Ping An Electric developed a new generation of fans

Xiangtan Pingan Electric Group Co., Ltd. has recently designed and developed a curved and swept combination orthogonal type explosion-proof counter-rotating axial flow main ventilator to promote the replacement of main ventilators. Its design theory and method are currently The first in China.

The design of this series of fans is based on the modern theory of centralized parameter optimal control theory, distributed parameter optimal control theory, numerical simulation of full three-dimensional turbulent flow field, and the minimum flow loss and aerodynamic noise. A multi-parameter control such as grazing, a method of comprehensive aerodynamic and structural optimization design using a computer. The technical key is to control and ensure that the fan airflow direction is perpendicular to the axial section of the fan to minimize the pressure loss and aerodynamic noise of the airflow by combining the most reasonable combination of the front and rear bending and the left and right bending.

The ventilator designed and produced by this theory and method has high efficiency and low noise. Compared with similar products at home and abroad, its rated efficiency is increased by 5% to 10%, and the actual operating efficiency is increased by 35%. The use of this theory and method has designed and produced more than one thousand types of wind turbines, saving energy consumption, improving environmental conditions, and improving economic efficiency. At present, the curved and swept combination orthogonal three-dimensional twisted blade technology is only used for mine main ventilators, and Xiangtan Pingan Electric Group Co., Ltd. will apply it to mine local ventilators and other fields within two years. According to reports, this technology is advanced, mature, competitive, and has a broad market prospect.
