1. Run the fan curve can be described by a diagram of its saving principle: drawing, fan operation curve curve (1) for the fan at a constant rotational speed n1 of a wind pressure (HQ) characteristic curve (2) of the pipe network drag characteristics (throttle fully open). Curve (4) frequency operation characteristics (throttle fully open) if the fan is working at maximum efficiency point A, then the pressure of H2, air volume Q1, Shunde soil Wo Equipment fan shaft power N1 and Q1, proportional to the product of H2 In the figure represents the available area AH2OQ1. If the production process requirements, reduced air flow required from Q1 Q2, then use the damper method is equivalent to an increase pipe network resistance, so that the pipe network resistance characteristic curve is changed to (3), Soil Wo fan factory equipment, systems from the original work operating point A change to the new operating point B operation. It is seen from the figure, but increased pressure, shaft power is proportional to the area BH1OQ2. Obviously, the shaft power down much. If the drive speed control mode, the fan speed down the n1 n2, according to the proportion of the laws of the fan parameters, shown in the amount of wind speed n2 (QH) features such as curve (4). Meet the same case can be seen in the amount of wind Q2, a significant reduction in wind pressure H3, N3 with a significant reduction in power, soil Wo Equipment fans, represented by the area CH3OQ2. Power saving △ N = (H1-H3) × Q2, represented by the area BH1H3C. Obviously, the economic effect of energy saving is very clear. Routine maintenance proper maintenance, service, safety and reliability is the fan, important guarantee for improving the life of the fan. Therefore, when using the fan, we must draw sufficient attention. Impeller Maintenance: In the early impeller operation and regular inspection of all time, as long as there is an opportunity, you must check the impeller for cracks, wear, dust and other defects. Whenever possible, the impeller must be kept clean, and regularly go top with a wire brush the dust and rust leather, etc., because with longer running time, the dust since it is impossible to uniformly attached to the impeller, causing impeller balance destruction, as well as cause the rotor vibration. Impeller whenever a repair, it will need to further balancing. If the conditions, you can use the portable test instrument in the field balancing balance. Before making balancing, soil Wo Equipment fan prices, you must check all retaining screws tight. Because the impeller has been running for some time in the unbalanced state, the bolts may have loosened. Bearing Maintenance: Always check the bearing lubricant oil, if oil leakage box, you can put a little cap bolts tightened, that does not work, it may have to replace it with new packing up.
