고온 연기 배기 팬 Y9-38 탈황 원심 팬

High temperature smoke exhaust fan Y9-38 desulfurization centrifugal fan Product Description Use Y8-39, and Y9-38 two series of boiler centrifugal fans are designed to enable the induced fans to work in the high-efficiency zone when the industrial boilers are operating under variable conditions, so as to achieve the purpose of energy saving. The high-efficiency and energy-saving products jointly designed by famous experts in the industry and promoted by the State Economic Commission and the Ministry of Machinery Industry have the advantages of high efficiency, low noise, and a wide high-efficiency zone of the performance curve. This fan is suitable for 0.5-35t/h industrial boiler equipped with an economizer (preheater) and smoke and dust removal device. The maximum inlet temperature shall not exceed 250°C. A dust removal device with a dust removal efficiency of not less than 85% must be installed in front of the induced draft fan to reduce the dust content of the flue gas entering the fan, which not only reduces the environmental pollution of the flue gas but also reduces the Air wear on the fan is beneficial to improve the service life of the fan form. The fan is made of single suction and has two forms of clockwise rotation or counterclockwise rotation.     Detailed Photos Structural features The fan is composed of the impeller, casing, air inlet, transmission group, regulating door, and other components. (1) The impeller material is forward curved blades with alternate lengths and short lengths.   After the impeller is formed, it is corrected by static and dynamic balance, so the operation is stable and reliable. (2) The casing is welded into a volute casing with steel plates.   A dust-cleaning door is opened on the snail plate.   It is convenient to remove the dust accumulated in the blade and the casing and ensure the balance and aerodynamic performance of the impeller. (3) The air inlet is made into a convergent and streamlined overall structure, which is fixed with bolts and the front cover plate. (4) The transmission group consists of a main shaft, a water-cooled bearing box, and a coupling.   The main shaft is made of high-quality steel.   Rolling bearings are used, and the bearing housing has two forms: integral type and partial type. (5) The adjusting door is a device used to adjust the flow rate of the fan.   The adjusting door blades are petal-shaped and axially installed in front of the air inlet.   Due to the adoption of the external transmission structure, the rotation is flexible and convenient. Product Description Structure Impeller Type: Structure Impeller Type: Backward/Forward/radial blade Driving  Mode: Direct/belt/Coupling drive train System Type: Single inlet type, Overhang type Cooling Type: Air cooling/Circulating Water cooling Bearing Lubrication Methods: Grease lubricating/Oil bath lubrication  Advantages of centrifugal blower    1)High strength wear-resistant impeller anti-leaking bearing box. 2)Transmission part group consists of main shaft, bearing box, rolling bearing, pulley or coupling, etc.  3)Inlet and outlet flexible joints, dampers.  4)Inlet valve, bearing temperature and vibration device sensors, impeller cleaning nozzle are optional.  5)With single suction, backward of monoblock type blades impeller have good aerodynamic performance and reliability of smooth operation.

The following points should be paid attention to durning the process of installation:   (1) Smear some graese or machine oil on some junction surfaces in order to prevent rusting, and reduce the   difficulties when moved.   (2) When fixing the scew bolts on the junction surfaces,if there are Positioning pins,fix the Positioning pins first   then the screw blots.   (3) Check the inside of the chasssis and other cases to make sure that no tools and other substances are left in it .   Product Parameters Techinical Parameters(Other parameters welcome email consultation):              Application  industrial systems such as Coal-fired power, Metallurgy, Papermaking, Cement and Glass production, Chemical industry, Material handling, Sewage treatment, Waste incineration, Subway ventilation, environment protection, mine, metallurgy, petro-chemical, tunnel,Industrial boiler and Dust removal systems etc. , and wind tunnel FAQ FAQ 1.Q: What parameters need to be provided when you design the industrial centrifugal fans?
