SE-A125 Variable Frequency Pipe Fan
Using Variable Frequency Drives (VFD`s) for Industrial Ventilating and Exhaust Fans Motors Operating on Variable Frequency Drives (VFD`s) Today, most standard NEMA Premium Efficiency motors are designed with characteristics that enable use with VFD`s on variable torque loads such as the majority of fan applications. These motors will be labeled as either [Inverter Ready" or [Inverter Rated", depending upon the motor manufacturer. Circular duct blower with wing-shaped backward-tilt impeller, high-speed operation of gas hydromechanics to play, so the energy efficiency is very high, up to 70%, that is, with a small motor power transmission of large wind, which is normal Fan centrifugal fan can not achieve the effect. Therefore, both the fan duct energy-saving and strong winds. Ultra-high pressure can take tens of meters of pipe concentrate ventilation, the main characteristic of the pipeline fan is the pressure. Replace the traditional ventilation equipment. Fan vibration-free, dynamic balance of less than 0.17g, only the standard value to ensure the superior quality fan, imported metal impeller or PP plastic perforated in accordance with the airfoil, which is characterized by strong rigidity, high temperature, environmental protection, air volume Large, but also to a certain extent reduce the noise.
Round tube fan core with an external rotor motor, its life depends on the bearing, the motor uses imported single deep groove ball bearings, external rotor motor compact structure, small size, energy efficient, pure imported bearings, 120 ℃ automatic parking hot Protection, high-quality copper winding and so on. 24h continuous operation can be more than 30,000 hours.
The product detail:
System impedance of equipment
In accordance with the internal construction of the equipment to be called. The resistance will appear when passing air through the equipment
This will cause reduction of stationary pressure during the ventilation and is called the system impedance.
Consequently,it becomes necessary for us to give stationary pressure value higher than the impedance for performing ventilation to the equipment system impedance can be given using the following formula:
Δ P=Reduced pressure(mm-H2O)
Δ P=KQn K5 Constant
N=index to be determine by air flow
N=2:Turbulent flow (Normally n=2)
The constant K here cannot be determined unless measure it by physically equipment.
Selection of the Fan
The selection of fan is done in according with following steps:
a) .Estimate the heat value (kw)of the heat source.
b) Determine the allowable temperature rise value Δ T
c) Assume the approximate ventilation volume in according with Formula(1)
d) Assumption of system impedance based on the ventilation of internal equipment of past data
e) Decide on the fan by referring to the Characteristic curve in Figure 2 from your catalog
f) Determine the adaptability of the fan by physically installing it is the equipment and measure the air temperature rise value Δ T or draft volume Q. if draft volume Q is insufficient, It is caused by the high system impedance , so it advisable to replace it with a higher quality fan
Measurement and measures against the Noises
Measurement of Noises
Measure it at 1.0 meters from the machine plane (at the central line of the air inlet )according to JIS-B8330(A characteristics)
Measures against Noises.
Although our fan motors are designed with special consideration of noises,sometime,it still can be affected by the user` s machine design to a large extent , so our attention is drawn to the following points:
a. Keep some distance between the object to be cooled and the inlet of the far. (Figure a -1)
b. When fittings are used ,pay attention not to cross each other with a spring .(Figure b -1)
c. When more than two fans are used, please keep then apart.(Figure c -1)
d. When finger guide is used, please keep it separated from the fan (We have kept some for this purpose.)
Technical information of fan motor
Measurement of air volume and static pressure
In our company we have been measuring the air volume using the multi - nozzle chamber air volume measuring device of automatic recording type,which is in conformity with the highly reliable AMCA specifications(USA).
The error rate is below 1% theoretically.(based on AMCA),Also it is possible to measure the characteristics of the suction side as well as the blowing side ,( 54146766, 54145670, 54144285, 54144272, 54142882, 54141828, 54141732, 54140759,the values in catalog show the characteristics of the blowing side .)
