Motor Starting Torque Moments of Inertia (Lb-Ft2)

When selecting a motor for an industrial process fan, the motor must be capable not only of driving the fan at operating speed, but also must be capable of accelerating the fan wheel, shaft and drive to the operating speed.

The fan performance tables and curves in this catalog show the brake horsepower required to operate the fan once it is brought to speed. For applications requiring a large air volume at a low static pressure, the BHP required at the fan’s operating RPM may not be sufficient to initially start the fan. If the time required to bring the fan to speed is excessive, the motor winding insulation can be damaged due to excessive temperature rise and the life of the motor seriously affected.

For a belt drive industrial process fan the required motor starting torque capability can be expressed by the following formula:

=WR

= The moment of inertia that the

Effect of Air Density

Ratings in the fan performance tables and curves of this catalog are based on standard air (clean, dry air with a density of .075 pounds per cubic foot, barometric pressure at sea level of 29.92 inches of mercury, temperature of 70°F.). Selecting a fan to operate at conditions other than standard air requires an adjustment to both static pressure and brake horsepower.

A cubic foot of air has a constant volume regardless of temperature or elevation. However, air density changes with non-standard temperature or elevation. Therefore, when selecting a fan to operate at a non-standard air density using standard air density tables and curves, corrections must be made to parameters affected by air density. These parameters are static pressure and brake horsepower.

For example, a size 26 IPO industrial fan is to deliver 15,000 CFM at 16 inches static pressure. Elevation is 2000 feet, temperature is 400°F.

The 16 inches static pressure refers to the static pressure at the operating air density, in this case at 2000 feet, 400°F. Intuitively, we realize that at higher than standard elevations and temperatures, air density will be lower than standard. Therefore, we must determine what static pressure at standard air density will equate to 16 inches static pressure at our operating density. Since standard air density is greater

than operating air density in this case, we would expect the corrected static pressure to be greater than the operating static pressure.

The accompanying table gives air density correction factors for non-standard temperatures and elevations.

The example below shows the relationship of fan performance at sea level and at 2000 ft. elevation and 400°F.

AIR DENSITY CORRECTION FACTORS

Elevation (Feet Above Sea Level)

EXAMPLE

The following example shows how to properly select the fan described above:

1. Since the air volume delivered by the fan is not affected by density, airflow remains 15,000 CFM.

2. Determine correction factor from chart for an elevation of 2000 feet and air temperature of 400°F. The correction factor is 1.75.

3. Multiply the specified operating static pressure by the correction factor to determine the standard air density equivalent static pressure (Corrected static pressure = 16" x 1.75 = 28" static pressure).

4. Refer to the fan performance table for a 26 IPO. At 15,000 CFM and 28" static pressure: Fan RPM = 1560, BHP = 111.

5. 1560 Fan RPM is required to produce the desired performance.

6. Since the horsepower selected refers to standard air density, this must be corrected to reflect actual BHP at the lighter operating air. Operating BHP = standard BHP ÷ 1.75, or 111 ÷ 1.75 = 63.4 BHP.

If a fan is selected to operate at high temperatures, the motor must be of sufficient horsepower to handle the increased load at any lower operating temperature where the air is more dense. Assume the air entering the 26 IPO fan at start-up is 0°F. For 0°F and 2000 feet elevation the air density correction factor is 0.94. BHP at 0°F = 111 ÷ 0.94 = 118.1, therefore, a 125 HP motor is required.

Minimum Conveying Velocities for Materials

The following chart lists recommended conveying velocities for various industrial materials. The chart is intended to be used as a reference. That is, these velocities are not guaranteed to produce trouble-free operation of a material conveying system. Instead, they offer a guide as to the velocities that can be expected when conveying a particular material.

Special considerations should be made when selecting a velocity for material conveying. If the velocity in the ductwork is too high, erosion of elbows and transitions in the ductwork will likely occur. If the velocity in the ductwork is too low, the material in the airstream will not be conveyed. Instead it will settle out and cause plugging.

The nature of the material being conveyed must also be considered. A particularly corrosive material can deteriorate fan components. Long, fibrous material may wrap itself around the fan wheel and shaft and reduce fan performance. A wheel or housing that is continually bombarded by particles during operation will increase maintenance while decreasing the fan life. Proper cleaning of the fan and removal of accumulating material from the housing can prevent these problems from occurring.

