Hebei Teng Hao Fan Manufacturing Co., Ltd. production and processing all types of boiler blower, model complete, reliable quality. Application of Boiler Fan widely used in ventilation electricity, factories, mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the air; air-conditioning equipment and household appliances equipment cooling and ventilation; grain drying and should select; wind tunnel inflatable air source and hovercraft and propulsion. Y4-68 Boiler draft fan mainly by the impeller, housing, air inlet, adjust the doors and transmission sets. Impeller: 12 backward from the wing blade welded to the arc cone wheel cover and intermediate plate **. Induced draft fan impeller blade head with a solid body and wear resistant materials increase welding unit, to improve the life of the blade. Impellers have been static and dynamic balance test, to ensure smooth operation. Chassis: chassis is welded steel with ordinary snail shape. Single suction fan casing made of two different forms: №8 ~ 12.5 made the overall structure of the cabinet. Quarter №14,16 housing can be removed. For induced draft fan boiler fan, snail-shaped plate side in Ash opened the door, while properly thickened y47211 Boiler Fan prevent soot wear and prolong life. Inlet: is convergent streamline the overall structure, bolted to the inlet side of the cabinet. Adjust the door: device that regulates the fan flow size. №8 ~ 12.5 identified by the 13 flower blade composition, are axially mounted in front of the air intake, the use of the external drive structure, rotating flexible. Adjustment range by a 90 ° (fully closed) to 0 ° (fully open). Adjust the position of the door pull, as viewed from the air inlet to blower y473, on the right. For right-hand fan, pull the push from bottom to top is fully closed to fully open direction. For L-blower to pull down the pull on the direction from the fully closed to fully open. In order to adjust the door to work all parts of Boiler Fan y651, it must be well lubricated. For fan damper, using calcium sodium grease lubrication. For Fan, due to higher gas temperature, using molybdenum disulfide grease high temperature (260 ℃) grease lubrication ensures operation at high temperature. y548 Boiler Fan, Boiler Fan, Tang Hao Hao Teng fan by fan Manufacturing Co., Ltd. Hebei. Hebei Teng Hao Fan Manufacturing Co. (www.thfengji.com) strong, credible, in Baoding fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Teng-ho into the brilliant fans and you work for a better future!
