ESC1000B basket speed control speed control board to explain the principles of the two aspects: the saving principle is to replace the fan pump Windshield or throttle control air flow with speed control, which is an effective way of saving. Windshield panels with rated air flow control Q1 = 100% output, the shaft power is proportional to N1 and area AH1 OQ1, if the wind halved Q2 = 50% output governor ESD5111, the shaft power into N2 and area BH2 OQ2 proportional reduction than N1 much, it is because of the need to overcome the windshield board pressure due to increased resistance. If the same amount of wind speed control output by half, the number of revolutions dropped by n1 n2, parameter scaling law drawn by the fan characteristic curve when n2, C point for the new mining point, then the shaft power into N2 and area CH3OQ2 proportional, in the case of Q2 meet the same amount of wind, a lot of functions to reduce the shaft, saving power consumption is proportional to the area of ??△ N and BH2H3C seen saving effect is very significant. DGC2007 Daewoo factory speed control board since its inception, adhere to the "people-oriented, customer satisfaction governor ESD5500, quality, excellence" for the system policy governor US59002, within the company continued to strengthen quality management, the establishment of a more perfect modern enterprise management system.
