Detailed Product Description: | Foshan axial fans, air conditioning, Shandong Xiang sails (certified), axial fans are provided by the Texas Xiang sails central air-conditioning parts plant. Texas Xiang sails central air-conditioning parts plant (www.dztfsb.com) is specialized in the "fans, dampers, duct, aluminum outlet" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Liu. Optimize the design and performance prediction of fan establish the mathematical model of the merits of the results has a critical influence. Currently Henan axial fans, a description of the overall loss of fan-based mathematical model to analyze the loss of more than runner may appear with a simple formula to express the relationship between the flow field and lost, and then the loss of superposition, this calculated performance. This method is too dependent on relevant experience factor, and wide ranges of these coefficients can not be reasonably selected according to the specific form of the flow channel, while ignoring the mutual influence and interaction between the loss and therefore the actual situation quite different. Normal operation phase voltage axial fans, Dongguan, power system symmetrical three-phase induction electromotive force of the third coil and zero. Once the single-phase ground, the neutral point displacement occurs between terminals open triangle will appear zero-sequence voltage relay action, and thus the power system protection. Zero-sequence voltage coil appears the corresponding iron hearts will be zero sequence flux. To this end, Changchun axial fan, this three-phase voltage transformer cores using next Yoke or using three single-phase voltage transformer. For less demanding accuracy of this transformer, the third coil, but it requires a certain amount of over-excitation properties. |
