  Details:
1.Use
 
The W5-48 type high temperature boiler centrifugal fan is designed for a 1t / h / 20t / h industrial boiler burning all kinds of coal and equipped with smoke and dust removal device. The same inlet condition and similar performance may be used, but the maximum temperature shall not exceed 600 ℃; before the high temperature fan, A dusting device with an efficiency of not less than 85% must be installed in order to reduce the dust content of the flue gas entering the fan and increase the fan's life.
 
2.Type type
 
The fan is made into single suction , and the machine number is No4 , 5 , 6.3 , 8 , 10 and 12.5 altogether six machine numbers .
 
Facing squarely from one end of the motor, the impeller rotating clockwise is called right-hand fan, expressed as "right"; vice versa,
 
Left cyclone, expressed as "left".
 
The air outlet position of the fan is expressed by the outlet angle of the casing. "left" and "right" can be made into six kinds of angles: 0 °45 °45 °90 °135 °180 °T 225 °.
 
3.structure
 
At present, there are many series of industrial boilers, the quality of burning coal is not good or bad, the resistance of dust collector used is different, the air volume and pressure of required fan are different greatly. In order to adapt to the above situation, considering the economy of fan, the triangle belt type C) drive is adopted. In this way, not only can one machine number adopt different rotational speeds to meet the requirements of all kinds of dust removers for the same tonnage boiler, but also the fan series and machine number can be reduced, and it is also convenient for the use units to select different rotational speeds according to the actual situation. To obtain the required air volume and pressure.
 
The fan is mainly made up of impeller, casing, inlet, regulating door and transmission group.
 
Impeller-by backward tilting plate blade 12 pieces, welded to arc wheel cover and flat wheel disc. Through static, dynamic balance test correction and overspeed operation experiment, so the operation is stable and reliable, high strength.
 
Shell-welded with steel plate to form cochlear shape above "left" and "right". There are also ash removal doors open on the cochlea plate to facilitate the removal of ash accumulated on the blade and the housing, and to ensure the balance and aerodynamic performance of the impeller.
 
Intake-convergent streamline structure, bolted to the inlet side of the fan.
 
Regulating valve-adjusting door is petal-shaped no _ 4N _ 4C _ (6.3) is 9 pieces of No8 or more than 11 pieces, axial installation in front of the inlet, because of the use of an external transmission structure, Flexible and convenient transmission. The position of the lifting handle of the adjusting door from 0 °(all open) to 90 °(completely closed): from the direction of the inlet to the right side, for the right-handed fan, the lifting handle from the bottom to the top is completely closed to the full open direction, and for the left cyclone, In order to make the adjustment door work normally, it must be lubricated very well. The grease adopts molybdenum disulfide high temperature 260 ℃) grease, the fan can still be moistened when running at high temperature.Slippery.
 
Transmission group-consists of spindle, bearing box, belt pulley, etc. The spindle is made of high quality steel. The fan adopts rolling bearing and water-cooled integral bearing box. Therefore, water transmission pipes must be installed, and the water consumption varies according to the environment. The bearing box is equipped with a thermometer and an oil level indicator, the lubricating oil is 30# oil, and the oil quantity is based on the oil level indicator.
