Detailed Product Description: | [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fan] fan noise detection and fan vibration detection: the main basis GB / T 2888-2008 "fan and blower noise measurement method", JB / T 8690 -1998 "Industrial Fan noise limits", JB / T 8689-1998 "fan vibration detection and restrictions", GB 9068-1988 "heating, ventilation and air-conditioning equipment - Determination of sound power - Engineering method", GB / "Determination of sound power levels of noise sources reflecting plane free field sound pressure - Engineering method" T 3767-1996. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fan] fan impeller is the main component wind turbine technology, its geometry, size, number of leaves and manufacture of precision have a significant impact on performance. Static balance impeller or fan balancing correction in order to ensure smooth rotation. The export orientation of different blade impeller into forward, radial and backward three types. Front tilt toward the top of the impeller vanes of the impeller rotation direction; top blade radial impeller is in the radial direction, is divided straight blade and curved blade; after rotating reverse tilt toward the top of the impeller vanes of the impeller. In contrast to the impeller efficiency after pressure, the resulting minimum, desired maximum impeller diameter, and; before the maximum pressure generated by the impeller fan heater, and the flow rate at a certain number of revolutions, the required minimum diameter of the impeller fan, but the efficiency is generally low generally higher; radial impellers in between. Vane-type lines straight blade simplest and most complex airfoil blades. In order to have the right blade surface velocity distribution, generally using curved blades, such as blades, such as the thickness of the arc. Impeller cover discs usually have to increase the strength of the impeller and reduce gas leakage between the blade and the casing. Coupling the blade with the cover plate by welding or riveting. Lighter weight impeller welding, smooth flow. Low, medium small centrifugal fan impeller is also made of aluminum alloy casting. When the axial fan work, power machine driven fire exhaust fan impeller rotates within a cylindrical enclosure, gas enters from the collector to obtain energy through the impeller, increasing the pressure and speed, and then discharged in the axial direction. Arrangement of the axial fan has a vertical, horizontal and inclined three, small, only about 100 mm impeller diameter, large up to 20 meters. Wind turbine technology, Tianjin Jinzhong Ji ventilation engineering company (certified), provided by the Tianjin Tianjin Jinzhong Ji HVAC blower purification equipment. Tianjin Jinzhong Ji HVAC purification equipment Limited (www.Jzjnt.com) is a leader in Tianjin, 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. In the group leadership with the staff warmly welcome all inquiries negotiations to create a better future for the base. |
