Dezhou Plumper ventilation plant is specialized in the production of central air-conditioning equipment manufacturers supporting the end. Products in full accordance with the national standard, standard production line heat axial fans, advanced equipment, technology and stable cross-section axial fans generally airfoil. Vane axial fans may be a fixed position of high temperature, may be about its longitudinal axis. Blades and the blade pitch angle or the air flow may be adjustable or not adjustable. Changing the blade angle or pitch is one of the main advantages of axial fan. Small blade pitch angles produce lower flow Xinjiang electric axial fans, and increase the spacing may result in higher traffic. When moving, the distance between the vanes increases, while reducing the impact of the bit stream interference effects than the speed of change in the wake of faster blade acts as a sound barrier also decreases with increasing distance. Thus, at least three parameters that affect the size of the interference noise: blade shape velocity waveform (ie blade loading), leaf blades radiating surface distance between the columns and as a sound source. Very small pitch may have two acoustic impact. If the vanes on the rotor blades interference field force established to make the rotor blades into a pulsating sound source, while the leaves are still sound barrier. Xinjiang electric axial fan, rich ventilation equipment (certified), axial fans are provided by Shandong Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (#) is a leader in Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Rich ventilation equipment in leadership with the staff warmly welcome all inquiries negotiations to create rich, ventilation a better future.
