supply, an aluminum profile factory trials a high-frequency silicon machine with a rated power of 600Kw. This paper analyzes the actual power consumption of the model and analyzes the efficiency and unit film of the high-frequency silicon machine and ordinary silicon machine. The power consumption of the volume and the power saving law of the high frequency silicon machine.
Raw data record and calculation section
Part of the recorded data includes: silicon machine number; bath temperature (measured oxidation bath temperature); film thickness; area; current density; set current, time (calculated by the formula δ = kit, k = 0.3); output current, output voltage ( Oxidation power supply control system display); initial number of electricity meters, number of final electricity meters (silicon electromechanical scale).
Calculate part of the data including: power consumption = number of final meters - initial number of meters; actual power consumption = power consumption × magnification (silicon oxide machine rate = 200); theoretical power consumption = output current × output voltage × time (definition theoretical consumption Electricity is the useful work for current, non-pure resistance circuit useful work W = UIt); efficiency = theoretical power consumption ÷ actual power consumption (η = W useful work / W total work); membrane volume = film thickness × area; Membrane volume power consumption = actual power consumption / membrane volume.
