The following introduces the reasons for the poor suction of high-temperature fans. Currently, high-temperature fans have a very good practical application effect and have been used in various fields such as ventilation, dust removal, and cooling. Since the operation of the equipment mainly relies on the motor, there are specific requirements for the motor during use. What are the requirements for the motor in high-temperature fans?

High-temperature fanWhat are the requirements for the motor?
Currently, the actual application effect of high-temperature fans is very good, and they have been applied in various fields such as ventilation, dust removal, and cooling. Since the operation of the equipment mainly relies on the motor, there are requirements for the motor during use. What are the requirements for the motor of high-temperature fans?
1. The design standard for the motor's rated working performance should not be less than 120% of the required equipment. When the motor operates at full load, it should still run normally without damage when the frequency changes by 5% and the voltage changes by 10%.
2. Under the rated working voltage conditions, the motor current during startup needs to be maintained within the specified range. If the high-temperature fan equipment uses a multi-phase motor, its phase sequence should be marked on the nameplate in its junction box, and the rotation direction should be indicated with an arrow. Additionally, the design, manufacturing, and performance of the motor must meet the standards.
3. In different workplaces,High-temperature fanthe motors used for the equipment are different. For example, AC, asynchronous, and air-cooled motors can be used, but the motor insulation level must reach Class F, the temperature rise must reach Class B, and the protection level must reach IP54, with a power supply voltage of 380 volts/-10%, 50 hertz.
The above are the requirements for the motor when using high-temperature fans. Since the quality of the motor indirectly guarantees the effectiveness of the equipment, it is essential to check whether the motor meets our usage requirements when purchasing equipment. Of course, regardless of the equipment and accessories, we need to conduct regular inspections and maintenance during normal use to ensure that no problems arise during use and to extend the service life of the equipment.
What causes poor suction in high-temperature fans?
Sometimes in practical applications, high-temperature fans exhibit a time lag phenomenon in suction only during startup. We immediately look for the cause of the problem.
1. Check if the high-temperature fan duct is blocked (when the duct is blocked).
2. Confirm whether allHigh-temperature fanconnections are secure.
3. Check the dust on the hot air fan filter (excessive dust will affect suction).
4. Check for motor faults in the high-temperature fan.
5. Organize debris in the high-temperature fan water tank.
After completing the above checks, if the poor suction of the high-temperature fan cannot be resolved, please contact the manufacturer for assistance.
Today, I will introduce this to you. Thank you for watching. I hope the above information is helpful to you. If you have any other questions about high-temperature fans, you can contact our company. If you need to purchase high-temperature fans or centrifugal fans, etc., you can also contact our company.