Direct Drive Arrangements

Greenheck offers direct drive Industrial Process Fans in two arrangements, 4 and 8.

Arrangement 4 fans involve mounting the fan wheel directly to the motor shaft without any additional bearings to support the overhung fan wheel. For this reason, arrangement 4 fans are limited to IPO and IPW wheels in sizes 5 - 19, standard duty construction, and 11 - 19 in heavy duty construction. Fan sizes larger than 19 have wheels which are too heavy to be supported by the motor bearings alone.

Arrangement 8 fans are similar to an arrangement 1 fan in that they share the same drive pedestal which supports the overhung fan wheel with two externally mounted bearings. The arrangement 8 adds an extended motor base to allow direct coupling of the fan and motor shafts. This arrangement is available in fan sizes 5 - 41 in standard duty construction and 11 - 41 in heavy duty construction.

Dimensions for arrangement 4 and 8 fans are based on specific performance points and motor requirements. Consult the factory for submittal drawings.

Direct drive fans offer distinct advantages over belt drive fans. Advantages of arrangement 4 fans include:

• No belts to tension or maintain.

• No external bearings to grease.

• No drives to cause horsepower loss.

Advantages of arrangement 8 fans include:

• No belts to tension or maintain.

• No drives to cause horsepower loss.

• Shaft couplings offer high resistance to grease, dirt, oil and moisture.

• Rarely a need to remove and realign shafts of connected fans.

• Optional heat fan packages for high temperature construction up to 800° F.

• Motors can be serviced or replaced easily.

Direct drive fans require a special design for each application. One choice is to use a synchronous motor speed and a full width fan wheel. This choice offers the least expensive of direct drive options because no wheel or housing modifications are necessary. A second choice would be to use a Variable frequency drive with a full width fan wheel. Again, no modifications are made to the fan wheel or housing reducing additional engineering costs. Also, any stable operating point along the fan’s operating curve is obtainable using the variable frequency drive. A third choice is to use a synchronous motor speed with a partial width fan wheel.

The following drawings show the differences between an arrangement 4 and an arrangement 8 direct drive industrial process fan.

Sample Fan Selection

The purpose of these two pages is to demonstrate the manual industrial process fan selection process. These pages also contain helpful tips to check your fan selection as well as a step by step set of instructions on how to use this manual to properly select an industrial process fan.

An important point to remember when manually selecting an industrial fan is that more than one fan is available to meet the desired performance (CFM and Ps). Selection criteria such as unit size, efficiency, speed, outlet velocity, horsepower, or construction material may also dictate which fan is chosen.

Step 1

Fan Selection Procedure

STEP 1

Enter the Performance Table with the desired CFM and Ps. Obtain the fan RPM, operating BHP and Duty.

EXAMPLE: For this example we will use 8600 CFM at 9.0" Ps. This gives us a fan RPM of 1153 requiring 17.6 BHP, in standard duty construction.

NOTE: The motor size can be compared to the Maximum Motor Frame Size chart found at the top of the Performance Table. Motor frame sizes are based on fan arrangement.

Step 2

STEP 2

Enter the Fan Curve with the desired CFM and Ps. Obtain the fan Operating Point, % WOV, Operating HP, Free Air HP and verify Fan Duty using the curve shading.

EXAMPLE: For this example the fan operating point is at 41% WOV using a 20 HP motor. The Free Air HP is 30 and can be found by following the Fan RPM curve down to 0" Ps.

NOTE: The Free Air HP for industrial fans must be considered because the wheels have overloading characteristics. This means the required

motor horsepower increases as static pressure decreases.

21 IPA

STEP 3

Enter the Fan Sound Table with the Fan RPM from the Performance Table and the % WOV from the Fan Curve. Obtain the eight octave ratings for inlet (Lwi) and outlet (Lwo) sound power.

EXAMPLE: For this example, the eight octave ratings are circled in the Fan Sound Table.

NOTE: The exact % WOV for your desired performance point can be found using the equation at the top of the Fan Sound Table if it is not published. The eight octave ratings can then be found using interpolation.

% WOV = (CFM X 100) / (RPM X 18.2)
