Axial flow fan box characteristics classification operation attention

Release Time：2021-07-20

According to the characteristics of the axial fan box to make the following classification.
According to the classification of raw materials: steel fan, glass fiber reinforced plastic fan, fan, PP fan, PVC fan, magnesium alloy fan, aluminum fan, stainless steel fan, etc., according to the use of classification: explosion-proof fan, anti-corrosion fan, explosion-proof anti-corrosion, special axial flow fan fan and other types.
According to the application request classification: pipeline type, wall type, post type, fixed type, rain and dust proof type, mobile type, motor external type, etc.
Equipment and equipment methods can be divided into: belt drive type, motor direct-coupled type, when the axial flow fan box is started, the current of the motor will be 5-6 times higher than the extra, which will not only affect the service life of the motor axial flow fan and consume more Electricity. In the design of the system, there will be a certain margin in the selection of the motor. The speed of the motor is fixed. However, in the process of practical application, the axial flow fan sometimes needs to operate at a lower or higher speed. Therefore, it is necessary to carry out frequency conversion transformation. The frequency converter can complete the soft start of the motor. After changing the input voltage frequency of the equipment, the intention of energy saving and speed regulation can be reached, and the maintenance functions such as overcurrent, overvoltage overload can be supplied to the equipment.
Before using the axial flow fan, check the gap size of each part of the fan, check whether the migration change part and the solid part have scraping phenomenon, check whether the rotation direction of the impeller is consistent with the sign, whether the wiring of each part, whether the instrument is actually abnormal, whether there is water leakage, electric leakage, oil leakage, peculiar smell, abnormal noise, abnormal vibration, looseness and other abnormal phenomena, if any, it should be used after elimination.
In the process of ending the utilization of axial flow fans, even if it adopts economical recuperation methods, it is necessary to introduce the skills of predecessors to end the large, efficient and energy-saving axial flow fans, replace the old axial flow fans in utilization, and use the axial flow smoke exhaust fans with low efficiency and no transformation value at any time. It is necessary to adopt gradual elimination measures, perform the use of efficient and energy-saving axial flow fans, and transform offset axial flow fans, and to send high-efficiency series of energy-saving fans, and in the national axial flow fan economy in all areas of the end of a certain implementation of the use.
When the axial fan starts, the current of the motor will be 5-6 times higher than the rated value, which will not only affect the service life of the motor but also consume more electricity. The body axial flow fan system will leave a certain margin in the motor selection during planning. The speed of the motor is firm and stable, but in the actual utilization process, it occasionally needs to run at a lower or higher speed. Therefore, it is extremely necessary to end the frequency conversion transformation. The frequency converter can realize the soft start of the motor, change the input voltage frequency of the equipment through the process to achieve the purpose of energy saving and speed regulation, and can supply the equipment with overcurrent and overvoltage, overload and other protection functions.
