Y8-39 ,9-38 Boiler Fan
Patent No.:
Y9-38 boiler centrifugal induced draft fan is to make industrial boilers at runtime variable condition fan can work in the high zone , in order to save energy and the development of energy efficient fans , organized by the Ministry of Machinery Industry jointly designed famous national fan industry , the National Economic Commission and the Ministry of Machinery Industry application , with high efficiency , low noise , the performance curve efficient wide area and so on.
The fan is equipped with economizer for ( preheater ) and the smoke and dust removal device 0.5 ~ 35t / h industrial boiler selection, where the inlet conditions similar performance but also suitable for those who can be selected , but the maximum inlet temperature shall not exceed 250 ℃.
Improvement of the Company 's overall style 9-38 boiler centrifugal induced draft fan , and its aerodynamic performance with the original machine the same, and the fan body , transmission, motor assembly in the same housing above the bottom of the base with a plurality of damping is flexible contact with the ground . Consumers do not need to order special foundation , placed on a solid flat floor or floor , took over power, you can use .
★ Type and Structure
A machine number
There 4,4.5,5,5.6,6.3,7.1,8,9,10,11.2,12.5,14,16 thirteen machine number ( machine number equal to the number of units multiplied by 100 mm impeller diameter ) .
2 Transmission
All gauges have a D drive mode , in which a machine number 7.1 and 8 C drive mode
Type C - motor through pulleys, belts, bearings Gearbox
D -type - motor via a coupling, transmission bearing housing
3 assembly type
3.1 fan can be made L (N) and D (S) two kinds of rotation type, direction from the motor , impeller counterclockwise (N) spin left-handed ; impeller clockwise (S) is right-handed .
3.2 the fan outlet in a horizontal position as a reference point , can be made 0 °, 45 °, 90 ° 135 °, 180 °, 225 ° six kinds of patterns.
3.3 regardless of type C or D type , fans are installed in all parts of the whole rack above the bottom of the rack is equipped with shock absorber soft contact with the ground , without a dedicated fan base .
Four major structural components
4.1 Impeller - by fans new and efficient theoretical design forward by the blades, front disc , rear disc and shaft plate welding components. Impeller material can be selected according to the requirements of different high-quality carbon steel, manganese steel or corrosion-resistant stainless steel . After molding machines with advanced balance static and dynamic balance calibration, so smooth and reliable operation .
4.2 chassis ( including the front cover ) - based on the design of the prototype steel reinforcing frame , rigidity and load carrying positive and negative pressure so that it greatly improved the performance , chassis body material is also different according to the demand of high quality carbon steel or corrosion can be corrosion of stainless steel .
4.3 transmission - from the main shaft , bearings , water- cooled bearing housing , coupling or pulley mechanism and other components .
★ installation , commissioning and maintenance
1 check - should be checked before installation whether there are internal debris blower , if so, to be clear ; steers the impeller, if there is virtually scratch phenomenon , found inadequacies must be timely adjustments intact.
2 Foundation - thickness not less than 300mm concrete floor surface basic level, plus put on the rack around and not less than 300mm above the surrounding floor about 100mm ( waterproof ) ; fans can carry the weight of the floor , roof .
3 Commissioning - damper shall be closed before starting the blower at no load condition starts to reach normal operating speed can be gradually open the valve until the rated condition. During operation should be strictly monitored current must not exceed rating. Fan running after 20 minutes should check bearing housing temperature is normal ( temperature rise shall not exceed the ambient temperature 40 ℃, surface temperature should not exceed 70 ℃).
4 Maintenance - fan maintenance must first shut down power ; according to the actual situation in due course replace the lubricant ( oil or grease ) ; increased vibration occurs when the fan , bearing temperature is too high , the motor current is too large body of overheating are not normal circumstances , should promptly identify the reasons for troubleshooting before running again.
