Axial fan use note some characteristics

Release Time：2021-07-20

Axial flow fans are widely used. Their process is relatively simple, their structure is compact, and they are easy to install. Compared with other types of cooling fans, the cost is considerable, so what should we pay attention to when we apply axial flow fans.
1. When the axial flow fan is installed, one person controls the power supply and one person observes the operation of the fan. If any abnormal phenomenon is found, stop the machine immediately for inspection. First, check whether the purpose of the rotating target is accurate and after the fan starts to run.
Should immediately check whether the running current is balanced, whether the current exceeds the rated current, if there is no normal phenomenon, should stop the axial flow fan to check, after five minutes of operation, stop the fan to check whether there is abnormal phenomenon, confirm that there is no abnormal phenomenon and then start the operation.
2. When the axial flow fan is started, the step-down start or full pressure start is allowed. When the full pressure starts, the current of the axial flow fan is about 5 to 7 times the rated current. When the step-down start is proportional to the square of the current, so when the power grid capacity is insufficient, the step-down start should be adopted.
3. When the axial flow fan reaches the normal speed, it should detect whether the fan current is normal. The operating current of the fan cannot exceed its rated current. If the operating current of the axial flow fan exceeds its rated current, check whether the voltage supplied to the fan is normal.
The axial fan is fixed in the proper position and moves the air. Features: Small axial fan: low power consumption, fast heat dissipation, low noise, energy saving and environmental protection. Because of its small size, it is widely used. Large axial fan: simple structure, Stable and reliable, low noise, large air volume, and wide range of function options.
A diagonal flow fan/mixed flow fan, a fan between an axial flow fan and a centrifugal fan, the impeller of the diagonal flow fan allows the air to perform both centrifugal and axial motion, and the air motion in the casing axial flow fan mixes axial flow and centrifugal motion, combining the functions of an axial flow fan and a centrifugal fan, although it looks more like a traditional axial fan.
The curved plate-shaped blades are welded to a tapered steel hub, and the flow is changed by changing the angle of the blades in the inlet housing upstream of the impeller. The housing can have an open inlet, but more commonly has a right-angle bent shape so that the motor can be placed on the outside of the pipe. The drain housing expands slowly to slow the flow of air or gas and convert kinetic energy into useful static pressure.
