Type of fan

   1. The fan is made as a single suction and its driving is A type. There are more than 18 types of fan numbers which are4、4.5、5、6、6.3、8、9、10、12.5、14、14.5、16、17、18、19、20、21and 22.

2. The fan can be made of 2 types of rotation i.e, right and left. Viewing from one end of the motor, it is called as clock-wise fan if the impeller rotates clock-wise, shown as “right”, On the contrary, it is called as counter-clock-wise fan if the impeller rotates counter-clock-wise, shown as “left”.

3. The outlet position of the fan can be expressed from the outlet angle of the casing. It can be made 7 kinds of angles which are 0°, 45°,90°, 135°,180°,225°, 270°，from both “Right” and “left”.

 

Structure of the fan

Thefan mainly consists of impeller, casing inlet, Drivingand Bracket unit.

Casing: to be welded into a volute with normal steel plate.

Impeller: The fan blade is made up of 12 backward single leaf blades, which reduces the impact of the air flow, has good stability , and the motor is not easy to overload, which greatly prolongs the service life of the fan. This type of fan has high pressure coefficient, low speed and low noise, so its practicability is good. The maximum circumference speed of impeller diffuser shall not exceed 140m/s. The impeller, after being shaped, shall be balanced statically and dynamicaly and thus it guarantees a smooth operation.

Inlet: to be integrated into a convergent streamlined structure and bolted on the inlet side of fan.

Adjusting valve: a device used to regulate the flow rate of the fan, which is mounted at the front of the inlet. The adjustment range is from 0 degrees (full open) to 90 degrees (full closed). The switch position of the door is adjusted from the inlet direction to the right, and the right whirlwind machine is pulled from down to up direction from the bottom to the full open direction. For the left whirlfan , the wrench is pulled up from the top to the full open direction.

Driving unit—it consists of shaft, bearing box, rolling bearing, belt pulley or coupling.

Leakproof oil bearing box, the use of a joint type of oil ring to swing the high-speed rotating bearing oil to the inner wall of the bearing box flow back to the oil pool; In addition to convenient maintenance and preventing friction accidents, semi-open aluminum oil seal can be used to cut back some of the dilute oil along the shaft. The lateral pressure plate root blocks a small amount of dilute oil; The upper part of the bearing box is equipped with a ventilation plug to reduce the micro-positive pressure in the bearing box, ensuring no oil leakage and good dust protection performance.

Th e main shaft of the transmission part is made of high-quality steel. The fans are all rolling bearings and are lubricated with L-AN46 mechanical oil.

The fan is integrated or partitioned: the fan is disassembled and assembled into multiple components for transportation and installation.

The fan is convenient for installation and repair. The fan has two complete base shell and transmission group. The shell has a middle or vertical side. The disassembly is particularly convenient. The rotor can be lifted vertically. If only the impeller is replaced, it can also be disassembled axially.

Transmission mode: The fan is cantilever structure, convenient layout, belt wheel connection transmission, uniform transmission
