Dezhou Plumper ventilation plant is specialized in the production of central air-conditioning equipment manufacturers supporting the end. Product totally GB, standard production line, advanced equipment axial fan brand, technology and stable according to. Our main domestic large enterprises do OEM OEM production. Energy works when the impeller rotates, the axial gas from the inlet into the impeller, the impeller blades push by leaving the gas is raised, and then flows into the wicket. Vanes will deflect the airflow into the axial flow, while the gas is introduced into the diffuser tube, and further gas kinetic energy is converted to pressure energy exhaust axial fan manufacturers, introduced last working lines. Six proportional to the total noise level of the fan blade speed. According to the analysis, the fan noise source is basically a dipole nature. Further to the introduction of Hebei axial fan supplier, the noise is due to the effect on the blades on the fan air flow through the veins caused power. Fans may think there are two discrete frequency noise source, a field with the pressure caused by the movement of the rotor blade propeller noise, and the other is powered leaf veins aerodynamic noise caused by interference. Wind maneuver, quiet distance between the blades is an important factor interference noise. Axial fans brand, 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.
